Abstract

Background

In completely edentulous patients, maintaining the patient’s temporomandibular joint (TMJ) health and intraoral components is very essential, which can be achieved by an accurate interocclusal record, which can be taken by various materials and also at various stages. Simulation of the temporomandibular joint anatomy and mandibular movements is possible on a semi-adjustable articulator, which is widely used in prosthodontics. Transferring the record on articulator is a critical step in the fabrication of complete dentures, so it should be done precisely to reduce chair side time and also to avoid complications for patients. This study examines which material is more accurate and records which stage gives more precision by comparing the Condylar guidance on radiographs. This is because it is a relatively consistent bony landmark and can be used to correlate with clinical methods in terms of verification. The objective is to determine the inter occlusal records created during the Jaw Relation stage and Try-in using reinforced wax and Polyvinyl siloxane and compare these values to the condylar guidance obtained by orthopantomogram (OPG).

Methods

Recording the Condylar Guidance value on OPG by tracing the Glenoid fossa, Articular eminence, and the Frankfurt Horizontal Plane. Followed by conventional steps in making complete dentures at jaw relation and try-in stage. We will record values of condylar guidance with the two different Interocclusal record materials.

Expected result

It will help the clinicians to gain knowledge about obtaining precise condylar inclination angle by using suitable interocclusal record materials.

Conclusions

This study will help us to obtain condylar inclination, which in turn helps the patient’s satisfaction as it preserves the intraoral components and health of TMJ.

Introduction

Background and rationale

In order to achieve a comfortable prosthesis that will last several years and maintain the patient’s Temporomandibular joint health and intraoral components, proper interocclusal recording should be followed during the procedure.¹ In completely edentulous patients, the slope of articular eminence on a digital panoramic radiographic image will be traced, which will be utilized in the semi-adjustable articulator’s programming.²

Mandibular movements can be mimicked with the help of a semi-adjustable articulator. Due to their ease of handling and programming, they are frequently used in prosthodontics.³ Mounting of the master casts on an articulator is crucial step in the treatment of the completely edentulous patient.¹ In articulator programming, the device is modified to mimic the patient’s temporomandibular joint structure and movement patterns of the patient. As a result, it acts as a patient when the patient is not present.³

Condylar guidance is described as mandibular guidance generated by the condyle and articular disc traversing the contour of the articular eminence-GTP-9.⁴ In the event that condylar guidance, the mandibular movements are not accurately recorded, occlusal interference will occur. The time it takes to adjust dentures might go up as a result. Therefore, it is crucial to capture the maxillomandibular relationship accurately.⁵

Condylar inclinations are provided by semi-adjustable articulators in two different ways: horizontally and laterally. Hanau’s formula can be used to calculate the lateral condylar inclination from the horizontal condylar inclination (HCI), which is determined with protrusive interocclusal records, or it can be done with individual lateral records.⁵

On semi-adjustable articulators, The condylar guidance has been found to be unreliable when recorded and reproduced.⁵ There was a notable variation amongst the condylar guidance angle recorded successively by different practitioners, among multiple record materials, and amongst various articulators. This can be avoided by taking interocclusal records at various points in an edentulous subject, such as after teeth have been arranged or during jaw relation (Arrow point tracing). It is observed that records taken after teeth arrangement are much more accurate. The values for the individual’s condylar guidance are calculated using these records.³

Radiographs can also be used to measure condylar guidance. When compared to clinical methods, it is more reliable because it uses consistent bony landmarks and can be standardized. These pictures offer composite skeleton representations in the sagittal plane. In semi-adjustable articulators, condylar guidance inclination will be set using the outline of the eminence.³

Therefore, in the current research, a comparison of condylar guidance measurements will be made using records intraocclusally and digital orthopantomograph images in edentulous subjects. Interocclusal recording medium should be capable of reproducing the details of the occlusal surface as well as preserving the rigidity and accuracy of the materials for re-use more than once. For the purpose of keeping inter-occlusal records, there are several materials that can be used.¹ In this study, we will also compare the precision and repeatability of two interocclusal recording materials, that is, Reinforced wax and Polyvinylsiloxane (Jet bite), in determining the condylar inclination values in semi-adjustable articulators.

Aim & Objectives

Aim

To evaluate the condylar inclination values obtained using panoramic radiographic images and to compare those values of condylar inclination with the values obtained using two different interocclusal recording material in semi-adjustable articulator during jaw relation and try-in stages.

Objectives

• To determine condylar guidance values using OPG image.
• To evaluate the condylar guidance values utilize records intraocclusally taken during Jaw Relation stage with Reinforced wax and Polyvinyl siloxane (jet bite).
• To evaluate the condylar guidance values utilize records intraocclusally taken during Try-in with Reinforced wax and Polyvinyl siloxane (jet bite).
• Comparing the condylar guidance obtained using OPG with that determined during the Jaw Relation and Try-In.

Study design: Analytical observational study.

Study setting

The upcoming research work shall be done in Department of Prosthodontics Crown & Bridge at Sharad Pawar Dental college, Sawangi, Wardha.

Study participants

The study will be conducted on the patient reporting to the Department of Prosthodontics crown & bridge, with the chief complain of completely edentulous upper and lower arches and who are consider for complete denture prosthesis at Sharad Pawar dental college and hospital, Sawangi (Meghe), Wardha.

Inclusion criteria

• Participants with no teeth at all and has well-defined ridges
• Patient should have class I ridge relation
• Interocclusal space should be minimum between 1-3 mm

Exclusion criteria

• People who exhibit symptoms of neuromuscular and temporomandibular joint conditions.

Methods

Written informed consent from the patient will be obtained, After obtaining informed consent, the following procedure will be done:-

Evaluation of Condylar Guidance value by OPG

Orthopantomograph will be taken with the regular exposure, and tracings will be done, Marking the Glenoid fossa (Superior curvature), Articular eminence (Inferior curvature), and the Frankfurt Horizontal Plane (FHP) (Figure 1). The angle formed by joining the lines will be the horizontal condylar guidance angle for that patient. The condylar guidance values on both the right and left sides are recorded. This will be recorded for all the subjects.

Figure 1. Tracing of line AB joining height of superior curvature A and inferior curvature B, representing inclination of the articular eminence. XY is parallel to FHP. C is the angle made by the intersection of the mean curvature line and horizontal reference line.

Conventional steps of complete denture

Preliminary Impressions will be taken with a modeling compound, and Impressions will be filled with dental plaster, a positive replica of the primary impression known as the preliminary cast. On which wax spacer and custom tray will be made. Using the low-fusing impression compound, Border moulding will be done, and Final impression will be taken by zinc oxide eugenol paste. This impression will also be poured with dental plaster, and the cast obtained will be the master cast. A temporary record base will be made on it, along with the occlusal rims.

Determination of values of condylar guidance with the Interocclusal record material during the Jaw relation stage

The jaw relation will be recorded using standard techniques. Face bow transfer will be completed, and the maxillary cast will be oriented on the articulator with the centric relation record. The mandibular cast will be related to the maxillary cast and mounted on the articulator’s mandibular component. Tracers will be affixed to the rims of the maxilla and mandible. The subject will be seated in an upright position and, he/she will be trained for mandibular movements. Once the dentist is satisfied with the patient’s mandibular movements, the tracer plate will be ready to document.

The patient will be asked to retrude the mandible in centric relation once a distinct arrow point tracing with a sharp apex has been made, and the interocclusal recorded using reinforced wax and polyvinyl siloxane (jet bite) will be taken. The rims will be held intraorally till interocclusal material is set. When the mandibular jaw is in the centric relation, the head of the condyle is positioned anteriorly and superiorly within the mandibular fossa/glenoid fossa as possible. A protrusive interocclusal record will also be made by instructing the patient to protrude 6mm of distance from the apex of the arrow, and it will be marked. This will be programmed on hanu-articulator. Articulator programming simulates TMJ anatomy and movements of the subject. Thus, it serves as a subject in the absence of the subject. Horizontal condylar guidance adjustments will be freed by releasing the locknuts.

Determination of values of condylar guidance with the Interocclusal record material at the try-in stage

Teeth arrangement will be done, the try-in procedure, and interocclusal records will be made using two different interocclusal record materials namely, Polyvinyl siloxane and Reinforced wax. As it is challenging to maintain jaw stability at a 6mm protrusion position, we will make a wax indentation with bite registration aluminium wax prior, which will help the subject to maintain the desired protrusive jaw position. The articulator’s upper member will be moved forward by about 6 mm after the try-in procedure and then closed in that position. The trial dentures will then be placed on the articulator. The interaction of the upper and lower midlines and the horizontal relationship between the lower and upper anterior teeth will be closely scrutinized. The locknuts will be fixed in that position. After proper training of the patient, we will register interocclusal records using bite registration paste and reinforced wax and hold the records in the mouth till the material gets hard.

The programming of the articulator

The trial dentures will be put on the articulator, and the interocclusal records will be used for programming. The maxillary cast will be constructed in two parts using a horizontal division method to evaluate the condylar guidance angulation. The condylar guidance values will be logged for both the interocclusal material reinforced wax and polyvinylsiloxane for each side, right and left of the condyle.

The condylar guidance values obtained will be subjected to statistical analysis. The procedure will be done by a single operator following a standardized protocol to minimize measurement bias.

Variables and data measurements

Outcome: The expected outcome of the study is that it will help the clinicians to get knowledge about obtaining precise condylar inclination angles. Since the study focuses on two different materials used for interocclusal records at two different steps, the results will provide more insight about the material and the step that can offer better outcomes in terms of achieving closer condylar inclination as that of the patient.

BIAS: Bias will be minimized as patients are randomly selected from the Outpatient Department of Department Prosthodontics Crown & Bridge, of Sharad Pawar Dental College and Hospital, Wardha.

Sample size calculation

Formula Using Mean difference

n \geq \frac{Z_{1 - \frac{α}{2}} + {Z_{1 - β}}^{2} (σ_{1}^{2} + σ_{2 / r}^{2})}{{(μ_{1} - μ_{2})}^{2}}

Where;

Z1-α/2 is level of significance at 5% i.e., 95%

Confidence interval = 1.96

Z1-β is the power of test = 90% = 1.28

Primary variable:

Mean \pm SD . (Articulator Group) = 25.7143 \pm 10.15944

Mean \pm SD . (OPG Group) = 38.777 \pm 2.56 .

Pooled std Dev . = (10.15944 + 2.56) / 2 = 6.359

As per reference articles.

N1 = 2^{*} [(1.96 + 1.28) 2 (13.0557) 2] / (6.359) 2 = 7

Minimum Total samples required = 7 per Group.

Minimum Total sample size is 14.

Statistical analysis

Statistical analysis will be done with the aid of Independent t-test. Analysis of variances (ANOVA) will be applied for analysis. The software that will be used in the analysis will be the SPSS 27.0 version.

An unpaired t-test will be used comparing condylar guidance between radiographic images and jaw relation/try-in, if data follows a normal distribution, or the Mann-Witney Test if it’s not. Comparing across different stages and materials, the Repeated Measures ANOVA is appropriate for normal data, while the Friedman Test should be used for non-normal data.

Dissemination

The scope of this study is to provide dental practitioners with a method to effectively and precisely record condylar guidance, which will not lead to maximum intercuspation interference while doing lower jaw movements. This will contribute to meet needs of the patient in accordance with the operation and durability of the denture in the oral cavity.

Study status: The study has yet to started.

Discussion

Condylar inclination refers to the angle at which the mandibular condyle moves along the articular eminence, playing a key role in mandibular movements and occlusion. Its prosthetic significance lies in its importance for setting dental articulators during the fabrication of dentures. Proper adjustment of condylar inclination ensures the prosthesis replicates natural jaw movements, leading to better occlusal stability, balanced occlusion, and prevention of premature contacts, ultimately enhancing the comfort and function of dental prosthetics. A recent study from 2023 by Gheedle and John compared horizontal condylar guidance in edentulous patients using protrusive interocclusal records, orthopantomography (OPG), and cone-beam computed tomography (CBCT).⁸ The study found that CBCT and OPG methods yielded similar results and provided reliable measurements for condylar guidance. Konark et al. in 2021 evaluated sagittal condylar guidance using panoramic radiographs and lateral cephalograms in 82 dentulous subjects. The study noted that panoramic radiographs provide a significant correlation between both right and left condyles, supporting their use in clinical settings to ensure better accuracy and reduce patient exposure.⁹ In 2021, S.R. Keerthana studied an article to evaluate the reproducibility of condylar inclination and concluded that HCI values varied with respect to the record material used.⁵ R. Venkateshwaran in 2014 The relationship amongst the angle of horizontal condylar inclination measured on a semi-adjustable articulator and the angle marked on a TMJ tomogram in a patient presenting with no teeth was investigated. He concluded that the horizontal condylar inclination, which is represented by the articular eminence marked on a TMJ tomogram image, has a mean difference of 5 degrees.² Another author 2013 studied the accuracy of articulator programming using radiographs and interocclusal records captured during the Arrow point tracing and Try-in stages. They noticed that reasonable condylar guidance values determined at the try-in stage were nearer to the average condylar guidance values determined on radiographs.³ Pragya Shreshta, in 2012, wanted to evaluate how the horizontal condylar guidance is measured clinically and radiographically. The CT scan and three clinical techniques—the wax protrusive record, Lucia jig record, and intraoral central bearing device were used to assess the condylar guidance. He came to the conclusion that the left and right HCG values were nearly identical. Particularly in comparison to clinical methods, the CT scan revealed higher HCG values, and all of the analytical methodologic values were comparable.⁶ In 2003, Jose dos Santos Jr (2003) studied this article to differentiate the condylar inclination angles between the protrusive wax record in a semi-adjustable Hanau articulator and the quick-set recorder for pantographic tracings. He determined that the protrusive wax record did not precisely reproduce the protrusive condylar inclination and that the pantographic tracer technique could do.⁷

Overall, the core structure and contents of this protocol appear well-developed. The manuscript focuses on comparing the condylar guidance values obtained from reinforced wax and polyvinyl siloxane interocclusal record materials, using panoramic radiographic images as a reference. However, the article ... Continue reading

The author mentions that the study will provide clinicians with knowledge about obtaining precise condylar inclination angles using the right interocclusal record materials. Including the results of the horizontal condylar guidance values at the jaw relation and try-in stage in the expected outcomes would also be desirable.
Please clarify the abbreviation "OPG" and explain which word it represents.

Introduction:

Regarding the background and rationale, I disagree with the statement that panoramic radiographic images provide more reliable values for condylar guidance compared to conventional methods. Panoramic radiographic images may exhibit significant deformation and distortion in the anatomic structures.
The stated objective of "Determining condylar guidance values using OPG image" is inappropriate for this study. In the Objectives section, the main purpose of the study should be articulated. It should be noted that the measurement of horizontal condylar guidance values using OPG images introduces bias compared to conventional methods, as the temporomandibular joint consists of hard and soft tissue structures. Therefore, using OPG images as a "control group" in this experiment is not valid.
The inclusion criteria should provide more specificity regarding the width and height of the remaining alveolar ridge for participants with no teeth.

Methods:

Consider using CBCT or lateral cephalometrics instead of OPG for the evaluation of the Condylar Guidance value. Additionally, provide a more detailed description of the method used to obtain horizontal condylar guidance values from the OPG image, allowing for replication by others.
Note that the articulator used is different from an actual patient. It is recommended to take the protrusive interocclusal record intraorally, rather than programming it on the articulator.
Clarify the material of the wax indentations used to determine the values of condylar guidance with the Interocclusal record material at the try-in stage. Also, correct the sentence: "The articulator's lower member will be moved forward by about 6 mm after the try-in procedure, and it will then be closed in that position." The movement can only be done on the upper part of the articulators.
Please provide information on where the data for the sample size calculation came from.

Discussion:

Ensure that the references used are up to date by checking and replacing them with more recent articles.

Is the rationale for, and objectives of, the study clearly described?

Yes
Is the study design appropriate for the research question?

Yes
Are sufficient details of the methods provided to allow replication by others?

Partly
Are the datasets clearly presented in a useable and accessible format?

Ans- Orthopantomogram, It represents Digital Panoramic Radiographic Images

Regarding the background and rationale, I disagree with the statement that panoramic radiographic images provide more reliable values for condylar guidance compared to conventional methods. Panoramic radiographic images may exhibit significant deformation and distortion in the anatomic structures.

Ans. Yes sir, I have consider this as a limitation of my study. The statement that panoramic radiographic images provide more reliable values for condylar guidance compare to conventional is taken from literature. Shetty S, Satish Babu CL, Tambake D, Surendra Kumar GP, Setpal AT. A comparative evaluation of condylar guidance value from radiograph with interocclusal records made during jaw relation and try-in: A pilot study. The Journal of Indian Prosthodontic Society. 2013 Sep;13:321-6.

The stated objective of "Determining condylar guidance values using OPG image" is inappropriate for this study. In the Objectives section, the main purpose of the study should be articulated. It should be noted that the measurement of horizontal condylar guidance values using OPG images introduces bias compared to conventional methods, as the temporomandibular joint consists of hard and soft tissue structures. Therefore, using OPG images as a "control group" in this experiment is not valid.

Ans. Yes sir, I will mention. Thank you. Sir, Bias will be eliminated as the same person will be evaluating the conventional method records as well as OPG tracing, patient will be taken from out patient department so bais will be eliminated their also And limitation of OPG image distortion is also consider.

The inclusion criteria should provide more specificity regarding the width and height of the remaining alveolar ridge for participants with no teeth.

Ans. Yes sir, I will specify in inclusion criteria. Patient should have class I ridge relation and interocclusal space should be minimum 3-4 mm

Consider using CBCT or lateral cephalometrics instead of OPG for the evaluation of the Condylar Guidance value. Additionally, provide a more detailed description of the method used to obtain horizontal condylar guidance values from the OPG image, allowing for replication by others.

Ans. Keeping economy and availability of machinery in clinic set up in mind OPG is chosen over CBCT and lateral cephalometrics. Method: On OPG we should trace the following points to get horizontal condylar guidance angle - Marking the Glenoid fossa (Superior curvature), Articular eminence (Inferior curvature) and the Frankfurt Horizontal Plane (FHP). The angle formed by joining the lines will be the horizontal condylar guidance angle, for that patient. See image.

Tracing of line AB joining height of superior curvature A and inferior curvature B, representing inclination of articular eminence. XY is parallel to FHP. C is angle made by intersection of mean curvature line and horizontal reference line.

Note that the articulator used is different from an actual patient. It is recommended to take the protrusive interocclusal record intraorally, rather than programming it on the articulator.

Ans. Yes sir, The protrusive interocclusal record will be taken intraorally.

Clarify the material of the wax indentations used to determine the values of condylar guidance with the Interocclusal record material at the try-in stage. Also, correct the sentence: "The articulator's lower member will be moved forward by about 6 mm after the try-in procedure, and it will then be closed in that position." The movement can only be done on the upper part of the articulators.

Ans. Bite registration aluminum wax will be used. Yes sir, The articulator’s upper member will be moved forward by about 6 mm after the try-in procedure, and it will then be closed in that position.

Please provide information on where the data for the sample size calculation came from.

Ans. The values for sample size is been taken from the following article-

Method: On OPG we should trace the following points to get horizontal condylar guidance angle - Marking the Glenoid fossa (Superior curvature), Articular eminence (Inferior curvature) and the Frankfurt Horizontal Plane (FHP). The angle formed by joining the lines will be the horizontal condylar guidance angle, for that patient. See image.

Tracing of line AB joining height of superior curvature A and inferior curvature B, representing inclination of articular eminence. XY is parallel to FHP. C is angle made by intersection of mean curvature line and horizontal reference line.

Note that the articulator used is different from an actual patient. It is recommended to take the protrusive interocclusal record intraorally, rather than programming it on the articulator.

Ans. Yes sir, The protrusive interocclusal record will be taken intraorally.

Clarify the material of the wax indentations used to determine the values of condylar guidance with the Interocclusal record material at the try-in stage. Also, correct the sentence: "The articulator's lower member will be moved forward by about 6 mm after the try-in procedure, and it will then be closed in that position." The movement can only be done on the upper part of the articulators.

Ans. Bite registration aluminum wax will be used. Yes sir, The articulator’s upper member will be moved forward by about 6 mm after the try-in procedure, and it will then be closed in that position.

Please provide information on where the data for the sample size calculation came from.

Ans. The values for sample size is been taken from the following article-
