Position and Mandibular Condyle Angulation in Class III Skeletal Malocclusion: A Lateral Radiography Analysis

Introduction

The temporomandibular joint (TMJ) is a complex structure that plays a crucial role in maintaining the normal function of the mandible. The TMJ is composed of the condyle, articular eminence, and glenoid fossa, and its proper alignment is essential for optimal jaw function. However, changes in the position and angulation of the condyle can be caused by skeletal malocclusion, a condition characterized by a change in the morphology or anatomy of the dentochraniofacial system. In this study, we aim to determine the average position and angulation of the mandibular condyle in individuals with class III skeletal malocclusion using lateral cephalometric radiography.

Methodology

This study employed a descriptive cross-sectional design, with a purposive sampling method used to select 50 lateral cephalometric radiographs from the medical records of patients with class III skeletal malocclusion who had never undergone orthodontic treatment at the PPDGs Ortodontic FKG USU clinic. The lateral cephalometric radiographic method was used to measure the position and angulation of the mandibular condyle.

Results

The results of this study indicate that the average co-TC distance value is 21.80 ± 3.71 mm, the distance of the vertical Co-T is 16.92 ± 3.34 mm, and the vertical co-T-T angle is 51.56 ± 6.75 °. These findings suggest that the mandibular condyle in patients with class III skeletal malocclusion is in an anterior position.

Discussion

The mandibular condyle position in the anterior position can indicate an imbalance in dentofacial relationships, which is often caused by the growth of asymmetrical bone or the presence of functional factors that contribute to malocclusion. Class III skeletal malocclusion is often associated with a mandibular protrusion or maxillary retrusion, both of which can cause an ideal condition. A good understanding of the position and angulation of the condyle is essential for designing effective orthodontic treatment plans.

The Role of Lateral Cephalometric Radiography in Orthodontic Diagnostics

Lateral cephalometric radiographic examination has an important role in orthodontic diagnostics, as it can provide a clear picture of the relationship between craniofacial structures. By using this technique, dentists can plan more precise orthodontic interventions based on the patient's structural conditions. In addition, a good understanding of the position and angulation of the condyle can also help in designing more effective care.

Implications for Treatment

In the case of class III skeletal malocclusion, a more directed orthodontic approach can be taken to improve the mandibular position and minimize complications that may arise due to abnormal condyle position. A better understanding of the factors that affect changes in the position of the condyle can also help in creating a more effective treatment strategy and more satisfying results for patients.

Conclusion

In conclusion, this study provides valuable insights into the position and angulation of the mandibular condyle in individuals with class III skeletal malocclusion. The findings of this study can help in designing more effective orthodontic treatment plans and improving the outcomes of patients with this condition. Further research is needed to continue to understand the factors that affect changes in the position of the condyle and to develop more effective treatment strategies.

Recommendations for Future Research

To increase understanding of skeletal class III malocclusion, it is essential for dental practitioners to continue to conduct research and analysis of the factors that affect changes in the position of the condyle. This can help in creating a better treatment strategy and more satisfying results for patients. Future studies should focus on investigating the relationship between the position and angulation of the condyle and the outcomes of orthodontic treatment.

Limitations of the Study

This study has several limitations, including the small sample size and the use of a single radiographic method. Future studies should aim to recruit a larger sample size and use multiple radiographic methods to increase the accuracy of the findings.

Future Directions

Future studies should aim to investigate the relationship between the position and angulation of the condyle and the outcomes of orthodontic treatment. This can help in creating a more effective treatment strategy and more satisfying results for patients. In addition, further research is needed to understand the factors that affect changes in the position of the condyle and to develop more effective treatment strategies.
