Abstract

Background: The mandible is the most durable and only movable bone that constitutes the lower one-third of the face.The mandibular condyle and coronoid processes are two anatomical structures located in the superior portion of the ramus of the mandible. Morphometric understanding of these structures is key to the diagnosis of various disorders associated with the temporomandibular region. It also aids in devising a plan for the management of such disorders.
Purpose: The purpose of this study is to evaluate the anatomical corelation between the condyle and coronoid of the mandible.
Materials and Methods: This retrospective study was conducted by obtaining 100 high-resolution computed tomography images from departmental archived records between 2018 and 2024. After acquisition, these images were incorporated into MIMICS Materialize software to create stereolithography models, and morphometric analysis was carried out.
Results: Out of 100 HRCT data obtained, 87 were male and 13 were female. There is a statistically significant difference in length and angulation of the coronoid and condyle on both sides. The condyle length for males was (4 ± 5.5 mm) higher than the condyle length of females on both sides. However, the coronoid length of males and females varies in a range of 0.5-2mm on both sides of the mandible.
Conclusion: Understanding the morphological variation of mandibular condylar and coronoid processes aids in various fields of medicine like forensics, anthropology, and reconstructive maxillofacial surgery. Our study inference will aid surgeons in planning coronoid grafts for condylar reconstruction as well as other maxillofacial reconstructions. Additionally, it helps in forensic odontology to determine a person's age and gender.
