Master’s Degree Awarded to Ms. Ibtisam Al-Ezzi

Ms. Ibtisam Khaled Mohammed Al-Ezzi was awarded a Master’s Degree for her thesis titled: ‎ Three-Dimensional Assessment of Condylar Volume in Skeletal Class I with Vertical Skeletal Patterns in Yemeni Adults, which was submitted to the Department of Orthodontics, Faculty of Dentistry – Sana’a University. The MA defense was held on Wednesday, February 11, 2026.

The MA Viva-voce Committee, which was formed based on a resolution issued by the Graduate Studies and Scientific Research Council, consisted of the following:

The thesis aimed to:
 Conduct a three-dimensional assessment and comparison of condylar volume in ‎Skeletal Class I individuals with different vertical skeletal patterns among Yemeni ‎adults.‎
The study yielded a number of key findings summarized as follows:
 The vertical skeletal pattern is the primary factor influencing condylar morphology.‎
 Significant variations were observed in condylar volume, length, and height.‎
 No statistically significant differences were found with respect to gender or side.
In light of these findings, the researcher recommended the following:
 Utilizing volumetric analysis based on Cone Beam Computed Tomography (CBCT), particularly for patients with increased vertical jaw divergence, due to their relatively smaller condylar mass and potentially reduced adaptive capacity. Careful monitoring is advised during orthodontic and surgical interventions to avoid excessive loading on the temporomandibular joint (TMJ).
 Encouraging future longitudinal studies to investigate volumetric changes of the mandibular condyle in Skeletal Class II and III malocclusions, as well as examining the long-term effects of different orthodontic treatment modalities on condylar remodeling within the Yemeni population.
 Adopting the normative values identified in this study as diagnostic references specific to the Yemeni population, thereby reducing reliance on international standards that may not accurately reflect local craniofacial characteristics.
The defense session was attended by a number of professors, researchers, students, colleagues, and the researcher’s family.
