Master’s Degree Awarded to Mr. Badr Hassan Mohammed Qaed in Orthodontics
Mr. Badr Hassan Mohammed Qaed was awarded a Master’s Degree in Orthodontics for his thesis titled: Three-Dimensional Evaluation of Transverse Basal Arch Measurement and Molar Inclination in Yemeni Adults, which was submitted to the Faculty of Dentistry – Sana’a University. The MA defense was held on Tuesday, November 25, 2025.
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:
| # | Committee Members | Designation | Position |
| 1 | Prof. Ghamdan Abdullah Ahmed Al-Harazi | Internal Examiner | Chair |
| 2 | Prof. Naila Mohammed Ali Al-Mujahid | Main Supervisor | Member |
| 3 | Assoc. Prof. Khaled Ahmed Ali Al-Dharee | External Examiner | Member |
The study aimed to:
- Evaluate the transverse dimensions of the maxillary and mandibular basal arches using three-dimensional techniques.
- Analyze molar inclination and angulation in Yemeni adults and examine their impact on the diagnosis of jaw discrepancies and orthodontic treatment planning.
The study employed three-dimensional imaging and digital scanning techniques to measure basal arch width and molar inclination. It adopted a rigorous methodology for sample collection, measurement procedures, and statistical data analysis. It focused on highlighting the clinical value of three-dimensional measurements in orthodontic diagnosis and precise treatment planning.
The study yielded a number of key findings summarized as follows:
- Three-dimensional techniques demonstrated high accuracy in assessing transverse jaw dimensions compared with conventional methods.
- Measurable differences were identified, reflecting distinct morphological characteristics in the adult Yemeni sample.
- The findings can be utilized to improve the diagnosis and treatment of basal arch discrepancies and molar inclination.
In light of these findings, the researcher recommended:
- Adopting local reference standards that reflect the specific characteristics of the Yemeni population in jaw measurements.
- Expanding future research to include larger samples from different governorates.
- Emphasizing the importance of training dental professionals in advanced imaging and digital scanning technologies to ensure diagnostic accuracy and high-quality treatment planning.
The defense session was attended by a number of academics, researchers, dental students, and specialists in orthodontics, as well as the researcher’s colleagues.
