Clinical and Laboratory Survey Regarding Modern Tooth- Supported Fixed Partial and Implant-Supported Prosthetics in Sana’a City.

Background and aims: The study assessed the success rates of correct work performed by dentists and their collaboration with technicians in implant-supported prosthetic treatments. It analyzed preferred techniques, treatment plans, and materials used in fixed prosthetics and implants, while also identifying daily clinical challenges. Ultimately, the aim was to understand, apply, and keep pace with technological advancements in restorative dentistry.

Methods: The study is a cross-sectional study in Sana'a, Yemen, using an online self-designed questionnaire. The questionnaire was developed using Google Forms and reviewed by experts from the Prosthetics department at Sana'a University to ensure content validity and accuracy. The questionnaires were designed using previous studies and reference books for fixed prosthodontics. They have five primary axes, each focusing on different research goals.

Results: The study surveyed 101 dentists in Sana'a, Yemen, revealing a gender distribution of 61.4% males and 38.6% females, with varying academic qualifications: 24.8% bachelor's, 43.6% master's, and 31.7% doctorate. Experience levels included 36.6% with 1–5 years, 25.7% with 5–10 years, and 37.7% with over 10 years. Implant procedures showed that 48 dentists performed fewer than 10, 20 performed 10-20, and 32 performed over 20. Panoramic radiographs were always used by 57.5%, while alginate impressions were used consistently by 35%. The usage of diagnostic waxup included 11.9% always, 45.6% sometimes, and 5.9% never; digital images were used always by 12.9% and never by 9.9%. Smile design and digital color matching were less frequently adopted. A significant association was found between male dentists and those performing over 20 implants (OR 5.5, p=0.001), while female dentists had a negative correlation. Dentists with a doctorate had an odds ratio of 7.9 for more than 20 implants (p < 0.0001), contrasting with those holding a bachelor's degree showing a negative association (p = 0.0006). Additionally, dentists with over 10 years' experience had an odds ratio of 9.2 for performing more than 20 implants (p < 0.0001), while less experienced dentists showed significant negative correlations.

Conclusions: Based on study data, 49.5% of the surveyed dentists do not practice implant-supported restorations, despite a high percentage of practitioners having similar levels of academic qualifications (bachelor’s, master’s, or doctorate) and comparable experience.
