Summary
Student clinical techniques for posterior fixed bridges were evaluated. Differences in tooth inclination were noted between premolars and molars, impacting abutment preparation and crown data.
Area of Science:
- Dental Restorations
- Clinical Dentistry
- Biomechanical Analysis
Context:
- Evaluating student clinical proficiency in fixed prosthodontics.
- Assessing the accuracy of abutment preparation for posterior fixed bridges.
- Comparing clinical measurements of full-formed abutments and full-covered crowns.
Purpose:
- To analyze the clinical techniques of dental students by measuring side wall inclination of posterior bridge abutments.
- To compare full-formed abutment data with full-covered crown data.
- To identify significant differences in tooth inclination and their correlation with preparation parameters.
Summary:
- No significant differences in mesio-distal and bucco-lingual side wall inclination to the axis were found between upper and lower premolars or molars.
- Significant differences in inclination were observed between premolars and molars within the same jaw on both side walls.
- Premolars exhibited a closer rank correlation for margin and height diameters in the mesio-distal wall, while molars showed closer correlation in the bucco-lingual wall.
Impact:
- Highlights potential areas for improvement in dental student education regarding tooth preparation for fixed bridges.
- Provides data on the biomechanical considerations of abutment preparation influencing crown fit and longevity.
- Informs curriculum development to enhance precision in restorative dental procedures.
