Summary
Facial alveolar bone is often thin, increasing implant failure risk. Bone augmentation is frequently necessary for esthetic dental implant success, especially in anterior regions.
Area of Science:
- Dental Implantology
- Oral and Maxillofacial Radiology
- Periodontology
Background:
- Facial alveolar bone width is critical for dental implant success.
- A 2 mm bone wall thickness is recommended to prevent bone loss.
- Immediate implant placement requires adequate bone support.
Purpose of the Study:
- To measure facial alveolar bone wall width using CBCT.
- To evaluate bone dimensions in an Asian population.
- To identify factors influencing bone width.
Main Methods:
- Retrospective analysis of 200 Asian CBCT scans.
- Measurements taken at 1, 3, and 5 mm apical to the alveolar crest.
- Analysis included descriptive statistics and frequency analysis.
Main Results:
- Facial bone wall width averaged 0.9 mm in anterior regions, increasing posteriorly.
- A width of 2 mm was rarely achieved, particularly in anterior teeth.
- Bone dehiscence was common, ranging from 9.9% to 53.6%.
Conclusions:
- The facial alveolar bone wall is typically thin in both jaws.
- Bone augmentation is often required for esthetic implant placement.
- Patients may need additional procedures for optimal implant outcomes.
