Buccal bone resorption around posterior implants after surgery: a 1-year prospective study
Summary
Buccal bone around dental implants resorbed horizontally and vertically one year after surgery. Initial bone thickness influenced bone retention, but mucosal recession was not directly linked to bone loss.
Area of Science:
- Dental Implantology
- Periodontology
- Oral Surgery
Background:
- Single-stage implants are common in posterior regions.
- Understanding peri-implant tissue changes is crucial for long-term implant success.
Purpose of the Study:
- To evaluate dimensional changes in buccal bone and mucosa around single-stage implants in the posterior jaw.
- To assess bone resorption and mucosal recession at 6 months and 1 year post-surgery.
Main Methods:
- Prospective study of 66 implants in 30 patients.
- Measurements of buccal bone and mucosa dimensions at baseline, 6 months, and 1 year.
- Radiographic assessment of bone resorption and plaster cast analysis of mucosal recession.
Main Results:
- Buccal bone showed horizontal resorption throughout the study period.
- Vertical resorption of buccal marginal bone was approximately 1 mm between 6 months and 1 year.
- Initial bone thickness correlated with bone retention at 1 year; mucosal thickness showed minimal change.
Conclusions:
- Buccal bone undergoes both horizontal and vertical resorption post-implant surgery.
- The initial bone contour is a significant factor in predicting bone retention.
- Buccal bone resorption did not directly correlate with mucosal recession.
