Summary
Attached gingiva width around dental implants does not appear to independently predict bone loss. Smoking is a significant factor in peri-implant bone stability, highlighting patient-related risks.
Area of Science:
- Dental Implantology
- Periodontology
- Biomaterials Science
Background:
- The role of keratinized mucosa in peri-implant health is debated.
- Limited evidence exists on the association between attached gingiva width and marginal bone loss around implants.
Purpose of the Study:
- To investigate the relationship between attached gingiva width and peri-implant marginal bone loss (MBL).
- To identify risk factors for peri-implant bone loss.
Main Methods:
- Retrospective evaluation of 330 dental implants in 107 patients over five years.
- Assessed MBL, plaque index, gingival index, probing depth, and attached gingiva width.
- Utilized multivariable generalized estimating equations (GEE) regression analysis.
Main Results:
- Attached gingiva width was not independently associated with MBL in multivariable analysis.
- Smoking was identified as a significant independent predictor of peri-implant bone loss.
- Univariate analysis showed greater MBL with less attached gingiva, but this was not significant after adjustment.
Conclusions:
- Attached gingiva width alone may not be an independent determinant of peri-implant bone loss.
- Patient-related factors, especially smoking, are crucial for peri-implant tissue stability.
- Further prospective studies are recommended to confirm findings.
