Poor occlusal patterns, plaque, and cemented restorations significantly increase marginal bone loss (MBL) around dental implants. Maintaining good oral hygiene and proper occlusal guidance is crucial for long-term implant success.
Area of Science:
- Dental Implantology
- Periodontology
- Prosthodontics
Background:
- Dental implants are a common solution for tooth replacement.
- Marginal bone loss (MBL) is a key indicator of implant health.
- Understanding factors influencing MBL is vital for long-term implant survival.
Purpose of the Study:
- To retrospectively evaluate associations between occlusal, periodontal, and implant-prosthetic parameters and marginal bone loss (MBL).
- To determine factors affecting implant survival rates after prosthetic loading.
Main Methods:
- Retrospective evaluation of 164 external hexagon implants in 82 patients.
- Analysis of MBL from radiographs at baseline and follow-up (5.7 ±3.2 years).
- Assessment of occlusal, periodontal, and prosthetic parameters using Cox regression analysis.
Main Results:
- Implant survival rate was 98.8%.
- MBL was significantly associated with non-working side contacts, inadequate anterior guidance, lateral group guidance, peri-implant plaque index, prosthetic design, and retention.
- Inadequate occlusal patterns, visible plaque, cemented, and splinted restorations correlated with increased MBL.
Conclusions:
- Occlusal factors, plaque presence, and prosthetic design (cemented/splinted restorations) are critical determinants of MBL around implants.
- These findings highlight the importance of meticulous occlusal management and hygiene for preserving peri-implant bone levels.
- Optimizing occlusal schemes and prosthetic choices can enhance long-term dental implant success.
