Summary
Dental implants with either a fully rough surface (FR) or a partially machined surface (PR) showed similar clinical performance after sinus-lift surgery. Both implant types are viable options for augmenting the sinus bone.
Area of Science:
- Dental Implantology
- Oral Surgery
- Periodontology
Background:
- Sinus-lift procedures are common for dental implant placement in atrophic maxillae.
- Implant surface characteristics may influence outcomes in augmented bone.
Purpose of the Study:
- To compare the clinical performance of fully rough (FR) implants versus partially rough (PR) implants in conjunction with sinus-lift procedures.
Main Methods:
- A randomized controlled trial involving 26 patients undergoing staged sinus-lift augmentation.
- FR implants were compared to PR implants in separate patient groups.
- Clinical parameters (plaque, BOP, PPD, REC) and radiographic bone levels were assessed over one year.
Main Results:
- The cumulative survival rate was 82.9% with no significant difference between FR and PR implant groups.
- Implant type, residual crest height, osseointegration time, loading time, and smoking did not impact survival.
Conclusions:
- Fully rough (FR) and partially rough (PR) dental implants demonstrate comparable clinical performance when placed in augmented sinuses.
- Both implant surface designs are suitable for use following sinus-lift augmentation.
