Summary
Replacing single missing posterior teeth with implant-supported prostheses is effective. While survival rates are similar for immediate and delayed implant placement, delayed protocols show slightly higher success rates.
Area of Science:
- Dental Implantology
- Prosthodontics
- Oral Surgery
Background:
- Single missing teeth in the posterior maxilla and/or mandible present a restorative challenge.
- Implant-supported prostheses are a common solution for replacing missing teeth.
Purpose of the Study:
- To evaluate the efficacy of single-tooth implant prostheses in posterior quadrants.
- To compare immediate versus delayed implant placement outcomes.
Main Methods:
- Systematic literature search of Medline (PubMed), Ovid Medline, and CENTRAL (1985-2014).
- Inclusion of 36 articles from 141 reviewed publications.
- Analysis of survival rates, success rates, and bone loss.
Main Results:
- Immediate implant placement: 96.9% survival, 100% success, 0.85 mm bone loss.
- Delayed implant placement: 96.8% survival, 94.1% success, 0.55 mm bone loss.
- Comparison: Survival rates similar (96.8% vs 96.3%), success rates higher for delayed (85.8% vs 93.3%).
Conclusions:
- Single molar implants are a viable treatment for posterior tooth replacement.
- No significant difference in survival rates between immediate and delayed implant placement.
- Delayed loading protocols demonstrated slightly higher success rates.
