Summary
Immediate loading of single-tooth implants in the posterior jaw offers a viable treatment option. This approach demonstrated bone adaptation and positive tissue responses, achieving a satisfactory success rate.
Area of Science:
- Dental Implantology
- Prosthodontics
- Oral Surgery
Background:
- Immediate loading protocols for dental implants are increasingly explored.
- Posterior single-tooth replacement presents unique biomechanical challenges.
Purpose of the Study:
- To assess the clinical outcomes and safety of immediately loaded single-tooth implants.
- To evaluate implants placed in the posterior maxilla and mandible.
Main Methods:
- 20 adult patients received single-tooth implants in healed extraction sites.
- Temporary crowns were fitted, followed by definitive restorations after 6 weeks.
- Radiographic and clinical evaluations were performed up to 12 months.
Main Results:
- Marginal bone levels remained stable, with a mean change of 0.01 mm at 12 months.
- Positive peri-implant mucosal responses and esthetic outcomes were observed.
- One implant failure occurred due to cement impaction.
Conclusions:
- Immediate functional loading of posterior single-tooth implants is a viable treatment option.
- The study indicated bone adaptation to immediate loading.
- Satisfactory success rates and positive tissue responses were achieved.
