Summary
Immediate functional loading of dental implants for single-tooth replacement shows comparable long-term results to conventional methods. This approach, particularly with conventional installation, is a viable option for esthetic areas.
Area of Science:
- Dental Implantology
- Prosthodontics
- Oral Surgery
Background:
- Limited long-term studies compare immediate vs. conventional loading for single-tooth implants.
- Immediate functional loading (IFL) offers potential esthetic and functional benefits.
Purpose of the Study:
- To prospectively evaluate the 5-year clinical and radiological outcomes of IFL implants in single-tooth replacement.
- Compare IFL with conventional submerged implant placement and loading.
Main Methods:
- 151 subjects received single-tooth implants (positions 15-25, 35-45) in a randomized controlled trial.
- Groups: Conventional (control), IFL with conventional drilling (test 1), IFL with osteotome technique (test 2).
- 5-year follow-up included clinical/radiographic exams and complication recording.
Main Results:
- Four implants were lost in IFL groups within the first year; no further losses occurred up to 5 years.
- No significant differences in marginal bone level changes between groups.
- 52% of implants showed bone gain, 28% bone loss between years 1 and 5; 5.7% experienced biological complications.
Conclusions:
- Immediate functional loading with conventional implant installation is a valid long-term treatment alternative for single-tooth replacement.
- IFL protocols demonstrate promising clinical and radiological stability over 5 years.
- The osteotome technique in IFL showed slightly higher early implant loss.
