Summary
Immediate tooth replacement with subepithelial connective tissue grafts (SCTG) shows high implant success and stable facial gingival levels. This technique, combined with proper implant positioning, yields favorable outcomes for peri-implant tissue response.
Area of Science:
- Dental Implantology
- Periodontology
- Oral Surgery
Background:
- Immediate tooth replacement offers aesthetic and functional advantages.
- Maintaining facial gingival stability and peri-implant tissue health are critical for successful outcomes.
- Subepithelial connective tissue grafts (SCTG) are utilized to augment soft tissues around implants.
Purpose of the Study:
- To evaluate the facial gingival stability after immediate tooth replacement with SCTG.
- To assess implant success rates and peri-implant tissue response in this context.
- To determine the long-term clinical and radiographic outcomes of this combined surgical approach.
Main Methods:
- A case series involving 10 patients undergoing immediate implant placement and provisionalization with SCTG.
- Clinical and radiographic evaluations were performed at multiple time points up to 12 months post-surgery.
- Statistical analysis included Friedman and Wilcoxon signed-ranks tests.
Main Results:
- 90% implant osseointegration rate at 1 year.
- Mean marginal bone loss of -0.31 mm and mean facial gingival level change of -0.05 mm at 1 year.
- Excellent papilla fill (>50%) observed in 89% of sites at 1 year, with good patient hygiene maintenance.
Conclusions:
- Immediate tooth replacement combined with SCTG demonstrates favorable implant success rates.
- Achieving proper 3D implant positioning and utilizing bone grafts are crucial for optimal results.
- This approach leads to stable facial gingival levels and positive peri-implant tissue response.
