Summary
Single immediate implants demonstrate high survival rates and minimal bone loss over five years. However, aesthetic complications like mid-facial recession increased, suggesting this technique may not be suitable for routine use.
Area of Science:
- Dentistry
- Oral Implantology
- Aesthetic Dentistry
Background:
- Limited long-term data exists for soft tissue aesthetics following immediate implant placement.
- This study aimed to assess the 5-year clinical and aesthetic outcomes of single immediate implants in the aesthetic zone.
Observation:
- Twenty-two patients with specific aesthetic risk factors received immediate implants with flapless surgery and bone grafting.
- Follow-up at 5 years included 17 patients, with some requiring connective tissue grafts (CTG) for early complications.
Findings:
- High implant survival and stable marginal bone levels were observed over 5 years.
- Mid-facial recession and alveolar process deficiency worsened after the first year, with 8/17 implants showing aesthetic complications.
- Implants in lateral incisor positions maintained stable soft tissue levels, unlike those in central incisor positions.
Implications:
- While implant survival is high, the deterioration of soft tissue aesthetics and contour necessitates caution.
- The aesthetic complication rate suggests that immediate implant placement (Type I) may not be advisable for general dental practice.
- Further research into optimizing soft tissue management for immediate implants is warranted.
