Summary
Biologically guided crown design significantly enhances peri-implant soft tissue volume around convergent collar implants. This technique promotes soft tissue stability and volume increase over two years.
Area of Science:
- Dental Implantology
- Periodontology
- Prosthodontics
Background:
- Evaluation of soft tissue thickness around convergent collar implants and shoulderless abutments.
- Utilized intraoral scanner (3Shape, TRIOS®) for precise measurements.
Purpose of the Study:
- To assess the impact of biologically guided crown design on peri-implant soft tissue volume.
- To analyze soft tissue changes around convergent implants over a two-year period.
Main Methods:
- Ambispective longitudinal analytical study.
- 26 implants in 17 patients, divided into Prama Implants (Group 1) and Shelta implants with XA abutment (Group 2).
- One- and two-year follow-up thickness measurements using an intraoral scanner.
Main Results:
- Group 1 showed an increase in mean thickness from 6.53 mm to 8.06 mm.
- Group 2 showed an increase in mean thickness from 7.66 mm to 8.42 mm.
- Both groups demonstrated significant soft tissue increase.
Conclusions:
- Biologically guided crown design appears to significantly augment soft tissue volume around convergent implants.
- This approach may enhance soft tissue stability and esthetic outcomes.
- Key terms: Biologic width, peri-implant soft tissue, BOPT, soft tissue stability.
