Summary
Immediate implant placement in the esthetic zone is challenging. Using deproteinized bovine bone mineral (DBBM) and acellular dermal matrix (ADM) during immediate implant placement resulted in minimal ridge width alteration after 3 months.
Area of Science:
- Dental Implantology
- Periodontology
- Oral Surgery
Background:
- Immediate implant placement in esthetic zones poses challenges due to potential ridge width reduction and gingival asymmetry.
- Maintaining ridge width is crucial for favorable esthetic outcomes after dental implant procedures.
Observation:
- A case series involving 19 immediate implants placed in maxillary second bicuspid sites with intact facial plates.
- Implants were positioned palatally, creating a ≥2 mm gap grafted with deproteinized bovine bone mineral (DBBM).
- Acellular dermal matrix (ADM) was used for facial grafting; healing abutments were placed for 3 months.
Findings:
- Post-healing measurements showed minimal ridge width alteration: a 0.1 mm reduction at 2 mm and a 0.5 mm increase at 5 mm from the gingival margin.
- All implants achieved successful osseointegration without complications.
- Patient biotype did not significantly influence the observed outcomes.
Implications:
- The combined use of DBBM and ADM during immediate implant placement effectively preserves ridge width.
- This technique offers a predictable solution to prevent gingival asymmetry, enhancing esthetic results in challenging implant cases.
- Further research can explore long-term stability and applicability across different defect types.
