Overview
This study was designed to assess peri-implant soft tissue health, volume and marginal stability at implants sites which presented small buccal bone dehiscences (<3mm evaluated in a vertical direction) at the time of insertion. Patients will be then randomly allocated to receive grafting with connective tissue graft or volume stable collagen matrix and evaluated at 3 months after surgery and at 12 months of follow up after crown placement.
Eligibility
Inclusion Criteria:
- Single tooth edentulous space
- Expected small buccal bone dehiscence (≤3mm evaluated in a vertical direction) assessed according to the prosthetically guided position of an implant of 4 mm in diameter planned using the pre-surgical CBCT
- Completed non-surgical periodontal therapy (if needed)
- FMPS and FMBS < 20%
Exclusion Criteria:
- Age < 18 years old
- Pregnancy or lactation
- Heavy smokers (> 10 cigarette/day)
- Conditions or diseases contraindicating surgical interventions
- Absence of the expected small buccal bone dehiscence (≤3mm evaluated in a vertical direction) verified after implant placement
- Need for bone regeneration at the implant site
