Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Subepithelial Connective Tissue Graft (SCTG)

Soft tissue augmentation at peri-implant small buccal dehiscence with subepithelial connective tissue graft harvested from the patient's palate

Group Type ACTIVE_COMPARATOR

Soft tissue augmentation with subepithelial connective tissue graft (SCTG)

Intervention Type PROCEDURE

After the assessment of the vestibular bone dehiscence at implant site from the most apical extension of the trans-mucosal implant collar (≤3 mm evaluated in a vertical direction), SCTG will be harvested from the palate and sutured to the flap. Simple interdental sutures will be performed in order to stabilize the flap in close contact with the healing screw.

Volume Stable Collagen Matrix (VCMX)

Soft tissue augmentation at peri-implant small buccal dehiscence with xenogenic volume stable collagen matrix

Group Type EXPERIMENTAL

Soft tissue augmentation with xenogenic volume stable collagen matrix (VCXM)

Intervention Type PROCEDURE

After the assessment of the vestibular bone dehiscence at implant site from the most apical extension of the trans-mucosal implant collar (≤3 mm evaluated in a vertical direction), VCMX will be sutured to the flap and simple interdental sutures will be performed in order to stabilize the flap in close contact with the healing screw.
