This proposal suggests the use of a collagen scaffold as a core material for GBR in the case of a missing tooth between two existing teeth, in situations where there is sufficient bone to place an implant but a horizontal defect is present in the ridge. The tested question is whether a thick, reinforced, resorbable collagen scaffold can provide a stable basis for restoring the lost volume of a deficient ridge. As a secondary aim, a positive result could present an option to replace the connective tissue interpositional graft procedure.
