Randomized controlled clinical trial comparing implant sites augmented with a volume‐stable collagen matrix or an autogenous connective tissue graft: 3‐year data after insertion of reconstructions

Aim To assess mid‐term clinical, radiographic and profilometric outcomes at implant sites, previously grafted with a volume‐stable collagen matrix (VCMX) or an autogenous subepithelial connective tissue graft (SCTG). Methods VCMX or SCTG were randomly applied to single implant sites in 20 patients. Following abutment connection and insertion of final reconstructions (baseline), patients were re‐examined at 6 months (6M), at 1 year (FU‐1) and at...
