PURPOSE. To determine whether there are clinical advantages to placing single dental implants 0.5 versus 1.5 mm subcrestally in healed bone crests. MATERIALS AND METHODS. Sixty partially edentulous patients requiring two single im-plant-supported crowns had both sites randomly allocated to either 0.5 mm or 1.5 mm subcrestal implant placement according to a split-mouth design at six centres; implant sites were left to heal for 3 months either submerged in aesthetic areas or not in non-a-esthetic areas. Provisional acrylic crowns were fitted and after 2 months replaced by definitive metal-ceramic crowns. Patients were followed up to 8 years after loading. Outcome measures were: crown or implant failures; complications; aesthetics, assessed using the pink esthetic score (PES); peri-implant marginal bone level changes; and patient preference, recorded by blinded assessors. RESULTS. Out of the 54 patients, 7 dropped out. There were no statistically significant differences between groups in ...

Abstract

PURPOSE. To determine whether there are clinical advantages to placing single dental implants 0.5 versus 1.5 mm subcrestally in healed bone crests. MATERIALS AND METHODS. Sixty partially edentulous patients requiring two single im-plant-supported crowns had both sites randomly allocated to either 0.5 mm or 1.5 mm subcrestal implant placement according to a split-mouth design at six centres; implant sites were left to heal for 3 months either submerged in aesthetic areas or not in non-a-esthetic areas. Provisional acrylic crowns were fitted and after 2 months replaced by definitive metal-ceramic crowns. Patients were followed up to 8 years after loading. Outcome measures were: crown or implant failures; complications; aesthetics, assessed using the pink esthetic score (PES); peri-implant marginal bone level changes; and patient preference, recorded by blinded assessors. RESULTS. Out of the 54 patients, 7 dropped out. There were no statistically significant differences between groups in ...
