Stress and strain patterns of 1-piece and 2-piece implant systems in bone: a 3-dimensional finite element analysis.

abstract：PURPOSE:To compare hard- and soft-tissue changes around immediate implants connected with 2 types of healing abutments during the early phases of healing. MATERIALS AND METHODS:Twenty-eight immediate implants were placed into molar/premolar sockets through a modified osteotomy method. The gaps around implants were gra...
