INFLUENCE OF ABUTMENT DESIGN ON THE SUCCESS OF DENTAL IMPLANTS

Abutment angulation is one of the numerous biomechanical variables involved in implant dentistry that need scientific evaluation [Saab, 2007]. The aim of the present study was to investigate experimentally and numerically the influence of a fine threadedagainst a roughenedcervical region of immediately loaded dental implants in combination with straight and 20°angled abutments on the implant primary stability followed by a clinical validation of the results in a one year follow up study for immediately loaded and osseointegrated cases.
