A study designed as a randomized controlled trial of parallel group design will be conducted at the Dental clinic of the University of Valencia to evaluate the influence of 2.5 mm high abutments with different shapes (commercially available high abutments vs high abutments with modified shape to imitate short abutments) on peri-implant bone loss around bone level implants with platform switching in partially edentulous patients that require a fixed rehabilitation supported by two implants in the posterior mandible or maxilla and in fixed rehabilitation supported by one implant in the anterior mandible or maxilla (from premolar to premolar).
