An abutment is a dental implant that provides support and retention for a fixed or removable dental prosthesis. The interocclusal distance, position of the implants, gingival height, biomechanical factors, the patient’s psychological status, expectations and economic conditions are essential in the choice of abutment. In addition to the aforementioned factors, the number of implants and their crestal distribution, the shape of the alveolar crest (triangular, ovoid or square) and the amount of crestal resorption must also be taken into consideration. The selection of the optimal abutment for an implant-supported fixed prosthesis is one of the most pivotal decisions in the field of dentistry.
