CAD/CAM technology in implant abutment design

Study of implants has become indispensable and so is the biomechanics related to dental implant therapy. Implant therapy is a fast-growing and brightest prospect in the rehabilitation of completely and partially edentulous arches. The evolution of implants has become a ‘restorative driven ’field, and it is therefore important to know the designing principles of abutments and its connection to the implants and its rationale for use in clinical practice. The key is to have an optimum selection and designing of the implant to meet the implant position and angulations in the clinical scenario. Implant abutment connection is a crucial synapse between the implant and the abutment. It is an important determinant of the strength and stability of an implant supported restoration and plays a major role in the success of the implant. This article highlights designing principles of various abutments and its role in aesthetics and the application of computer-aided design and computer-aided manufacturing to produce implant abutment.
