Mechanical/technical complications associated with implant treatment and its countermeasure

Abstract

Biological and mechanical/technical complications associated with implant treatment have frequently been reported. Countermeasures are undertaken to overcome these mechanical/technical complications by improving the products and developing new materials. In this paper, complications observed after prosthesis have been studied, as to their causes and measures to be taken; (1) fracture or loosening of abutment screws, (2) cleanability of dental implant superstructure, (3) esthetic issues, (4) loss of proximal contacts, (5) fracture of zirconia abutments, and (6) fracture or chipping of veneering ceramic and monolithic zirconia superstructure.
