Comparative evaluation of efficacy of Different decontamination methods on reuse Of implant healing abutments - an in vitro Study

Abstract

ABSTRACT The success of the dental implants mainly depends upon the osseointegration process which increases bone to implant contact. They are widely used for the treatment of partially and fully edentulous patients. After implant placement, there is loss of marginal bone due to surgical trauma. To reduce or to prevent further bone loss, special importance must be given to healing abutments. Contour and action of peri-implant tissue and its acknowledgement to enhance esthetics have been given importance since years. Healing abutments allows growth of gingival tissue and controls tissue shrinkage before final restoration of an implant. When it is made up of biocompatible material such as titanium or titanium alloys, it allows spread of soft tissue and its maturation during healing. It also protects internal part of the implant body from accumulation of debris during healing phase. So, a sterile environment is essential for dental implant placement. Scientific knowledge on the fundamental process of reuse of implant healing abutments is poor and therapy recommendations on peri-implantitis are mainly based on empirical values rather than on well-founded research results.
