Research summary
Dental implants and post-operative pain management


Associate Professor Kumara De Silva has special interest in exploring the avenues to find ways of rehabilitating partial and complete edentulous patients with economical use of dental implants.The focus is to look for ways of rehabilitating patients in the shortest possible time following dental extractions using the minimum number of implant fixtures. His research expands further into analysing the quality of life of individuals treated with dental implants and to find the feasibility of using metal-free implant fixtures.This area of research was accepted as an area of research strength by the University of Otago.

He also conducts research also conducts research in the management of post- operative pain after surgical removal of wisdom teeth and to evaluate the metabolism of commonly used analgesics in the body. Several double-blinded crossover trials were conducted to compare different analgesics commonly used in the management of post-operative pain after surgical removal of wisdom teeth. In addition, he has designed a new flap technique for removal of wisdom teeth to minimise post-operative complications.
