Clinical evaluation of osseointegrated prosthesis attached to natural teeth using semiprecision attachment

ABSTRACT

A more complex biomechanical situation is created when a fixed prosthesis is supported by fixture and natural teeth. The natural teeth more but an implant is osseointegrated. When an implant is attached to natural teeth, the movement of the teeth is transmitted to the implant. The prosthesis should be designed to reduce tooth movement, which is harmful to an implant. The use of Minicon semiprecision attachment allows a tooth to move downward. It also gives lateral stability to an implant prosthesis. In this study, six partially edentulous individuals were selected and a total of 22 root from titanium core-vent implants were inserted. The fixed bridge prostheses with Minicon attachment were evaluated clinically [including plaque index, gingival index, probing depth], and radiographically for marginal bone loss
