Minimally invasive piezosurgery for a safe placement of blade dental implants in jaws with severe bone loss

Abstract

Aim Severe atrophies of edentulous jaws require major reconstructive bone surgery in order to allow the placement of root-form implants with standard diameter. These bone augmentation techniques represent the best option reported in the literature, but they are often rejected by patients because of their high economic and biological costs in addition to the possibility of failure in the short and/or long term. In the maxilla regenerative methods (onlay, inlay, and distraction) have high success rates, whereas in the mandible, especially in the distal atrophic area, they are not so predictable. In such situations an alternative technique for fixed prosthethic rebilitation is the insertion of platform blade implants, which have their elective indication for atrophic bone ridges with reduced width, owing to their reduced thickness. The aim of this study is to assess the effectiveness of the use of piezoelectric ultrasonic handpieces, in order to simplify the placement of blade implants, making it safer and less traumatic than with conventional surgical procedures. Materials and methods Platform blade implants are extension implant functionally and aesthetically reliable, even if they require a more difficult surgical technique compared with the one currently in use for screw implants. A minimally invasive procedure by means of piezosurgery that was performed on 142 subjects is presented and a case is reported which highlights the successful results. Results and conclusion The use of piezoelectric ultrasonic handpieces simplifies the surgical procedure for the placement of blade implant, making it safer and less traumatic.
