Abstract
Background: Piezosurgery is a surgical procedure that is able to perform osteotomies by a micrometric and selective cut of the bone tissue. The objective of this investigation was to evaluate two different techniques; an ultrasonic device, and a drill approach for implant site preparation. Methods: A total of fifty patients were recruited for the randomized clinical trial to receive dental implants for fixed prosthetic restoration in the posterior mandible and were allotted to two groups. In Group A the implant site was prepared following a drilling technique, while in Group B the implant site was prepared using an ultrasonic device; moreover, the operative duration was recorded. Postoperative pain and swelling were evaluated at 1, 2, 4, and 6 days. The crestal bone resorption was measured at 3 months from implant placement by a three-dimensional tomography evaluation. Results: The findings suggest that osteotomies performed by an ultrasonic device cause less pain and swelling. On the other hand, the piezoelectric preparation was characterized by a significative increase in the operative time. No statistical differences in crestal bone resorption were evident in the two different approaches. Conclusions: According to the outcome of the study, ultrasonic implant bed preparation can be used with success in implantology and could be considered a suitable alternative to traditional drilling techniques for dental fixture placement.
Highlights
Nowadays, osseointegrated implants have very high clinical long-term predictability [1,2,3,4], and in recent years there has been great changes regarding their surface properties
The aim of the present investigation was to study the post-operative pain of surgery and implants positioned in sites prepared with two different techniques: using conventional drills and an ultrasonic approach
The investigators hypothesized that implant bed preparation with ultrasonic tips may offer good clinical results with reduced swelling and pain
Summary
Nowadays, osseointegrated implants have very high clinical long-term predictability [1,2,3,4], and in recent years there has been great changes regarding their surface properties. It has been demonstrated that the features of the fixture surface in terms of nano, micro topography, and physicochemical properties are key factors in achieving dental implant. The achievement of primary stability of the fixture, bone tissue density and quality, the implant micro-design, surface properties, are all necessary factors in the successful osseointegration of dental implants during surgical procedures [9,10]. Piezosurgery is a surgical procedure that is able to perform osteotomies by a micrometric and selective cut of the bone tissue. The objective of this investigation was to evaluate two different techniques; an ultrasonic device, and a drill approach for implant site preparation
