Ultrasonic vs Drill Implant Site Preparation: Post-Operative Pain Measurement Through VAS, Swelling and Crestal Bone Remodeling: A Randomized Clinical Study

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.

Environmental Disinfection of a Dental Clinic during the Covid-19 Pandemic: A Narrative Insight

“…Ventilation can reduce virus concentration in the air, limiting airborne transmission, but also the settling of viral particles, causing fomite transmission, for example, in influenza viruses [ 71 ]. The use of high ventilation rates during and after aerosol-generating procedures, such as high-speed drills, or piezosurgery [ 72 – 75 ] or between two patients has the potential to efficiently reduce circulating concentration of viral particles.…”

“…So, the thermal cycle, although increasing the oxygen content, did not affect the cutting ability of the drills. Steel drills are considered as suitable materials in dental implant bed preparation for oral rehabilitation; however, many biologic and physical events occur after osteotomy preparation [43]. One of the major reasons for these is the release of microparticles of steel, which threaten and induce reaction in bone or soft tissues.…”

Zirconia crowns cemented on titanium bars using CAD/CAM: a five-year follow-up prospective clinical study of 9 patients

“…The success of an implant surgery depends on the bone and soft tissue healing after the process of implant site preparation [2,21]. During healing and function of a prothesis the bacterial adhesion is very important for a high success of an implant [22].…”

“…The long-term predictability of the restoration involves several aspects concerning the implant surface [1], surgical techniques [2,3] and the anchorages used. Screwretained prosthesis, cemented, or a combined approach have been proposed as prosthetic connections between the implant and the restoration.…”
