Evaluation of implant site preparation with piezosurgery versus conventional drills in terms of operation time, implant stability and bone density (randomized controlled clinical trial- split mouth design)

Abstract

Background The preparation of the implant bed has a major influence on the success rate and long-term survival of dental implants. Piezoelectric devices and special implant drilling inserts are now emerging to replace conventional drills showing improved bone response and healing around implants. The purpose of this study is to compare the piezoelectric inserts versus the traditional drills for implant site preparation. Methods Twelve male patients who received a total of twenty-four dental implants have been selected to participate in this split-mouth clinical trial. Each patient received two implants; one installed after piezosurgery assisted osteotomy, while the contralateral side received the implant with the original drilling protocol. The timing of surgery, implant stability, and bone density around the installed dental implants have been evaluated during a follow-up period extended to 4 months. Results a significant difference in terms of time of surgery (p < 0.005) and in implant stability at 4 months (p = 0.024) on the study side, while a non-statistical significance in terms of bone density was detected (p = 0.468). Conclusion The piezoelectric implant site drilling protocol seemed to be a reliable and repeatable technique. Despite the limited sample size and lengthier operative time, the piezoelectric inserts enhanced bone quality and implant stability.

Primary Stability of Implants Inserted into Polyurethane Blocks: Micro-CT and Analysis In Vitro

“…Furthermore, the movement of the TD is not constant. The creation of the implant site is a direct outcome of erosion, characterized by an elliptical pattern, leading to areas of bone deficiency [42]. The MM is not subject to this limitation.…”

Corrosion behavior of fiber laser welded Ti-6Al-4V alloy rods with different pH and temperature in 0.9 wt% NaCl medium

“…However, the maximum temperature that living tissue can withstand has been determined as 50 ˚C. In line with similar studies and information, the temperatures chosen to simulate both hot and cool oral environments were 25 and 50 ˚C [59,60]. To simulate acidic beverage environments, 0.9 wt% NaCl solutions at pH 3 and 5 were prepared using lemon juice.…”

Use of Piezosurgery in Implant Dentistry

“…A few histomorphometrical, immunohistochemical, and molecular analysis comparing piezosurgery with conventional drills and oscillating saws observed similar rate of bone healing but slightly more bone formation following piezosurgery. 46 Bone harvested using PS device was found to contain more osteoblast like cells. 47 Stubinger et al observed better periosteal microcirculation while using PS device for subperiosteal preparation which could be an incentive for enhanced bone metabolism.…”
