Clinical and Radiographic Comparison between Piezoelectric Implant Osteotomy Preparation versus Conventional Drilling Technique

Piezo-surgery was introduced for implant site preparation due to its atraumaticcapabilities in preparation of the recipient bed thus offering improvedosseointegration and better bone healing. OBJECTIVE: to evaluate the effectof using piezoelectric bone surgery for implant osteotomy preparation onimplant stability and osteointegration compared with conventional drillingtechniques. METHODS: 16 implants equally installed in the maxillary anterioror premolar regions of adult patients, divided into two groups: Group I where theimplant osteotomy site was performed using conventional drills. Group II wherethe implant osteotomy site was performed using specific piezoelectric inserts.All implants were clinically evaluated for implant stability using OSTELLdevice immediately after implant placement and 6 months postoperatively, aswell as radiographically by digital parallel periapical tecgnique immediatelypost-opertively, then after three and six months to assess changes in relativebone density using digora software. RESULTS: Both groups showed asignificant increase in implant stability values (ostell readings) throughout thestudy period. Piezoelectric osteotomy group showed statistically higher Ostellvalues after six months in comparison to the conventional drilling group.Radiographic evaluation showed that relative bone density values increased forboth groups at the apex, mesial and distal implant aspects throughout the studyperiod, with the highest density values at the six months period. Comparison indensity values between both groups showed statistically higher bone densityvalues in the piezoelectric osateotomy group after six months. Correlationbetween clinical implant stability values (Ostell readings) and radiographicbone density values showed a significant positive correlation at the six monthsfollow-up period. CONCLUSIONS: Osseointegration is improvedsurrounding implants inserted in bone when Piezoelectric drilling is used fordrilling of osteotomy sites in the anterior maxillary region can be a successfuloption for increasing implant stability values throughout the healing period incomparison to conventional drilling techniques.
