Immediate Implants Placed in Infected and Noninfected Sites after Atraumatic Tooth Extraction and Placement with Ultrasonic Bone Surgery

摘要: Background Only a few reports deal with implants placed in infected postextraction sites. Purpose Survival rates of cohort immediate cases acute and chronically sites were compared noninfected ones while (1) tooth extraction osteotomy prepared piezosurgery device (2) ultrasonication was applied to abate the bacterial charge at sites. Materials Methods Eighty-six patients received 168 distributed into three groups: (85), (36), (47) sites. Atraumatic implant performed an ultrasonic surgery without flap elevation. All same medication surgical protocol; ultrasonicated during 30 seconds 72 W. Kaplan–Meyer survival calculated 1 year. Results The 1-year noninfected, chronically, groups 98.8, 100, 94.4%, respectively. The differences not statistically significant. No lost after loading. teeth roots could be extracted one piece. Drilling sockets uncomplicated, skidding. Conclusions Implant might similar when receive standard medical treatment are ultrasonicated. tooth/root placement can reliably piezoelectric surgery.
