Three-Year Analysis of Tapered Screw-Vent Implants Placed into Extraction Sockets Grafted With Mineralized Bone Allograft
With clinicians placing more dental implants, it is becoming increasingly important to maintain bone volume after tooth extraction. This article reports the results of implants placed into extraction sites grafted with particulate mineralized bone allograft (Puros). A total of 313 extraction sites were grafted with mineralized bone graft during a 36-month period. A total of 252 Tapered Screw-Vent dental implants were placed into the grafted extraction sites after a 4- to 7-month healing period. All reentries revealed a bony hard structure acceptable for osteotomy preparation. A total of 244 of these implants have been restored with fixed prosthesis and 6 with removable overdentures for a total of 250 loaded implants. A total of 6 implants failed, which required their removal (2 implants before load and 4 after loading), resulting in a 97.6% implant success rate. We conclude that mineralized human allograft placed into extraction sites is clinically useful to maintain bone volume. This material provided a bony hard structure acceptable for implant placement with good success rates.Abstract
