Abstract
Aim: the aim of this study is to demonstrate the effect of immediate implant placement with immediate loading combined with GBR using a mix of autogenous bone and xenograft with a collagen membrane in type 2 extraction sockets on amount and level of labial Plate of bone reconstruction, primary stability and PES after 6 months post-operative
Methodology: a total of 10 patients with type 2 extraction sockets ,underwent a traumatic extraction of their teeth in maxillary esthetic zone from right second premolar to left second premolar, and received immediate implant placement with guided bone regeneration that achieved by harvesting autogenous bone from chin and mixed with xenograft and placement of a collagen membrane inside the socket without flap elevation , the graft and membrane were fixed by a provisional restoration that screw-retained on the implant. Outcome measures were: amount of graft remodeling primary stability and PES 6 months post-operative.
Results: mean bone level immediately post- operative was 3.33+0.68 that decreased to 2.87+0.62mm 6 months later the difference was statistically significant(p < 0.001) ,mean PES immediately postoperative was 9.85+1.07 that increased to 12.85+0.80 six months postoperative the difference was statistically significant(p < 0.001) , mean stability immediately postoperative was 65.6+3.2 that increased to 73.7+2.4 six months postoperative the difference was statistically significant(p < 0.001)
Conclusion: guided bone regeneration with immediate implantation and loading in type 2 sockets has a significant influence on labial plate reconstruction, PES enhancement and primary stability elevation.
