The use of e-PTFE barrier membranes for bone promotion around titanium implants placed into extraction sockets: a prospective multicenter study

摘要: This multicenter study was conducted to determine the predictability for implants placed into immediate extraction sockets and augmented with e-PTFE barrier membranes. Forty-nine were in sockets. Initial final defect measurements number of threads exposed compared. Patients followed up 1 year after implant loading. Three lost at abutment connection surgery. The 1-year survival rate 93.9%. Twenty membranes became removed prior stage 2 surgery, while remaining barriers connection. average bone formation membrane-retained sites 4.8 mm, which prematurely 4.0 mm (P < .0001). At surgery there an 0.6 .001) 2.6 early removal (NS). Forty-five pairs nonstandardized radiographs evaluated loss loading (average 7.5 months). mesiodistal averaged 0.72 mm. Within limits this study, will promote clinically statistically significant amounts around immediately implants. Retention until improves amount promoted
