Abstract:
OBJECTIVETo evaluate the preliminary clinical results of application of All-on-4 immediate function in edentulous patients.
METHODSTwenty nine edentulous patients with 140 immediately loaded implants supporting fixed complete-arch all-acrylic prostheses from April 2008 to October 2009 in Peking University School of Stomatology were included. The implant-supported fixed complete-arch all-acrylic prostheses were delivery on the operation day. At time of abutments connection, a panoramic radiograph was taken. And radiographic assessment of the marginal bone level was performed in every 2 months. Clinical observe items included marginal bone level, integrity of the restoration, survival of the implants and degree of satisfaction of the patients.
RESULTSA total of 140 implants were immediate loading. Eight implants were lost during 6 - 8 weeks after immediate loading, giving survival rate of 94.3%. The marginal bone level was (0.8 ± 0.4) mm. The All patients were satisfied with the clinical results.
CONCLUSIONSThe data and the experience described in this study indicate that All-on-four immediate function technique can be a predictable technique for edentulous patients. Further study is needed to determine the long-term result of the technology.
