Simultaneous sinus lift and implant installation: prospective study of consecutive two hundred seventeen sinus lift and four hundred sixty-two implants.

摘要: Purpose If less than 4 mm of residual bone is remained in posterior maxilla, two-stage operation recommended for implant installation. However, if primary stability could be obtained using tapered designed implants, one-stage surgery performed with reliable success rate severely resorbed maxilla. The purpose this prospective study was to evaluate survival and rates the implants simultaneously placed into grafted sinus rough-surfaced implant. Materials Methods A total two hundred seventeen consecutive lifting through lateral approach four sixty-two simultaneous were installed from November 2003 5.5 years. Xenogenic used solely graft materials. Second around 6 months after porcelain fused metal or gold crown definitive restorations. Cumulative evaluated according alveolar height (RABH), smoking status, Schneiderian membrane perforation. Results The mean follow-up 57.1 ± 15.6 (36–98) months. Of (56.7%: group 1) maxilla 4-mm RABH (43.3%: 2) over 5-mm RABH. cumulative 98.91% 96.54%. There no statistically significant difference between 1 2 (p = .3135). Perforation not related (p = .7162), but status significantly failure (p = .0003). Conclusions Sinus placement treat atrophic patients minimal when initial by taper surgical techniques. Smoking a possible factor failure. Membrane perforation did have an adverse effect on repaired absorbable fibrin glue.
