Abstract

Background£ºDental implantation has become predictable treatment for dental prosthodontics. But maxillary posterior jaw region is often complicated by the pneumatization of the maxillary sinus and physiological resorption of the alveolar bone. When this occurs, the residual bone between the floor of the sinus and the crestal ridge is inadequate for the placement of implants. The sinus lift and sinus floor elevation with osteotome procedures provide a way to increase the amount of available bone and to allow the placement of longer implants.
Materials & methods£ºWe studied 26 patients requiring the implant placements and the maxillary sinus elevation simultaneously from 1996 to 2007 in our clinic. Twenty were males and six were females, aged from 25 to 73 (mean=52.3). Fourteen patients had medical compromised states; angina pectoris, diabetes, hypertension, hepatitis, Penicillin allergy. All of the patients didn¡¯t show any pathologic findings clinically or radiographically. We studied the success and survival rate of implants and factors increasing the osseointegrating capacity of implants.
Results£ºThe success rate of osseointegration of implants with the maxillary sinus lift was 94%. The success rate of osseointegration of implants with the maxiilary sinus floor elevation used osteotome was 100%. At least 6 months after loading on implants, the survival rate of implants with the maxillary sinus lift was 82.3% and the survival rate of implants with the maxillary sinus floor elevation used osteotome was 100%. Autogenous bone graft and adequate residual bone height (>6mm) increased survival rate of implants.
Conclusion£ºSuccessful implant placement with maxillary sinus lift and maxillary sinus floor elevation used osteotome mainly depends on sufficient residual bone height, healthy maxillary sinus, autogenous bone graft.

Key Words: Maxillary sinus lift, Maxillary sinus floor elevation with osteotme, Endoosseous implant, Bone graft
