Abstract
Objective: To evaluate the correlation of clinical factors in the posterior maxillary sinus lift and immediate implant placement. Subject and method: A retrospective and cross-sectional descriptive study of 60 patients without maxillary molar and 3 - 8mm remaining bone height whom underwent implant placement and open sinus lift surgery with 83 implants. Result: The second molars accounted for 62.6%, the insertion torque forces were satisfactory with 62.7% more than 35N/cm2; the mean bone mass density was 69.9%; 71.1% of implants was under the crest bone. The ratio of bone resorption less than 1.5mm after 2 years was 62.7%. With two failure cases, the successful rate was 97.6%. There was a strong correlation between the bone resorption and the remaining bone height. The location and size of the implant were not closely correlated to the bone resorption and successful rate. Conclusion: This was a good technique with high successful rate. The bone resorption was effected by many factors.
