Abstract
Objective:This study analysis the stability of using osteotome sinus floor elevation to implant when the residual bone height in posterior maxilla area is less than 5 mm,providing references in the use of osteotome sinus floor ele-vation in clinical treatment when the alveolar ridge in posterior maxilla area suffers severe atrophy. Method:Separate the 65 patients into two groups which received implantation and restoration by using osteotome sinus floor elevation during October 2013 to October 2014 in our department. Group A:patients with the residual bone height less than 5 mm. Group B:patients with residual bone height between 5~10 mm. Measure the implant stability quotient of plants in the near, far, buccal, lingual both before the implant restoration modulus and after the implantation, then take the average record as the implant stability quotient, and make a comparison between these two groups to find if there is any difference in implant stability quotient both after the implantation and before restoration. Then, make an analysis on the differences of implants with different length and diameter in terms of stability. Result:Group A:implanted 30 implants (29 repaired);group B:implanted 54 implants (all re-paired). The survival rate of group A is 96.67%, while group B was 100%. The residual bone height of group A is 3.89±0.72 mm, while the second group was 7.79±1.52 mm. The implant stability quotient of group A improved from 67.28±1.70 after implantation to 76.31 ±2.22 before the implant restoration, while the implant stability quotient of group B improved from 69.51 ±1.60 after implantation to 76.65 ±2.49 before the implant restoration. The implant stability quotient of implants with the length of 8 mm and 10 mm is 76.75±2.71 and 2.71±2.37 before restoration, respectively. The implant stability quotient of implants with the diameter of 4.1 mm and 4.8 mm is 76.62 ±2.39 and 2.39 ±2.40 before restoration, respectively. Conclu-sion:By applying osteotome sinus floor elevation when the residual bone height in posterior maxilla area is less than 5 mm , the stability of implantation can be expected.关键词
