Abstract

Objective: Bone volume fraction (BV/TV) was used as a quantitative indicator of bone mineral density (BMD) in the posterior dental implant area, and the relationship between it and the initial stability of the implant was analyzed.

Methods: 53 patients with posterior dental implantation were selected. Remove the bone fragments from the planting area and put them in the formalin solution. Then, the implant was placed after the operator prepared the hole step by step. Peak Insertion torque value (ITV) and Implant stability quotient (ISQ) were recorded. The BV/TV of the bone fragments was measured by Image pro Plus6.0. The correlation between it and ITV and ISQ was analyzed.

Results: BV/TV was correlated with ITV and ISQ in the posterior dental planting area (r=0.862, r=0.832, P < 0.05). The correlation of the parameters in the posterior part of maxilla was higher than that in the mandible. There were significant differences in BV/TV, ITV, and ISQ between the mandible and maxilla, and the implant area of the mandible was higher than that of the maxilla.

Conclusion: BV/TV can provide an objective index for BMD in the implant area, which has an important influence on the evaluation of the initial stability of the implant.
