Abstract

PURPOSE

The objective of this study was to assess the trabecular bone changes that occurred around functional endosseous dental implants by means of radiographic image analysis techniques.

MATERIALS AND METHODS

Immediate preoperative and postoperative periapical radiographs of de-identified implant patients at the University Dental Hospital of Manchester were retrieved, screened for specific inclusion criteria, digitized, and quantified for structural elements of the trabecular bone around the endosseous implants, by using image analysis techniques. Data were analyzed using SPSS version 11.5. P values of less than 0.05 were considered statistically significant.

RESULTS

A total of 12 implants from 11 patients were selected for the study, and 26 regions of interest were obtained. There was a significant increase in the bone area in terms of the mean distance between nodes (p=0.006) and a significant decrease in the marrow area in terms of the bone area (p=0.006) and the length of marrow spaces (p=0.032).

CONCLUSION

It appeared that the bone around the implant underwent remodeling that resulted in a net increase in bone after implant placement.

摘要

目的

本研究的目的是通过影像学图像分析技术评估功能性骨内牙种植体周围发生的小梁骨变化。

材料与方法

检索了曼彻斯特大学牙科医院身份不明的种植体患者术前即刻和术后根尖片，根据特定纳入标准进行筛选，数字化处理，并使用图像分析技术对骨内种植体周围小梁骨的结构元素进行量化。使用SPSS 11.5版软件对数据进行分析。P值小于0.05被认为具有统计学意义。

结果

共选取了11例患者的12枚种植体进行研究，获得了26个感兴趣区域。节点间平均距离方面骨面积显著增加（p = 0.006），骨面积和骨髓间隙长度方面骨髓面积显著减少（p = 0.006和p = 0.032）。

结论

种植体周围的骨似乎经历了重塑，导致种植体植入后骨量净增加。
