Abstract

An accurate tomographic technique is described for acquisition of optimal cross-sectional images of implant sites before implant surgery. The described technique is applicable to tomographic systems equipped with a cephalometric head positioner. This cross-sectional tomographic technique was performed on a series of patients and the images of the first 20 patients subsequently evaluated. The cross-sectional images allowed for the characterization of the alveolar crest and visualization of anatomic structures in a buccolingual dimension while providing an accurate estimation of available vertical space from the crest.

摘要

本文描述了一种精确的断层扫描技术，用于在种植手术前获取种植部位的最佳横断面图像。所描述的技术适用于配备头颅定位器的断层扫描系统。对一系列患者进行了这种横断面断层扫描技术，并随后对前20例患者的图像进行了评估。横断面图像能够对牙槽嵴进行特征描述，并在颊舌维度上显示解剖结构，同时能准确估计牙槽嵴处可用的垂直空间。
