Since the development of CBCT has been utilized in dentistry, the images of the CBCT can assist the surgeon to evaluate the anatomy carefully. Despite the value of radiology evaluation, implant procedures may require additional consideration rather than only evaluating the anatomical factors. The purpose of this study is to evaluate the predictability of using CBCT alone to plan for implant placement in edentulous patients digitally. CBCT images were analyzed by clinicians, measuring the maxillary and mandibular ridge heights and widths digitally of four predetermined implant sites in the maxillary and two selected implant sites in the mandibular arches of 91 patients planning for implant-supported overdenture. A total of 47 patients out of the 91 had completed implant placement on the edentulous ridge, contributing to 55 upper and/or lower arches (136 dental implants). Both predictabilities are low, implying that CBCT planning for implant placement on the edentulous ridge is not a good index and is insufficient to predict the surgical procedures as a solo method. The findings of this study indicate that digital planning by CBCT is insufficient to serve as an individual tool to predict implant procedures. Further information and evaluation must be considered for implant placement in the edentulous ridge.
自从锥形束计算机断层扫描(CBCT)技术在牙科领域得到应用以来,CBCT图像能够辅助外科医生仔细评估解剖结构。尽管放射学评估具有重要价值,但种植手术可能需要更多考量,而不仅仅是评估解剖因素。本研究的目的是评估单纯使用CBCT对无牙颌患者进行数字化种植体植入规划的可预测性。临床医生对CBCT图像进行分析,数字化测量了91例计划进行种植支持式覆盖义齿修复患者上颌四个预定种植位点以及下颌两个选定种植位点的牙槽嵴高度和宽度。91例患者中有47例已在无牙颌牙槽嵴上完成种植体植入,共计55个上和/或下牙弓(136颗牙种植体)。两种可预测性均较低,这意味着CBCT对无牙颌牙槽嵴种植体植入的规划并非一个良好指标,作为单一方法不足以预测手术过程。本研究结果表明,CBCT数字化规划不足以作为预测种植手术的独立工具。在无牙颌牙槽嵴进行种植体植入时,必须考虑更多信息和评估。
