OBJECTIVE
Dental implant artifacts can compromise the quality of cone-beam computed tomography (CBCT) scans and challenge radiographic detection in surrounding regions. This literature review was conducted to examine the impact of implant angle modification on reducing metal artifacts in CBCT scans.
MATERIALS AND METHODS
A scoping review of literature was carried out in PubMed, Embase, Scopus, and Cochrane databases.
RESULTS
Different spatial planes, including alpha, beta, gamma, and phi, along with 0°, 5.2°, 9.8°, 14.5°, 15°, 30°, 45°, 60°, 75°, and 90° angles were studied. Changes in the angular position of implants may reduce metal artifacts and improve the quality of CBCT scans.
CONCLUSIONS
Rotating implants within the alpha plane and angling them at 90° in the alpha plane enables reducing dental implant artifacts.
目的
牙种植体伪影会影响锥形束计算机断层扫描（CBCT）的图像质量，并对周围区域的影像学检测构成挑战。本综述旨在探讨种植体角度调整对减少CBCT扫描中金属伪影的影响。
材料与方法
在PubMed、Embase、Scopus和Cochrane数据库中进行文献综述。
结果
研究了不同的空间平面，包括α、β、γ和φ平面，以及0°、5.2°、9.8°、14.5°、15°、30°、45°、60°、75°和90°的角度。种植体角度位置的改变可能会减少金属伪影并提高CBCT扫描的质量。
结论
在α平面内旋转种植体并使其在α平面内与平面呈90°角可减少牙种植体伪影。
