Abstract

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.

锥形束ct图像中植入物角度位置的变化对金属伪影减少的影响:范围综述。

目的:种植体假影会影响锥形束计算机断层扫描(CBCT)的扫描质量，并对周围区域的放射检测构成挑战。本文献综述旨在探讨种植体角度改变对减少CBCT扫描中的金属伪影的影响。材料和方法:在PubMed, Embase, Scopus和Cochrane数据库中对文献进行了范围审查。结果:研究了0°、5.2°、9.8°、14.5°、15°、30°、45°、60°、75°和90°角度的α、β、γ和φ等不同空间平面。改变植入物的角度位置可以减少金属伪影，提高CBCT扫描质量。结论:在α平面内旋转种植体并在α平面内倾斜90°可减少种植体假影。
