Abstrakt: 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.
Competing Interests: The authors stated that there were no conflicts of interest regarding the publication of this paper.
