Abstract:
Introduction: three-dimensional (3D) printing has transformed dentistry by enhancing precision, efficiency, and reducing material waste in prosthesis manufacturing. The objective of this study is to evaluates (3D) printing effectiveness and operational parameters by assessing technology used, workflow efficiency, patient outcomes and complications in dental procedures, focusing on its clinical applicability and impact on patient care. Method: a systematic literature review was done for articles from 2015 to 2024. A systematic search of multiple databases, including PubMed and Google Scholar, yielded 3785 studies, which were narrowed to 15 studies that focused on 3D printing technology in multi-part dental prostheses. Results: the 3D-printed material was compared with conventional rapid prototyping material, and good strength characteristics of the prostheses were achieved. 3D-printed prostheses’ long-term performance depends on constantly developing techniques and technologies. 3D-printed prosthesis accuracy was relatively high, but patient throughput, complexity, and limited precision needed to be more satisfactory. Literature reviews, randomized controlled trials, single-centre clinical trials, and in vitro and observational studies were also included in this study. Conclusions: although limitations about material properties, production costs, and accuracy still exist, the prospects of 3D printing for clinical application in dental prosthetics are very encouraging. Enhanced digital workflows have positively impacted patient engagement, yet additional research is needed to improve such practices in the clinic for maximal patient satisfaction.
