1. Introduction

Recent advancements in digital dentistry have profoundly transformed patient-specific treatment strategies, leveraging state-of-the-art technologies such as artificial intelligence (AI), high-resolution 3D scanning, and additive manufacturing (3D printing) [1,2]. These technological innovations facilitate the fabrication of highly customized dental prosthetics, implants, and orthodontic appliances, significantly enhancing precision, functionality, and biocompatibility [3].

A critical challenge in contemporary dentistry lies in achieving optimal prosthetic fit and long-term clinical success while accommodating individual anatomical variations, patient-specific functional requirements, and pre-existing medical conditions [4,5]. Conventional methods, which predominantly rely on manual impressions and laboratory-based fabrication, are often associated with inaccuracies, extended treatment durations, and compromised patient comfort [6].

The integration of AI-driven 3D scanning and additive manufacturing addresses these limitations by enabling a fully digital workflow that improves the accuracy, efficiency, and predictability of clinical outcomes [7,8]. Moreover, there is a growing emphasis on the use of sustainable and biocompatible materials in dentistry, driven by global initiatives to reduce environmental impact [9].
