Safety and performance of the first supervised automated dental robot to perform minimally invasive tooth prep for laminate veneers.

Résumé fourni par la source

OBJECTIVE: In this prospective clinical study, the safety and performance of the Lupin Robotic System in tooth preparation for veneer procedures in adult patients have been investigated. METHODS: A total of 12 patients (52 teeth treated from 2 teeth to 6 anterior teeth) were fully treated with Lupin Robotic System performing minimally invasive tooth preparation for laminate veneers. The tooth prep was scanned and compared with the ideal planned tooth prep. The teeth prepared in this current study were classified as Minimally invasive preparation (MIP) or Non-Minimally invasive preparation (NP) by the investigating dentist following criteria based on the state of the art of minimal preparation methods. The methodology is well described in the literature, but may be summarized as: Enamel surface preservation / dentine exposure; preparation margins clarity; tooth preparation which respects convexity; homogenous space between the prepared tooth and final design (i.e. appropriate thickness of the veneer); presence of butt margin at the incisal edge. Each criteria has to be met to define a tooth as MIP. Safety was assessed through the collection of number and frequency of occurrence of all Adverse Events, including the D evice Deficiencies (DDs) that might have led to a safety event and DDs that do not lead to a safety event. RESULTS: The Root Mean Square (RMS) errors between the planned and the actual tooth surface preparations demonstrated high reproducibility of the robotic system. The RMS errors centered around 0.15 mm, with a range from 0.04 mm to 0.26 mm. These findings suggest accurate adherence to the pre-defined milling plan. The maximum error (MaxError) observed across the dataset indicate consistent compliance with key clinical preparation standards. MaxError was centered around 0.68mm, with a range from 0.47mm to 0.9mm, demonstrating a high level of uniformity in preparation outcomes. This distribution reflects reliable preservation of enamel, clarity of margins, and anatomical contouring during the veneer preparation process, supporting the overall procedural reliability of the system. SIGNIFICANCE: Overall, this dataset supports the conclusion that the analyzed preparation method achieves both precision and safety across a variety of clinical cases. The consistency across patients and tooth types highlights a controlled and reproducible process, providing strong indicators of quality in dental care delivery.
