Performance of CAD/CAM Milled and 3D-printed Full-arch Implant-supported Provisionals Restorations

Spain20 participantsStarted 2022-03-01

Plain-language summary

This clinical trial aims to compare the performance of CAD/CAM-milled and 3D-printed full-arch implant-supported provisional restorations in patients at the Advanced Implant Prosthetics Clinic of the Complutense University of Madrid, of both sexes, over 18 years of age, edentulous upper, lower or both, whose treatment plan is at least a fixed implant-supported rehabilitation of the complete arch. The main question it aims to answer is if there are differences in the mechanical behavior and optical properties of the materials used as provisional materials in full-arch restorations on implants fabricated by CAD/CAM technology through machining or 3D printing. Participants will: \- Receive milled (control material: PMMA; Multilayer PMMA block, HUGE; Shandong Huge Dental Material Corporation) or printed (test material: 3D impression resin; VarseoSmile Temp, Bego Bremer Goldschägerei Wilh. Herbst GmbH \& Co. KG, Bremen) and they will be in provisional phase for 3 months doing daily life. Researchers will compare PMMA (Multilayer PMMA block, HUGE; Shandong Huge Dental Material Corporation) and the printed-resin (3D impression resin; VarseoSmile Temp, Bego Bremer Goldschägerei Wilh. Herbst GmbH \& Co. KG, Bremen) to see: * Mechanical behavior and the absence of complications, fracture of the structure, material jumping or wear, loosening, or detachment. * Optical properties, initial color, and degradation of the materials used

Inclusion Criteria: * Males and females at least 18 years of age. * Healthy patients; ASA I or ASA II. * Maxillary, mandibular, or both maxillary edentulous patients whose prosthetic treatment plan is a full-arch implant-supported fixed prosthesis. * Patients must have voluntarily signed informed consent, be willing and able to attend scheduled follow-up visits, and agree to have coded data collected and analyzed. Exclusion Criteria: * Any contraindications for oral surgical procedures. * Smokers classified as "heavy smokers" above 10 cigarettes per day (or more than 1 cigar per day) or smokers of chewing tobacco. * Subjects with drug or alcohol abuse. * Severe bruxing habits. * Conditions or circumstances that, in the opinion of the investigator, would preclude completion of participation in the study or interfere with the analysis of the study results.
