Comparing CAD/CAM-milled and 3D-printed full-arch dental restorations
Performance of CAD/CAM Milled and 3D-printed Full-arch Implant-supported Provisionals Restorations: A Randomized Controlled Clinical Trial
This study is testing whether dental restorations made by milling or 3D printing work better for patients without teeth over a three-month period.

What this trial studies
This clinical trial compares the performance of CAD/CAM-milled and 3D-printed full-arch implant-supported provisional restorations in edentulous patients. Participants will receive either milled or printed provisional restorations and will be monitored for three months to assess mechanical behavior and optical properties. The study aims to determine if there are significant differences between the two fabrication methods in terms of their effectiveness and durability. The research is conducted at the Advanced Implant Prosthetics Clinic of the Complutense University of Madrid.
Who should consider this trial
Good fit: Ideal candidates are healthy adults over 18 years old who are edentulous and require a full-arch implant-supported fixed prosthesis.
Not a fit: Patients with contraindications for oral surgical procedures or those with severe bruxing habits may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved dental restoration options for edentulous patients, enhancing both functionality and aesthetics.
How similar studies have performed: While the use of CAD/CAM technology in dental restorations is established, the specific comparison of 3D printing versus milling for full-arch provisional restorations is relatively novel.
Eligibility criteria
Show full inclusion / exclusion criteria
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.
