Functional Evaluation for 3D Printed Complete Dentures

Complete dentures have a long history and remain one of the principal treatment options for patients with complete edentulism. However, conventional fabrication involves a complex series of clinical and laboratory procedures, and the final prosthesis cannot be reproduced with complete accuracy. With recent advances in digital dentistry, integrating digital technologies into complete denture fabrication has become an important area of research. Current evidence indicates that digitally fabricated three-dimensional (3D)-printed complete dentures can reduce the number of clinical procedures and shorten treatment time. Nevertheless, clinical evidence comparing the performance of conventionally fabricated and digitally fabricated 3D-printed complete dentures remains limited. Therefore, this study aims to compare the advantages and disadvantages of these two types of complete dentures using various subjective and objective outcome measures after each participant has used both dentures for a specified period.

Inclusion Criteria: * Participants must be 20 years of age or older. * Participants must be completely edentulous in both the maxilla and mandible, with at least three months having elapsed since the most recent tooth extraction. * Participants must have sufficient cognitive ability to understand the study procedures and be able to read and complete the study questionnaires. * Participants must voluntarily agree to participate in all study procedures after receiving and understanding the study information. Exclusion Criteria: * Individuals who are unable to read or complete the study questionnaires. * Individuals with temporomandibular disorders that impair normal mouth opening and closing or prevent them from performing movements according to the investigators' instructions. * Individuals with maxillary or mandibular defects resulting from congenital conditions or surgical procedures. * Individuals whose physical or psychological health is considered unsuitable for study participation, as determined by the investigator or primary contact.
