Objectives: This crossover randomized controlled clinical trial (RCT) aimed to evaluate the clinical applicability of three-dimensional printed dentures (CAD-3DPs) by comparing two fabricated complete dentures, CAD-3DPs and conventional complete dentures (CCDs), and assess the non-inferiority of CAD-3DPs. The hypothesis was that CAD-3DPs would be inferior to CCDs in terms of the oral health-related quality of life (OHRQoL) and patient satisfaction.
Methods: This single-blind RCT was conducted at two university hospitals.
Purpose: This in vitro study investigated the effect of build orientation on the wear resistance and hardness of denture teeth fabricated using digital light processing (DLP) compared to other denture tooth materials.
Methods: Disc-shaped specimens were prepared using denture tooth monomers and DLP devices in three build orientations: 0°, 45°, and 90°. Specimens of the same shape were fabricated using denture tooth materials for subtractive manufacturing, commercially available polymethylmethacrylate (PMMA) resin, and composite resin.
Objectives: This study investigated the effects of different postrinsing times and methods on the surface roughness, surface hardness, and degree of polymerization of materials manufactured via stereolithography (SLA).
Materials And Methods: A total of 288 disk-shaped specimens were manufactured using an SLA three-dimensional (3D) printer. The specimens were randomly divided into nine groups ( = 32) based on rinsing times and methods.
Background/purpose: Gum chewing has been found to improve oral function. Nevertheless, few randomized controlled trials have investigated the effects of gum-chewing exercises on oral function in older adults. This study aimed to examine the effect of gum-chewing exercises on oral function in older adults.

- The study aimed to accurately predict the positional coordinates of incisor points using scan data from conventional complete dentures.
- By analyzing STL data from 100 pairs of dentures, researchers calculated the x, y, and z coordinates of incisor points and assessed the prediction accuracy through root mean squared error (RMSE) metrics.
- Results indicated that while the accuracy for predicting the X coordinate was RMSE of 2.22, the Y coordinate accuracy improved significantly by including additional facial measurements, achieving a lower RMSE of 0.73.
No specific methods have been officially proposed for the prevention and improvement of oral hypofunction. Therefore, in this randomized controlled trial, we aimed to develop a gum-chewing training program and determine its effects in older adults. A total of 218 older adults, aged 65-85 years, were randomly allocated to the intervention or control groups.

Methods: This was a follow-up study for a crossover randomized controlled trial comparing 1-IODs and conventional complete dentures, with patient satisfaction as the primary outcome. In the present study, the cognitive function of the patients, measured with the Japanese version of the Montreal cognitive assessment (MoCA-J), was evaluated as the secondary outcome at baseline and 2 months, 1 year, 2 years, and 3 years after 1-IOD placement.
Purpose Additive manufacturing has revolutionized the fabrication of complete dentures. However, this process involves support structure, which is a construction part that holds the specimen during printing, and may prove to be disadvantageous. Therefore, this in vitro study compared the effect of support structure reduction on various volume and area distributions of a 3D-printed denture base to determine optimal parameters based on accuracy.

The goal was to identify the most beneficial implant attachment system design for mini-implant overdentures with a lower risk of implant fracture.
Methods: Twelve 3D FE models simulating a mandible segment with one- and two-piece mini-implants with different attachment systems, diameters, and overdentures were created using three-dimensional computer-aided design (CAD) software.
Purpose: This study investigates the effect of different post-rinsing times and methods on the trueness and precision of denture base resin manufactured through stereolithography.
Materials And Methods: Ninety clear photopolymer resin specimens were fabricated and divided into nine groups (n = 10) based on rinsing times and methods. All specimens were rinsed with 99% isopropanol alcohol for 5, 10, and 15 min using three methods-automated, ultrasonic cleaning, and hand washing.
Background: Complete tooth losses are still being major problems which resulted in lesser quality of life especially for elderly patients. However, there are still lack of questionnaire to evaluate the treatment outcome from the patient's aspect. The objective of this study is to evaluate the reliability and validity of the Patient's Denture Assessment-Thai version (PDA-T), then use this questionnaire to assess patient satisfaction with complete denture treatment outcome also investigates the factors involving their satisfaction.
