Abstract
PURPOSE Gaining knowledge on the extent of digital technology implementation in dental education and the barriers to it will help inform future directions to promote the use of such technology and will enhance dental education. This study aimed to investigate the utilization of digitally fabricated removable prostheses and the potential obstacles to implementing such technology in US dental schools. METHODS A survey was developed and distributed to the restorative dentistry department chairs and postdoctoral prosthodontic program directors. The survey delivery protocol included follow-up emails 1 week, 3 weeks, and 4 weeks after the initial email. The collected data were analyzed descriptively. RESULTS The response rate was 85% and 45% for predoctoral and postdoctoral prosthodontic programs, respectively. The results showed that 88.06% of the predoctoral programs and 95.65% of the postdoctoral prosthodontic programs implement digital complete dentures in the curriculum; however, the digital removable partial dentures implementation rate was recorded at 70.77% in predoctoral programs and 61.9% in postdoctoral prosthodontic programs. CONCLUSIONS Dental schools are challenged by cost, design software limitations, IT and laboratory support, and faculty training. Multifaceted support is instrumental in further implementing digital removable prosthodontics into dental education.

Abstract
Digital technology facilitates the manufacturing of complete dentures; however, clinical and patient-reported outcomes are underreported. This prospective, randomized, single-blind cross-over study reports the clinical and patient-related outcomes of 10 edentulous patients receiving digital dentures prepared with the Vita Vionic System and conventional dentures produced from heat-polymerized polymethylmethacrylate resin. Clinical efficiency was stated based on the Sato score for quantitative assessment of complete denture quality. Patient satisfaction was evaluated with the oral health-related quality of life questionnaire (OHIP-20). We report here that the Sato score was slightly higher in patients receiving digital versus conventional dentures with a mean of 73.2 ± 12.3 and 67.4 ± 11.8, respectively (p = 0.16). Moreover, upper and lower stability was superior in digital dentures (p = 0.03 and p = 0.10, respectively), while denture polish was better in conventional dentures (p = 0.03). Quality of life was slightly higher in patients receiving conventional compared to digital dentures with an OHIP-20 of 101.7 ± 12.0 and 95.6 ± 24.2, respectively (p = 0.33). Taken together and when considering the low power of the study, our findings suggest a trend towards better clinical efficiency of digital compared to conventional dentures, while patient satisfaction remained unaffected by the type of manufacturing.

Abstract
The objective of this survey was to evaluate the knowledge, awareness, and practice of digital dentures among dentists. This is a cross-sectional survey conducted from January to February, 2022. Fifteen close-ended questions were framed and circulated among 150 dental practitioners and interns using an online survey form. The responses were collected and statistically analyzed. The results summarize that 95.3% were aware of digital dentures and 4.7% were not. About 60.1% do not use digital workflow, 27% do not have essential equipment, 9.5% were not confident in practicing digital dentures, and 3.4% found that it was inaccurate, showed poor retention, and a well-skilled technician was required. Most dental practitioners are aware of digital dentures. Among all practitioners with postgraduation were more aware of digital dentures than the interns and undergraduate practitioners. Most dentists do not practice digital dentures due to the high initial setup cost and maintenance. The majority of practitioners agree that digital dentures will be the ultimate tool in future dentistry.

Abstract
PURPOSE To investigate surface characteristics (roughness and contact angle), anti-biofilm formation, and mechanical properties (mini-flexural strength) of computer-aided design and computer-aided manufacturing (CAD-CAM) PMMA polymer, and three-dimensional (3D) printed resin for denture base fabrication compared with conventional heat polymerized denture base resins. MATERIALS AND METHODS A total of 60 discs and 40 rectangular specimens were fabricated from one CAD-CAM (AvaDent), one 3D printed (Cosmos Denture), and two conventional heat polymerized (Lucitone 199 and VipiWave) materials for denture base fabrication. Roughness was determined by Ra value; the contact angle was measured by the sessile drop method; the biofilm formation inhibition behavior was analyzed through C. albicans adhesion, while mini-flexural strength test was done using a three-point bending test. The data were analyzed using descriptive and analytical statistics (α = 0.05). RESULTS The CAD-CAM PMMA group showed the lowest C. albicans adhesion (log CFU/mL: 3.74 ±0.57) and highest mini-flexural strength mean (114.96 ±16.23 MPa). 3D printed specimens presented the highest surface roughness (Ra: 0.317 ±0.151 μm) and lowest mini-flexural strength values (57.23 ±9.07 MPa). However, there was no statistical difference between CAD-CAM PMMA and conventional groups for roughness, contact angle, and mini-flexural strength. CONCLUSIONS CAD-CAM milled materials present surface and mechanical properties similar to conventional resins and show improved behavior preventing C. albicans adhesion. Nevertheless, 3D printed resins present decreased mini-flexural strength. This article is protected by copyright. All rights reserved.

Abstract
PURPOSE To evaluate and compare the benefits and limitations of additive manufacturing for complete denture fabrication. METHODS A PubMed and Google Scholar search for topics pertaining to additive manufacturing for complete dentures was performed. The resulting articles were then divided into topics to allow a narrative review. DISCUSSION Determining how printing compares with conventional and milled dentures is critical for the widespread adoption of this fabrication technique. Physical properties, denture tooth bond strength, denture base adaptation and soft-liner bond strength are discussed to establish how printing compares. CONCLUSIONS Printing offers many advantages over milled and conventionally processed dentures; however, many questions need to be answered by research. The advantages include reduced cost of most printers compared to milling machines, less material waste, ability to print multiple dentures simultaneously, and complex designs can be fabricated that otherwise could not be milled. Current research has shown flexural strength, fracture toughness, color stability, and denture base adaptation are reduced for printed dentures when compared with milled dentures. Print orientation has been shown to influence accuracy, strength, surface roughness and C. albicans adherence which is not seen with conventional or milled denture materials. These factors do not represent a criticism of printing but rather indicate the need for more research with this new and promising denture fabrication technique. Since printing offers numerous benefits to complete denture fabrication it is likely to have a more significant role in complete denture fabrication in years to come as knowledge increases and materials/techniques continue to advance.

Abstract
AIMS To establish the prevalence of jaw registrations being taken for removable partial dentures (RPDs) in primary dental NHS practices. METHOD 271 RPDs made by 16 general dental practitioners across four NHS dental practices were evaluated prospectively. The number of teeth replaced, whether jaw registration was undertaken, and the number of denture adjustment appointments were recorded. Telephone interviews with dental technicians were held to establish their preferred jaw registrations material. MAIN FINDINGS Jaw registrations were not carried out in 27% (n=72) of RPD. When jaw registration was recorded, 14% (n=28) required a further denture adjustment appointment. 64% (n=46) of dentures where jaw registration was not recorded required at least one further denture adjustment appointment. Dental technicians unanimously preferred a squash-bite wax block, with centre and canine positions marked and cast models secured with elastic bands. CONCLUSION Overall, recording a jaw registration reduced the number of denture adjustment appointments required.
