“…Improved denture base fit was also reported with PEEK denture base material 50 . On the contrary, others found that the retention and fit of the complete denture bases manufactured using CAD/CAM techniques were comparable to that of conventionally manufactured bases 51 …”

“…50 On the contrary, others found that the retention and fit of the complete denture bases manufactured using CAD/CAM techniques were comparable to that of conventionally manufactured bases. 51 The volumetric differences related to conventional denture base processing are no longer a problem because it is not present in case of CAD/CAM. As a result, when CAD/CAM-manufactured dentures were compared with conventional dentures, the fitting surface of the CAD/CAM fabricated dentures revealed a higher similarity to the master cast surface and provided more accurate and reproducible denture fabrication technique.…”

Background New materials for overdenture base construction were evolved. Thus, more clinical trials are needed to validate these materials. Objective This study aimed to compare the difference between CAD/CAM‐milled poly methyl methacrylate (PMMA), poly ether ether ketone (PEEK) and conventional mandibular implant‐assisted overdentures regarding patient satisfaction and oral health‐related quality of life (OHRQL). Methods This randomised, crossover, clinical study included 18 completely edentulous subjects rehabilitated with three mandibular implant‐assisted overdentures with three different denture base materials opposing a maxillary single denture. These materials were as follows: CAD/CAM‐milled PMMA, CAD/CAM‐milled PEEK and conventional PMMA. Every participant first received each mandibular overdenture in a random manner. After 6 months of each overdenture use, patient satisfaction and oral health‐related quality of life were assessed using visual analogue scale (VAS) and Oral Health Impact Profile (OHIP‐EDENT‐19), respectively, and then crossover to other groups was done. The same was repeated to the last group. Comparison of VAS and OHIP‐EDENT‐19 between groups was done using Kruskal–Wallis test followed by Bonferroni test. Results Regarding all the VAS items, there were statistically significant higher scores for CAD/CAM‐milled PMMA and PEEK than conventional PMMA base except for speech, aesthetic and smell. Regarding OHIP‐EDENT‐19, many items revealed statistically lower problem scores for CAD/CAM‐milled PMMA, and CAD/CAM‐milled PEEK than conventional PMMA base except psychological discomfort, psychological disability and social disability. Conclusion Within the limit of this study, CAD/CAM‐milled PMMA and CAD/CAM‐milled PEEK were recommended as implant‐assisted overdenture bases as it revealed higher patient satisfaction and better oral health‐related quality of life in comparison with conventional PMMA implant‐assisted overdenture.

“…The characteristics of the participant have been reported previously. 19 The results comparison indicates higher clinical retention forces of the bases from a conventional impression compared with those manufactured from a digital scan at all 3 testing locations, namely the post dam and the right and left tuberosities (Table 1). Table 2 reports on the comparison of clinical retention after 2 weeks of storage in artificial saliva, where the conventional impression generated higher clinical retention of the corresponding bases.…”

“…The details of the manufacturing methods and materials used, as well as the platform design, have been reported previously. 19 The denture bases were sprayed with an antiglare scanning spray (Helling 3D Scan Spray; Helling GmbH) and scanned with a calibrated laboratory scanner (Iscan D103i; Imetric 3D SA). 20 Data from the scans were stored in a standard tessellation language (STL) format.…”

“…In-vitro and in-vivo testing often provide different results, so understanding if this difference is of clinical significance is important. The first to clinically evaluate conventional, milled and printed denture retention were Maniewicz et al, 25 who found similar retention and fit of milled and printed maxillary dentures when compared to conventionally processed dentures. Thus, the differences in denture base adaptation found in the lab are likely not of clinical significance.…”

To explore the applications of 3D printing for the fabrication of complete dentures, a literature search was conducted using PubMed to identify articles related to the topic of 3D-printed complete dentures. A search was conducted that included the following keywords: digital complete denture workflow, printed complete denture, additive manufacturing complete denture, digital complete denture, CAD/CAM complete denture. Articles published before 2016 were excluded to increase the relevancy of reporting results. Determining how 3D-printed dentures compare to conventional and milled dentures is important to better understand how they can be used clinically. Material strength, color stability, and denture base adaptation are discussed. Currently, the area of greatest innovation is with printing resins and improving physical and esthetic properties. As with every innovation, multiple generations of materials are created before the gold standard is achieved. While the ideal printed denture material does not currently exist, based on the published research, printed dentures have material strength that meets ISO standards, with denture base adaptation similar to conventionally processed dentures. Clinically, it is likely that printed dentures will have more challenges with fractures, color stability, and staining. However, printed dentures offer many benefits, and the current limitations will be addressed as new materials are developed. We are currently at the beginning of what is an exciting future for printed dentures.
