“…42 These observations could be related to the improved mechanical properties of digitally fabricated alloys compared to conventional alloys. 12,30,48,49 Regarding PEEK RPDs, patients were significantly more satisfied with PEEK RPDs compared to conventionally fabricated metal RPDs, and this was related to esthetics, retention, and stability as reported in one study. 40 In the other study, there was no significant difference in patient satisfaction, oral health-related quality of life, and denture preference between PEEK and conventional metal RPD.…”

“…The results of this review are in agreement with previous systematic reviews. [27][28][29][30] However, these reviews included only one or two clinical comparative studies, most of the included studies were in vitro studies and case reports. [27][28][29] The results of this review confirmed previous results with six included comparative clinical studies of a higher level of evidence.…”

“…25,26 Previous systematic reviews concluded that both digitally and conventionally fabricated RPDs showed acceptable fit in the patient's mouth. 15,[27][28][29][30] They also pointed out the scarcity of published clinical studies on this topic and had therefore pooled data from in vitro studies, yielding weak evidence to support clinical decisions. 15,[27][28][29] More clinical studies have been published since then, 25,31,32 which could answer pending questions on the effectiveness of these new technologies with higher levels of evidence.…”

PurposeThis review aimed to summarize the evidence on patient‐reported outcomes and clinical performance of digitally fabricated removable partial dentures (RPDs) compared to traditionally fabricated dentures.MethodsThree databases were systematically searched (PubMed, CENTRAL, and Wiley online library) for clinical studies comparing digitally and conventionally fabricated RPDs regardless of data acquisition methods used for fabrication. The Cochrane Collaboration risk of bias assessment tool 2 and the Oxford Center for Evidence‐based Medicine tool were used to assess risk of bias, and level of evidence, respectively. Descriptive narrative analysis was used to summarize data on patient‐reported outcomes, as there were inadequate studies to pool data in a meta‐analysis. A random‐effects model was used to analyze the data of framework fit accuracy.ResultsTen randomized controlled trials were included in the systematic review, and 4 were included in the meta‐analysis. Two studies showed that digitally fabricated RPDs are associated with higher patient satisfaction than conventionally fabricated RPDs (with a mean difference of 12.5 mm on a 100‐satisfaction scale, p = .008). The pooled standardized mean difference for framework fit accuracy was 0.49 (p = 0.02) in favor of conventionally fabricated RPDs, which showed that conventionally fabricated RPDs have a quantitatively better fit compared to digitally fabricated RPDs. However, clinical evaluation studies showed that both frameworks have clinically acceptable fit.ConclusionsCurrent evidence shows that digitally fabricated RPDs are associated with higher patient satisfaction compared to conventionally fabricated RPDs. However, the scarcity of literature here warrants the generalization of this conclusion. Both digitally and conventionally fabricated metal RPD frameworks showed acceptable fit clinically.

“…The CAD designs for prostheses of four types of teeth defects could be satisfactorily copied into the PEEK framework. Although the comprehensive structure of the framework suffered some slight alterations during the processing, these modifications did not affect the final PEEK framework, which met the existing clinical requirements for the trueness of the removable partial denture [ 30 ].…”

The object of the study was to evaluate the suitability and trueness of the removable partial denture (RPD) framework fabricated by polyether ether ketone (PEEK) with the CAD-CAM technology in vitro. Four different types of dentition defects were selected. In each type, five PEEK RPD frameworks were fabricated by the CAD-CAM technology, while five Co-Cr RPD frameworks were made by traditional casting. The suitability of the framework was evaluated by silicone rubber film slice measurement and the three-dimensional image overlay method. The trueness of the PEEK framework was detected by the three-dimensional image overlay method. Data were statistically analyzed with the use of an independent samples t-test (α = 0.05). The suitability values by silicone rubber film slice measurement of the PEEK group were lower than those of the Co-Cr group in four types, with the differences indicating statistical significance (p < 0.05) in type one, type two, and type four. The suitability values using the three-dimensional image overlay method showed no statistical differences (p > 0.05) between the two groups in four types. The trueness values of the PEEK group were within the allowable range of clinical error. The suitability and trueness of the PEEK RPD framework fabricated by CAD-CAM technology met the requirements of the clinical prosthesis.
