Abstract Background The purpose of this paper is to review the available literature on three-dimensionally printed complete dentures in terms of novel biomaterials, fabrication techniques and workflow, clinical performance and patient satisfaction. Methods The methodology included applying a search strategy, defining inclusion and exclusion criteria, selecting studies and forming tables to summarize the results. Searches of PubMed, Scopus, and Embase databases were performed independently by two reviewers to gather literature published between 2010 and 2020. Results A total of 126 titles were obtained from the electronic database, and the application of exclusion criteria resulted in the identification of 21 articles pertaining to printed technology for complete dentures. Current innovations and developments in digital dentistry have successfully led to the fabrication of removable dental prostheses using CAD/CAM technologies. Milled dentures have been studied more than 3D printed ones in the currently available literature. The limited number of clinical studies, mainly case reports, suggest current indications of 3D printing in denture fabrication process to be custom tray, record bases, trial, interim or immediate dentures but not definitive prostheses fabrication. Limitations include poor esthetics and retention, inability to balance occlusion and low printer resolution. Conclusions Initial studies on digital dentures have shown promising short-term clinical performance, positive patient-related results and reasonable cost-effectiveness. 3D printing has potential to modernize and streamline the denture fabrication techniques, materials and workflows. However, more research is required on the existing and developing materials and printers to allow for advancement and increase its application in removable prosthodontics.

The purpose of this systematic review is to collate and analyse the current literature which examines clinical applications of 3D printing for renal disease, alongside cost and time duration factors associated with the printing process. A comprehensive search of the literature was performed across five different databases to identify studies that qualitatively and quantitatively assessed the value of 3D-printed kidney models for renal disease. Twenty-seven studies met the selection criteria for inclusion in the review. Twenty-five were original studies, and two were case reports. Of the 22 studies reporting a qualitative evaluation, the analysis of findings demonstrated the value of the 3D-printed models in areas of clinician and patient education, and pre-surgical simulation for complex cases of renal disease. Of five studies performing a quantitative analysis, the analysis of results displayed a high level of spatial and anatomical accuracy amongst models, with benefits including reducing estimated blood loss and risk of intra-operative complications. Fourteen studies evaluated manufacturing costs and time duration, with costs ranging from USD 1 to 1000 per model, and time duration ranging from 15 min to 9 days. This review shows that the use of customised 3D-printed models is valuable in the education of junior surgeons as well as the enhancement of operative skills for senior surgeons due to a superior visualisation of anatomical networks and pathologic morphology compared to volumetric imaging alone. Furthermore, 3D-printed kidney models may facilitate interdisciplinary communication and decision-making regarding the management of patients undergoing operative treatment for renal disease. It cannot be suggested that a more expensive material constitutes a higher level of user-satisfaction and model accuracy. However, higher costs in the manufacturing of the 3D-printed models reported, on average, a slightly shorter time duration for the 3D-printing process and total manufacturing time.

AbstractRecently, digital techniques have revolutionized the production of partial removable dental prostheses (PRDPs). This chapter reviews current systems for PRDP production, how they are done in clinical practice, advantages and limitations, and current literature regarding their clinical performance. Currently, several digital techniques are available in the market for PRDP production including subtractive and additive techniques. Subtractive milling technique is mainly effective for non-metal PRDP, whereas additive techniques are used mainly in metal PRDP. Digital techniques expand the range of materials that can be utilized for PRDP production, including new polymers (PEEK), and facilitate previously difficult procedures such as casting titanium PRDP, which can be produced more easily with digital methods. This review shows that available evidence suggests that these techniques have promising clinical results. Laser sintering resulted in higher patient’s satisfaction compared to conventional PRDP. However, long-term clinical trials are recommended to explore the long-term effects of these techniques. Moreover, this review showed the lack of evidence on the clinical performance of non-metal partial removable dental prostheses.

The aim of the present study was to evidence the improved behavior of our modified PMMA-TiO2 nanocomposite material used to obtain 3D printed complete dentures. A protocol for long-term rapid prototyping complete denture manufacturing using our nanocomposite material, completely characterized and the evaluation of the clinical performance and complications after eighteen months of continuous wearing was also described. Thirty-five fully edentulous patients were enrolled in this prospective clinical study and forty-five complete dentures (31 maxillary and 14 mandibular) have been obtained using an additive manufacturing technology. Due to the good performances of the nanocomposite material, no major functional complications for the obtained medical devices occurred and the clinical outcomes for the 3D printed dentures were favorable evaluated at eighteen months follow up.

Limited Accuracy

CAD/CAM milling systems provide a rapid and individual method for the manufacturing of zirconia dental restorations. However, the disadvantages of these systems include limited accuracy, possible introduction of microscopic cracks, and a waste of material due to the principle of the ‘subtractive process’. The hypothesis of this study was that these issues can be overcome by a novel generative manufacturing technique, direct inkjet printing. A tailored zirconia-based ceramic suspension with 27 vol% solid content was synthesized. The suspension was printed on a conventional, but modified, drop-on-demand inkjet printer. A cleaning unit and a drying device allowed for the build-up of dense components of the size of a posterior crown. A characteristic strength of 763 MPa and a mean fracture toughness of 6.7 MPam0.5 were determined on 3D-printed and subsequently sintered specimens. The novel technique has great potential to produce, cost-efficiently, all-ceramic dental restorations at high accuracy and with a minimum of materials consumption.

Fixed Dental Prostheses

Although CAD/CAM ceramics present a promising alternative to metal-ceramic fixed dental prostheses, little is known about their mid- and long-term clinical performance. This systematic review aims to estimate the survival and success rates and describes the underlying complication characteristics for CAD/CAM tooth-supported zirconia- and lithium disilicate-based fixed dental prostheses (FDPs). We systematically searched MEDLINE and Web of Science to find relevant prospective studies with a follow-up of at least one year. We estimated pooled 1-, 5-, and 10-year survival and success rates by combining the collected data in a Poisson regression model. Descriptive statistics were conducted to evaluate the distribution of failures and complications in the included studies. Risk of bias for the included studies was assessed with an adapted checklist for single-arm trials. Pooled estimated 1-, 5-, and 10-year survival rates ranged from 93.80% to 94.66%, 89.67% to 91.1%, and 79.33% to 82.20%, respectively. The corresponding success rates excluding failures, but including any other types of intervention were 94.53% to 96.77%, 90.89% to 94.62%, and 81.78% to 89.25%. Secondary caries was the most frequent cause of failure, followed by chipping of the veneering. The most common cause of complication excluding failures but requiring intervention was chipping of the veneering. Risk of bias was generally acceptable for the included studies, with seven studies associated with low risk of bias, eight studies with a moderate risk of bias, and three studies with serious risk of bias. The current meta-analysis on CAD/CAM-supported FDPs revealed satisfying survival and success rates for up to 10 years of exposure. More prospective studies focusing on long-term performance are needed to strengthen the evidence currently available in the literature.

Background: Advanced computer-aided design and computer-aided manufacturing (CAD-CAM) technology led to the introduction of an increasing number of machinable materials suitable for dental prostheses. One of these materials is polyetheretherketone (PEEK), a high performance polymer recently used in dentistry with favorable physical, mechanical and chemical properties. Purpose: The aim of this study was to review the current published literature on the use of PEEK for the fabrication of dental prostheses with CAD-CAM techniques. Methods: Electronic database searches were performed using the terms “PEEK”, “CAD-CAM”, “dental”, “dentistry” to identify studies related to the use of PEEK for the fabrication of CAD-CAM prostheses. Results: A great number of in vitro studies are available in the current literature pointing out the noticeable properties of PEEK. The use of PEEK has been recommended for a wide range of CAD-CAM fabricated fixed and removable dental prostheses, occlusal splints, intra-radicular posts, implant abutments, customized healing abutments, space maintainers for pediatric dentistry, orthodontic appliances and provisional restorations. However, only a few clinical studies were identified. Conclusions: PEEK could be considered as a viable alternative for CAD-CAM dental appliances to well-established dental materials. Due to the scarcity of clinical data, clinical trials are needed to assess the longterm performance of PEEK prostheses.

Background: Computer-aided design and computer-aided manufacturing (CAD-CAM) techniques have lately become a popular treatment option for complete dentures fabrication. The two principal CAD-CAM techniques milling and 3D printing used in complete dentures construction have been approved and documented in showing clinically good results. Surface characteristics of dentures fabricated by these new techniques have a great effect on microbiological adherence to denture fitting surfaces. Aim: As other clinical trials and/or in-vitro studies evaluating the microbiological effect and its correlation with the surface roughness of the two advanced manufacturing techniques and comparing it with the conventional technique are lacking. Thus, this study aimed to further assess the microbiological and surface properties of different widely used denture base materials. Methodology: Thirty-six completely edentulous patients were selected and divided randomly into three groups Group I patients received conventional complete denture, Group II patients received CAD/CAM milled complete dentures and Group III patients received 3D printed complete dentures. All denture`s surface roughness were evaluated, also all patients were recalled after 3, 9 & 12 months respectively to evaluate the microbiological adherence. Results: Microbiological count significantly increased (P < 0.05) after 12 months in all groups, after 12 months there was a significant difference (P < 0.05) between three groups as group II (Milled) was significantly the lowest, then the group I (conventional), while group III (3D printed) was significantly the highest. Regarding surface roughness of group II (milled) was significantly the lowest, while group III (3D printed) was significantly the highest. Finally, there was a strong positive significant correlation between microbiological adherence and surface roughness in all groups as (r > 0.5). Conclusion: Group II (Milled) appeared to be the best regarding microbiological adherence and surface roughness followed by the group I (conventional) and finally group III (3D printed). Furthermore, it was evident that surface roughness has a great effect on microbiological adherence regardless of the fabrication technique utilized.

Background: 3D printed complete dentures fabrication with computer-aided designing and computer-aided manufacturing (CAD/CAM) techniques is becoming popular nowadays. However, studies that analyzed the occlusal forces distribution using recent digital methods as T-scan III and further evaluated the dentures effect on patient`s life quality were lacking. Objectives: Evaluation of the occlusal forces distribution using T-scan III, and evaluation of the oral health-related quality of life (OHRQoL) using Oral Health Impact Profile for Edentulous Patients (OHIP-EDEN) questionnaire for 3D printed complete dentures and comparing it with conventional denture fabrication techniques. Methods: Twenty completely edentulous patients were selected and divided randomly into two equal groups according to manufacturing technique group I (patients who received conventional complete dentures), and group II (patients who received 3D printed complete dentures). For all patients, occlusal force analysis (percentage of applied occlusal force on both sides) was performed using the T-Scan III (digital occlusal analysis system). Also, OHRQoL was assessed using (OHIP-EDENT) questionnaire. Results: In the digital occlusal analysis, comparison between right and left sides regarding occlusal forces distribution revealed a significant difference in group I (conventional denture), while in group II (3D printed denture), it revealed an insignificant difference. Regarding, OHIP-EDENT patients in group I (conventional denture) revealed higher scores than group II (3D printed dentures). Also, the correlation between occlusal forces & (OHIP-EDENT) scores revealed a strong negative significant correlation. Conclusions: The 3D printed complete dentures fabricated using CAD/CAM technology proved to be more superior over conventional methods in terms of digital occlusal force analysis and Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT). However, further studies are required on more patients to decide the exact superiority of one technique over the other after long-term follow-up periods.
