The present study aimed to assess the eighteen month follow-up patient-centered outcomes of a simple and predictable protocol for 3D-printed functional complete dentures manufactured using an improved poly(methyl methacrylate) (PMMA)–nanoTiO2. A detailed morphological and structural characterization of the PMMA–TiO2 nanocomposite, using SEM, EDX, XRD, and AFM, after 3D-printing procedure and post-wearing micro-CT, was also performed. Methods: A total of 35 fully edentulous patients were enrolled in this prospective study. A 0.4% TiO2-nanoparticle-reinforced PMMA composite with improved mechanical strength, morphologically and structurally characterized, was used according to an additive computer-aided design and computer-aided manufacturing (CAD/CAM) protocol for complete denture fabrication. The protocol proposed involved a three-step appointment process. Before denture insertion, 1 week, 12 month, and 18-month follow up patients were evaluated via the Visual Analogue Scale (VAS, 0–10) and Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT), with a higher score meaning poor quality of life. Results: A total of 45 complete denture sets were inserted. OHIP-EDENT scored significantly better after 18 months of denture wearing, 20.43 (±4.42) compared to 52.57 (±8.16) before treatment; mean VAS was improved for all parameters assessed. Conclusions: Within the limitations of this study, we can state that the proposed workflow with the improved material used is a viable treatment option for patients diagnosed with complete edentulism.

Objective: The aim of this case report is to describe the treatment of a primary molar with a deep carious lesion by pulpotomy and placement of a ceramic endocrown. Clinical case: A 7-year-old male patient with profound caries in tooth number 85 was referred to our clinic and underwent a pulpotomy. As the final treatment in tooth restoration, placement of an endocrown was planned, because little more than half of the tooth structure remained. After an additional request from the patient's parents for an advanced and prompt restoration, a computer-aided design/computer-aided manufacturing (CAD/CAM) polymer-infiltrated ceramic network (PICN) block was chosen. A three-dimensional model of the arch was obtained after scanning the dental cast, and the endocrown was designed digitally according to the model. When the design was complete, the endocrown was fabricated with a milling machine. Finally, the endocrown was cemented with self-adhesive resin cement. Results: Over the 9-month follow-up period, no pulpal or periradicular pathology was observed on radiographs. Regarding the crown, the marginal fit was excellent, the anatomical form was protected, and no discoloration occurred. Conclusion: During follow-up, the CAD/CAM PICN block endocrown proved to be a good material for the short- to long-term treatment of a primary tooth. However, more clinical cases and follow-up are required to investigate the long-term effects of antagonistic tooth wear.

This study was carried on to assess the clinical performance of a novel restorative concept consisting in single monolithic lithium disilicate full-contour crowns bonded on computer-aided design/computer-aided manufacturing (CAD/CAM) zirconia complete-arch implant bridges, to overcome the drawbacks related to the chipping of porcelain fused to zirconia restorations. Sixteen patients received 18 implant-supported hybrid screw-cement-retained complete-arch restorations, consisting of single monolithic lithium disilicate full-contour crowns bonded on CAD/CAM zirconia frameworks. The restorations were supported by 4–8 implants. All patients were followed up for at least 3 years on function (range 36 to 60 months, mean 49.3 months). Clinical controls were scheduled every 4 months. The outcomes were implant and prosthetic survival and success rates, any complications, patient satisfaction, and soft tissue parameters. No dropouts occurred. The overall implant and prosthesis survival rates were 100%. One of 18 restorations (1 of 236 dental units) showed a chip-off fracture of the veneering ceramic that was polished intraorally without any additional treatment, scoring a cumulative prosthetic success rate of 100%, according to the California Dental Association index. All patients were functionally and esthetically highly satisfied with their restorations. Successful soft tissue parameters were found around all implants. Single monolithic lithium disilicate full-contour crowns, bonded on CAD/CAM screw-retained complete-arch zirconia frameworks, showed favorable preliminary outcomes with medium-term follow-up. However, randomized controlled studies of this technique are required for further conclusive recommendations.

Processing Errors

There has been an increase in the incidence of complete edentulism among the elder patients. Complete dentures are the most common and preferred treatment of choice. Complete dentures help in masticatory function and restore the facial shape of the edentulous patients. Fabrication of the complete dentures is, therefore, a very important task for the clinician to ensure patient satisfaction. Errors may occur during the denture fabrication and these are called processing errors. It is a multifactorial process. The aim of the survey is to study the errors that occur during processing of a complete denture. It is a questionnaire based study conducted with a batch of 100 dental students. The questionnaire consisted of 16 questions focused on different fabrication techniques, timing, materials used, etc. by various students. The data collected was represented statistically and discussed. Dough technique was the most preferred method adopted by 39% of the students. Shorter curing cycles produced less defects, but majority of the students used longer cycles (41%). Most of them reported fractures (16%) and microporosities (11%) as defects. We can conclude that there are a few areas of error during the processing of dentures by the dental students. The incidence of these errors, however appears to be low. There is a scope for CAD/CAM complete dentures in the future to eliminate the possibilities of errors.

Edentulism has been a severe public health problem in industrialized countries due to aging and poor oral care. Design and fabrication of the complete dentures are mainly using conventional methods involving an enormous series of clinical and laboratory procedures. Edentulous patients have to make several visits to the clinic for the traditional fabrication of denture. Now the unceasing developments occur over several years. Present-day technological innovations allow the use of various systems with computer‑aided design/computer‑aided manufacture (CAD/CAM) technology to produce complete dentures has seen exponential growth. There are different manufacturing techniques of CAD-CAM complete denture like AvaDent, Wieland digital denture, Baltic denture, DENTC system. CAD-CAM technology requires only two appointments for the patient to get their complete removable denture. A reduction in clinical chair time also shortens the cost of care. The improved fit of the denture was because of fewer processing errors. It simplifies the re-manufacturing of lost/broken prostheses due to the digital storage of denture data. The pre-polymerized acrylic resin used by manufacturers for the fabrication of a denture base delivers excellent fit and strength when compared to conventionally processed bases. It doesnt show any polymerization shrinkage as there is a less residual monomer. Hence, it reduces the potential infections as fewer candida albicans attach to the denture bases. The motive of this article is to highlights the benefits of CAD-CAM technology over conventional denture fabrication.

Advancements in ceramics technology and in computer-aided design/computer-aided manufacturing (CAD/CAM) systems, have led to the technological abilities to produce single all-ceramic crowns with high biocompatibility, esthetics, and optimal mechanical properties. However, there is no information regarding the use of this technique in children. Case report:Treatment of extensive crown fractures on an 11 years old patient using a chairside CAD/CAM technology. The teeth were scanned and the restorations were fabricated using the manufacturing unit of the CAD/CAM system and glazed to the appropriate tooth color. At a follow up visits the restorations kept their strength and esthetic appearance (one year follow up). Conclusion: The digital restoration treatment is especially suitable for treating children with dental trauma. It has the advantage of better esthetic, functional and durable results compering to conventional restorations, and it often requires only a single session.
