Customized Zirconia Crown in Pediatric Dentistry From Concept to Reality (original) (raw)

Avicenna Journal of Dental Research

Catering a tooth-colored restoration in a single sitting is the fundamental objective of chairside digital dentistry with computer-aided design/computer-assisted manufacturing (CAD/CAM) technology, which became a legitimate reality with the initiation of ceramic reconstruction (CEREC) workflow. CAD/CAM dentistry has evolved through an amalgamation of diverse software and hardware upgrades since its launch to a viable chairside technology that allows pediatric dentists to treat patients in a single visit. Nowadays, CAD/CAM of dental restorations has become an ingrained fabrication process, especially for zirconium restorations. In this report, we have presented three cases to exemplify the clinical use of chairside digital dentistry (i.e., CEREC workflow) for the fabrication of a customized zirconium restoration in a single sitting to restore form, function, and occlusion for grossly decayed and decalcified primary molars, as well as esthetics for primary anterior teeth with utmost c...

Full-mouth reconstruction with Implant and Tooth-supported Zirconia Restorations in a Digital Workflow

European Annals of Dental Sciences, 2021

Zirconia has become a popular restorative material regarding the mechanical and biocompatibility advantages. Monolithic and translucent forms of zirconia advanced the aesthetics of this material, making it the material of choice for both tooth- and implant- supported restorations. Also, digital fabrication of zirconia not only enables accurate restorations but also provides time efficiency. The present case report demonstrates the rehabilitation of a patient who has generalized tooth wear with implant- and tooth supported monolithic zirconia restorations with buccal veneers in a newly established occlusal vertical dimension. The treatment process was completed in a digital workflow as the impressions were taken with a powder-free intraoral scanner and the digital data were send to the dental laboratory to fabricate the restorations. Monolithic zirconia restorations with buccal feldspathic veneers were completed without any adjustments in only two appointments. The patient was satisf...

Feasibility of 3-Dimensional Visual Guides for Preparing Pediatric Zirconia Crowns: An In Vitro Study

International Journal of Environmental Research and Public Health

This study evaluated the feasibility of a tooth preparation guide for prefabricated zirconia crowns (PZCs). Three-dimensional surface data for PZCs of the left maxillary primary first molar and left mandibular primary second molar were obtained using a model scanner. The tooth preparation data were digitally designed to harmonize with the adjacent teeth on the mixed dentition model and visualized using a color-coded map, which presents the required amount of tooth reduction. Twenty participants were recruited for preparing teeth with and without using the tooth preparation guide. The following three parameters were evaluated: tooth preparation time, harmony score, and amount of tooth reduction. The preparation time when using the guide was significantly reduced (p < 0.05), and a significant difference was observed in the harmony scores for the maxillary primary first molar preparation. Furthermore, the amount of tooth reduction was significantly different for both maxillary and m...

Clinical Outcomes of Monolithic Zirconia Crowns with CAD/CAM Technology. A 1-Year Follow-Up Prospective Clinical Study of 65 Patients

International Journal of Environmental Research and Public Health

Aim/Purpose: The primary aim of this study was to examine the clinical performance of posterior monolithic single crowns in terms of failure or complications and the secondary aim was to assess the quality of these restorations according to the United States Public Health Service (USPHS) criteria. Methods: Ιn a private dental clinic, 65 patients with need of posterior crowns were restored with monolithic zirconia crowns. All the restorations were evaluated 6 and 12 months after their cementation. The modified United States Public Health Service (USPHS) criteria and periodontal parameters were applied for the clinical evaluation of the crowns. Restorations with Alpha or Bravo rating were considered a success. Results: Descriptive statistics and nonparametric tests were used for statistical analysis. Sixty-five patients (mean age: 49.52) were restored with 65 monolithic zirconia crowns. No fracture of the restorations was recorded. The overall success rate was 98.5%. The clinical qual...
