Customized Zirconia Crown in Pediatric Dentistry From Concept to Reality
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...
Applicability of Zirconia-Prefabricated Crowns in Children with Primary Dentition
Revista de Chimie
Zirconia dioxide represents the current alternative in restoring primary teeth, being the most promising restorative material through its properties that offer. Zirconia crowns main properties are its aesthetics, resistance to fracture and compression, biocompatibility, alternative for the patients that are allergic to Ni-Cr. This cross-sectional study pointed out the correlations between the rate of applicability of the Ni-Cr crowns and the ZrO2 crowns, as well as the range of applicability of the ZrO2 crowns on temporary teeth among practitioners. The method of choice in the case of extensive carious lesions treatment on the primary teeth was the restoration using filling materials. From the 33,2% of the dentists who decide to apply a pedodontics crown, 75% use the Ni-Cr crowns, and only 25% of them choose the ZrO2 crown (p[0.0001). The applicability of ZrO2 crowns in pediatric dentistry is quite reduced, despite their physiognomic advantages, their excessive cost can also be an i...
Survey on the Use of Zirconia Crowns in Pediatric Population among General Dental Practitioners
Dental Journal of Advance Studies
Background Pediatric zirconia crowns are metal free and more aesthetic and compatible option available for the full coronal coverage of the affected primary dentition. These crowns are not new to pediatric dentistry but usage is limited. Materials and Methods A cross-sectional, descriptive survey was conducted among 200 general dental practitioners and were requested to answer a questionnaire. The questions were framed regarding the knowledge of pediatric dental procedures, aesthetic replacement in case of full coverage restorations, and zirconia crown's features and its use in the practice, and were evaluated. Results Results were based on features of zirconia crowns according to which 81.5% participants mentioned them as stainless steel alternative and 62% as biocompatible material. Clinical aspects evaluated the amount of occlusal reduction in case of zirconia crown tooth preparation as 1 to 1.5 mm by 72.5% of the participants. Appropriate type of finish line and type of marg...
Case Series on Personalized Pediatric Posterior Zirconia Crowns
International Journal of Pedodontic Rehabilitation
Pediatric dentists must comprehend children's aesthetic perception because kids are increasingly aware of their own and other children's appearance. Many aesthetic restorations are available on the market, including open-faced stainless-steel crowns, pre-veneered stainless-steel crowns, strip crowns, and polycarbonate crowns, but each has its own drawbacks. Prefabricated zirconia crowns are a new trend among pediatric dentists for restoring carious, damaged, and malformed primary molars and anteriors. Customized zirconia crowns, on the other hand, may be able to overcome the limitations of prefabricated crowns in certain situations, particularly molars, resulting in excellent aesthetics and longevity. Our case series illustrates the use and performance of personalized zirconia crowns in a variety of challenging clinical circumstances.

Background Providing restorations to anterior teeth in children is a challenging task due to the need for high esthetics, strength, and durability. This study was done to compare prefabricated primary zirconia with resin composite strip crowns on primary maxillary central and lateral incisors with regards to gingival health, plaque accumulation, recurrent caries, restoration failure, and opposing teeth wear over a period of 3, 6 and 12 months. Methods Children attending the King Abdulaziz University, Faculty of Dentistry (KAUFD) clinics who needed restorations were screened for inclusion criteria. A total of 120 teeth were treated; 60 with zirconia and 60 with strip crowns. Randomization was done by simple random allocation using SPSS software version 20.0 (Armonk, NY; IBM Corp.). A simple descriptive statistic was used for analysis by Wilcoxon Signed-Rank test and Chi-square test. Level of significance was set at (α = 0.05) and level of confidence at (95%). The presented research w...
