Resin Nanoceramic CAD/CAM Restoration of the Primary Molar: 3-Year Follow-Up Study

Case Series on Personalized Pediatric Posterior Zirconia Crowns

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.

Digitainers-Digital Space Maintainers: A Review

To summarize the limitations of commonly used space maintainers (SMs) and provide an insight into the field's technological advances to overcome them, this review was conducted. With the rapid advancement of digital technologies, there is always something new to learn while also redefining the current fads. Digital workflow is not a new concept in dentistry, but it has only just begun to be used in pediatric dentistry. The curiosity to explore has led to the development of digital devices as SMs. They appear potential for usage in children because of their impressive advantages of precision, comfort, and a time-saving approach. This workflow helps lessen fear and improve children's cooperation and enthusiasm for dental appointments by cutting down on chairside time and shortening procedures.

Clinical outcomes of single crown restorations fabricated with resin-based CAD/CAM materials

Computer-aided design/computer-aided manufacturing (CAD/CAM) restorative materials have been widely used owing to a number of advantages, including stable quality of the materials, lower costs, and time-saving factors. Resin-based CAD/CAM materials for definitive restorations are classified into two groups: dispersed nanoparticle-filled composite resin and polymer-infiltrated-ceramic-network materials. Resin-based CAD/CAM materials have been applied to single crown restorations as a monolithic structure for the posterior region. In addition, resin-based CAD/CAM restorations have been applied recently for the anterior area. This literature review summarizes clinical outcomes, such as survival rates and clinical complications of single crown restorations fabricated with resin-based CAD/CAM materials.

Computer-aided Design and Manufacturing Crown on Primary Molars: An Innovative Case Report

Aim

Crowns are applicable on primary teeth with extensive caries, cervical decalcification, developmental defects, interproximal caries extending beyond line angles, and following pulpotomy or pulpectomy.

Background

Until now, prefabricated crowns, i.e., stainless-steel crowns (SSCs), pre-veneered SSC, and all ceramic/porcelain/zirconia crowns have been available in a range of sizes to match the first and the second primary molar teeth.

Case description

This case report illustrates a clinical use of computer-aided design and manufacturing technology (CAD/CAM) for the fabrication of a crown for a decayed primary molar using a study model as a reference. The material used was a hybrid ceramic CAD/CAM block.

Conclusion

This approach has the advantage of the customization of the abutment tooth in contrast to the previously mentioned prefabricated options.
