Background IRRPD offers patients the ability to upgrade their treatment planning to implant-supported-overdentures (ISOs) or implant-supported-fixed-prostheses (ISFPs) through insertion of more implants in the future after the loss of the remaining natural teeth.
BACKGROUND One of the important factors in the success of teeth with endocrown restorations is to achieve minimum values of internal and marginal gap. The purpose of this review article is to explore the information published in the marginal and internal adaptations of zirconia endocrowns. METHODS This review article was conducted using keywords of CAD/CAM, Endocrown and Marginal and internal adaptation in the Medline database. The search range included all relevant articles by the end of 2018. RESULTS The results of this study showed that 12 studies by the end of 2018 examined marginal and internal adaptation of endocrowns. Most studies were conducted in laboratory conditions. A majority of studies, which compared CAD/CAM systems, showed that the compared groups in terms of marginal and internal adaptation of endocrowns were in the clinically acceptable range in most cases. CONCLUSIONS A review of included studies showed that the endocrowns have the same or better marginal and internal adaptation compared to conventional crowns. However, there is a need for further studies with larger sample size and clinical trials in this area.
Congenitally missing teeth and/or hypodontia is a prevalent dental anomaly. There are different treatment options available for these conditions such as space maintenance, restoring the space by resin-bonded-fixed-partial-dentures (RBFPDs), and dental implants. This study addresses the comprehensive treatments for congenitally missing tooth and diastema using interdisciplinary approaches. One patient was treated with small-diameter-implants and the other one was treated using an intraoral scanner to make digital impression and fabricating RBFPDs with CAD/CAM system. Both patients were completely satisfied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
