RESUMEN
Objectives: Accurate impressions are essential in fabricating dental restorations and fixed dental prostheses. During the last decade, digital impression systems have improved substantially. The objective of this narrative review is to discuss the recent research on intraoral scanners with regards to it's technology, accuracy and applications for fabrication of dental restorations and fixed dental prostheses. Materials and methods: A search strategy was performed in MEDLINE/PubMed, Scopus and Google Scholar with keywords - intraoral scanners, accuracy, applications, dentistry. Results: 395 articles were retrieved. After hand search a total of 415 articles were identified. Ultimately, 30 articles were selected and summarized and discussed as they met the selection criteria. Conclusion: Within the scope of this review, reported literature showed that digital intra-oral impressions have presented an achievement in the dental market as they reduce time required and simplify the clinical procedures with better communication with the technician and the patient. The current intraoral scanners (IOS) are sufficiently accurate for capturing impressions for fabrication of prosthetic restorations (inlays/onlays, copings and frameworks, single crowns and fixed partial dentures) on both natural teeth and implants; in addition, they can be used for smile design, and to fabricate posts and cores, removable partial prostheses, obturators, orthodontic aligners and custom made devices. The use of IOS in long-span restorations with natural teeth or implants is still a challenge.
RESUMEN
Lately esthetic rehabilitation has come to be a demanding treatment as a way to correct malposed as well as missing anterior dentition, the advent of creating an esthetic smile has become a part of routine dental practice. An attractive or appealing smile sincerely enhances the recognition of an individual in our society with the aid of enhancing the initial impact in interpersonal relationships. Any esthetic correction calls for right expertise and knowledge. Such rehabilitation can be achieved successfully with the aid of numerous treatment approaches. Orthodontic treatment is one of the most conservative approach for such cases but it is not an acceptable treatment option for most of the patients due to various reasons like long treatment time, financial constraints, appearance during the therapy, and relapse after the treatment. Alternatively, endodontic approach combined with prosthodontics offers a brief, reliable and economic treatment modality for such cases. Placement of implants has also become a treatment of choice for replacement of teeth in esthetic zone with advantages like preservation of unrestored adjacent teeth and halting the resorption of edentulous spaces to provide support for the prosthesis. This case report illustrates the multidisciplinary approach for rehabilitating aesthetics in anterior region.
RESUMEN
Introduction: The demand for metal free restorations may it be fixed or removable has increased manifold in the recent past. BioHPP is one such material that has been introduced recently in the field of prosthodontics. Aim: The aim of this narrative review is to discuss the properties of BioHPP (Biocompatible High Performance Polymer) material and its applications in the field of prosthodontics Materials and Methods: A search strategy was performed on PubMed and Google Scholar with key words: Modified PEEK, BioHPP, Prosthodontic applications. Results: Seventy nine articles were retrieved. After hand search and along with cross reference a total of 84 articles were identified. Ultimately 18 articles were selected and discussed as they met the selection criteria. Conclusion: Within the scope of this review, reported literature showed that BioHPP has proven to be a boon to the field of prosthodontics as a result of its excellent biocompatibility as well as mechanical properties. BioHPP offers a wide range of applications may it be in removable or fixed prosthodontics. With an increase in the number of clinical trials and long term follow up studies, BioHPP might prove to be a material of choice for a variety of prosthodontic applications.
