ABSTRACT
Retention, stability and support are the most fundamental and basic principles on which the success of an entire denture relies on. However this factor is often compromised in cases of resorption. Residual ridge resorption is the reduction in size of the bony ridge under the mucoperiosteum. The rate of resorption in mandibular arch is at an increased rate as compared to the maxillary arch; but severely atrophic maxillae with large inter-ridge distance often pose a clinical challenge during fabrication of a successful maxillary complete denture because of the increased weight of the denture, retention is compromised. The present article describes a case of a completely edentulous patient who was successfully rehabilitated with a hollow denture where a simple and deviceful technique of fabricating a light-weight maxillary denture. The present article describes a case of a completely edentulous patient who was successfully rehabilitated with a hollow denture where a simple and deviceful technique of fabricating a light-weight maxillary denture was used using the hollow tubing of salivary ejector apparatus to bring the uniform hollowness.
ABSTRACT
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.
ABSTRACT
Objectives: Occlusion is a critical and very important component for the clinical success and longevity of dental implants. This review article focuses on the various aspects of implant protective occlusion. Our scientific literature regarding implant occlusion, particularly in implant-supported fixed dental prostheses remains controversial. Materials and methods: A search strategy was performed in MEDLINE/PubMed, Scopus and Google Scholar with keywords 'implants' and 'occlusion', 'implants' and 'fixed prosthesis, 'implants' and 'fixed dental prostheses', 'implants' and 'partial edentulism', 'implants' and 'complications', 'implants' and 'failures', 'implants' and 'cantilever', 'implants' and 'occlusal load'. Results: 135 articles were retrieved. After hand search a total of 290 articles were identified. Ultimately, 30 articles were selected and summarized and discussed as they met the selection criteria. Conclusion: Most of the available clinical data are controversial. Implant-protected occlusion can be accomplished by decreasing the width of the occlusal table and improving the direction of force. By doing these things, we can minimize overload on bone-implant interfaces and implant prostheses, to maintain an implant load within the physiological limits of individualized occlusion, and ultimately provide long-term stability of implants and implant prostheses. Current clinical practices rely heavily on principles extracted from the natural dentition or removable dental prostheses on complete edentulous patients and on expert opinions.
ABSTRACT
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.
