A Systematic Review on Maxillofacial Prosthesis with Respect to Their Color Stability.

The aim of this systematic review was to identify and analyze the findings of various studies that analyzed the changes in the color stability of maxillofacial prosthetic materials after the addition of various colorants and nanoparticles and assess the change in color after being subjected to either natural or artificial accelerated aging as well as outdoor aging. This systematic review was conducted in accordance with the guidelines of transparent reporting of systematic reviews and meta-analysis (PRISMA Statement). The primary objective of this systematic review was to evaluate the color stability of maxillofacial prosthesis. The secondary objective was to assess the effect of various colorants; pigments; opacifiers; UV absorbers-such as inorganic colorants (dry earth pigments); metal oxides; and organic colorants. The time period of the included studies extended from 2013 to 2023. Electronic database search identified a total of 217 studies. Ten studies were included to meet the research question. All 10 included studies analyzed the effect of various colorants and their exposure to various aging and weathering conditions. It was found that various pigments and nanoparticles had an effect on the color stability. Also weathering and aging conditions had a direct effect on the color stability as well. In terms of disinfection, although there was not much color difference observed, highest change in color stability was observed when rubbing or brushing of the prosthesis was carried out. In conclusion, the color stability of maxillofacial prosthetics is a critical factor that influences both patient satisfaction and the overall cosmetic look. The potential of pigments and nanoparticles to enhance the color stability of silicone-based maxillofacial prosthesis has received much research. By avoiding color fading and discoloration brought on by environmental variables including UV radiation, aging, and chemical exposure, the inclusion of various pigments and nanoparticles has been demonstrated to improve the color stability of silicone maxillofacial prostheses.

Assessment of Knowledge on Implant Abutment and Platform Switching among Dental Specialists Practicing Implantology.

Implant abutment connection has proven to have a significant impact on the success of the prosthetic rehabilitation for an implant-supported restoration. This connection not only provides the base on which the restoration is supported but also maintains the integrity of the hard and the soft tissues surrounding the implant. A wide range of implants and their implant abutments are now widely available in the market. Such a wide range would undoubtedly put the clinician in a quandary when it comes to selecting an acceptable abutment, one that is scientifically based and also has a high clinical rate of success. As a result, this study is a straightforward attempt to assess the knowledge of the dental specialists practicing implantology on the areas of implant abutment connections as well as platform switching. The aim of this study was to assess the knowledge on various implant abutment and platform switching among various dental specialists practicing implantology. An online multiple-choice questionnaire based survey was circulated amongst a total of 100 dental specialists with questions assessing their knowledge about implant-abutment connections, platform switching and its significance. Although the degree of information about implant-abutment connection and platform switching appears to be appropriate among various dental specialists practicing implantology, there is a dearth of understanding regarding the mechanical, biological and technical considerations. With the advent of various implant manufacturer and their production of implants as well as their components, the clinicians are undoubtedly put in a quandary when it comes to selecting an acceptable abutment, one that is scientifically based and also has a high clinical rate of success. Therefore, more light must be thrown not only on the surgical aspects of implant dentistry, but also on the prosthetic rehabilitation and its components, in order to ensure clinical success in terms of restoring a patient's function as well as aesthetic.

A Literature Review on Implant Abutment Types, Materials, and Fabrication Processes.

Dental implantology has made great strides since Dr. Brånemark introduced it to the world of dentistry. In terms of materials and fabrication processes, a wide range of implants and their implant abutments are now widely available in the market. Such a wide range would undoubtedly put the clinician in a quandary when it comes to selecting an acceptable abutment, one that is scientifically based and also has a high clinical rate of success. As a result, this literature review is a straightforward attempt to shed light on the wide range of implant-abutment types, materials and fabrications that are now easily accessible on the market, as well as offer an overview of each specific type to avoid further dilemma for its clinical intent.
