Background: All disciplines of dentistry require that clinicians assess the articulation of the teeth/prosthesis with respect to simultaneous contacts, bite force and timing.Aim: This article intends to describe the advantages and limitations of the data acquired when using a digital occlusal analysis as a dynamic occlusal indicator.Methodology: A search of the literature was completed (Medline, PubMed) using the keywords occlusion, occlusal registration, computerized occlusal analysis and T-Scan for dental.Results: According to the evidence available, the digital occlusal analysis system is the only occlusal indicator that demonstrates the ability to provide quantifiable force and time variance in a real-time window from the initial tooth contact into maximum intercuspation.Conclusion: The reported advantages to accurately indicate occlusal contacts make the digital occlusal analysis system a better occlusal indicator when compared with other non-digital convention indicator materials available.
Introduction - Thermoplastic polymers have many potential uses in medicine and dentistry as an alternative to the commonly used titanium. Since the 1980s, polyaryletherketones (PAEKs) have been increasingly employed as biomaterials for trauma, orthopedic, and spinal implants. Due to several advantages of these materials, metal-free restorations are performing an important role in current medical therapies. PEEK is biologically inert and various surface modifications are given to increase its osseointegration potential of PEEK, Acid etching is the most simple and cost effective method of treatment. The aim of this study is to evaluate the surface roughness and wettability of 2 different acid etching techniques of PEEK samples - Magnetic stirring and ultrasonic. Material and methods - PEEK samples thicknesses of 2 mm and diameters of 15 mm was used in the study and the sulfonation procedure was done magnetically and ultrasonically for 6 mins and samples were rinsed with acetone for 10 mins, washed with deionized water for 10 mins and finally dried at 37°C. The results of the study were subjected to statistical analysis in SPSS software version 23.0. Independent t test was performed for the parameters. Results - when comparing 2 groups magnetic stirred sulfonated PEEK (MSPEEK) and Ultrasonic PEEK (USPEEK) results showed statistically significant difference present. (P < 0.05) in surface roughness and in wettability no significant difference is seen (P > 0.05). Conclusion - The literature suggests that PEEK offers an alternative to titanium, especially in cases of orthopedics and trauma. Its properties make it an interesting material in Dental implantology to be performed with CAD-CAM. Further studies are required to obtain sufficient scientific evidence to enable its uses as a permanent material.
Introduction: Thermoplastic polymers have many potential uses in medicine and dentistry as an alternative to the commonly used titanium. Due to several advantages of these materials, metal-free restorations are performing an important role in current medical therapies. The aim of this review was to evaluate Polyetheretherketone (PEEK) as an alternative material to titanium in dental clinical cases. Methods: Original scientific articles published in Medline-Pubmed database were electronically searched to accomplish the objectives of the study. Only articles published in English were included from 2000 to present using a variety of keywords in combination. The studies relevant to our review were analysed and compared. Conclusions: The literature suggests that PEEK offers an alternative to titanium, especially in cases of orthopaedics and trauma. Its properties make it an interesting material in Dental implantology to be performed with CAD-CAM. Further studies are required to obtain sufficient scientific evidence to enable its uses as a permanent material.
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.
