“…The increased pursuit for perfect dental restorations has led to the development of new dental ceramics competing in strength, durability and aesthetic capabilities. 1,2 The availability of a large number of products makes the choice of the best possible material for a particular case difficult for clinicians because long-term performance of recent materials remains an open question. Therefore, more laboratory simulations and long-term clinical studies are needed to ensure favorable mechanical behavior and to estimate clinical performance of newly introduced restorative materials.…”

Objective This study investigates the influence of the most commonly used indenter materials on fatigue survival and fracture resistance of zirconia crowns. Materials and Methods A total of 40 zirconia crowns were prepared using computer-aided design (CAD)/computer-aided manufacturing (CAM) technology: 30 crowns were divided into three experimental groups of 10 specimens and the last 10 specimens acted as the control group. The experimental groups were subjected to chewing simulation with simultaneous thermocycling. Three indenter materials (steatite ceramic, stainless steel, and tungsten carbide) with identical diameter were used to load the specimens. All crowns were then subjected to single load to fracture test in universal testing machine. Load was applied vertically with a crosshead speed of 1 mm/min until failure, and fracture load was recorded. Statistical Analysis Normal distribution of data was confirmed using the Shapiro–Wilk test. Descriptive statistics including means and standard deviations were determined for all groups. Differences between groups were tested using Dunnett’s test and paired sample t-test. Results Chewing simulation for 1.2 million cycles resulted in 100% survival. The highest mean fracture load was recorded for the control group and the lowest one was for the group fatigued with stainless steel indenter. Chewing simulation statistically significantly (p < 0.05) reduced the mean fracture load of the crowns fatigued with stainless steel and steatite ceramic indenter. However, the mean fracture load for the crowns fatigued with tungsten carbide was not significantly different from that of the control group. Conclusion Steatite ceramic and stainless steel indenters produced close results and significantly reduced fracture load of zirconia crowns. However, tungsten carbide indenter caused nonsignificant reduction in the fracture load of zirconia crowns.

At present, science has provided us with a tool that facilitates the planning for the dentist of an aesthetic and functional rehabilitation work and that also allows the patient to visualize how his work would be in the mouth. In this way the patient has a clearer picture of what he can expect from his treatment and feel completely satisfied. These tools are the different software systems that digitally design a smile. The importance of this literature review work is to inform professionals of the technological advances that are available to us, to facilitate the work of the dentist and obtain, every day, more happy patients with the result of their treatments. The main objective of this article is to make known that by using digital systems to design a smile, we can facilitate the visualization of the patient towards what their treatment will be, and also help the professional with the planning of treatment with functional restorations and aesthetic The present literature review work has a qualitative retrospective cross-sectional approach of non-experimental design. At present, the professional could use the digital design system to facilitate the way in which the patient observes his smile design and its consequent dental treatment so as not to create false expectations. In this way the dentist can choose what type of software to use, within the brands that are in the market.

“…Due to permanent improvements in the material properties and high aesthetic demands of patients, allceramics has become indispensable in everyday clinical practice as a material for restorations [6]. In light of the growing demand for highly aesthetic restorations, it is the dentist's task to both keep up to date with the latest scienti c research and to develop scienti c evidence to support the clinical application of materials [7,8]. Special attention has been paid to zirconium dioxide as a dental material due to its superior mechanical properties, high biocompatibility, and natural appearance [9][10][11].…”

BackgroundThe abrasion behavior of various ceramics is rarely investigated, though it is relevant for the clinical success of such restorations. The aim of this in vivo study was to evaluate the wear of glass-ceramic-veneered zirconium oxide frameworks over a period of 10 years.MethodsThe abrasive behavior of the restorations was examined in a total of 15 patients after a period of 3, 5, and 10 years using plaster models, which were then subjected to a scanning process on the Atos II industrial scanner and digitized for three-dimensional evaluation of the abrasion by the corresponding software (ATOS Professional 7.6). The individual post-examination models were compared to the baseline model and deviations calculated in the sense of the largest, punctual loss of material in millimeters ("minimal distance"), the average abrasion in millimeters ("mean distance"), and the volume decrease in cubic millimeters ("integrated distance"). Statistical analyses were performed using the Wilcoxon sign rank test or mixed regression models. Multiple testing was considered by Benjamini-Hochberg correction. The significance level was set at 0.05.ResultsWe found steadily increasing wear of the ceramic. The average volume decrease was significant (P < 0.001) at 3 years and 10 years (-3.25 mm3 and − 8.11 mm3, respectively).ConclusionsDespite the increasing wear of the glass-ceramic-veneered zirconium oxide frameworks in this study, the use of this class of materials can be regarded as clinically acceptable.This study is registered in DRKS - German Clinical Trials Registerwith the Register number 00021743
