The ability to mimic the optical characteristics of enamel and dentin, the excellent biocompatibility and the chemical durability of dental ceramics are the reason reasons why this topic is considered of great importance in dentistry. The aim of this study was to highlight the differences during the process of manufacturing anterior esthetic restorations, i.e. the proper selection of color shades of dental ceramics and their correct deposition.Techniques for performing aesthetic ceramic restorations are influenced by the experience of the dental technician and their skills in realizing the restoration, which should be as little complicated, even if the dental ceramic powders has coded shades of color. Some dental technicians prefer their own color labels in order to facilitate their work and to modify or to highlight some effects of the powders, during the dental ceramics build-up. Naturalness of eight anterior restorations was obtained by alternating the opalescent base layer of the dental ceramic and the fluorescence of crystalline layers subsequently applied over opaque. Different translucent type of ceramic layers was used in order to create the true aspect of the incisal area, with a natural halo appearance. The increasing expectations of the patients in aesthetic restoration of anterior area of dental arches demand a complex build-up of the porcelain layers and this technique requires that the dental technician to possess special skills for obtaining a successful result.

Ceramic Restorations

During fabrication of bonded ceramic restorations, cervical adaptation, occlusal adjustment and final finishing/polishing are procedures to be performed at the dental office after adhesive cementation. Final adjustments may result in loss of ceramic glaze, which requires new polishing of the ceramic surface, with special attention for selection of adequate materials and instruments. The purpose of this study was to evaluate the efficiency of different vehicles associated with diamond pastes indicated for dental ceramic polishing. Two polishing pastes (Crystar Paste and Diamond Excell) associated with four vehicles (rubber cup, Robinson bristle brush, felt wheel and buff disc) were evaluated. Disc-shaped specimens were fabricated from Ceramco II dental ceramic. Surface roughness means (Ra) of the ceramic specimens were determined with a rugosimeter. Data were analyzed statistically by two-way ANOVA and Tukey's test at 5% significance level. There was no statistically significant difference (p>0.01) between the polishing pastes. However, there were statistically significant differences (p<0.01) among the tested vehicles. Vehicle-paste interaction showed statistically significant difference (p<0.05) as well. It may be concluded that: 1) Robinson bristle brush, felt wheel and buff disc were efficient vehicles to be used in association with a diamond polishing paste; 2) The use of rubber cup as a vehicle showed poor efficiency for mechanical polishing of the ceramic surfaces; 3) Both pastes provided similar and efficient polishing and may be recommended for use with an appropriated vehicle.

For endodontically treated lateral teeth, direct restoration made of photocomposites is most often used, and indirect ceramic restoration appears to be more promising, for which, however, additional retention is required. The aim of the study was the clinical evaluation of direct photocomposite and indirect ceramic restorations of endodontically treated lateral teeth. The object and methods of the research. We examined 118 people aged from 24 to 53 years, in whom 249 lateral teeth with cavities were endodontically treated according to the 2nd class by Black. Group 1 included 38 patients (32.2% of the total number of subjects) who underwent direct restoration of 89 molars (35.7% of the total number of restorations) made of photocomposite; 41 patients (34.7%) with 81 indirect ceramic restorations (32.5%) were included in group 2 according to the generally accepted requirements; group 3 consisted of 39 people (33.1%), who underwent 79 indirect ceramic restorations (31.7%) with the formation of cavities with additional retention elements. Direct restorations in the subjects from group 1 were performed with a photocomposite using a 5th generation adhesive system in a layered technique with light polymerization by “soft start”. In the molars of persons from groups 2 and 3, cavities were prepared taking into account the generally accepted requirements, while in the cavities of the molars in patients from group 3, we formed retention elements in dentin in the form of depressions. Intraoral optoelectronic scanner CEREC AC Connect Omnicam, Dentsply Sirona was used for scanning, restorations were modeled in Exocad software and made of ceramic CAD-blocks based on lithium disilicate using an inLab MC X5 assembler, Dentsply Sirona. The restoration was fixed on a self-adhesive composite cement of double hardening. Clinical evaluation of restoration was performed in 18 and 24 months. Impairments and the number of restorations with them were registered. Research results and their discussion. In the period of 18 months, out of 70 direct photocomposite restorations (78.7% of the initial number) in persons of group 1, 2 restorations (2.2%) were partially absent, in 4 restorations (4.5%) anatomical impairments were revealed, in 5 (5.6%) – impairments of the marginal adaptation, in 8 (9.0%) – marginal color, also in 8 cases (9.0%) there were impairments of contact points. All impairments were identified in 12 restorations (13.5%). In patients of 2 groups, in 78 indirect ceramic restorations (96.3%) we revealed a partial destruction and shift of 1 restoration (1.2%), disturbance of an anatomic form – in 2 restorations (2.5%), in 3 restorations (3.7% each) there were defects of marginal adaptation and marginal color, contact points were impaired in 4 cases (4.9%). In total, impairments were detected in 5 restorations (6.2%). In 77 indirect ceramic restorations (97.5%) in patients of group 3, 1 restoration (1.3% each) had impairments of anatomical shape, marginal adaptation and contact points, 2 restorations (2.5%) had marginal color. Impairments pertained to only 2 restorations (2.5%). In 24 months, out of 58 direct restorations (62.5%) of patients in group 1, 3 restorations (3.4%) were partially or completely absent, anatomical impairments were found in 6 restorations (6.7%), and marginal defects were found in 7 (7.9%), marginal color – in 11 (12.4%), 15 contact points (16.9%) were with impairments. The number of direct restorations with impairments was 20 (22.5%). In 77 indirect restorations (90.1%) in persons of the 2nd group, we revealed a partial destruction and displacement of 3 restorations (3.7%), 2 restorations (2.5% each) had impairments of anatomical shape and marginal adaptation, 4 each (4 , 9%) – marginal color and defects of contact points. In total, there were 7 indirect restorations (8.6%) with impairments. In patients of group 3, among 75 indirect restorations (94.9%) 1 restoration (1.3% each) had disturbances of anatomic shape and marginal adaptation, 2 restorations (2.5%) were with marginal coloring, 3 (3.8 %) – with defects of contact points. There were 3 indirect restorations with impairments (3.8%). Conclusion. During both terms with impairments, we detected 32 direct photocomposite restorations (36.0%), 12 indirect ceramic restorations (14.8%) and only 5 indirect ceramic restorations (6.3%) made with additional retention elements.
