“… 39 In most model experiments, devices such as universal testers, which can produce a uniform force, are used to prevent any change in the fit during the restoration cementation process. 40 However, in this study, the model experiments and clinical trials were conducted in the same condition. To simulate the restoration cementation process in the clinical setting, finger pressure was applied to the restoration.…”

PURPOSEThe purpose of this study was to compare the fit of cast gold crowns fabricated from the conventional and the digital impression technique.MATERIALS AND METHODSArtificial tooth in a master model and abutment teeth in ten patients were restored with cast gold crowns fabricated from the digital and the conventional impression technique. The forty silicone replicas were cut in three sections; each section was evaluated in nine points. The measurement was carried out by using a measuring microscope and I-Soultion. Data from the silicone replica were analyzed and all tests were performed with α-level of 0.05.RESULTS1. The average gaps of cast gold crowns fabricated from the digital impression technique were larger than those of the conventional impression technique significantly. 2. In marginal and internal axial gap of cast gold crowns, no statistical differences were found between the two impression techniques. 3. The internal occlusal gaps of cast gold crowns fabricated from the digital impression technique were larger than those of the conventional impression technique significantly.CONCLUSIONBoth prostheses presented clinically acceptable results with comparing the fit. The prostheses fabricated from the digital impression technique showed more gaps, in respect of occlusal surface.

“…This prognosis depends on many variables which include geometry of the preparation, fit of the restoration, type of the luting agent used, and periodontal condition of the abutment teeth. [ 6 7 8 9 ] Many investigators have stated that three major factors affect wetting, namely, surface free energy, surface topography of the adherent, and the viscosity of the liquid, of which the influence of surface topography was the least understood. [ 9 10 ] Evidence suggests that enhancing the surface area and wetting improves the bonding considerably.…”

Context: Welded diamond and vacuum diffusion technology (WDVDT) burs in comparison to electroplated burs claim to approach the solution of dental hard tissues by increased cutting efficiency, decreasing the overheating of oral tissues and thus reducing the microcracks on the prepared tooth surface. Aims: This study aimed to evaluate the cutting efficiency of two different rotary diamond burs used for tooth preparation with their repeated usage on the surface changes of the prepared tooth. Settings and Design: This in vitro comparative study evaluated the cutting efficiency and surface changes of the teeth prepared with conventional electroplated burs and WDVDT burs. Subjects and Methods: Thirty freshly extracted, healthy, noncarious human premolars were divided into Group A and Group B with 15 each, and were further subdivided into three subgroups depending on the different usage intervals as first, fifth, and tenth (A1–A3 and B1–B3). The surface of each prepared specimen was evaluated quantitatively using a surface profilometer, and qualitative analysis was done using a scanning electron microscope. Statistical Analysis Used: Two-way ANOVA and Turkey's multiple post hoc tests were used. Results: The mean surface roughness of Groups A1, A2, and A3 was 1.50 ± 0.40, 2.39 ± 0.39, and 2.65 ± 0.65 Ra, respectively. The mean surface roughness of Groups B1, B2, and B3 was 0.76 ± 0.23, 0.92 ± 0.10, and 1.24 ± 0.07 Ra, respectively. The mean surface roughness of the prepared tooth surface was significantly higher in Group A and its subgroups when compared to that of Group B and its subgroups. Conclusions: The study results showed that surface roughness was considerably lesser and also had less wear and increased cutting efficiency of tooth preparations using burs made with WDVDT compared to the preparations using conventional electroplated burs.

“…A superioridade destes cimentos em relação aos de fosfato de zinco e de ionômero de vidro, foi relatada por Gorodovsky & Zidan 13 (1992). Entretanto, as principais desvantagens dos cimentos resinosos são a maior espessura de película e a sensibilidade pósoperatória 6,10 .…”

A influência de quatro agentes cimentantes foram avaliados na resistência à remoção, por tração, de coroas totais metálicas fundidas fixadas sobre preparos em dentina. Vinte e oito molares recém-extraídos foram preparados para coroas totais, com as respectivas peças protéticas sendo fundidas com liga de paládio-prata (Pors-on 4 - Degussa). Os corpos- de-prova foram divididos em quatro grupos de sete unidades cada e as coroas totais fixadas nos grupos 1, 2, 3 e 4, respectivamente, com os cimentos de fosfato de zinco (Cimento de Zinco - SS White), de ionômero de vidro convencional (Ketac Cem - ESPE), de ionômero de vidro modificado por resina (Vitremer - 3M) e resinoso com adesivo (Cimento de Resina - Scotchbond Multi-Uso Plus - 3M). Após 24 horas, os espécimes foram submetidos a 500 ciclos entre 5 e 55 oC e as coroas aos ensaios de tração. Os resultados (kgf), analisados por ANOVA e teste de Tukey (p < 0,05), foram: grupo 1: 16,70; grupo 2: 39,26; grupo 3: 34,91; grupo 4: 75,58. O cimento resinoso com adesivo (Cimento de Resina - Scotchbond Multi-Uso Plus - 3M) (grupo 4) proporcionou resistência retentiva estatisticamente superior à dos demais cimentos. Os cimentos de ionômero de vidro convencional (Ketac Cem – ESPE) (Grupo 2) e modificado por resina (Vitremer – 3M) (grupo 3) proporcionaram resistências estatisticamente similares e superiores à do fosfato de zinco (Cimento de Zinco - SS White) (grupo 1).
