“…12 These surface modifications are based on roughening the surface and increasing its wettability. [13][14][15][16] Conventional adhesion techniques used for silica-based ceramic (such as etching by hydrofluoric acid) cannot be used for zirconia ceramics, because it fails to achieve adequate surface roughness and will lead to poor bonding strength. 10,[17][18][19] The airborne Al 2 O 3 particle abrasion of zirconia ceramics surface has been found an effective method for achieving durable ceramic-resin bonding.…”

Introduction:In recent years, the use of ceramic base zirconia is considered in dentistry for all ceramic restorations because of its chemical stability, biocompatibility, and good compressive as well as flexural strength. However, due to its chemical stability, there is a challenge with dental bonding. Several studies have been done to improve zirconia bonding but they are not reliable. The purpose of this research is to study the effect of plasma treatment on bonding strength of zirconia. Methods: In this in vitro study, 180 zirconia discs' (thickness was 0.85-0.9 mm) surfaces were processed with plasma of oxygen, argon, air and oxygen-argon combination with 90-10 and 80-20 ratio (n=30 for each group) after being polished by sandblast. Surface modifications were assessed by measuring the contact angle, surface roughness, and topographical evaluations. Cylindrical Panavia f2 resin-cement and Diafill were used for microshear strength bond measurements. The data analysis was performed by SPSS 20.0 software and one-way analysis of variance (ANOVA) and Tukey test as the post hoc. Results: Plasma treatment in all groups significantly reduces contact angle compare with control (P = 0.001). Topographic evaluations revealed coarseness promotion occurred in all plasma treated groups which was significant when compared to control (P < 0.05), except argon plasma treated group that significantly decreased surface roughness (P < 0.05). In all treated groups, microshear bond strength increased, except oxygen treated plasma group which decreased this strength. Air and argon-oxygen combination (both groups) significantly increased microshear bond strength (P < 0.05). Conclusion: According to this research, plasmatic processing with dielectric barrier method in atmospheric pressure can increase zirconia bonding strength.

“…Many recent studies investigated the effect of APA on t-m phase transformation 9,11,52 and its association with the generation of residual compressive stresses, which stated that APA in short term will increase the strength of zirconia, but in long term it could be detrimental to the restoration due to the defects and low-temperature degradation suffered by zirconia. [53][54][55][56] Regarding the residual stress, and if it could be considered as a positive or negative attribute for zirconia after surface treatment, previous studies stated that the hump observed after cutting or surface grinding of TZP ceramics has been related to the formation of orthorhombic or rhombohedral phase 57,58 or lattice distortion.…”

Aim:The aim of this study was to evaluate the effect of different surface treatments on roughness, grain size, and phase transformation of presintered zirconia. Materials and methods:Surface treatments included airborne particle abrasion (APA) before and after sintering with different particles shape, size, and pressure (50 μm Al 2 O 3 , 50 μm glass beads, and ceramic powder). Thirty-five square-shaped presintered yttrium-stabilized tetragonal zirconia polycrystal (Y-TZP) ceramic slabs (Zenostar ZR bridge, Wieland) were prepared (4 mm height × 10 mm width × 10 mm length) and polished with silicon carbide grit papers #800, 1000, 1200, 1500, and 2000 to ensure identical initial roughness. Specimens were divided into five groups according to surface treatment: group I (control): no surface treatment; group II: APA 50 μm Al 2 O 3 after sintering; group III: APA 50 μm Al 2 O 3 particles before sintering; group IV: APA 50 μm glass bead particles before sintering; and group V: APA ceramic powder before sintering. Specimens were analyzed using scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD) analyses, and tested for shear bond strength (SBS). Data were statistically analyzed using one-way analysis of variance (ANOVA) followed by post hoc tests for multiple comparisons Tukey's test (α ≥ 0.05). Results: Air abrasion before sintering significantly increased the surface roughness when compared with groups I and III. The highest tetragonal to monoclinic (t-m) phase transformation (0.07%) was observed in group III, and a reverse transformation was observed in presintered groups (0.01%). Regarding bond strength, there was a significant difference between APA procedures pre-and postsintering. Structural and Morphological Evaluation of Presintered Conclusion:Air abrasion before sintering is a valuable method for increasing surface roughness and SBS. The abrasive particles' size and type used before sintering had a little effect on phase transformation.Clinical significance: Air abrasion before sintering could be supposed to be an alternative surface treatment method to air abrasion after sintering.

“…O grupo das cerâmicas cristalinas ou policristalinas não apresenta fase vítrea, mas uma matriz atômica regular densa que dificulta a propagação de trincas 18 . Por esse motivo, cerâmicas policristalinas são, geralmente, mais resistentes e menos estéticas do que as cerâmicas vítreas, porém, seu processamento é mais complexo, sendo realizado pelo sistema CAD/CAM (Computer-aided design/ Computer-aided manufacturing).…”

“…Por esse motivo, cerâmicas policristalinas são, geralmente, mais resistentes e menos estéticas do que as cerâmicas vítreas, porém, seu processamento é mais complexo, sendo realizado pelo sistema CAD/CAM (Computer-aided design/ Computer-aided manufacturing). Existem várias opções de sistemas cerâmicos formados pela sinterização direta de cristais disponíveis comercialmente, tanto os de alumina (Procera AllCeram, Nobel Biocare) quanto os à base de zircônia (Cercon, Dentsply; LAVA, 3M ESPE; Procera AllZirkon, Nobel Biocare) 4,18 . Em geral, as cerâmicas com alto teor cristalino são mais opacas, se comparadas com as vitrocerâ-micas, assim, são indicadas principalmente como material de infraestrutura sobre o qual uma vitrocerâmica de cobertura é aplicada, para alcançar melhores resultados estéticos 4,18 .…”

“…A fim de melhorar a resistência de união do cimento à superfície cerâmica, são propostas várias estratégias para o tratamento superficial das cerâ-micas odontológicas, desde condicionamento com ácido hidrofluorídrico (HF), seguido de aplicação de silano 8,[13][14][15] , até jateamento com óxido de alumí-nio [16][17][18] , revestimento com partículas modificadas por sílica 18,19 e, mais recentemente, emprego de diferentes tipos de laser [20][21][22] . É importante considerar as características dos cimentos resinosos e sistemas adesivos para que, combinados ao tratamento de superfície, possam proporcionar resultados de resistência adesiva melhorados 23,24 .…”

Objetivo: apresentar uma revisão de literatura sobre os tipos de tratamentos de superfície disponíveis para cimentação adesiva a sistemas cerâmicos. Revisão de literatura: ainda que haja certo consenso na união adesiva às vitro cerâmicas, ainda não há uma unanimidade quanto à adesão de cerâmicas policristalinas de alta resistência. Com base na literatura disponível, para vitrocerâmicas, o tratamento preferencial ainda é o condicionamento com ácido hidrofluorídrico (HF), em concentração e tempo correspondentes a seu conteúdo cristalino, seguido de silanização. Para as policristalinas à base de zircônia, métodos como condicionamento seletivo por infiltração ou revestimento tribo químico com sílica, seguidos de silanização e utilização de primer sou cimentos resinosos contendo monômero MDP, resultaram em altos valores de resistência de união. Considerações finais: vitrocerâmicas são adequadamente tratadas por meio de condicionamento com HF, seguido de silanização. Maiores valores de resistência de união para as cerâmicas policristalinas foram obtidos após tratamento com condicionamento seletivo por infiltração ou silicatização, seguido de silanização, além da utilização de primers ou cimentos resinosos contendo monômero MDP. Porém, são necessários estudos in vitro adicionais para definir a melhor opção de tratamento para tais materiais. Palavras-chave: Cerâmicas. Cimentação. Restauração dentária permanente.
