2. Longevity of metal-ceramic crowns cemented with self-adhesive resin cement: a prospective clinical study
Abstract Resin cements are often used for single crown cementation due to their physical properties. Self-adhesive resin cements gained widespread due to their simplified technique compared to regular resin cement. However, there is lacking clinical evidence about the long-term behavior of this material. The aim of this prospective clinical trial was to asse

3. Effects of coronal substrates and water storage on the microhardness of a resin cement used for luting ceramic crowns
Composite resin and metallic posts are the materials most employed for reconstruction of teeth presenting partial or total destruction of crowns. Resin-based cements have been widely used for cementation of ceramic crowns. The success of cementation depends on the achievement of adequate cement curing. Objectives: To evaluate the microhardness of Variolink

4. Avaliação estrutural e biológica de coroas sobre implante confeccionadas com pilares de zircônia em região estética. / Structural and biological crowns on implant abutments made from zirconia region in aesthetics.
This prospective in vivo study has as main objective to evaluate the structural and biological performance of single-tooth implant supported-zirconia restoration in aesthetic region. Sixteen subjects were selected for the placement of thirty-one implants in aesthetic region. For the sample group fifteen single-tooth implants were fabricated. Zirconia abutmen

5. Internal fit of two all-ceramic systems and metal-ceramic crowns
OBJECTIVES: The aim of this study was to investigate the internal fit (IF) of glass-infiltrated alumina (ICA - In-Ceram Alumina), yttria-stabilized tetragonal zirconia polycrystals (Y-TZP - IPS e.max ZirCAD), and metal-ceramic (MC - Ni-Cr alloy) crowns. MATERIAL AND METHODS: Sixty standardized resin-tooth replicas of a maxillary first molar were produced for

6. Análise da qualidade de polimerização, por meio de testes de microdureza, de um cimento resinoso utilizado na cimentação de coroas totais em preparos com diferentes substratos / Analysis of quality of polymerization of a resin cement used to cement ceramic crowns in differents preparation substrates through microhardness tests
O objetivo deste estudo foi avaliar a microdureza do cimento resinoso Variolink II ( Ivoclar Vivadent, Schaan, Liechtenstein) empregado na cimentação de coroas totais de cerâmica (IPS e.max Press, Ivoclar Vivadent, Schaan, Liechtenstein) em preparos com 3 substratos (dentina, metal e resina composta). Foram utilizados 30 molares distribuídos em 3 grupos

7. Biaxial flexural strength of Turkom-Cera core compared to two other all-ceramic systems
Advances in all-ceramic systems have established predictable means of providing metal-free aesthetic and biocompatible materials. These materials must have sufficient strength to be a practical treatment alternative for the fabrication of crowns and fixed partial dentures. OBJECTIVES: The aim of this study was to compare the biaxial flexural strength of thre

8. Endodontic and prosthetic treatment of teeth with periapical lesions in a 16-year-old-girl
This paper reports the nonsurgical endodontic therapy using calcium hydroxide intracanal dressing and prosthetic treatment of 9 teeth with periapical lesions in a 16-year-old female patient. The periodontal treatment plan included oral hygiene instructions, mechanical debridement and gingivectomy in the maxillary incisors to improve gingival contouring. Root

9. Evaluation of abutment and perimplantar region deformation of implant-supported screwed prostheses: an study using strain gauges / Avaliação da deformação do intermediário e região perimplantar de próteses implanto-suportada unitárias parafusada: estudo através da extensometria
The dental implant depends on the supporting bone for its stability and functional longevity. Mechanical behavior and trabecular bone structure affect the interface with the implant. Such knowledge may provide a basis for improvements in the current implant function and design, decreasing bone crest resorption and failure at bone-implant junction. Adequate q

10. Comparative study of the compressive strength between aluminized porcelain crown infiltrated for glass and crown of feldspática porcelain and hígido permanent natural tooth / Estudo comparativo da resistência à compressão entre coroa de porcelana aluminizada infiltrada por vidro, coroa de porcelana feldspática e dentes permanentes hígidos
Este estudo objetivou avaliar a resistência máxima às forças de compressão entre dois grupos diferentes de coroas em porcelanas livres de metal cimentadas sobre dentes naturais e um grupo formado por dentes caninos naturais hígidos e comparar os resultados obtidos com os de (Chaves, 2001), em seu trabalho de Doutorado onde também se avaliou a resistê

11. Evaluation of failure mode of ceramic crowns with and without framework design modification. / Avaliação do modo de falha de coroas cerâmicas com e sem alteração do desenho das infraestruturas
Ceramic crowns have been widely used, however, problems related to brittle fracture of these materials persist, especially in the posterior area. The present study tested the null hypothesis that there were no differences in fatigue resistance related to the framework design as well as to the materials used. One maxillary molar was prepared, reproducing the

12. Resistência à fratura de coroas metalocerâmicas implanto-suportadas cimentadas e parafusadas / Fracture resistance of metal-ceramic cement- and screw-retained implant-suport single crowns
Nas próteses sobre implante, a escolha do sistema de retenção (cimentada ou parafusada) muitas vezes está relacionada com a preferência pessoal de cada profissional. Porém alguns aspectos que diferem esses tipos de prótese devem ser levados em consideração no momento desta seleção. A passividade de assentamento, a reversibilidade, a estética, a o
