1. Morse taper performance: A finite element analysis study
OBJECTIVES: To evaluate and compare the magnitude and distribution of stresses generated on implants, abutments and first molar metal-ceramic crowns using finite element analysis. METHODS: Preliminary three-dimensional models were created using the computer-aided design software SolidWorks. Stress and strain values were observed for two distinct virtual mo

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. 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

4. 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

5. 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

6. 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

7. 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

8. Fracture resistance of metal-ceramic and all-ceramic crowns made with and without reinforced coping design / Avaliação da resistência à fratura em coroas metalocerâmicas e ceramocerâmicas, utilizando infra-estruturas com e sem reforço
As restaurações metalocerâmicas apresentam relatos de sucesso clínico a longo prazo e as características de reforço (cinta lingual e poste proximal) das infra-estruturas metálicas parecem ser de grande importância para este sucesso. Estes reforços freqüentemente estão ausentes nas infraestruturas das restaurações ceramocerâmicas. O objetivo des

9. Pilot study of the adhesion between Ni-Cr alloys and ceramics when prosthetic variables were accomplish / Efeito das variáveis laboratoriais protéticas na adesão da porcelana com ligas de níquel-cromo
The metalceramic crowns are usually used in dentistry because they provide a resistant structure due to its metallic base and its aesthetics from the porcelain that recovers this structure. To manufacture these crowns, a series of stages should be accomplished in the prosthetic laboratories, and many variables can influence its success. Changes in these vari

10. Comparative study of the resistance to compression forces of a fractured metal ceramic crown and repaired with composite resin with a non-fractured metal ceramic crowns and a permanent natural tooth / "Estudo comparativo da resistência às forças de compressão de uma coroa metalocerâmica fraturada e reparada com resina composta híbrida fotopolimerizável com um dente natural permanente e com uma coroa metalocerâmica íntegra"
As porcelanas odontológicas têm sido dos materiais restauradores estéticos aqueles que mais têm evoluído nos últimos anos. Tradicionalmente, elas são friáveis e incapazes de suportar deformações estruturais quando submetidas a stress. Quando usadas na construção de próteses parciais fixas, uma subestrutura metálica é necessária para impedir q
