1. Influence of Abutment Collar Height and Implant Length on Stress Distribution in Single Crowns
Resumo Este estudo avaliou a influência da altura da porção transmucosa do pilar protético com junção cone morse e do comprimento dos implantes no comportamento biomecânico coroas unitárias com diferentes proporção coroa-implante. Seis modelos virtuais (S11, M11, L11, S13, M13 e L13) foram construídos combinando pilares protéticos com transmucoso

2. 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

3. Effects of different torque levels on the implant-abutment interface in a conical internal connection
Abstract The fit of the implant-abutment interface was assessed by the metallographic technique and by scanning electron microscopy (SEM), using solid abutment types at different torque levels. Forty Morse taper connections and forty solid abutments were used at different torque levels (repeated after 10 minutes) in the following groups (n = 10): 25 Ncm (gro

4. Morse taper internal connection implants: would abutment reseating influence retention?
Abstract Aim: To investigate whether the removal and reseating of the abutment influences the retention of Morse taper implant system. Methods: Two Morse taper implant systems were selected: Bicon Dental ImplantTM system (Bicon, LLC, Boston, MA, USA) and Kopp Implant(r) system (Kopp(r), Curitiba, PR, Brazil). In both systems, the abutment is connected to

5. Strain analysis of different diameter Morse taper implants under overloading compressive conditions
The aim of this study was to evaluate the amount of deformation from compression caused by different diameters of Morse taper implants and the residual deformation after load removal. Thirty Morse taper implants lacking external threads were divided into 3 groups (n = 10) according to their diameter as follows: 3.5 mm, 4.0 mm and 5.0 mm. Two-piece abutments

6. Bacterial microleakage at the implant-abutment interface in Morse taper implants
AIM: To evaluate the microleakage at the implant-abutment (I-A) interface of Morse tapered implants inoculated with different volumes of bacterial suspension. METHODS: Morse tapered I-A sets were selected and divided in two groups depending on the type of abutment: passing screw (PS) and solid (S), and then subdivided into four subgroups (n=6) accordin

7. In Vitro Microbiological Analysis of Bacterial Seal at the Implant-Abutment Interface Using Two Morse Taper Implant Models
O objetivo deste estudo foi avaliar comparativamente, por meio de análise microbiológica in vitro, a capacidade de selamento bacteriano de dois modelos de implante de encaixe morse. Foram utilizados 15 implantes com travamento de seus respectivos mini-pilares por fricção, sem auxílio de parafuso (Grupo 1) e 30 implantes com travamento de seus respectivo

8. Effect of aluminum oxide blasting and use of industrial sealant on the outer abutment surface of the prosthetic morse taper system connection on the untightening torque / Efeito do jateamento de óxido de alumínio e uso de selante industrial, na superfície de pilares protéticos Cone Morse, de restaurações implanto suportadas sobre a resistência ao contratorque
Problemas com desenho de conexões protéticas sobre implantes, microfendas, afrouxamento e, consequentemente, perdas das estruturas protéticas reabilitadoras são tópicos frequentes do estudo odontológico. Conexões do tipo Cone Morse, devido às suas características, diminuíram o índice desses problemas, abrindo uma nova perspectiva para o sucesso da

9. Estudo in vitro de um material para selamento da interface implante-intermediário do tipo minipilar cônico em implantes de hexágono externo, hexágono interno e cone morse / In vitro sealing of a material of implant-abutment interface of mini conical pillar: inimplant external hexagon, internal hexagon and Morse taper
Microbial and fluidic leakage in the implant-abutment interface are shown in literature through a variety of studies, accusing the space that exists between the components of the implant, called \"GAP\", which seems to be the source of the microorganism infiltration, either from the external to the internal environment or the inverse, resulting in inflammato

10. Análise tridimensional por elemento finito do comportamento biomecânico de próteses totais fixas implantossuportadas : efeito do tipo de conexão protética, cargas oclusais e número de implantes / Three-dimensional finite element analysis of biomechanics of implant-supported fixed prostheses : effect of connection system, occlusal load, and number of implants
The purpose of this study was to analyze the stress and strain distribution by three-dimensional finite element method in implant supported fixed prostheses and peri-implantar bone region, using two types of implant-abutment connection internal and external, correlated to the effect of axial loadings and number of implants. Virtual models were developed by s

11. Measurement of the morse taper abutment removal torque in dental implants using a carbon deposition above the attrition surface / Mensuração do torque de desaperto do componente protético em conexão do tipo cone-morse em implantes dentários utilizando deposição de carbono sobre a superfície de atrito
Os implantes cone morse apresentam um travamento e vedamento por meio de atrito entre as paredes do implante e do pilar protético. Nos sistemas convencionais do tipo Hexágono externo e interno, para reduzir o afrouxamento dos parafusos protéticos, são utilizados materiais de cobertura de superfície, como carbono e ouro. Não foram encontradas referênci

12. Avaliação mecânica da estabilidade de parafusos protéticos em diferentes sistemas de retenção pilar/implante / Mechanical evaluation of the prosthetic screw stability from different implant/abutment retention systems
The preload screw variation for the first five minutes after each one of five torque/untorque sequences from different implant/abutment retention systems was evaluated. Strain gauges were attached over the cervical third of external hex, internal hex and Morse taper implants. A controlled torque/untorque procedure allowed the record from the preload and unto
