13. Misfit and fracture load of implant-supported monolithic crowns in zirconia-reinforced lithium silicate
Abstract Zirconia-reinforced lithium silicate (ZLS) is a ceramic that promises to have better mechanical properties than other materials with the same indications as well as improved adaptation and fracture strength. Objective In this study, marginal and internal misfit and fracture load with and without thermal-mechanical aging (TMA) of monolithic ZLS and

14. Pilares cerâmicos na implantodontia: revisão de literatura
Resumo Os pilares protéticos, usados como intermediários entre a prótese e o implante, são feitos de titânio e outros metais, que possuem estrutura confiável. A cor acinzentada desses metais, acrescidos a recessão gengival e a camadas finas de tecidos adjacentes, acaba exposta, o que compromete a estética. Com isso, foram introduzidos os pilares cer�

15. Prosthetic abutment influences bone biomechanical behavior of immediately loaded implants
Abstract This study aimed to evaluate the influence of the type of prosthetic abutment associated to different implant connection on bone biomechanical behavior of immediately and delayed loaded implants. Computed tomography-based finite element models comprising a mandible with a single molar implant were created with different types of prosthetic abutment

16. 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

17. Influence of implant-abutment angulations and crown material on stress distribution on central incisor: a 3D FEA
Abstract Aim: To investigate the effect of implant-abutment angulation and crown material on stress distribution of central incisors. Finite element method was used to simulate the clinical situation of a maxillary right central incisor restored by two different implant-abutment angulations, 15° and 25°, using two different crown materials (IPS E-Max CAD

18. Active Bone Conduction Prosthesis: BonebridgeTM
Introduction Bone conduction implants are indicated for patients with conductive and mixed hearing loss, as well as for patients with single-sided deafness (SSD). The transcutaneous technology avoids several complications of the percutaneous bone conduction implants including skin reaction, skin growth over the abutment, and wound infection. The Bonebridge

19. An Indirect Method to Measure Abutment Screw Preload: A Pilot Study Based on Micro-CT Scanning
Resumo Este estudo teve como objetivo medir a pré-carga em diferentes conexões implante/pilar baseado em imagens de micro-CT. Implantes de hexágono externo (EH) e Cone Morse (MT) (n = 5) foram utilizados para a medição de pré-carga. Os parafusos de pilares foram digitalizados em um micro-CT de alta resolução para obter seus modelos virtuais, que fora

20. 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

21. Failure of prosthetic screws on 971 implants
Abstract Aim: To evaluate the presence of failures in prosthetic screws and whether these failures are related to the type of prosthesis, abutment angulation and presence or not of intermediate. Methods: Two-hundred and sixty-seven patients were evaluated at the Federal University of Santa Catarina, totaling 971 external hexagonal implants in place for at

22. Effect of Mechanical Cycling on Screw Torque in External Hexagon Implants with and without Platform Switching
Este estudo in vitro avaliou o efeito da ciclagem mecânica no torque dos parafusos de retenção em implantes de hexágono externo com plataforma switching (PS), plataforma regular (RP) e plataforma larga (WP). Foram utilizados 30 corpos de prova divididos em 3 grupos equitativamente: PS, RP e WP. Cada corpo de prova foi preparado com implantes: 3,75x10 mm

23. Effect of Using Nano and Micro Airborne Abrasive Particles on Bond Strength of Implant Abutment to Prosthesis
A conexão das próteses nos pilares dos implantes dentários é um fator de preocupação e a obtenção de uma retenção satisfatória tem sido objeto de estudos recentes em próteses com retenção cementária. O jateamento é um método de obter uma superfície áspera para aumentar a retenção. O objetivo d

24. 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
