Avaliação biomecânica de próteses parciais fixas sobre implantes com diferentes...
Reis, Francisco Carlos dos Santos; Santos, Felipe Antunes dos; Lima, Ricardo Seixas de Paiva; Boaro, Letícia Cidreira; Miranda, Milton EdsonEste estudo avaliou o comportamento de implantes com diferentes geometrias cervicais em prótese de três elementos em região posterior de mandíbula pelo método de elementos finitos. Para isso, quatro modelos foram criados no software SolidWorks Professional 2013®, no formato de um bloco ósseo, simulando a reabilitação de três elementos em cerâmica à base de zircônia, suportada por dois implantes nas regiões dos ...
Stress distribution in prosthetic abutments: a finite element analysis comparis...
Araújo, Cristiano Garcia; Miranda, Milton Edson; Dini, Caroline; Silva, Gabrielle Alencar Ferreira; Olivieri, Karina Andrea NovaesThe effect of prosthetic abutment type on single-screwed prostheses in posterior mandibular molar rehabilitations is not yet known. Thus, the aim of this study was to evaluate the distribution of stresses in the crowns, prosthetic components, implant and bone in implant-supported restorations with or without a prosthetic abutment, maintaining an equal total height of the implant-crown set. Virtual 3-dimensional...
Stress analysis of a single prosthesis on a poorly positioned implant
Reis, Francisco Carlos dos Santos; Brandt, William Cunha; Boaro, Letícia Cristina Cidreira; Miranda, Milton EdsonThe mechanical positioning behavior of a mal-positioned implant was evaluated in the finite element method. Models were created in SolidWorks Professional 2013® software with a single implant rehabilitation. The following were analyzed: Control Group, crown aligned to the implant long axis; Experimental Group, crown shifted 3 mm mesial proximally to the implant axis. Compressive stresses in cortical and medulla...
Stresses in lithium disilicate crowns and zirconia implants in patients with br...
Patricio, Marina Denardi; Caldas, Ricardo Armini; Miranda, Milton Edson; Olivieri, Karina Andrea Novaes; Brandt, Willian Cunha; Vitti, Rafael PinoThe aim of this study was to analyze by finite element analysis the influence of the use occlusal splints in rehabilitation with zirconia implant under oblique and vertical masticatory loads. Four models were developed to simulate a clinical of absence of a premolar (element 45) replaced by zirconia implant and lithium disilicate crown. Four groups were created, SP-V without occlusal splint and vertical load; C...

Andrade de Freitas, Sandra Lucia; Brandt, William Cunha; Miranda, Milton Edson; Vitti, Rafael PinoMade available in DSpace on 2019-09-12T16:56:48Z (GMT). No. of bitstreams: 0 Previous issue date: 2018; Objective. To evaluate the shear bond strength between different artificial teeth and denture base polymerized by two polymerization methods submitted to thermocycling. Materials and Methods. Two acrylic resins were selected according to the polymerization method (water-bath and microwave), and four different...
Evaluation of the accuracy of different transfer impression techniques for mult...
Faria, Júlio César Brigolini de; Silva-Concílio, Laís Regiane da; Neves, Ana Christina Claro; Miranda, Milton Edson; Teixeira, Marcelo LucchesiMade available in DSpace on 2019-09-12T16:26:01Z (GMT). No. of bitstreams: 0 Previous issue date: 2011; The aim of this study was to evaluate the accuracy of three implant transfer impression techniques. Four groups (n = 5) were defined, according to the technique: TC - tapered copings without splint; SC - square copings without splint; SCS - square copings splinted with dental floss and acrylic resin, and CG (...
Dimensional accuracy of different impression techniques of partially eden - tul...
Vitti, Rafael Pino; Feitosa, Victor Pinheiro; Bacchi, Ataís; Brandt, William Cunha; Miranda, Milton Edson; Sinhoreti, Mário Alexandre CoelhoObjective The purpose of this in vitro study was to assess and compare the dimensional accuracy of three impression techniques: 1-step putty/light-body, 2-step putty/light-body, and the monophase technique. Methods A partially edentulous standard stainless steel mandibular arch cast with reference points on the teeth was used to make the impressions. The anteroposterior and transverse distances were measured. A...
