Evaluation of Torque Maintenance of Abutment and Cylinder Screws With Morse Taper Implants
(Lippincott Williams & Wilkins, 2012-11-01)
The screw loosening of implant-supported prostheses is a common mechanical failure and is related to several factors as insertion torque and preload. The aim of this study was to evaluate the torque maintenance of retention ...
Photoelastic Analysis of Cemented or Screwed Implant-Supported Prostheses With Different Prostheses Connections
(Allen Press Inc, 2011-08-01)
The aim of this study was to evaluate the stress distribution of different retention systems (screwed or cemented) associated with different prosthetic connections (external hexagon, internal hexagon, and Morse taper) in ...
Three-dimensional finite element analysis of stress distribution in retention screws of different crown-implant ratios
(2013-08-21)
The retaining screw of the implant-supported dental prosthesis is the weakest point of the crown/implant system. Furthermore, crown height is another important factor that may increase the lever arm. Therefore, the aim of ...
Postsurgical Care for Rehabilitation With Implant-Retained Extraoral Prostheses
(Lippincott Williams & Wilkins, 2010-03-01)
The health of a peri-implant tissue is a critical factor for the long-term success of treatment with extraoral implants. However, infection and inflammation may occur and lead to implant loss and prostheses failure. ...
Biologic width changes around loaded implants inserted in different levels in relation to crestal bone: histometric evaluation in canine mandible
(Blackwell Publishing, 2008-05-01)
Objectives: The aim of the present study was to evaluate histometric changes around dental implants inserted at different levels in relation to the crestal bone, under different loading conditions.Material and methods: ...
Influence of implant positioning in extraction sockets on osseointegration: Histomorphometric analyses in dogs
(2010-01-01)
Aim: To evaluate the influence of implant positioning into extraction sockets on osseointegration. Material and methods: Implants were installed immediately into extraction sockets in the mandibles of six Labrador dogs. ...
Osseointegration assessment of chairside argon-based nonthermal plasma-treated Ca-P coated dental implants
(2013-01-01)
This study investigated the effect of an Argon-based nonthermal plasma (NTP) surface treatment-operated chairside at atmospheric pressure conditions applied immediately prior to dental implant placement in a canine model. ...
Implantes de polietileno gel e poroso em cavidade anoftálmica de coelhos
(Conselho Brasileiro de Oftalmologia, 2006-06-01)
OBJETIVO: Comparar implantes de polietileno poroso no estado sólido e gel em cavidades enucleadas. MÉTODOS: Trinta e seis coelhos albinos foram submetidos à enucleação do olho direito, recebendo esferas de polietileno ...
Influence of presence or absence of teeth adjacent to implants installed immediately into extraction sockets on peri-implant hard tissue levels: An experimental study in the dog
(2013-03-01)
Aim: To evaluate the influence of the presence or absence of adjacent teeth on the level of the mesial and distal alveolar bony crest following healing at sites where implants were installed immediately into extraction ...
