Mechanical evaluation of four narrow-diameter implant systems

Made available in DSpace on 2022-04-28T19:00:18Z (GMT). No. of bitstreams: 0 Previous issue date: 2014-01-01; Purpose: This study aimed to evaluate the survival probability of four narrow-diameter implant systems when subjected to fatigue loading. Materials and Methods: Seventytwo narrow-diameter implants to be restored with single-unit crowns were divided into four groups (n = 18): Astra Tech (3.5-mm diameter)...

Implant prosthodontics: In vitro testing methods

Made available in DSpace on 2022-04-29T07:14:13Z (GMT). No. of bitstreams: 0 Previous issue date: 2012-10-01; While randomized controlled clinical studies are strongly suggested as the optimal approach to evaluate the performance of biomaterials and design aspects of dental implants and prosthetic components, these studies are at times not economically viable. Thus, well designed in vitro studies associating vi...

Made available in DSpace on 2022-04-29T07:20:15Z (GMT). No. of bitstreams: 0 Previous issue date: 2014-01-01; Purpose: To evaluate and compare the reliability of implant-supported single crownsabutments retained with coated (C) or noncoated (NC) screws and onto platform-switched abutments with coated screws. Materials and Methods: Fifty-four implants (DT Implant 4-mm Standard Platform, Intra-Lock International)...

Early bone healing and biomechanical fixation of dual acid-etched and as-machin...

Made available in DSpace on 2022-04-28T22:37:15Z (GMT). No. of bitstreams: 0 Previous issue date: 2011-01-01; To evaluate the biomechanical fixation, bone-to-implant contact (BIC), and bone morphology of screw-type root-form implants with healing chambers with as-machined or dual acid-etched (DAE) surfaces in a canine model. Materials and Methods: The animal model included the placement of machined (n = 24) and...

Influence of estrogen deficiency on bone around osseointegrated dental implants...

Made available in DSpace on 2022-04-28T22:48:46Z (GMT). No. of bitstreams: 0 Previous issue date: 2011-07-01; Purpose: The aim of this study was to evaluate the influence of estrogen deficiency on bone around osseointegrated dental implants in a rat jaw model. Materials and Methods: This study used 16 female rats that had the first molars bilaterally extracted and were allowed to heal for 30 days before implant...

Influence of implant design on the biomechanical environment of immediately pla...

Made available in DSpace on 2022-04-29T03:22:07Z (GMT). No. of bitstreams: 0 Previous issue date: 2011-01-01; Purpose: To evaluate the influence of different implant designs on the biomechanical environment of immediately placed implants. Materials and Methods: Computed tomography (CT) -based finite element models comprising a maxillary central incisor socket and four commercially available internal-connection ...
