Article Synopsis
- - The study investigates the effect of a 1% metformin solution on bone growth in an animal model using guided bone regeneration (GBR) techniques with a bovine hydroxyapatite xenograft.
- - Eight male New Zealand rabbits had created bone defects filled with either metformin solution or saline, and after six weeks, the samples were analyzed for new bone formation and material integration.
- - Results showed that metformin led to greater bone formation and better integration of the graft compared to the control group, although the differences in average measurements were not statistically significant.
Consequences of Peri-Implant Bone Loss in the Occlusal Load Transfer to the Supporting Bone in terms of Magnitude of Stress, Strain, and Stress Distribution: A Finite Element Analysis.
Biomed Res Int
September 2021
Methods: Three models of a single internal connection bone level-type implant inserted into a posterior mandible bone section were constructed using a 3D finite element software: one control model without marginal bone loss and two test models, both with a circumferential peri-implant bone defect, one with a 3 mm high defect and the other one 6 mm high. A 150 N static load was tested on the central fossa at 6° relative to the axial axis of the implant.
Results: The results showed differences in the magnitude of strain and stress transferred to the bone between models, being the higher strain found in the trabecular bone around the implant with greater marginal bone loss.
Background: Implantoplasty reduces both implant diameter and the thickness of its walls, subsequently reducing the ability of the implant to resist fracture in response to functional load. In combination with an increase in the crown-implant ratio due to bone loss, this could increase the lever effect, which in presence of high masticatory forces or parafunctional habits, could lead to complications such as fracture of the implant or loosening of the prosthetic screw.
Objectives: To determine the elastic limits of internal connection, dental implants of different designs and diameters after an implantoplasty.
Influence of cortical bone and implant design in the primary stability of dental implants measured by two different devices of resonance frequency analysis: An study.
J Clin Exp Dent
March 2020
Background: This study aimed to evaluate the effect of the implant design and the presence of cortical bone in the primary stability, as well as analyze the differences between the stability measurements obtained by two different resonance frequency analysis (RFA) devices.
Material And Methods: A total of 80 Klockner implants of two different models [40 Essential Cone implants (group A) and 40 Vega implants (group B)] were used. The implants were placed in two polyurethane blocks that simulated the mechanical properties of the maxillary bone.
Background/purpose: The use of osteotomes as a technique for densification and expansion of the residual ridge is one of the most widely used procedures to achieve adequate peri-implant bone quantity and density. The aim of this study was to evaluate the influence of time and the elastic deformation of peri-implant bone in the primary stability of implants placed using osteotomes.
Materials And Methods: In each of 10 fresh fragments of cow rib, two implants were placed using osteotomes.
