COMPARISON OF CEMENT AND SCREW FIXATION OF ORTHOPEDIC STRUCTURES

Сучасні медичні технології, 2022
In dental prosthetics, every detail is important, because at this stage, not the aesthetic component is put in the first place, but the issue of engraftment of the implant.

Implant–abutment connections: influence of the design on the microgap and their fatigue and fracture behavior of dental implants

Journal of Materials Science: Materials in Medicine, 2014
Microgap between implant and abutment can produce biological and mechanical problems such as peri-implantitis and/or fatigue failures. The aim of this study was to evaluate microgap size and fatigue behavior of external and internal connections. In both systems the torque to tighten the abutment screw of single crown abutments was 45 Ncm.

Short dental implants in the posterior region : the effect of platform-switching and a nanorough surface on peri-implant bone loss [PDF]

, 2012
Korte implantaten (10 mm lengte), waarvoor meerdere redenen bestaan. In de eerste plaats heeft een kort implantaat minder oppervlak beschikbaar voor contact tussen bot en implantaat dan een langer implantaat met eenzelfde diameter.

The Influence of Design on Stress Concentration Reduction in Dental Implant Systems Using the Finite Element Method

Crystals, 2023
Dental implant fracture is closely connected to the stress buildup surrounding the implant system during static loading. In areas where the cross-section of the implant rapidly changes or where the geometry of the implant system has discontinuities ...

Fracture and Fatigue of Dental Implants Fixtures and Abutments with a Novel Internal Connection Design: An In Vitro Pilot Study Comparing Three Different Dental Implant Systems

Journal of Functional Biomaterials, 2022
The aim of this study was to compare the mechanical behaviors of three dental implant fixtures with different abutment connection designs. Three implant systems were studied: the control (BLX implant), test group 1 (TORX++ implant), and test group 2 (IU ...

The effect of dynamic loading on bacterial microleakage of the dental implant fixture-abutment interface: An in vitro study

The Journal of Indian Prosthodontic Society, 2021
Aim: Bacterial micro leakage at implant-abutment interface under functional loading is an important factor, may lead to crestal bone loss and affect the long term success of dental implants.

INFLUENCE OF DIFFERENT IMPLANT ABUTMENT CONNECTION DESIGNS ON ABUTMENT SCREW LOOSENING IN DENTAL IMPLANT SYSTEMS – A SYSTEMATIC REVIEW.

International Journal of Medical and Biomedical Studies, 2019
Background: Dental implants have provided an alternative method of prosthetic rehabilitation with high long-term success rates. However, mechanical or biological complications may occur with implants amongst which loosening of the screw is very common. Loosening of the screw might cause misfit of implant?abutment interface and may occur due to preload ...

Osseointegration of zirconia implants compared with titanium : an in vivo study [PDF]

, 2008
Background Titanium and titanium alloys are widely used for fabrication of dental implants. Since the material composition and the surface topography of a biomaterial play a fundamental role in osseointegration, various chemical and physical surface ...
