Stress distribution in the peri-implant area of pure titanium and titanium-zirconium small implants

Brazilian Journal of Oral Sciences, 2019
Aim: In dental implant treatment, there is a demand for mechanically stronger implants. Despite the existence of several studies showing the clinical success of narrow diameter implants, most of them are based on pure titanium (cpTi) alloys.

Biomechanical evaluation of one-piece and two-piece small-diameter dental implants: In-vitro experimental and three-dimensional finite element analyses

Journal of the Formosan Medical Association, 2016
Small-diameter dental implants are associated with a higher risk of implant failure. This study used both three-dimensional finite-element (FE) simulations and in-vitro experimental tests to analyze the stresses and strains in both the implant and the ...

Unravelling the functional biomechanics of dental features and tooth wear [PDF]

, 2013
Most of the morphological features recognized in hominin teeth, particularly the topography of the occlusal surface, are generally interpreted as an evolutionary functional adaptation for mechanical food processing.

Stress analysis and factor of safety in three dental implant systems by finite element analysis

The Saudi Dental Journal, 2022
The purpose of this study was to compare the stress distribution and the factor of safety of three dental implant systems using the finite element method.Three commercial dental implant systems were designed using Solid Works 2020 software: Model A with an internal octagonal connection and matching platform, Model B with an internal hexagon connection ...

An analysis of stress and burnout in UK general dental practitioners: subdimensions and causes [PDF]

British Dental Journal, 2019
Dentistry is well documented as a stressful profession. The majority of UK dentists work in general practice, which can carry multiple sources of stress. Previous research has acknowledged the propensity of these sources of stress for general dental practitioners (GDPs) when undertaking clinical, administrative and managerial tasks.

Construction of unbiased dental template and parametric dental model for precision digital dentistry [PDF]

arXiv, 2023
Dental template and parametric dental models are important tools for various applications in digital dentistry. However, constructing an unbiased dental template and accurate parametric dental models remains a challenging task due to the complex anatomical and morphological dental structures and also low volume ratio of the teeth.
