Failure analysis of a Ti6Al4V cementless HIP prosthesis

open access: yesEngineering Failure Analysis, 2007
This work investigates the causes of in vivo fracture of a cementless hip prosthesis model manufactured with Ti6A14V alloy. To this end an assessment of geometric characteristics, a fractographic analysis of the fracture surface, and a microstructural study of the stem material were carried out.

Dual-Modular Stems for Primary Total Hip Arthroplasty

open access: yesEncyclopedia, 2022
In primary total hip arthroplasty (THA), dual-modular stems were introduced to better restore hip stability, femoral offset, and leg length. This entry highlights the gathered knowledge about dual-modular stems and related complications in combinations ...

Strategies to reduce torque loss of abutment screws

open access: yesJournal of Oral Research and Review, 2018
Aim: The loosening of abutment screws is a recurrent problem in oral implantology that lacks a consensual solution. The aim of this paper is to review the literature available in search for strategies that might lessen the torque loss of abutment screws.

Catastrophic failure of a monolithic zirconia prosthesis

open access: yesThe Journal of Prosthetic Dentistry, 2015
Recently, monolithic zirconia restorations have received attention as an alternative to zirconia veneered with feldspathic porcelain to eliminate chipping failures of veneer ceramics. In this clinical report, a patient with mandibular edentulism received 4 dental implants in the interforaminal area, and a screw-retained monolithic zirconia prosthesis ...

Early stenotic prosthesis failure after implantation of a stentless porcine aortic valve prosthesis [PDF]

open access: yesInteractive CardioVascular and Thoracic Surgery, 2011
Stentless biological aortic prostheses are used routinely in aortic valve replacement surgery, offering beneficial hemodynamics compared to stented biological valves of similar size. We report here a rare case of early stenotic prosthesis failure of a RootElan stentless porcine aortic valve prosthesis due to swelling at the bottom of the right coronary

On the Analysis of the Contact Conditions in Temporomandibular Joint Prostheses [PDF]

open access: yes, 2018
Temporomandibular joint replacement (TMJR) is a complex surgical procedure in which the artificial joints available must assure the anatomical reconstruction and guarantee a good range of the natural temporomandibular joint (TMJ) movements. With this aim,

Autoinflation Leading to Failure of Two-Piece Ambicor Implantable Penile Prosthesis: An Outcome from a Methodical Treatment of Recalcitrant Stuttering Priapism

open access: yesCase Reports in Urology, 2014
Introduction. We present the case of a patient who received a two-piece Ambicor penile prosthesis for idiopathic recurrent “stuttering” priapism refractory to other treatment options.

Finite element analysis of porously punched prosthetic short stem virtually designed for simulative uncemented hip arthroplasty [PDF]

open access: yes, 2017
Background: There is no universal hip implant suitably fills all femoral types, whether prostheses of porous short-stem suitable for Hip Arthroplasty is to be measured scientifically.
