Retrospective cohort study of rough-surface titanium implants with at least 25 years’ function

International Journal of Implant Dentistry, 2017
Background The longitudinal clinical outcomes over decades contribute to know potential factors leading to implant failure or complications and help in the decision of treatment alternatives. Methods The cases of all patients who received dental implants

Cochlear implants [PDF]

Current Biology, 2014
Cochlear implants are the first example of a neural prosthesis that can substitute a sensory organ: they bypass the malfunctioning auditory periphery of profoundly-deaf people to electrically stimulate their auditory nerve. The history of cochlear implants dates back to 1957, when Djourno and Eyriès managed, for the first time, to elicit sound ...

Countertorque testing and histomorphometric analysis of various implant surfaces in canines: a pilot study. [PDF]

, 1997
As surface roughness may play a role in the mechanical attachment of an implant surface to bone, various implant surfaces have been prepared and analyzed by removal torque (countertorque) or push-out tests in a variety of animal model systems.

Consistent and chronic cochlear implant use partially reverses cortical effects of single sided deafness in children

Scientific Reports, 2020
Potentially neuroprotective effects of CI use were studied in 22 children with single sided deafness (SSD). Auditory-evoked EEG confirmed strengthened representation of the intact ear in the ipsilateral auditory cortex at initial CI activation in ...

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 application of niobium and tantalum oxides for implant surface passivation. [PDF]

, 2007
Despite the advantages of ceramics, with their high corrosion stability in vivo, most medical implant constructions are still made from metals [1]. To increase the corrosion stability of metals, different coatings are applied to the implant surfaces,

Evaluation of maxillary sinus floor augmentation with the crestal approach and beta-tricalcium phosphate: a cone-beam computed tomography 3- to 9-year follow-up

International Journal of Implant Dentistry, 2020
Background We performed maxillary sinus floor augmentation using the crestal approach and beta-tricalcium phosphate (β-TCP) and a long-term evaluation using cone-beam computed tomography (CBCT). Methods Twenty-three patients (30 implants) underwent sinus

Probabilistic finite element analysis of the uncemented hip replacement-effect of femur characteristics and implant design geometry [PDF]

, 2010
In the present study, a probabilistic finite element tool was assessed using an uncemented total hip replacement model. Fully bonded and frictional interfaces were investigated for combinations of three proximal femurs and two implant designs, the ...

Vertical ridge augmentation using a porous composite of uncalcined hydroxyapatite and poly-DL-lactide enriched with types 1 and 3 collagen

International Journal of Implant Dentistry, 2019
Background Previous studies have shown that porous composite blocks containing uncalcined hydroxyapatite (u-HA; 70 wt%) with a scaffold of poly-DL-lactide (PDLLA, 30 wt%) are biodegradable, encourage appropriate bone formation, and are suitable for use ...
