The Relationship Between Implant Preload and Screw Loosening on Implant-supported Prostheses [PDF]
Journal of Oral Implantology, 2002 The purpose of this study was to determine whether varying the preload on the implant-abutment complex would affect screw loosening under simulated loading conditions. Abutment screws in sample models were tightened to 25, 30, 35, and 40 N-cm. One group of samples was allowed to stand for 3 hours after being torqued and then loosened.

Implantable metaverse with retinal prostheses and bionic vision processing
Optics Express, 2023 We present an implantable metaverse featuring retinal prostheses in association with bionic vision processing. Unlike conventional retinal prostheses, whose electrodes are spaced equidistantly, our solution is to rearrange the electrodes to match the distribution of ganglion cells.

Nickel sensitivity and the implantation of orthopaedic prostheses [PDF]
Contact Dermatitis, 1993 There is no evidence that nickel‐sensitive patients, when given a modern plastic‐to‐steel hip replacement, develop cutaneous reactions or loosening of their prostheses. However, eczema I occasionally seen with static metal prostheses and eruptions sometimes accompanied the use of the older types of joint prosthesis.

Biomaterials for orbital implants and ocular prostheses: Overview and future prospects
Acta Biomaterialia, 2014 The removal of an eye is one of the most difficult and dramatic decisions that a surgeon must consider in case of severe trauma or life-threatening diseases to the patient. The philosophy behind the design of orbital implants has evolved significantly over the last 60 years, and the use of ever more appropriate biomaterials has successfully reduced the

Cochlear implants and other inner ear prostheses: today and tomorrow
Current Opinion in Physiology, 2020 Cochlear implants (CIs) are implantable auditory prostheses designed to restore access to sound in deaf individuals via direct electrical stimulation of the auditory nerve. While CIs have been successful in restoring speech perception to many deaf patients, outcomes are variable and speech recognition in noise remains a problem.
