Towards High‐Acuity Vision Restoration: Hybrid Retinal Prosthesis Composed of a High‐Density Multielectrode Array Integrated With Glutamatergic Cells

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a novel Hybrid Retinal Implant (HRI), composed of a high‐density electrode array integrated with glutamatergic neurons to overcome key limitations of current retinal prostheses. The significant reduction of activation threshold and of electrode cross‐talk yields in an improved spatial resolution.

Dental implant-retained auricular prosthesis

open access: yesDental Research Journal, 2018
Absence or loss of facial structures causes functional deficits and enormous psychological distress, so rehabilitation is necessary. However, facial prostheses have some difficulties due to mobile underlying tissues and retention. We used dental implant instead of conventional maxillofacial implant and safe on four prosthetic systems which is used in ...
