cochlear implant

A cochlear implant is an electronic medical device for people with severe-to-profound hearing loss. It works by transforming sounds into electrical signals that are sent straight to the auditory nerve. This means that it can bypass damaged areas of the ear.

Cohort study

A longitudinal study in which a group, the cohort, is chosen for the presence of a specific characteristic at or during a specified time and followed over time to discover presumably related characteristics.

Compter-aided navigation

Surgical placement of implants using a computer guided system based on information generated from a high resolution computed tomography.

conical connection

dental: A conical connection is an abutment connection with dental implants. Conical connections are said to be linked with the implant so tight, that they have no micromovement and help avoiding bacteria to enter into the inner part of the dental implant.   literature: https://implant-register.com/multicenter-study-evaluating-the-novel-tapered-conical-connection-implants-1-year-results/
