POST TREATMENT DEVICE FOR HA COATING LAYER OF DENTAL IMPLANT SURFACE

摘要

PURPOSE: A hydroxyapatite (HA) coating layer-post processing apparatus is provided to improve osseointegration of implant by increasing crystallization of HA coating layer over 97 %, and to prevent oxidative stain of a roughening layer. CONSTITUTION: A hydroxyapatite (HA) coating layer-post processing apparatus comprises: a first space performing a heat treatment to enhance crystallization of the HA coating layer under ambient environment; a heat treatment chamber comprising a second space to prevent oxidative stain of a roughening layer under an inert gas atmosphere; and a heat barrier wall separating the first and second spaces, and formed with a through-hole in which the implant is penetrated and fixed.
