The Practical Applications of New Isolation System “Multi-Purpose Vacuum Instrument ZOO” to the Prosthodontics

Abstract

There are several intra-oral factors that possibly affect the bonding strength of the adhesives. These include saliva, blood, exudates from sulcus, humidity of expiration, and body temperature. Besides those, lip, cheek and tongue may disturb the adhesive procedure and result in bonding failure. In order to obtain reasonable bonding, it is necessary to control or eliminate the abovementioned factors.
Multi-purpose vacuum instrument, namely ZOO, was developed for adhesion without contamination. This serves as the equipment for suction, isolation, retraction, dehumidification, and mouth opener, as well.
In this report, the practical applications of the ZOO for the prosthetic procedures are explained.
