The image shows an Ivory Matrix Retainer, also known as an Ivory Separator, constructed from stainless steel.
This dental instrument is designed to hold and tighten a matrix band around a tooth during restorative procedures, such as Class II cavity restorations.
Its unique oval-shaped frame provides stability, while the central screw mechanism allows controlled adjustment of the band tension.
The retainer helps ensure proper contour and contact points when placing composite or amalgam restorations.
Durable and autoclavable, it is widely used for precise tooth isolation and shaping.
FAQs:
1. What is the purpose of the separator design?
The separator-style frame stabilizes the band and provides sufficient tension to contour the filling material correctly.
2. Is this instrument reusable?
Yes, Ivory Matrix Retainers are made of stainless steel and can be sterilized for repeated use.
3. Which procedures require this instrument?
It is primarily used in Class II cavity restorations where adjacent tooth walls need proper shaping during filling material placement.
4. How does the screw mechanism work?
The screw tightens or loosens the matrix band, allowing the clinician to adjust the pressure for ideal placement and contouring.
5. Is it compatible with all matrix bands?
It is designed to fit most standard metal matrix bands commonly used in dental restorative procedures.
