Tofflemire-Universal 90 Bend 15.cm

The Tofflemire Universal 90 Bend 15 cm is a specialized dental matrix retainer used in restorative dentistry to hold and stabilize matrix bands during cavity restoration procedures. It is an advanced variation of the standard Tofflemire retainer, designed with a 90-degree bend that enhances accessibility and adaptability, especially in posterior regions of the oral cavity where visibility and space are limited.

This instrument plays a crucial role in Class II restorative procedures, where a missing tooth wall must be temporarily replaced to allow proper placement of restorative materials such as amalgam or composite resin. The matrix band, when secured by the Tofflemire Universal 90 Bend retainer, forms a tight and contoured barrier that helps shape the filling material into the correct anatomical form.

The 90-degree angled design is the key feature of this instrument. It allows better adaptation around difficult-to-reach molars and premolars, improving ergonomics for the dentist and providing greater comfort during procedures. The 15 cm length ensures a balanced grip and precise control, making it suitable for both routine and complex restorative cases.

The instrument consists of a head that holds the matrix band, a body for structural support, and a screw mechanism that enables controlled tightening of the band around the tooth. This adjustability ensures a secure fit, which is essential for achieving proper proximal contact and correct tooth contour.

Manufactured from high-quality stainless steel, the Tofflemire Universal 90 Bend 15 cm is durable, corrosion-resistant, and designed for repeated sterilization. Its robust construction ensures long-term clinical reliability while maintaining precision and stability during use.

In clinical application, the matrix retainer is positioned before placing the restorative material and is removed after the material has sufficiently set. Proper use of this instrument ensures smooth contours, tight contact points with adjacent teeth, and accurate occlusion. This is essential for preventing food impaction, maintaining oral hygiene, and ensuring the longevity of the restoration.

Overall, the Tofflemire Universal 90 Bend 15 cm is an important instrument in restorative dentistry. Its angled design, precision control, and versatility make it highly effective for achieving anatomically accurate and functionally successful dental restorations.
