DentXpin^TM

How to Use It

Step-by-Step Guide

DentXpin^TM enhances the shear bond strength between composite resin and tooth structure, creating a stronger, more durable, and permanent repair. By mechanically and chemically anchoring the restoration to the tooth with a custom fiber optic pin, it transforms the approach to tooth repair and significantly improves restoration longevity. Suitable for both anterior and posterior applications, DentXpin^TM provides a reliable long-term solution for fractures of all sizes and works with any anchoring or restorative material on the market.

01 Chip

Chipped Tooth – how many of these do you see and repair without long-term success?

02 Add Floss to Pin

Be sure to attach floss to the handle of the pin to ensure it is not swallowed or aspirated during the procedure. See the picture above.

03 Inserting Pin

Using the custom bur provided in the kit, drill the hole to the desired depth and rinse. Using any bonding system, coat the hole, tooth, and glass pin with bonding agent. Place a drop of flowable composite on the tip of the DentXpin^TM. Insert the pin into the hole while wet, then cure both the pin and the tooth.

04 Score Pin with Bur

Using the custom bur, score the DentXpin^TM. Cut to the desired length.

05 Pin Placement

The tooth is now ready for restoration with any composite system. The pin improves light-curing depth and shear strength.
