An 18-year-old female presented with tooth No. 7 missing after a history of trauma. At age 7, she fell and the tooth avulsed. It wasn’t stored in any “liquid” or ideal environment, and when it was reimplanted, the results were compromised. No endodontic treatment was performed and at age 16, the patient lost the tooth; a temporary was fabricated. Subsequently, she had a bone graft using DynaBlast DBM Paste (Keystone Dental) plus a membrane barrier placed after decortification of the site; another temporary was placed. The patient again lost her temporary, and it was rebonded with resin composite at another clinic.

Looking for a longer-lasting treatment option, the patient came to the Advanced Program for International Dentists in Aesthetic Dentistry at NYU. Her oral hygiene was good; radiographic, oral cancer examinations, and medical history were within normal limits.

We decided to create a composite bridge with fiber reinforcement. The selected material was Ribbond bondable reinforcement ribbon, Ribbond-thm Thinner Higher Modulus 3 mm (Ribbond, Inc).

The use of fiber reinforcement provides distinct advantages in composite restorative techniques. The use of ultra-high molecular weight polyethylene (UHMWP) fibers is based on the improvement of the composite resin mechanical properties and behavior. To reinforce the restoration in multiple directions, woven fiber and meshes have been proposed, where isotropic properties are achieved.

Incorporated into composite materials, the fibers provide enhanced fracture resistance, indicating their application even when high stress is present in the oral environment. The 2 key reasons for using the fiber-reinforced composite for this case: minimal removal of sound dental structure and esthetics.

The treatment is described in the figure captions. After a painless, fast, in-office procedure, the patient left very happy and able to smile with new self-confidence.

This was not your typical patient who wanted to improve her smile. Even though she had upper anterior teeth that were out of position, she wanted only her front tooth restored to its original position.

FIRST LOOK: Triodent V4 ClearMetal Matrix System

Date: 07/26/2013 11:09am


Triodent’s new matrix system features transparent components for maximum curing without distortion.

Getting past the initial cure stage in a deep restoration with bulk-fill is a concern. If composite in contact with the matrix is still uncured when the matrix is removed, the disruption can be so great that the restoration may need to be done again from start to finish. Although this may not happen often, Triodent’s new V4 ClearMetal Matrix System insures against it ever happening at all.
