Clinical Case: Restoring Worn Teeth and Closing Black Triangles Using the Bioclear Method

Using Bioclear™ Black Triangle Gauge, Bioclear™ Matrices, 3M™ Scotchbond™ Universal Etchant, 3M™ Scotchbond™ Universal Adhesive, 3M™ Filtek™ Supreme Flowable Restorative, 3M™ Filtek™ Universal Restorative, and 3M™ Sof-Lex™ Contouring and Polishing Discs.

About the Case

A 48-year-old male, in pre-treatment for oral rehabilitation, presented with black spaces, a high degree of wear on his mandibular incisal edges, and non-carious cervical lesions. Using the Bioclear™ Method in combination with 3M Restorative Materials, it was possible to restore this case in a single office visit. This approach provides a simple, fast, predictable and non-invasive solution for what would have otherwise been a very difficult clinical challenge.

Initial situation

After biofilm removal, the Bioclear™ Black Triangle Gauge was used to determine which color-coded matrix to choose.

Preparation

Color-coded matrices were selected to correspond to the Black Triangle Gauge and seated sub-gingivally.

Selective enamel etch

The teeth were etched with 3M™ Scotchbond™ Universal Etchant with the Bioclear™ Matrices in place.

3M™ Scotchbond™ Universal Plus Adhesive

3M™ Scotchbond™ Universal Adhesive was applied, rubbed for 20 seconds, air dried for 5 seconds, and light cured for 10 seconds.

Results

After a second layer of uncured adhesive was placed, 3M™ Filtek™ Supreme Flowable Restorative, shade A2, was injected into the contours of the matrix but not light cured.

Application

3M™ Filtek™ Universal Restorative was added using the injection molding technique and light cured.

After using a spatula to shape the restoration within the matrix, the composite was light cured from the facial, incisal and lingual surfaces and the matrices were removed.

Final light cure

Excess composite was removed with a fine diamond bur.

The composite was finished and polished using 3M™ Sof-Lex™ Contouring and Polishing Discs.

Final results.
