Clinical Case: Class IV Composite Replacement

Using 3M™ Scotchbond™ Universal Etchant, 3M™ Scotchbond™ Universal Plus Adhesive, 3M™ Filtek™ Supreme Ultra Universal Restorative, 3M™ Filtek™ Supreme Flowable Restorative, 3M™ Sof-Lex™ Contouring and Polishing Discs, and 3M™ Sof-Lex Spiral Finishing Wheels.

About the Case

Case Description/Background:
Patient was not satisfied with current anterior restorations (maxillary central incisors). Patient also expressed dissatisfaction with shade and surface texture.

Challenge:
Creating smooth and natural-looking restorations for patients who demand the highest level of esthetics can be challenging. The use of materials that mimic the shade and opacity of dentin and enamel is critical for success.

Initial situation

The patient was unhappy with the esthetics of their maxillary central incisors.

Preparation

After tooth preparation, the teeth were etched for 15 seconds using 3M™ Scotchbond™ Universal Etchant.

Selective enamel etch

3M™ Scotchbond™ Universal Plus Adhesive was scrubbed onto the prepared teeth for 20 secs, air dried for 5 secs, and light cured for 10 secs with the 3M™ Elipar™ DeepCure-S LED Curing Light.

Bioclear™

A silicone matrix was used to create the palatal wall with 3M™ Filtek™ Supreme Ultra Universal Restorative, shade CT, and light cured.

Results

The interproximal enamel layer was built with 3M™ Filtek™ Supreme Ultra Universal Restorative, shade A3E, and light cured. For the incisal halo, 3M™ Filtek™ Supreme Flowable Restorative, shade W, was used.

Application

Application of the dentin layer using 3M™ Filtek™ Supreme Ultra Universal Restorative, shade A1D, and light cured. For volume control, a Misura instrument was used to leave a 0.5mm space for the facial enamel.

Creation of mamelons and the application of a small portion of 3M™ Filtek™ Supreme Ultra Universal Restorative, shade CT, was added between the dentin layer and the incisal halo, and light cured, to enhance translucency at the incisal edge.

Final light cure

The final layer of 3M™ Filtek™ Supreme Ultra Universal Restorative, shade A3E, was applied and light cured.

Final restoration

Natural looking final restoration after finishing with 3M™ Sof-Lex Contouring and Polishing Discs and polishing using 3M™ Sof-Lex Spiral Finishing Wheels.
