A radiograph revealed an incipient Class III lesion on tooth #7.
A saw was used to clear the contact of tartar buildup. This made it easier to place a rubber dam to help control moisture, in turn making the bonding procedure easier.
Decay was removed with caries indicator and a round carbide bur. A radius bevel was created using a fine diamond needle bur.
The teeth were cleaned, and the biofilm removed, using a prophy-blasting using aluminum trihydroxide powder (Bioclear® Blaster from Bioclear®).
A one-sided sanding strip was used to lighten the contact to aid in placing the matrix.
The finished, cleaned prep showed the radius bevel leading out to an infinity margin.
A Bioclear® anterior matrix was selected, A103HD, small incisor universal, .5 mm curve. The .5 mm curved portion of the matrix was cut away as it wasn’t needed in this case.
Total-etch technique (3M™ Scotchbond™ Universal Etchant) was used for the bonding procedure. The etch was placed, rinsed, and the restorations dried per the manufacturer’s instructions.
3M™ Scotchbond™ Universal Adhesive was placed, gently air thinned and cured with the 3M™ Elipar™ DeepCure-S LED Curing Light.* 3M™ Filtek™ Supreme Ultra Flowable Restorative shade B2 was injected into the matrix.
Warmed 3M™ Filtek™ Universal Restorative shade B2 was injected into the flowable causing hydrolysis to push the flowable out of matrix. The matrix was overfilled with composite to create a sprue that was cut away after curing.
Buccal and lingual sides were light cured for 10 seconds each. Matrix and wedge were removed. Restoration was contoured using a coarse 3M™ Sof-Lex™ Finishing and Polishing Disc. Once desired contours were achieved, restoration was polished (Magic Mix Pre-Polisher from Bioclear®) followed by a diamond impregnated polishing cup with water (RS Polisher from Bioclear®).
The final restoration was indistinguishable and had ideal interproximal contours. Composite cured against the mylar matrix provided a very high polish in the contact areas.
