To prevent contact of the adhesive with the adjacent tooth, another mylar strip was placed and adhesive was ap- plied. The manufacturer’s instructions for use states that you should rub in for 20 seconds, use a gentle stream of air for about 5 seconds, and light cure 10 sec- onds. My preference is to rub for 30 sec- onds, dry for 30 seconds and light cure for 10seconds. Fig. 5.

Third, the mesio-facial line angle, as well as the incisal, facial and palatal embrasures were defined.

In my experience, a speed of about 5,000 RPM using the diamond is ideal to create mi- croanatomy. Fig. 8. Next, I utilized the Sof-Lex™ Dia- mond Polishing System, which consisted of two steps.

ByDrMarcosVargas,USA Introduction Given my primary research inter- est in the area of dental materi- als—bonding, composite resins and esthetic dentistry—I’m always examining products with an eye to- wardsimpletechniquesandpatient- pleasing esthetic results. Recently, I was greatly impressed to discover a high-gloss finishing and polish- ing system that is effective for both anterior and posterior, direct and indirect restorations. The Sof-Lex™ Diamond Polishing System from 3M introduces a two-step approach that achieves a paste-like gloss with the convenience of a rubberized sys- tem. The flexible shape adapts to all tooth surfaces, producing a lifelike, high-gloss finish for the dental res- toration. Used with Filtek Z350XT Universal Restorative, the polishing system delivered excellent results while maintaining the integrity and anatomy of the restoration. When a young patient presented with a small anterior diastema, I used Filtek Z350XT restorative to close the dias- tema, then completed the case us- ing the Sof-Lex Diamond Polishing system, delivering beautiful esthetic results with a high gloss shine that greatlyimpressedthepatient. As a complete system, the Esthetic Restorative Solution from 3M com- bines the time-tested Filtek Z350XT restorative with the new Sof-Lex Diamond Polishing system to im- part a very natural-looking gloss in a technique that is kinder to gingival tissues when compared with con- ventional discs. It brings together the diamond paste-like polish in the convenience of a rubberized system, which I can appreciate in my prac- tice. CasePresentation A young female patient presented, after orthodontic treatment, with a small anterior diastema, mesial to the right lateral incisor (Fig. 1). The patient’s main esthetic concern was to eliminate the space and increase the size of the lateral incisor. Addi- tionally, to ensure optimal stability of the orthodontic treatment, proxi- mal contact among all anterior teeth is desirable. Isolation with a rubber dam pushed the gingiva apically to provide accessibility to the cervical areaandallowedmetocreateproper anatomical contour and emergence profile (Fig. 2). The patient presented with a small anterior diastema. (Fig 1.)
