Injectable Technique

Case 1: Injectable Technique – Composite Veneers – Minor Reshaping for Better Esthetics​

In presented case 6 composite veneers were made on upper maxillary teeth with injectable technique. Everything was driven by the wax up, and the beauty of this technique is predictability of final results, great symmetry and possibility to achieve marvelous primary, secondary and tertiary morphology.

After facial analysis models were scanned, and digital wax up was made. Based on the wax up Mock up was done, to check guidance, functional parameters, esthetics and phonics.

After few minor corrections final digital models were printed as set of 2 wax ups. One with every second tooth waxed up, and another one in full morphology. Based on those two, silicon indices with transparent silicone (Exaclear, GC) were made. In this configuration clinician can follow single veneering concept for perfect stabilization of silicon index intraoral, and great control of excess material on adjacent teeth with better emergence profile of restorations.

Due to low lip line and fillers, her gums are not visible in the forced smile so this asymmetry in the soft tissue around central incisors was left as it is. Teeth were cleaned, etched, dental cord was packed in initial part of the sulcus for preventing fluctuation of flowable composite subgingival and sulcular liquid in field of work. Adjacent teeth were isolated with teflon tape and after full protocol of adhesion (G-premio Bond, GC), flowable composite G-aenial Universal Injectable, GC was injected and polymerized directly on the teeth. A1 shade was used for incisors, while canines were done with A2. Glycerin gel was used for final polymerization as insurance that whole oxygen inhibited layer was polymerized. For finishing and polishing protocol scalpel blade no 12, Epitex stripes, fine diamon polishing bur and spirals were used.

Everything was done minimal invasive without tooth preparation. To get long lasting results, function needed to be planed in correct way. That’s why we included canines in our plan to get canine guidance and avoid some harmful contact and forces on incisors that could end up with chipping of our restorations.

In the article you can find before, after, 1 years and 2 years follow up. Some modifications such as cord placement, cutting silicon index, double set of wax ups, were done in this case compared to original described protocol.
