As I’ve been utilizing OMNICHROMA Circulate extra routinely in each day dentistry, my confidence in its capabilities has elevated. I’m regularly striving to do the least invasive dentistry I presumably can and having a direct composite materials that’s versatile throughout the broad spectrum of procedures is exceedingly useful. On this weblog article, I’ll share why and the way I exploit OMNICHROMA, OMNICHROMA Flow, and BLOCKER Flow in posterior restorative circumstances.
On this first case there have been small to reasonable sized cavities on the occlusal surfaces of enamel 18 and 19 (Fig. 1 & 2). After eradicating the decay the darkish reactionary dentin on the pulpal flooring was fairly seen on 19 and only a small space on 18 (Fig. 3). Every time I see any discolored dentin, whether or not it’s from decay or earlier restorations staining the dentin, I exploit the BLOCKER Circulate as a base layer to dam out the darkness from exhibiting by means of within the closing restoration (Fig. 4). The thickness of this layer depends upon the darkness of the world. The darker it’s the thicker the BLOCKER layer will must be. Nonetheless, the effectiveness of the BLOCKER Circulate is such that it doesn’t require a thickness that may attain the cavosurface margin. Typically I’ve to do that in a number of layers to maintain the curing depth of the fabric lower than 2 mm. However on the whole, the ultimate thickness of the Blocker layer will vary between 0.5-3.0 mm. As soon as the BLOCKER Circulate is accomplished, then I can use OMNICHROMA and/or OMNICHROMA Circulate to complete layering the restoration (Fig. 5 & 6). On this case, I made a decision to make use of OMNICHROMA Circulate and did so in a number of layers as effectively by inserting a bit of at a time on every cusp space as much as the cavosurface margin. If the preparation was smaller, then I’d’ve carried out it in a single or two layers solely. After closing mild curing, I used a advantageous grit diamond bur to create occlusal anatomy after which polished it (Fig. 7 & 8).
Within the second case, additionally on enamel 18 and 19, after the decay was eliminated, the dentin didn’t seem to have any darkness that required a layer of BLOCKER Circulate. So, on this case I solely used OMNICHROMA Circulate in the identical method described above, layering it into every cavity preparation in two or three layers to handle shrinkage stresses (Fig. 9, 10, 11, 12, 13, & 14). I felt comfy restoring completely with OMNICHROMA Circulate in these smaller restorations that weren’t deep or broad.
The ultimate case exhibits an instance of restoring bigger cavities on enamel 18 and 19. Each of those enamel had current giant composites which had been failing (Fig. 15). After the outdated restorations had been eliminated, the pulpal flooring was fairly darkish from reactionary dentin (Fig. 16). After air abrasion and positioning of the sectional matrix system, selective acid etching was accomplished adopted by Microprime desensitizer and Tokuyama Common Bond (Fig. 17, 18, & 19). The distal proximal wall was first established utilizing OMNICHROMA (Fig. 20) after which the ring and sectional matrix had been eliminated for simpler entry for subsequent layering (Fig. 21). BLOCKER Circulate was then used to cowl the darkish pulpal flooring which was carried out in two layers per tooth to keep away from every layer being too thick or broad for a single mild remedy (Fig. 22). On this case the OMNICHROMA BLOCKER Circulate layer was most likely about 1.0-1.5mm thick. OMNICHROMA was then used to fill the rest of the cavities in three or 4 layers per tooth (Fig. 23). I might have used OMNICHROMA Circulate however opted for OMNICHROMA this time due to the scale of the restorations and desired the upper power of normal OMNICHROMA. Occlusal anatomy was then created with a advantageous diamond bur and composite polishers (Fig. 24 & 25).
In abstract, I exploit BLOCKER Circulate as a pulpal flooring liner once I want to dam out any darkish areas of the preparation, similar to darkish reactionary dentin, or when changing outdated amalgam fillings which have stained pulpal dentin. In smaller cavity preparations I’ll restore absolutely with OMNICHROMA Circulate. In bigger cavities, I’ll use OMNICHROMA.
1 – Preop occlusal view of enamel #18 and #19 with outdated failing composite fillings.
2 – Preliminary removing of outdated composite restorations revealing recurrent decay.
3 – Accomplished cavity preparations exhibiting darkish pulpal flooring the place reactionary dentin responded to the recurrent decay.
4 – Tooth #19 exhibits the BLOCKER Circulate utilized and lightweight cured together with a small layer of uncured OMNICHROMA Circulate throughout the lingual groove space stuffed as much as the cavosurface margin. The BLOCKER Circulate is seen on the pulpal flooring. Tooth #18 had already been stuffed to completion with BLOCKER Circulate and OMNICHROMA Circulate.
5 – Tooth #19 stuffed to completion with OMNICHROMA Circulate earlier than mild remedy.
6 – Tooth #19 stuffed to completion with OMNICHROMA Circulate after mild remedy.
7 – Accomplished restoration after shaping and sharpening.
8 – Accomplished restoration after shaping and sharpening and after eradicating the rubber dam.
9 – Preop occlusal view of enamel #18 and #19 with decay in grooves.
10 – Tooth preparations after decay eliminated adopted by air abrasion.
11 – OMNICHROMA Circulate earlier than remedy.
12 – OMNICHROMA Circulate after remedy.
13 – Last restorations after closing shaping and sharpening.
14 – Fast put up op after eradicating rubber dam.
15 – Preop occlusal view of Enamel #18 and #19 with outdated failing composite restorations.
16 – Cavity preparations after removing of outdated restorations and recurrent decay. The pulpal flooring was darkish from reactionary dentin.
17 – Sectional matrix in place and selective acid etch approach was used.
18 – Microprime desensitizing agent scrubbed into pulpal flooring.
19 – Tokuyama Common Bonding Resin.
20 – OMNICHROMA positioned and lightweight cured on the distal proximal field of tooth #19.
21 – With the distal proximal wall now established, the part matrix system was eliminated to permit simpler entry to fill the rest of the cavity preparations.
22 – BLOCKER Circulate was added in two layers at 1mm or much less thickness till the darkish pulpal flooring was not exhibiting by means of. On this case tooth #18 and #19 had been about 1.5mm thick.
23 – OMNICHROMA was then sculpted and cured in incremental layers.
24 – Last layer of OMNICHROMA in place and cured.
25 – Last put up op occlusal view with rubber dam eliminated.
