- Apply dentin conditioner for 20 sec prior to placement of fuji VII.
- Avoid blowing air on fuji VII after placement.
Gold Standards have been 4th Gen. Bonding agents, but with advent of newer generation bonding agents (7th & 8th) the dentine & enamel bonding are as effective, in fact much better than the older generations & with less post operative failures, like sensitivity and debondings. When these new generation bonding system are used with “selective etching” technique, they have performed better & provides hassle-free excellent bond strengths.
The body of the restoration is then built with a restorative resin, which we want to be easy to handle, convenient to place, easily shaped, aesthetically good, fracture resistant, gloss retaining, margin concealing.
The material of choice is G-aenial composites which have all the above properties and complies with latest requirements (BPA free). Very few products have yet complied with this requirement. High volumetric content ensures more number of restorations per tube, thereby ensuring parity in terms of cost per restoration with other brands.
A standard composite will require material worth Rs. 70/- for a standard sized restoration and G-aenial will require Rs.90/-.
Also, currently, G-aenial composites provide an age-related choice of enamel shade which ensures unmatched colour matching and invisible aesthetics.
Using all four grits in sequential order will give a beautifully finished restoration that only requires a composite sealer to finish the procedure. Incomplete polishing leads to discoloration & staining. Polishing to be done with diamonds only – paste / felts / discs / buffs . Aluminum oxide impregnated discs ro be avoided .
These will seal off margins, smoothen micro cracks / roughness. They will increase surface hardness and provide glaze. Optiglaze from GC is an excellent option for glaze as well as minor shade corrections / characterization.
Light curing gun should have specified intensity & wavelength. LED lights give 1000 mw/cm2 intensity to start with. These are preferred as intensity does not decrease with time – Some clinicians opt for machines with plasma mode as a 3000 mw/cm2 intensity is theorised to cure to greater depths. Though question marks persist regarding the concept of bulk fill, it is proven that plasma mode ensures 3 second curing time.
The wavelength is where most machines fail to make the cut. The latest restorative materials require exposure to lower wavelengths as they contain proprietary initiators (Best absorption at 400 nm) CQ still absorbs best at 470 nm. Machines that have a wavelength rang of 400nm up to 500 nm ensures against failures due to incomplete curing.
Machines – 𝐅𝐋𝐀𝐒𝐇 𝐌𝐀𝐗 𝐏𝟑 𝐖𝐒 𝟒𝐖 (𝐥𝐢𝐠𝐡𝐭 𝐜𝐮𝐫𝐢𝐧𝐠 𝐩𝐞𝐧}- 𝐓𝐡𝐞 𝐌𝐨𝐬𝐭 𝐏𝐨𝐰𝐞𝐫𝐟𝐮𝐥 𝐂𝐮𝐫𝐢𝐧𝐠 𝐋𝐢𝐠𝐡𝐭 𝐨𝐧 𝐭𝐡𝐞 𝐌𝐚𝐫𝐤𝐞𝐭”. This comes with 5 Seconds cure and Broader Emission Spectrum – wavelength 390 – 470nm. High intensity and low curing time. It has long battery capacity, with low weight & noise.
The 10 points covered above in this special issue of power of 10 are points that have been discussed with experts and listed out. The theories behind various types of failures are well documented and the materials suggested are proven to be effective in these cases. All these recommended materials, equipment and instruments are tried and tested & come from leading dental companies of the world which are following the highest standards in manufacturing. There may possibly exist some optional choices. Readers are advised to study them in detail, before using.
