The Candy Coating technique a rapid way to finish your guards to a high shine. One technique we teach at The MOD Institute Occlusion Level 1 class

Curious if you have any recommendations on how to design supports on the buccal surface of the splint vs the AI designed ones generated by sprint ray? What density of supports/how far apart can they be? I’d love to eliminate supports on the occlusal surface. Thanks for the video - super helpful.

What do you reckon is the different is the level/comfort of the fit of a printed appliance vs a vacuum formed one?

May I ask how do you clean the brush after the resin application?

I try this technique with my crown using sprintray ceremic crown material and it looks pretty nice. Right out of the printer and no polishing. Great technique! Thanks.

Try putting ONX Tough on the Cermic Crown. Works even better

Wally, with the Otoflash, how many cycles are you programming in for each cure cycle? I am trying this on Primeprint Splint but can't get any information on the IFU for that material and have asked for information on the DS PPU's curing cycle, but no information as of yet to try and translate over to the Otoflash. Thank you!

Typically 1000 flashes per side is normal. So 2000 flashes. Then put in glycerin and do another 1000 each side

Do you always break away the support nibs prior to curing. Everytime I polish off the nibs, it takes away the clear look that I am looking for.

@wallyrenne Жыл бұрын

Just after washing polish nubs

Hi Wally, what is your adaptation value in exocad for candy coat technique?

@wallyrenne 28 күн бұрын

Occlusal adaptation is 50 microns out of occlusion.

@natehenderson3828 Жыл бұрын

Did you polish off the support nibs? It looks like you broke them off cleanly. I print using Keystone Soft and always need to polish after cutting off the supports.

@wallyrenne Жыл бұрын

Yea depends on the material and printer but definitely want to make aure they are smooth

@ninanovak6771 Жыл бұрын

So Dr. Wally if you still have nubs from the supports when you would you smooth those? Also the step when you spray with alcohol and dry is that in place of placing of putting it in the wash unit?

Do you reuse the glycerin or dispose after each use?

@wallyrenne Жыл бұрын

Reuse if same print material. About 10 times

Sometimes I have little bubbles on the inner surface of the nightguard. What do I do wrong? Thanks for your help, awesome content and best wishes from Germany!

Try to keep it very thin. Also cure it first. Before curing again in glycerin

ive tried this technique several times and its just not working for me, im using the nightguard flex i apply the same resin very lightly on the occlusal surface then place it in the procure for some reason it just will not cure it comes out still sticky before i place it inside the glycerin and once it comes out the glycerin it washes off but leaves a semi sticky clammy surface. please any help would be appreciated. Thanks' in advance

@wallyrenne 7 ай бұрын

It will always be sticky out of the procure before glycerin. It’s the oxygen inhibition layer. The point of the glycerin is to remove and cure that slime layer. Make sure to rub the glycerin into the guard before placing into glycerin. Also notice I tack cure before placing in the procure. That’s a critical step.

@jamesmallory8648 3 ай бұрын

After painting the glaze coat, could you skip that first "pre-curing" step and go straight from painting the glaze on and into the glycerin for a full cure cycle?

@wallyrenne 3 ай бұрын

You have to at least tack cure the resin so it’s hard before it touches glycerin

@JCDentist 8 ай бұрын

Could you please link the brush, or at least describe what type of brush you would need to look for that has the ideal properties? I know you got this one on Amazon and it doesn't shed bristles, but given that information I am unable to find this exact model. I'd like to ensure I get a brush that has ideal stiffness and wicking, etc. Thanks

Do you ever cure with nitrogen? Would it simply eliminate the second cure with the glycerin?

Yes they are interchangeable

these guards are a lot thinner than the ones designed by sprintray. i'm going to have to ask them to thin it out a bit

"It takes more than double curing to make the material brittle" with all due respect; would you mind proving this take?

Wow. You are perfectly capable of doing a pubmed search and downloading the literature and reading it. I am not your personal library. It is well known that increasing cure times increases color stability, hardness, flexural strength, biocompatibility and wear resistance. Have you been living under a rock? Here are a few you should read that look at extra kong curing times for a variety of materials: Al-Dulaijan YA, Alsulaimi L, Alotaibi R, Alboainain A, Alalawi H, Alshehri S, Khan SQ, Alsaloum M, AlRumaih HS, Alhumaidan AA, Gad MM.
