Hi Dylan, at 6:45 to 6:50, you said that the front teeth should be positioned "3 to 4 quarters" behind the front of the tray wall. Could you please clarify what unit were you referring to regarding the "3 to 4 quarters" distance? Another question, at 16:10, did you mean that we should use thumbs/fingers to hold/support the tray lightly, not applying any force upward (for the upper impression) or downward (for the lower impression)? But initially we should push the tray onto the teeth to make sure the teeth sink in for the putty to cover the gum line, right? Is it that after the initial push, we could just lightly support the tray during the 3 minutes cure time? Please confirm if my understaning is correct. Thank you so much!
Great question. I am referring to the physical quarter coins. Basically, you want to give your front teeth enough room behind the tray wall to avoid breakage. Once the impression is completely pushed up (for upper) or pushed down (for lower), you want to hold them lightly to avoid moving the tray and cause distortion of the impression material inside the ray. So yes, your understanding is correct.
@@JSDentalLab Thank you, Dylan! So I measured it and the thickness of 3-4 quarters is about 5-6 mm. Does that sound right to you? Another question I have is about how much to press down initially, especially if I want to make sure that I cover all the gum line, even for my longer teeth. Because when in action, it is very hard to judge how much I should press down to cover the gum line, is it okay to press up (or down) all the way until the biting surface of my teeth touches the tray? I think I did that in one of my failed attempt (due to off-center) and the resulted impression had very thin putty around some of the cusps of my teeth, and even ended up with tiny breakage (around 1 mm across). Would that be okay? Or do you have any other tips for me to make crisp gum line impression? Thank you!
@@maomao6860 5-6mm is about right, and about 4-5 should be sufficient. You should push down all the way until your teeth can feel the bottom of the tray slightly. The key is to push down or up smoothly in one direction to avoid distortions.
I have pronounced spurs in the area behind the front lower teeth.I don't want to use the upper stray because I'm missing some molars.Will it be too painful/difficult to obtain GOOD impressions of the lower teeth due to these spurs?In other words, does the tray allow for these (Mandibular tori) in order for me to make a proper impression of the lower teeth?
I purchased this mouth guard kit a year ago, and I couldn't try it out cause I was pregnant and everything made me nauseous. If I send out my impression now, do you think the company would still accept it?
As long as your bridge is done well, it will not pull it out. Impressions are done on dental work in dental offices all the time. But dental work deteriorates over time so if the foundation is not strong, there is a risk of it being pulled.
This seems really complicated. It’s too easy to make a bad impression according to this video. The examples of the bad impressions are ones that I think look good so I most likely would mess up mine. I’ll probably find another option.
We are sorry if this long video made the impression process seem complicated. That said, I am happy to report that we made a short 4 minutes video that should help demonstrate some of the key points of the impression process. I think you'll find it quite intuitive after watching this video :) ineedtalents.wistia.com/medias/3c0y9dp61m
This video needs to be shortened. Simplified. This is professional?! This is suggested?! I am so frustrated at the lack of directness. The run around. The LENGTH.

Hi Kim. It should not pull off crowns that are bonded well. But like any dental work, crown can deteriorate and become loose overtime, especially if you grind and clench on it. As long as the bonding is still strong, the impression process not be a problem.
Excellent demonstration! Thanks for providing high quality mouth guards at reasonable prices.
Thanks for the comment, Steve :)
Welcome to JS Dental Lab.
This was a very helpful video. Thank you!
Thanks for the feedback :)
Great video. Very helpful!
I am glad to hear that :)
Very informative and thorough. Recorded in a studio as well? That's going the extra mile... Nice work!
Thank you for the comment :)
I am glad the effort paid off!
Really appreciate all the tips and insight - I'm a lot more comfortable about the process.
I am glad the video was helpful!
Thanks for the video
You bet

Hi Carolyn. We can custom the tray for your mandibular tori :) You can reach out to our support and request it.
What is the proper way to remove the impression mold after the 3 minutes? Just pull straight down? I'm nervous about doing a bad job 😢.
Yep. You can just pull straight down. After 3 minutes, the putties are hardened enough for any distortions to take place 😀
What do you do when you receive bad impressions? Can you still make a night guard with them?
A bad impression leads to ill-fitting guard. While we can fix minor distortions, we do send out extra materials free of charge so you can retake it.
I purchased this mouth guard kit a year ago, and I couldn't try it out cause I was pregnant and everything made me nauseous. If I send out my impression now, do you think the company would still accept it?
Absolutely! We'll accept it.
If you need more impression materials, let us know and we'll send them out free of charge.
What putty is that
Will this pull out my bridge? I’m thinking it might after holding it for 3 min. Is the putty sticky like taffy?
As long as your bridge is done well, it will not pull it out. Impressions are done on dental work in dental offices all the time.

Hi Jenny. We do have a much shorter version. Here you go: ineedtalents.wistia.com/medias/3c0y9dp61m
This is way too long I’m not watching 20 minutes. Going back to the booklet for instructions

Will this pull out crowns? Have 2 on molars.
Hi Kim.
It should not pull off crowns that are bonded well.
But like any dental work, crown can deteriorate and become loose overtime, especially if you grind and clench on it.
As long as the bonding is still strong, the impression process not be a problem.
I'm worried about the same thing!
@@beautifulhope861 Yea. Like I told Kim, as long as your dental work are in good condition, it won't be a problem.
