    Does anyone print night guards?

    If so, which printer do you use?
    Did you face any problems? (Such as guard not fitting in patients mouth, breaking)

    We recently started printing them on a ND 5100 with ortho resin. They fit great once you have your CAD settings dialed in. Only been doing it for a few months, but none broken so far.

    Thank you for your reply!
    I see...we are testing a few but some keeps breaking...
    What are the parameters you use? Is there any minimal thickness we must follow?

    Also-How do you polish your guards? Any tips and tricks?

    I'm going to start printing them.
    Can't really tell the difference other then the color of the Next Dent Clear and Blue.

    Can you provide any insights? $400 for a 1 liter bottle. How many guards can you get out of bottle? Including the material for the supports.

    We've only been printing for two months or so. I can't give you an average per bottle yet.

    The design is more like a deprogrammer from 1st premolar to 1st premolar on the upper arch.
    The thickness is 2.5-3 mm.
    They are finished with Scotch bright wheels in a hand piece and polished with fine pumice and fine acrylic polish on a lathe.

    I'll have to post the parameters tomorrow when I get to the lab.

    I thought that printer was going to the boss' son.

    That's where it is, but we design everything that goes into it here and then finish it here as well. Guides, splints, placement jigs, prototypes, etc.

    Thanks for the information.

    Not sure how popular hard night guards are.
    It seems like thermo elastic appliances are more popular.

    I have been looking at Erkodent as well. It's about more of an investment to buy the machine.

    Ok i pay only 189 Euro for ND clear so 1.15 Euro plus maybe 1.15 for residual 2.30 not bad Lol

    Cadfan, what are you using to remove the support ends and finish the surface?

    that time the hardest challenge old hard metall burr to smoothen and sand paper but harder to polish too i hope less supports with non FEP film in the near future therfore less work next project .

    I take my nightguards and splints out of the mill and polish :D:D:D

    The ones we have milled polish easily. Can the mill produce 5-6 splints biteguards in less than an hour? :D

    Doesn`t matter to me, i mill splints during the time the mill is free. It`s a part of organisation in my lab. Time is money, especially my time :D:coffee

    bigbrush is right milled is easier but the mill cost . the patient
    vs doc can choose basic product or upcharge premium product milled ;):D

    Just started with Asiga Max UV and Detax Freeprint Ortho, haven't had my training yet, but I've got a manual;), printed three bite splints and two surgical guides.
    One of the splints was from an old file for me, fit was great. Takes around 10 grams per splint.
    It is easier to polish a milled splint so I will definitely try the scotch bright wheels.

    Anybody know how/where to get the GC Temp PRINT resin in the states?

    I see, I'll keep that in mind. We've been testing out few cases but can't seem to get the right fit and bite - since the material is so rigid.
    Maybe i'm doing something wrong with the design...

    Thank you for the tips on polishing!

    Here are the bite splint bottom parameters we use.

    Post a screen shot of where you are marking the splint borders after the model blockout.

    Thank you! We use exocad too. I will try using that parameter right away.

    The offset depend the printer you use, also the most important is to set the correct profile resin and calibrate at xy axis. Example, mine printer need 0.06 offset
