MeshMixer: Orthontic Fixed Retainer

[@Berberedzo]

I subbed last week and OMG is this video helpful... Really loving the content so far, please keep it up! Great video, thanks Doc!

[@bgrutterdds]

My pleasure. Thanks for the kind words.

[@yvonnewongdds]

I like your explanation better than Wally’s. Your voice is so clear and the pace is perfect.

[@bgrutterdds]

We all have different workflows and thought-processes. I'm glad explanation was of help to you.

[@dvomang]

I have placed 3 of these now since Wally posted a video. I like them so far! I am considering try to have a built in seating guide on the occlusal.

[@bgrutterdds]

I will have a video on that tomorrow. Already tested it. Just need to head to bed. 😂

[@bgrutterdds]

I lied. It's up. I couldn't wait. Lol

[@TanjaSchoffer]

Thank you for your great Video and for always sharing your knowledge. I hit "b" before "tube handle" to get smooth nice tubes between.

[@georgeslab]

Thanks for the very informative video. What material do you suggest for durability ? Which brand ?

[@simisilver1084]

thank you for making this look not too difficult!! We need a course for lab techs - or I just want one for my kiddo to be my lab tech lol

[@orthodudeness]

Is it possible to re-set the default numbers in Mesh Mixer? Trying to set a constant default number for model wall thickness to 3 mm. It always starts at 2mm. Every model I do I need to reset to 3mm. Thank you for all these great Mesh Mixer videos!

[@bgrutterdds]

Nope. At least not that I've been able to find. Annoying that the preferences are pretty minimalist in MeshMixer.

[@orthodudeness]

@@bgrutterdds True. Being a small lab, just a few simple pre-set adjustments would save a little time. Short, me, from LA. Moved to the forest in Vida Oregon in 92. Ortho only, most all FedEx and UPS in and out. Printing models has saved a lot on shipping costs. Covid was very helpful as it gave plenty of time to learn all needed for resin printing models. I have 5 Epax printers. (X10) Thanks for your quick response!

[@orthodudeness]

@@bgrutterdds Is there another program you might suggest for just basing models? I get stl files emailed to me.

[@bgrutterdds]

@@orthodudeness yeah, BlueSkyPlan is the most efficient. Not as easy on the trimming and cleanup, but you can get pretty quick. Adding a base takes 1 button click. If you like hollow models, also just 1 button. Hard to beat that simplicity.

[@orthodudeness]

@@bgrutterdds l look into that now. Thank you. Have a great day!

[@kevinknowlton853]

Thanks for the video. If we just placed pads on the canines and bonded to the canines only, do you think that Onx has the flexural strength to resist fracture?

[@bgrutterdds]

I do not. Most people that are doing this are using OnX Tough, I understand. I'm not currently doing them, the video was just for demonstration since people were looking for options on design. However, I would not recommend doing it at all for a 3-3 (canine-canine) fixed retainer. That definitely needs to be metal in my opinion.

[@dremadesmeir2928]

Hi do you have any idea how we make tunnel on the resin printed retainer that we can add wire in the retainer to make the retainer mor resistant

[@bgrutterdds]

Since AWs have sharp edges, it would be very difficult. Also, printing such a small lumen would be most likely to be occluded.

[@jamiekane4182]

Dr. Grutter, have you ever tried this on the upper centrals? I placed one this week but the bridge connecting the teeth broke. I'm wondering if I should go over the incisive papilla so it can be thicker but not get in the way of occlusion.

[@bgrutterdds]

Honestly, I'vestill not seated one. Like I said in the video, I was only making it as informational for those that would like to. I have a case coming up that I might use it on, but I'm a larger user of removable retainers rather than fixed.

[@jamiekane4182]

@@bgrutterdds Thank you for the reply. I have placed two this week (one upper and one lower) printed with SprintRay Crown resin and both broke with in 24 hours. :(

[@bgrutterdds]

Sorry to hear that. I'm thinking OnX Tough would be more resilient.

[@berras1001]

Do you know a suitable material from Formlabs by any chance? I have formlabs printers.

[@bgrutterdds]

That's tough to say. I believe they have a definitive Crown bridge resin. Possibly white labeled from Bego? I would think that would be your best bet.

[@kimberlyvanhouten5166]

What is the bonding protocol?

[@bgrutterdds]

Same as with traditional fixed retainer. Etch, Bonding Agent, and Bracket cement

[@TheKiteboy100]

What material do you use to make these?

[@bgrutterdds]

Most are using SprintRay OnX or Desktop Health Flexera.

[@SzaraDentalLab]

Thanks for sharing. Now go put baby to bed!

[@bgrutterdds]

Hahaha
