MOD Ceramic Onlay #3 Acadental | Dr. Richard Stevenson

[@rodrigocartens7563]

Absolute genius! The knowledge Dr. Stevenson shares with us in dentistry, in my opinion, is comparable to the renaissance schools of sculpture. Teaching with finesse how to reach perfection!

[@StevensonDentalSolutions]

Too nice Rodrigo!

[@franklinsachin1]

Can't agree more 👍🏻

[@niloufarkoohestanian1407]

Thank you Dear professor. I was so blessed for being in your courses at UCLA like posterior ceramic mastery.

[@StevensonDentalSolutions]

Thank you doctor!

Beautiful preparation and explaination Dr Stevenson! I’m glad to have accidentally found you on KZbin!!

[@StevensonDentalSolutions]

Cool! Thank you.

[@sharonj2349]

Your videos are great! Clear demonstration and I appreciate your succinct explanation of the "why" not just the "how" of what you are doing. Would you please make a video about temporizing inlays and onlays? Thank you!

[@StevensonDentalSolutions]

For sure and thank you!

[@pmelladonavarrete]

Doc, it's so relaxing and useful. Appreciate it so much. Love from 🇨🇱

[@hierinmeinenaugen]

Thank you, this is beautiful. Will have an onlay procedure soon and I will utilise these techniques.

[@StevensonDentalSolutions]

Awesome!

Thank you Doc!

[@redflower5004]

Hi doc, first of all,Iam so blessed of you please ,can you do videos about the basic steps to prepare abridge? Final,there is away we can connect with you?? sorry for long🤗

[@StevensonDentalSolutions]

Will do, thank you.

[@abdullahalhammadi8012]

Thank you Doctor for the video. I got a question here. If tooth is RCT treated with a good tooth structure Is it better to go for a crown or an onlay? Thank you

[@StevensonDentalSolutions]

Conservation of tooth structure is the likely the most important factor when considering restoration longevity, hence the onlay, when possible.

[@alokpol3312]

Greetings from India. Towards the end you mentioned the prep is not ideal. Can you please share the shortcomings to make it ideal. Thanks.

[@StevensonDentalSolutions]

minor deviations - minor roughness, minor uneven extensions - still 5/5 but not quite the best I can can do...Thank you!

[@alokpol3312]

@@StevensonDentalSolutions i think it is more than most can imagine and achieve. U have been an inspiration for many like me who love Restorative dentistry. Your critical approach even towards your own preparations is commendable and something to be learnt. look forward to the next prep.

[@diesel9442]

Can you kindly explain the tapers of the box, Is it diverge 6-8 degree? and is it same for a standard amalgam class 2 cavity ? Thankyou in advance

[@StevensonDentalSolutions]

Diverge about 6-10 degrees total and for amalgam it will converge on the functional cusp wall and make a 90 degree angle with the non-functional cusp wall...

[@1smail.khaled]

Hello doc 😊 i have an idea ; we want to make a discussion group to share our preparations or any work we learned from your amazing talent , we want your comment on our work this can encourage us or make us learn how to improve it .. thank you very much for every video and waiting for new amazing ones ❤️

Sounds great - let me know where you post

Great video, as always. Will you be doing any videos regarding Partial or Complete Denture fabrication?

[@StevensonDentalSolutions]

I have an RPD design series on my website - so maybe later...Thank you!

[@dinojubalsalvanera7997]

@@StevensonDentalSolutions I will definitely check it out, thanks!

[@hamzaahmed5694]

Amazing work, what was the depth for the Proximal box areas, 2mm?

[@StevensonDentalSolutions]

The axial depth is usually about 1-1.5 mm and the height of the axial walls ranges depending on the contact area, tooth height, and the pulpal depth. The box height is not so critical for retention but certainly helps for resistance form.

[@romanstadnitchi456]

Hello Dr.Stevenson, thank you a lot for all your videos, but i have a question in this particular case, why you are doing onlay MOD instead of inlay MOD, why it is necesary to reduce significantly the cusps when we could do this in more conservative way by doing inlay? Greetings from Republic of Moldova

[@sazomar4569]

Same.question

[@nainachopra1983]

hi dr stevenson...i m new to your channel...but wonderfully explained concepts. i have been giving onlays with flat occusal prep for may years...but this is what i wanted to learn.....thank u...for an endo treated tooth would you give a shoulder /wrap around design on non functional cusp as well

[@StevensonDentalSolutions]

Hi Doctor, welcome to the channel. I would usually wrap the non-functional as well - grab the walls with resistance form increased. Thank you for the great question.

[@pedramnamiranian3764]

Wasn't there any finishline for the buccal cusps? I mean where the onlay is going to terminate on the buccal cusps?

[@StevensonDentalSolutions]

Butt joint finish line - no cap used here - it’s a non-functional cusp. Only requires 1.5 mm butt

[@hamzaahmed5694]

Thanks Doc! When would you think about breaking the contact points for These MOD onlays?

[@StevensonDentalSolutions]

It's a must. Usually, 0.5 to 1.0 mm is about right to allow for lab work and finishing.

[@vevodj]

Great video, like always, i wold like to know how can I buy those burs. I live in México. Thanks a lot doc, salute from México and Italy

[@StevensonDentalSolutions]

We can ship to Italy (stevensondentalsoutions.com)

[@annashipilova5327]

Hi Dr S, If one or both non functional cusps are carious too should they be capped in the same way as the functional cusps with a shoulder finish line? Thanks for the super helpful video!

[@StevensonDentalSolutions]

Yes - you got it

[@hamzaahmed5694]

And would Ceramic Onlay be your go too, for Root canal treated teeth? over Full Gold? thank you :)

[@StevensonDentalSolutions]

This would depend on the remaining tooth structure, occlusion, parafunction, history of previous failures, etc. I always try to perform the least most invasive procedure that will provide the most predictable results. The evidence here is a moving target so clinical judgment is your best position from which to plan.

[@hindzizi35]

Hello doctor, thanks for your vidéos, i have a question: in the case of mandibular molar, the preparation for onlay will be the same

[@StevensonDentalSolutions]

No - the shoulder will be on the buccal rather than the lingual.

[@hawrazhede]

Thanks dr. Are there any substitution for hand instruments?

[@StevensonDentalSolutions]

Thin burs to remove undermined enamel...

[@kaanasvaroglu3886]

thank you for the video. may I learn the camera end the lens that you record with?

[@StevensonDentalSolutions]

Canon HF G50 Vixia with Vivatar +2 lens magnifier.

[@stella444]

I was wondering if you would be doing any videos on class V preps?

[@StevensonDentalSolutions]

Eventually - probably on actual patients once my dental op studio is set up.

[@stella444]

Stevenson Dental Solutions awesome! Can’t wait 😊

[@StevensonDentalSolutions]

@@stella444 You got it!

[@sherafati]

Thank you, what if the tooth is damaged? What restoration material could be used to build a core to perform the prep on it?

[@StevensonDentalSolutions]

Usually bonded composite - dual cured.

[@diesel9442]

Also cementation of the onlay? would you use dual cure cement?

[@StevensonDentalSolutions]

Yes I usually do - I use RelyX Ultimate most of the time. The warm composite approach is reserved for high esthetic demand cases and translucent ceramics.

[@D3r3k3r3D]

Just a random question. I've been having some issues with drilling maxillary anterior teeth from the palatal aspect, and i've been getting a lot of water splash on both myself and my manikin. In order to maintain proper angulation, it forces myself to keep an angle which results in a spray of water upwards. Any tips?

[@StevensonDentalSolutions]

Other than turning the water flow rate down, try tipping the head away or towards you and position the mirror 90 degrees to the handpiece head - looking from the side as you cut. As long as your bur position is set in advance with a good finger rest, you'll be in the correct place and the water will not be as much of an issue. Let me know how this works for you, Best, Dr. S

[@mahalak4383]

This mod.. what if we want to give onlay on endodontically treated with no or only one proximal caries, do we still need to break contact on the unaffected side ?

[@StevensonDentalSolutions]

Not always, but usually. It depends on if you can cap the unaffected marginal ridge above the contact area and still have access to cleaning the margin. If it enters the contact area, you'll need to break contact. Also, for endo-treated teeth I would cap both buccal and lingual cusps.

[@mahalak4383]

@@StevensonDentalSolutions So if we are reducing unaffected marginal ridge, and while reducing, margins enters the contact area, we will involve it?

[@danimari516]

at my dental school, we're not allowed to use hand instruments during our practicals. Sad days

[@StevensonDentalSolutions]

Yes, very sad indeed.
