- เผยแพร่เมื่อ 30 มิ.ย. 2024
- Because of its longevity and organic aesthetics, porcelain-fused-to-metal (PFM) crowns are among the most well-liked and dependable restorations. This material closely resembles the appearance of a genuine tooth using a cast metal substructure veneered with porcelain. In this video, Dr. Richard Stevenson demonstrates about PFM Preparation on Mandibular Canine - Acadental Tooth #22

Thanks for watching! - ภาพยนตร์และแอนิเมชัน
Thank you so, so much for this! As a UK dental student, a nice slow demo like this is exactly what I need to cement my knowledge. Thanks again!
Thank you!
True doc ! Very easy to loose orientation while doing tooth prep without references. Your method helps many beginners.
Thank you
Awesome video Dr. Stevenson! Love what you’re doing
Thank you!
Very nice of you to say - thank you
Your videos are so precious. Thanks for your efforts. Everyone is amazed by my crown preps now because I am strongly following your steps.
Thank you! My pleasure, Dr. S
I'm happy to see such an awesome result 😂❤️
Thank you doc! I improved a lot after watching and applying the techniques 😊
Awesome!
Your videos are so informative! Thank you!
Thank you!
Dr.stevenson you are doing great dentistry 👍..learn alots by these😍
Thank you!
May God bless you and fulfill all your wishes🤲🌸 thank you very much doctor
Thank you!
Such perfection is hard to simulate; nonetheless, I have improved quite a bit from observing your novel methods. It would be nice to see more amalgam restorations and composite restorations on the maxillary and mandibular molars. Thank you!
Will do! Thank you.
Very informative and conceptual.
Thanks
Thakn you - all the best, Dr. S
Great job
It would be a great idea to do a sample/mock WREB exam. I think a lot of us would appreciate it! Thank you, Dr. Stevenson.
I will do this - great idea.
very nice!
thank you Doc.
Thank you Doc
Great demonstration 👍
Thank you! More to come.
We watch your videos in my fixed restorative (crown) and operative courses! Just finishing my D1 year. Thanks so much, these videos have helped so many of us!
Cool - what school?
Thank you
Awesome preparation dr
Thank you - take care.
You are great teacher. Learned a lot from you. I am wondering if you can also teach us on how to repair accidental tooth damage of adjacent teeth
That's a good topic and I will do this for sure!
Wow such a fine and perfect cutting Sir ..Need to learn so muchh from you...
Thank you Doc!
Thanks♡♡
This is my go-to tutorials! Thank you, doc!
My pleasure, Doc!
Working that hand piece like butter!
The chef dentist - thank you!
Super sir
Thanks alot Dr..please can you make a video about the steps of crown or a bridge in clinic ...from preperation ..impression till insertion 🥰
Will do eventually!
Thank you for the suggestion.
Amazing
Very nice of you! Thank you, Dr. S
Dental student from Egypt like all your work that help me alot .. thank you and wish traveling to achieve more benefit
Great!
Nuevo video wujuuuuu! 🤩
Thank you!
Thank you so much for the great demonstration! some clinicians request a bevel chamfer from misial to lingual to distal and keep shoulder finishing line on buccal for PFM preparation, they say it is easier for the lab to finish the metal on a bevel? what do you think? Thank you
Bevel or chamfer are both relatively easy to finish metal to. Thank you
very neat. My question is whether you use reduction templates for teeth that are slightly misplaced Instead of the T or S or finish line preps - TIA
Yes, all the time. I reduce the tooth on the cast and wax it to ideal contour, then use the putty template in the mouth.
Hi Dr.
Dr. What is the disadvantages of making one type of finishing line all around the tooth (shoulder or chamfer)?
Since the lingual margin is going to be metal, a slip joint is required for optimal seal and this requires a bevel of at least 45 degrees via a modified chamfer or a shoulder bevel. The ceramic area will usually be a porcelain butt joint, which requires a shoulder for optimal edge strength of the ceramic. IF the design you want uses a metal collar in the ceramic area (say 0.3 mm) then you may place a deep chamfer in the metal area 1.2 mm and a normal chamfer 0.5-07 mm in the metal area.

Thanks a lot 🌹🌹
Hi Dr.Stevenson , can you show us please how you can make a temporary Crown over it after that with luxatemp like example ?.
Okay - coming soon! Thank you
Wish you could post more pfm vids :)
Wil do! Thank you for suggesting.
Hi, Dr. Stevenson.
Would you plz explain how to find the long axis of the anterior teeth(especially #7~#10) when preparing.
I always angle incorrectly.
View from the front of the patient for the mesial-distal angulation, and use the adjacent anterior surfaces for the lingual-facial angulation.
dear doctor i hope you can make video about how to adjust crowns or bridges when having trouble with path of insertion. thank you
You bet!
@@StevensonDentalSolutions that a great topic, please do it Doc
You got it
Wow im super impressed but can you make a video about indirect workin
I will - it's tough with the camera but I will do my best!
Dear Dr,
May I ask about your chair position ? Did you sit at the 7 o‘clock position while doing the procedures ?
Thanks a lot.
7 and 12
Thanks doc! Great demo as always! Could I please ask, regarding the mesial and distal prep. According to ADC exam criteria mesial and distal reduction should be 1.2 to 1.8 mm max for PFM. My reduction coming more than 2 sometimes after removing undercut and proper taper. As I understand I have to measure from the contact area if I am not using diagonal putty. What am I doing wrong with my reduction? How to do it in the criteria? Thank you 🙏🏽
Shoot for 1.0 mm and then refine - you'll always be there.
@@StevensonDentalSolutions thank you for your reply. We only get limited burs. But I’ll try
Great video ! But why does it need to be supra gingiva? Thank you in advance, doctor!
Check out this IG post - we may use different locations for different clinical situations, BUT on dental exams, they want it supragingival in order to easily evaluate the finish line...instagram.com/p/CImluAsJDD5/?igshid=r9mixggikq6a
Doctor how to know the shoulder margin is 90 degree? Thank you Doctor for all informative videos.
Check the angle between the shoulder and the root surface - it should be at least 91 degrees.
@@StevensonDentalSolutions
Thank you so much.
How can I add another like? Every time I watch it, I need to add an extra like 😊
So sweet to say!
sir please upload vedio on post endodontic restoration
It's coming soon
I would like to ask about the position as a right handed operator while making crown preparation on the left molars
I started with 12 position but it was very bad
I think about using 7 position with the patient's head toward the right for the occlusal and buccual preparation
But what position for the rest of the preparation ??
Try 9 for the proximally and lingual with the patient leaning away and the buccal with the patient leaning towards you. Use 12 to double check taper and overall look and make correction from the 9 position.
❤️❤️❤️
Dr Stevenson its also technique of T prep or its another one?
A bit different.
Very nice presentation...sir..
May I know where can I get these instruments..RGS 1 2 3 N 4...can u send any link to..purchase..

@@StevensonDentalSolutions Doctors can help me i have many questions
Thank you so so much for this! We’re supposed to be doing mandibular canine preparations right now and what I find most difficult is holding the handpiece and positioning myself in a way that doesn’t hurt my wrist but also gives me adequate access and control, do you have any recommendations?
Adjust your chair position to allow easier and natural hand and wrist posture. Try 7 o'clock.
You are amazing.did you know that?😍
Oh, I try my best!
Dr.stevenson , we want a general video of tips and tricks for crown preparation that allow function and durability . Such as subragingival or subgingival ? How to avoid injury to the gingiva during prep and during the function after cementation ? , ............ All these small important things that affect the prognosis
Okay - this is a great idea for my clinical series which starts very soon...
@@StevensonDentalSolutions thank you doctor , i am waiting for every new video 😍❤️
@@1smail.khaled Great - I'm working on them!
what camera. do you use?
Canon VIXIA HF G40 with 58 mm Vivitar SERIES 1 Close-up Lens +3.
for the chamfer margin what is that bur?
8877-010
Isnt that a sloppy margin?sir...for a pfmlike with root surface it is more than 90
Shoulders on PFMs should be more than 90 - usually - at least 91 degrees and up to 110, otherwise, the risk of a lip is high. If you look at the root, when the tissue is retracted it would be more obvious that it is close to optimal.
whats the bur at 13:57?
