The replacement or repair of teeth with artificial substitutes that are fixed in place in the mouth is the focus of the dental prosthesis branch known as the fixed prosthesis. The fixed prosthesis can be securely cemented onto dental implants, dental roots, or natural teeth. In this video, Dr. Richard Stevenson demonstrates about Fixed Dental Prosthesis Preparation ( FDP) - #3-#5 WREB-ADEX-CDCA performed on the Acadental ModuPRO Prosth typodont.

The skill of Dr. Stevenson should not be underestimated. His YT vids are amazing, but don't despair if you don't reach his level. This clinician has a level of clinical skill that far exceeds most and it is amazing to watch and have aspirations to achieve. With practice you should be able to follow his habits and achieve a passing score on licensure. Thank you Dr. Stevenson

thank you for the amazing video! It was super helpful. I Just want to make sure I am not missing something- I know ADEX requirements are always changing. Currently, the 2024 manual says that an occlusal reduction of 1-2mm for a cast metal crown adheres to the criteria. So 1mm would be sufficient occlusal reduction for a cast metal crown for the purpose of the exam- correct?

It's approximately 110 degrees from the A plane, assuming a 35 degree cusp incline angle, but the easier tip is to angle it so that the cusp tips on the lingual line up with the adjacent teeth.

Hello Dr Thanks for amazing videos Can i ask u question What is the difference between shoulder and chamfer preparation and when use them ? What type of burs used in preparation PFM Taper with round or flat ?

@StevensonDentalSolutions 4 жыл бұрын

Shoulder approaches 90 degrees to the unprepared tooth surface and allows for ceramic materials to be close to 90 degrees and of adequate bulk for strength. Chamfer is a steeper declination angle forming a obtuse angle with the unprepared tooth surface and are used with metal materials to form a slip joint. PFM can use either a round ended or flat ended, as long as the finish line angle approaches 90 degrees and the axial depth at the margin is 1-1-2 mm.

Wings are just more conservative, less tooth structure is removed interproximally. The walls of the wings might enhance resistance firm as well.

Do you recommend leaving the wings on the #5-PFM abutment? I saw a previous PFM prep video of yours where you blended away the wings at the end so it was a smooth transition. What is the benefit to keeping the wings versus smoothing them away? Is either way (wings vs smoothing away the wings) an acceptable method for the board exam? Thank you for your video, very helpful!

@StevensonDentalSolutions 4 жыл бұрын

Both are acceptable. Leaving them creates a potential draw challenge, as the vertical walls created adds an additional set of vectors to consider. Smoothing them away if slightly more aggressive to the tooth, but not by much.

How do recommend the transition from shoulder to chamfer on #5? I've decided to smooth the wings away because of potential draw issues. I appreciate your help. Thank you.

@StevensonDentalSolutions Жыл бұрын

Good choice - the shoulder must be present in the esthetic area, namely the facial side of the mesial interproximal contact and the distofacial tooth line angle. From these two points lingually, the shoulder-chamfer transition occurs.

@danielp3692 Жыл бұрын

In reference to the transition, do I just go with the chamfer very very gently into the shoulder? What does the actual "meeting" point of the transition look like? Thank you.

Hello dear Dr.Stevenson, could you please make an amalgam restoration guide for class 2 cavity MO... Cause I've made 3 restorations for that cavity during past 2 days and it all fails due to a fracture in the proximal area and exactly distolingual part, I'm not sure why it keeps breaking there although I've made enough condensation and I was trying to be as gentle as possible during carving and pre/post burnishing and by the way I'm still a student. Please help me with that, I would really really appreciate it. *All the love for the great work you're doing to help people in your channel

I'm looking over the WREB PFM prep grading criteria and all they say is that the PFM margin needs to be 1-1.5mm. From what I understand, that will work for the buccal margin but isn't the lingual chamfer margin usually 0.5mm? It was a little confusing to me and was afraid a 0.5mm lingual margin would be considered too shallow according to their grading criteria. Because of this, I know many students choosing to just do FCC for both posterior abutments since the WREB allows you to choose, to play it safe. Do you have any thoughts on this? Also, I see the burs you're using and I'm used to using an 856-012 or 856-014 for both chamfer margins and a shoulder margin (I just make a deeper chamfer if I'm doing a shoulder margin). Is this the wrong way to go about this?

@StevensonDentalSolutions 4 жыл бұрын

Correct - the WREB criteria has changed - they want a deeper chamfer on the lingual. Use the 846-014 for the majority of the prep, and like you said, proceed deeper axially on the facial for a shoulder. And...yes, the FGC, Zirconia crowns are easier for sure.

Hi Dr. Stevenson, is it ok to do axial reduction before occlusal reduction? For some reason my occlusal anatomy is not good if I start with occlusal reduction first, however I do know I need a lot more practice. Just wanted your opinion on that. Also Is there a way you could show the position of the handpiece through a video when using indirect vision for occlusal reduction for the bridge #3-#5. Thank you.

@StevensonDentalSolutions 4 жыл бұрын

1. Yes, absolutely - the only challenge with this technique is breaking proximal contact (because it's so tall) - but if it's easier, keep on using this technique! 2). The video of this is difficult - I do this live for my students, but I will in the future... Thank you!

Hi Dr.Stevenson, In this particular video, you have created secondary planes on both the facial and the lingual walls while in the other videos secondary planes are created on the lingual wall of upper molar/premolars and facial walls of lower molar/premolar and not both the walls. Can you please explain the reason?

@omargad7494 3 жыл бұрын

I was asking this, and I got an answer: secondary planes are made on lingual of upper and facial of lower. That's the basic. But if you notice the original contours of the facial of the upper, you will notice that they are on 2 planes. So it's better to make them on 2 planes too. (So, all the facial and lingual of posteriors are on 2 planes except the lingual of lower). Hope that was helpful.

Hello doctor RGS. I have a question. Is it really good idea to put bridge on premolar and molar? I was taught in school that molars and canines are 1st class pillars and premolars are 2nd class pillars. And that two premolars together create 1st class pillar. And a bridge should always be on 1st class pillars on both ends. Shouldnt the bridge be extended to the canine then?

@StevensonDentalSolutions 4 жыл бұрын

No bridge is better than an implant. There are no clinical studies to validate your dental schooling regarding fixed dental prostheses - only theories. Thank you for your question.
