so when I look at this picture, a full crown preparation on the case of a non-vital tooth,
3
I'm always sad because I did that and I did it a long time ago,
4
but I tell you I wouldn't do that anymore today and I'm prepping less and less crowns.
5
I want to say even I am not prepping crowns anymore.
6
I am replacing crowns when they exist already.
7
Otherwise, I always try to use a biomimetic approach, using adhesion, using a selective preparation of the tooth, not a full preparation.
8
And these mistakes I did in the past, I show you another example.
9
I want to humble myself on that.
10
I want to say this was wrong.
11
maybe right at the time
12
but this is wrong today we don't want to kill the pulp in the name of prostodontics
13
because when we do that then we need to use post
14
and core buildups and and different things that are very difficult to restore
15
and I want to show you that today we don't need
16
that anymore we need just to replace what is required
17
and no more and many times the palatal
18
or the lingual surface of the tooth is intact
19
and doesn't need any preparation
20
so I want to show you now a little tour a
21
little tour on the indications of the the spectrum of indications then we'll talk about tooth preparation
22
and and provisionals and we'll finish with some aspects of bonding procedures.
23
And please believe me, one hour and a half is nothing to present what I want to tell you.
24
However, I tried to make a really concentrate for you of what I think is important.
25
And in the indication, I just want to remind you, there are different types of bonded porcelain restorations the anterior dentition
26
and I call them type 1 type 2
27
and type 3 according to the amount of tooth substance that we are replacing according to the amount of interdental preparation
28
and as you know the type 1 restoration the typical type 1 was described in the early 80s by Horn Calamia,
29
Simonson, and it was really about minimal approach,
30
minimum preparation or no preparation, reduced incisal coverage.
31
And this is really the typical type 1, what I call type 1.
32
And all these papers taught us that, including my friend Mark Friedman, who published a 15 year follow-up review,
33
they taught us that as long as you prep in enamel, you are fine.
34
If you exposed a significant amount of dentin, you are in trouble.
35
That was true back then, it isn't true anymore today
36
and I will explain why in the 90s we have an extension of the indication towards more tooth substance replacement,
37
type 2 and type 3 restoration.
38
This is more the daily bread of bonded porcelain restoration because the early indications,
39
the type 1, today we solve them mostly by bleaching.
40
Now, about these possibilities, we have,
41
as I said, bleaching will address most of type 1 indications however still we have some indications
42
that will not be covered by bleaching like severe discoloration non-response to
43
and internal bleaching for instance we have type 2 are going
44
to be more tooth substance replacement conoid teeth diastema triangle incisal prominence to be restored incisal guidance to be restored.
45
Type 3 will be about extensive loss of tooth substance, coronal fracture, and extensive loss of enamel by erosion and wear.
46
So a very classical example of type 1 for me is the case of endodontically treated teeth,
47
like these two central and lateral incisors in this case.
48
And a lot of people believe that veneering endodontically treated teeth is not a good idea.
49
And Iowann really opposed to that.
50
It is an excellent idea.
51
If bleaching is not successful, if there is an indication for restructuring the shape, the length of the tooth,
52
then veneers or bonded porcelain restoration are the perfect choice.
53
We have to know that endodontically treated teeth are more brittle not because of the loss of the pulp per se,
54
but because of the loss of tooth structure.
55
The tooth structure loss becomes the primary cause of failure, not the pulp removal.
56
In this context, the more conservative approach of veneer will maintain more remaining tooth substance,
57
especially in a situation like this one, a 360 shoulder preparation would result in a total loss of the coronal substance.
58
And the next thing you would have to think about is which type of post and core I want to use.
59
And of course, this is a question we don't like too much and we want to avoid.
60
And we know from many scientific publications that the best post is no post.
61
And therefore, if we choose to use a porcelain veneer type approach in these teeth, we know that we are going to get the same reinforcement that we need.
62
We are going to recover the stiffness, especially because the ceramic, as a stiff material,
63
will act like a surface post or call it a skin post.
64
I don't know how to say that.
65
but it will apply the stiffness where it should be recovered, not at the level of the pulp, but at the level of the enamel layer.
66
And so if we apply the porcelain veneers the right way by increasing the volume of enamel, then we can restore the original stiffness of the tooth,
67
even on an endodontically treated tooth.
68
And that's what we did in this case on the central, the lateral incisor.
69
We included the contralateral central because it had a defect
70
and we wanted also to improve the cohesiveness of the smile line
71
and including the two centrales allowed us to develop a very nice curvature of the incisal edge lines,
72
cohesive with the lower lip line.
73
You see on the right the teeth after preparation.
74
You see how conservative is the preparation.
75
And the veneer is going to really like it as a surface post to give these teeth back what they have lost,
76
which means stiffness and rigidity.
77
And plus we have increased, we have improved function by guidance, by anterior guidance.
78
And I will tell you about that again.
79
Anterior guidance is your friend.
80
If you know how to bond the restoration, interior guidance is your friend.

Context & Background

In this segment, Pascal Magne discusses advancements in dental restoration techniques, particularly focusing on the evolution of crown preparation practices. He reflects on his past approaches and emphasizes the shift towards a biomimetic methodology which prioritizes minimal intervention and a focus on preservation of natural tooth structure. This perspective not only showcases the importance of adapting one's practices but also serves as an analogy for English learners to embrace flexibility and evolution in their language learning journey.

Step-by-step Shadowing Guide

To effectively improve your English speaking skills using the shadowing technique, especially with complex topics like dental restoration methods, follow these steps:

  1. Choose a segment: Select a specific part of the video that resonates with you, such as Pascal Magne’s explanation of type 1 restorations.
  2. Listen carefully: Play the chosen segment and pay attention to the pronunciation and rhythm of the speech. Note how Pascal structures his sentences and conveys meaning.
  3. Repeat phrases: As you listen, start repeating the phrases immediately after he says them. Use a shadowing app to help match your speech to his tone and pace, which is essential for improving fluency.
  4. Focus on emotion and meaning: While shadow speaking, try to capture the emotion and context behind the words. This will enhance your overall speaking ability and comprehension.
  5. Record yourself: After practicing, record your own rendition of the excerpts. This feedback loop will help you identify areas for improvement.

Using these methods empowers you to absorb the language actively while enhancing your vocabulary and articulation. The shadowing technique is particularly effective as it immerses you in natural speech patterns, ultimately leading to greater confidence in your English speaking practice.

Qu'est-ce que la technique du Shadowing ?

Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
