Have you ever struggled with shades during putting single anterior crown? Were you satisfied with the final outcome? If yes then this video is for you.
You must do the composite restoration. The things which I had told you to record while doing composite restoration of shade matching, those things you have to see and record in ceramic restoration too.
Suppose you are doing a composite restoration in which you only know about shade A2, and you don’t have any idea about surface texture, value and tooth characterization. Can you do invisible composite filling? Maybe your answer will be “NO”. Those friends who don’t know about these watch my previous video because we run a dental lab too. So, I can tell you that there is not much difference between making ceramic restoration and doing composite restoration. Only difference is of consistency or instruments.
So, you have to tell these all things to your technician. So let’s see the check list as soon as possible so that technician could know what is the things he has to do.
FIRST
There has to be perfect balance between three people for invisible ceramic restoration.
Patient
Dentist
Technician
There should be rapport and understanding between you and your technician. Like-
Types of restorations and their indications.
Preparation requirement for particular type of restoration.
Esthetic and function possibilities and limitations.
Cementation and bonding technique.
Now, let’s revise some of the things of prints which convey your lab.
Which type of tooth surface you want- coarse, shiny or dull because tooth surface can totally change the look of the cap.
Second
Select value.
You want high, mid or low value.
The layering of ceramic should be done with enamel or not.
Third
Have you selected hue/chroma?
Which shade is there on cervical area?
Which is there on the body and which cervical is there?
Fourth
Determine translucency or transparency.
So it’s better you divide the tooth in 9 parts and draw the feature of extent in each part.
Fifth
If you are going to make mental free cap then have you taken stump shade.
Important for material like E max.
If the stump shade is dark then how are you going to do masking.
Sixth
Decay any tooth characterization.
Like- any crack line, enamel white, florosis stain.
You can mask these things by comparing it to the nearby tooth.
Seventh
Draw the design of dentin lobe with pre operation photographs or nearby tooth.
How to see this dentin lobe is told to you in my previous video.
Second last
Look for extrinsic stains like in tobacco chewing.
Last
You have to judge your gingival level so that you can tell the people of lab that gingival ceramic should be added or not.
These all things were about single tooth, but there are more things for bridge.
This is the prescription chart of our lab shown to you-
There is a diagram in this. You have to write shade progression, if you will not tell this then technician will make all the crowns of the same shade.
And you know that the central incisor is the brightest and there is more chroma and less value in canine.
So, you have to make proper shade progression.
After that it may happen that you are applying multiple crowns for smile designing.
Then you can make the designs of incisal edge in this way only.
If you want to make your work more perfect then you can select pontic designs also.
And this is also good that you tell your lab about margins that the design of your preparation is supra-gingival or sub-gingival.
At last send the photographs to your lab so that he understood everything.
So, we can send study models, impression, photographs, wax up, shade guide, bite registration. Prescription with diagram, provisional restoration model to our lab to have the best result.
THANK YOU…….
