How to take a dental impression


I am going to start today's post with an apology.I am sorry that my posts were not updated for a long time.I was a bit busy,and it is a bit difficult to run two professional blogs,the dentristry and to study for a post-graduate programme.
But I am back.

Today's post is about taking a dental impression,and making a good impression while doing it!

The process of taking a dental impression is a procedure,that many dentists believe it doesn;t need many explanations.Picture the following conversation

Dr. : "And then we are going to take a dental impression"
Patient : .....
Dr : "And afterards we are going to send it to the lab and .."

As you can understand the patient has no idea what the doctor is talking about. Tis is a common mistake made by dentists. It is not your fault that you don't know;it is the doctor's fault for not explaining.

Back to our post then.

A dental impression is the procedure in which a negative copy of your mouth is made(it is like a copy but imagine looking at it from a mirror) like the one shown in the picture below.

             

This impresion is going to be used to cast an exact copy of your mouth so as to use it for diagnosing and planning your treatment.

The impression depicted above,was used as a final dental impression for a fixed dental prosthesis,that is why it has two materials of different color.It was taken with a silicone-based material for extra detailed depiction of the teeth.
 In case we only want a study model we use a cheaper material such as alginate.

                                        

What is the process like ?

We put the material in a dental tray




                         


                         



 We put the dental tray inside the patient's mouth and wait for the material to set.


                         


When the material sets it is roughly like so

                   

It may have abother color;that depends on the material's brand

With this impression we cast the patient's teeth using dental die stone (aka gypsum)
Thus we have the following image


                    

which is an exact duplicate of the patients' mouth for us to study.

Thank you for reading.And dont forget to smile!
