Basic Orthodontic Space Analysis Demo

Describes a basic and simple procedure to analyze space in a given dental arch from an orthodontic cast. Please forgive the shaking of the camera as I was doing the demo and photography alone.
You will need a study cast, a digital or vernier caliper, a space analysis form to record your measurements, and a calculator (if you are lazy).

Fayha Adnan I will try my best. I’m unfortunately, my teaching commitments make it difficult to attend my UA-cam channnel well

[@mohammedghamri4030]

can you give us an idea how to do the space analysis in mixed dentition cases ?

[@Dr_Athbi]

I will try to make a video about that in the future

[@Dr_Athbi]

There are a number of statistical and radiographic methods. The one I use most is the simplified Tanaka and Johnston method.

[@amanininii5970]

can you please explain the Bolton method too?

[@lindakosy]

Thank you so much for the tutorial.... it was very informative and helpful

[@ayaeisayed1624]

what's the name of the caliper you are using in the vedio

[@Dr_Athbi]

This is just a simple "Vernier Caliper". I usually prefer digital calipers since I can work faster with them. So I recommend digital. I only used this because I want teach my students how to use it.

Asma Hafizi we typically conduct space analysis from mesial of 6 to mesial of other 6. And hence, we typically don’t include the 6s in required space. This is because the available space we measured is where 5-5 should be. You can include the 6s in required space, but then u have to modify the analysis by measuring your available space from distal of 6 to distal of other 6.
