Minimally invasive repair after root canal therapy: high inlay

Teeth after root canal treatment choice repair method is to consider both functional and beautiful, periodontal health, life, etc. At the same time also to consider as far as possible to retain more healthy teeth body tissue, today the bonding technology is very mature. Minimally invasive repair method - inlay, high inlay, we should be sure, but also dare to try.

Any kind of repair method is not perfect, do not enlarge its shortcomings, but to see more of its advantages, strict control of indications can achieve the desired results.Can be seen from several aspects of the inlay, high inlay:

1.Tooth preparation: inlay, inlay tooth preparation is relatively simple, to avoid the inverted concave

2.Impression：Because the edge is easy to take out the model, so effect is more clear and accurate.

3.Fitness: the model is precise, the repair experience is more closely fit

4.Edge: it can be very good to check the edge of the tight fit, after the cementation highly polished edges

5.Periodontal: gingival margin, reduce the risk of invasion of biological width, can predict a good long-term effect.

6.Minimally invasive: to maximize the retention of healthy dental tissue, reflecting the concept of minimally invasive

After root canal treatment high inlay clinical operation flow:

On the inlay, inlay repair proposed several issues to discuss:

1, How to choose a reasonable choice of materials

2, Whether to use the fiber pile, such as how to choose the root canal of fiber pile

3, The need to cover the occlusal surface or not

4, Whether the need for intramedullary fixation

 

Inlay, high inlay truly embodies the principle of minimally invasive!
