Extraction of a mandibular incisor

Here are a few examples of mandibular incisor extraction.
This is not a very common treatment option, but when the case is well selected, it gives very good results.
The 1st case was treated in 2001, over 20 years ago. It presented ideal conditions for the extraction of an incisor. The 2nd case is more recent and dates from 2018-19. This patient had undergone orthognathic surgery without orthodontic treatment. She came to see me because she couldn’t close on her back teeth. I therefore extracted an incisor and carried out orthodontic treatment.
The following slide is a summary of an article that will be published in January 2022.
It’s important to remember that case selection is crucial.
The next slide shows a case where a permanent incisor is congenitally missing. The result is satisfactory, but there is a slightly increased overjet.
Finally, I’d like to end with an article by an Icelandic orthodontist. Dr Proffit introduced me to this orthodontist at an AAO meeting.
I applied the principle of preparing the extraction site. I presented the case of a supernumerary lower lateral incisor and a case of congenital absence of 2 lower central incisors where I planned bimaxillary orthognathic surgery.
