Traitement orthodontique accéléré par corticotomies : quelles sont les alternatives minimalement invasives ?

Introduction: The duration of orthodontic
treatment in adults remains a barrier for some patients. Some surgical techniques
have been developed in order to accelerate orthodontic tooth movement. The
technique of corticotomies is effective in decreasing the orthodontic treatment
time but remains invasive, leading to significant postoperative consequences.
Materials and Methods: Minimally invasive techniques without muco-periosteal
flap elevation have been developed: corticision, micro-osteoperforations,
piezopuncture and piezocision. Results: The piezocision procedure seems to be
the best compromise to accelerate orthodontic tooth movement while respecting
a specific surgical and orthodontic protocol. The piezocision surgery allows the
addition of biomaterials in cases of dehiscence and/or fenestration on the alveolar
bone associated with moderate to severe overcrowding. Conclusion: According
to current publications, minimally invasive corticotomy techniques can be viewed
as a new therapeutic tool in the acceleration of orthodontic tooth movement.
