USE OF INTRUSION ARCH FOR DEEP BITE CORRECTION: INTRODUCTION

Deep bite is a very common finding in the clinic of orthodontics, and its correction may involve intrusion of maxillary incisors, intrusion of mandibular incisors, extrusion of posterior segment or any combination of those. The proper correction of this type of discrepancy require differential mechanics, and the use of intrusion arch associated to the segment arch technique allows us to apply the most suitable mechanics.
Aim:
The aim of this article is to show the intrusion arch capabilities to correct the deep bite according to the nature of the discrepancy.
Results:
The mechanics to be employed should respect the nature of the discrepancy, which often require an appliance that is able to produce a force system suitable for a specific problem. When an intrusion of anterior teeth is required to correct the deep bite the intrusion arch is a type of appliance that allow us to produce the proper force system, not only in respect to its magnitude, but also the line of action of the force needed to intrude teeth with different axial inclinations.
Conclusions:
The intrusion arch is an appliance that offer the possibility to customize the mechanics for deep bite correction. The possibility of controling the magnitude and direction of the force system enhance the outcomes and reduce the side effects.
