Intrusion Mechanics in Orthodontics

Abstract

Various methods for incisor intrusion and molar intrusion are discussed in detail in this review. These techniques involve applying different forces and mechanics to move teeth vertically into the jawbone.For incisor intrusion, methods such as utility arches, Connecticut intrusion arches, Burstone intrusion arches, K sir Arch, and tip back springs are utilized. Each of these methods employs unique mechanics to achieve the desired vertical movement of the incisors.On the other hand, molar intrusion techniques include the use of Temporary Anchorage Devices (TADs), headgears, biteplanes, magnets, maxillary intrusion splints, Invisalign, and active vertical correctors. These methods provide various approaches to intrude molars by applying force in different ways.The choice of intrusion method depends on factors such as the specific orthodontic case, treatment goals, and patient anatomy. Each technique has its own advantages, limitations, and indications for use in clinical practice..The aim of this overview is to provide information for approaching the ways of intrusion.
