Management of intrusion depends on several factors such as whether the tooth has a closed or open apex, type of teeth (primary or permanent dentition) and how much the tooth is intruded in mm. This type of dental trauma is complex and is commonly associated with pulpal necrosis and inflammatory ankylosis.
Adult front teeth (which usually erupt at around six years of age) can be replaced immediately if clean. If a tooth is avulsed, make sure it is a permanent tooth (primary teeth should not be replanted, and instead the injury site should be cleaned to allow the adult tooth to begin to erupt). Reassure the patient and keep them calm.
If apex of tooth is displaced towards the palate and making contact with the tooth germ then tooth is extracted Intrusive Luxation: Displacement of tooth into the alveolar bone (pushed into the socket) causing fracture of the alveolar bone. It is the most damaging injury to the tooth and supporting tissues as ankylosis and pulp necrosis can occur.
Dental trauma is a major global health issue and it affects 17.5% of children and adolescents. [9] It is most commonly seen in school children. Dental subluxation is one of the most common traumatic injuries in primary dentition. Maxillary central incisors are the most commonly affected teeth.

Tooth mobility is the horizontal or vertical displacement of a tooth beyond its normal physiological boundaries [1] around the gingival (gum) area, i.e. the medical term for a loose tooth. Tooth loss implies in loss of several orofacial structures, such as bone tissues, nerves, receptors and muscles and consequently, most orofacial functions ...
[1] [2] Typically, a tooth is held in place by the periodontal ligament, which becomes torn when the tooth is knocked out. [3] Avulsions of primary teeth are more common in young children as they learn to move independently (walk and run) and also from child abuse. Avulsed deciduous (primary) teeth should not be replanted.
A certain intrusive force acting on the incisors is counter-acted by an opposite and equal extrusive force acting at the posterior teeth of the same arch. The extrusive force is felt at buccal of the center of resistance of a molar tooth because the bracket slot in the molar tube or band lies buccal to the tooth.
