Reeruption and extrusion of a traumatically intruded immature permanent incisor: case report

Orthodontic Extrusion vs. Surgical Extrusion to Rehabilitate Severely Damaged Teeth: A Literature Review

The need to rehabilitate severely compromised teeth is frequent in daily clinical practice. Tooth extraction and replacement with dental implant represents a common treatment choice. However, the survival rate for implants is inferior to teeth, even if severely damaged but properly treated. In order to reestablish a physiological supracrestal tissue attachment of damaged teeth and to arrange an efficient ferrule effect, three options can be considered: crown lengthening, orthodontic extrusion and surgical extrusion. Crown lengthening is considered an invasive technique that causes the removal of part of the bony support, while both orthodontic and surgical extrusion can avoid this inconvenience and can be used successfully in the treatment of severely damaged teeth. The aim of the present narrative review is to compare advantages, disadvantages, time of therapy required, contraindications and complications of both techniques.

A Novel Approach to extrude Subgingivally Fractured Tooth using Customized Removable Appliance

Traumatic dental injuries (TDIs) are common in growing children. Among all the dental injuries, complicated crown root fractures (Andreasen Class VI) of maxillary permanent anterior teeth are relatively widespread. Such fractured teeth are often considered as hopeless and are extracted. However, if the tooth is to be retained, various treatment strategies have been proposed. The aim of the present case report is to suggest a new technique to treat a complicated crown root fracture. The management of this case included endodontic procedure and orthodontic extrusion to move the fracture line above the supragingival level. A customized removable Hawley’s appliance with a modified single cantilever spring was fabricated and an anchoring Begg bracket was bonded on the residual crown of the tooth. This method is useful in the mixed dentition when there is insufficient anchorage of adjacent teeth because of preshedding mobility and trauma.

Spontaneous re-eruption of intruded permanent incisors: five case reports

This report presents 5 cases of intrusive luxation in immature permanent central incisors. The intruded incisors, with careful monitoring, were allowed to spontaneously re-erupt, which avoided the need to reposition the tooth either orthodontically or surgically. All of the teeth re-erupted spontaneously in a few months. The root development continued in all of the cases and all pulps remained vital. There were no other signs of pulpal and/or periapical pathology. It can be concluded that intruded immature permanent teeth can spontaneously re-erupt, conserve their vitality, and continue their root development without any surgical or orthodontic management.

Re-eruption of traumatically intruded mature permanent incisor: case report

This case report describes a case of intrusion of the right mature permanent central incisor. After gingivectomy and endodontic treatment with changes of the intracanal dressing (calcium hydroxide paste) every 30 days, spontaneous re-eruption was observed. We conclude that waiting for spontaneous re-eruption associated with gingivectomy and endodontic treatment is an alternative treatment for severe intrusive luxations in mature permanent teeth.

Combined apexification and orthodontic intrusion of a traumatically extruded immature permanent incisor

A patient with a traumatic extrusion of the maxillary right central incisor was referred to the Pedodontic Clinic of Gazi University Faculty of Dentistry after 15 days. Orthodontic repositioning of the tooth was planned in 6 months. At the beginning of orthodontic therapy it was observed that the tooth was necrotic and needed an apexification procedure. The apexification procedure and orthodontic intrusion were successfully performed at the same time. In addition, a "walking bleach" was performed after the orthodontic and endodontic procedures were completed. At the 3-year recall, the tooth appeared normal in all respects.
