Surgical exposure and orthodontic extrusion of an impacted canine tooth in a cat: a case report.

A 7 month-old, male domestic shorthaired cat was referred because of facial swelling, an operculated cystic oral mass, and impaction of the associated maxillary left canine tooth. Surgical exposure and realignment failed to result in eruption. Surgical reexposure and orthodontic extrusion resulted in a functional alignment of the tooth within the dental arch. Follow up evaluations over the 5 ensuing years indicated persistence of the facial deformation, no evidence of ameloblastic biotransformation, and a healthy tooth.

The role of orthodontic extrusive remodeling in the enhancement of soft and hard tissue profiles prior to implant placement: a systematic approach to the management of extraction site defects.

A classification scheme that systematizes the wide range of regenerative potential of common extraction site topographies is presented. Within this system, the parameters for immediate implant placement and preliminary ridge augmentation are discussed. In addition, a new adjunctive role for orthodontic extrusion is introduced. This approach is intended to manipulate "hopeless" teeth to modify their local defect environments, thereby enhancing the predictability of subsequent implant placement at those sites.

Controlled orthodontic extrusion to create gingival papilla: a case report.

Prosthetic dental restorations alone do not produce esthetics. They must be in harmony with the surrounding gingiva, especially the gingival papilla. This case report describes the enhancement of the gingival papilla between an implant replacing the maxillary left central incisor and a provisional crown on the maxillary left lateral incisor. Esthetic harmony was disrupted by the absence of an interproximal papilla. First, provisional crowns on the implant and adjacent tooth were used in an attempt to remodel the interproximal gingival tissue, but the esthetic result was not satisfactory. The second attempt involved orthodontic extrusion of the lateral incisor in an incisal direction. The gingival tissue migrated incisally, thus restoring the deficient papilla and establishing restorative and gingival harmony. Both the implant and the lateral incisor were restored with ceramic crowns.

Orthodontic extrusion of an extensively broken down anterior tooth: a clinical report.

A predictable esthetic restoration is not limited to the restored teeth; it has to include the gingival unit and its interface with the teeth involved. Failure to deliver restorations that maintain gingival health jeopardizes the success of any restorative procedure and creates potential for periodontal problems. Perforations, fractures, root resorption, or caries in the cervical area of the tooth, especially in the anterior part of the mouth, present many challenges to the clinician. Failure to place the crown margins on sound tooth material may violate the biologic width and should be considered a restorative failure. Orthodontic root extrusion or forced eruption is a well-documented clinical method for altering the relation between a nonrestorable tooth and its attachment apparatus, elevating sound tooth material from within the alveolar socket. It has some advantages over surgical crown lengthening, which is less conservative considering the sacrifice of supporting bone and the negative change in the length of the clinical crowns of both the tooth and its neighbors. This article presents a case of a maxillary right lateral incisor, extensively broken down following trauma, treated with orthodontic extrusion combined with gingival fiberotomy, without a need for a corrective surgical procedure.

[Crown lengthening by orthodontic extrusion. Principles and technics].

Forced Eruption by orthodontic means is an effective way of managing subgingival caries and root fractures at the level of the osseous crest or below. It allows the dentist to construct restorations on otherwise hopeless teeth and maintains the biologic distance between the apical portion of the junctional epithelium and the alveolar crest.

Adhesive fragment reattachment after orthodontic extrusion: a case report.

In the treatment of crown fractures, adhesive fragment reattachment provides a good alternative to other restorative techniques, offering several advantages. The present paper reports a case in which the treatment of a cervical crown fracture was accomplished by reattaching the tooth fragment with a flowable resin composite. Orthodontic root extrusion was performed with a modified Hawley appliance prior to fragment reattachment. The clinical and radiographic results after 2.5 years were successful.

Orthodontic extrusion of subgingivally fractured incisor before restoration. A case report: 3-years follow-up.

Orthodontic forced eruption may be a suitable approach without risking the esthetic appearance in tooth fracture below the gingival attachment or alveolar bone crest. Extrusion of such teeth allows elevating the fracture line above the epithelial attachment and so the proper finishing margins can be prepared. Restoration after orthodontic eruption may present a more conservative treatment choice in young patients compared with the prosthetic restoration after extraction. This case describes a multidisciplinary approach using the orthodontic forced eruption facilitating the composite restoration of a fractured upper permanent central incisor.

Orthodontic extrusion of premolar teeth: an improved technique.

Traditional methods of tooth restoration may be impossible because of insufficient crown length. This article describes a method to orthodontically extrude "nonrestorable" premolar teeth. More than 100 patients who required premolar extrusion before prosthetic restoration have been treated with this procedure. Clinical records of a typical patient are shown to demonstrate the effects of the application of this technique, and a method of bracket placement on a severely broken down "nonrestorable" tooth is described. The advantages of the technique recommended in this article are described.

Rapid orthodontic extrusion of crown root and cervical root fractured teeth.

This study concerns the relapse tendency and extent of root resorption in 33 extruded non-vital crown root fractured or cervical root fractured teeth in 32 patients 10-20 years old. They constitute all orthodontically extruded teeth at the Orthodontic or Pedodontic Departments, Eastman Institutet, Stockholm (1982-1987). A simple extrusion mechanism exerted a force of 60-70 p along the root axis of the tooth. An extrusion of 2-3 mm was obtained in most patients; the most extreme effect was 6 mm. In 16 patients the extrusion was achieved within 3 weeks, in 12 it lasted for 4-6 weeks and in 5, 7-9 weeks. The treatment was more complicated in the lower jaw. After the extrusion, a fibrotomy was done and in most patients also a gingival recontouring to create an optimal relation between the gingiva and the margin of the restoration. Periodically identical radiographs were taken immediately before and after the extrusion, after 3 months and after 1 year. A minor relapse, about 0.5 mm, was observed in 3 patients. Limited root resorption was found in 6 teeth and severe in only 1. The resorptions did not progress in the following 2 years of observation.

Raising the root. A look at orthodontic extrusion.

A simple technique using bonded wires to establish anchorage and an attachment to a tooth requires a minimum of special materials or advanced skills in orthodontics. The bonded wire stabilizes the anchor unit and avoids any adverse tooth movement.
