Treatment of an ankylosed central incisor by single tooth dento-osseous osteotomy and a simple distraction device.

When teeth are replanted after being avulsed, the repair process sometimes results in ankylosis. In a growing child, the ankylosed tooth fails to move along with the remaining alveolar process during vertical growth, resulting in a tooth that gradually appears more and more impacted and requires several reconstructive procedures to correct. Ankylosed teeth can, however, serve as anchorage for orthodontic correction of a malocclusion and as a point of force application for a dentoalveolar segment during alveolar distraction osteogenesis. This case report describes the treatment of a 13-year-old girl whose maxillary left central incisor had been avulsed and replanted 5 years earlier. The tooth had become ankylosed, and it was used to provide "free anchorage" during distalization of the maxillary dentition. The underdeveloped alveolar process adjacent to the ankylosed tooth was reconstructed by dento-osseous segment distraction osteogenesis, by using the ankylosed tooth as the point of force application.

Orthodontic finalization strategies in dysfunctional adult patients.

Although orthodontic treatment for the finalization of temporomandibular dysfunction (TMD) patients is often advocated, it represents a risk of failure. Furthermore, in the literature there are few articles that illustrate appropriate orthodontic strategies for the finalization of these patients. In this article the authors suggest a step-by-step clinical procedure in order to: 1. verify the rationale for orthodontic finalization in TMD patients; 2. illustrate the guidelines for correct orthodontic treatment; and 3. suggest a strategy to stabilize the mandible during orthodontic treatment and to retain that stabilization after treatment. If splint therapy is successful in relieving the TMD symptoms, a fixed posterior bilateral stop is used for occlusal stability. After one or two months during which the bilateral stop is shown to be adequate in maintaining TMJ health without a splint, orthodontic finalization can be performed with minimal risk of failure. The essential sequences of Class I, Class II, and Class III treatment for the finalization of TMD patients are also presented. The difficult goal of a long term stability in cases that have been orthodontically finalized is reached by the conversion of the posterior bilateral stops (crown build-ups) into permanent vertical stops.

[Orthodontic treatment of malocclusion with periodontitis].

Adults with untreated malocclusions suffer from more periodontal disease than if their malocclusion had been corrected orthodontically. What orthodontists can offer in the management of patients with periodontal disease, how they can help the periodontists and the patients, and how the periodontists can help the orthodontist make treatment safe and purposefully are widely discussed. The purpose of this study is, therefore, to discuss how orthodontic patients with severe periodontitis could be treated and what we should do for these patients during the treatment as well as at their initial visit. One case is presented as an example of treatment for malocclusion with sever periodontitis: The patient was a 23 years 8 months female with a chief complaint of protrusion of upper incisors. Since clinical examination revealed severe periodontitis, periodontal treatment was undertaken for one year prior to orthodontic treatment. From these observations, we are conviced of the importance again of the global approach and the team treatment method in treating malocclusions with periodontitis.

An American Board of Orthodontics case report. Correction of a Class III mandibular prognathism and asymmetry through orthodontics and orthognathic surgery.

The Class III malocclusion with mandibular prognathism can involve many factors, among which are excessive mandibular growth, underdevelopment of the maxilla, environmental factors, and trauma to the jaws. The correction of this malocclusion can involve an orthodontic or a combined orthodontic-orthognathic approach. Skeletal asymmetries can complicate this situation, making treatment either more difficult, more complicated, or both. This case presentation involves treatment with a combined orthodontic-orthognathic approach. [This case was presented to the American Board of Orthodontics in partial fulfillment of the requirements for the certification process conducted by the Board.]

[Corrective movement of a palatal impacted canine tooth: methodology and outcome of a combined oral surgery/orthodontic procedure].

In 24 patients, 31 palatal impacted maxillary canines were brought in position using the same surgical and orthodontic concept. After temporal surgical exposure a little silver chain was attached at the crown of the canine, the mucoperiostal flap was repositioned, and the canine was moved into its position by innovative orthodontic treatment means. The combined method is described intensively. With respect to the applied technique the results indicate that according to the criteria of periodontal status, vitality, bone support, root resorption and occlusion no differences exist to free erupted canines despite a mean orthodontic correction of 36.7 degrees.

Bridging and dimensions of sella turcica in subjects treated by surgical-orthodontic means or orthodontics only.

The aim of the study was to compare the incidence of sella turcica bridging and sella turcica dimensions in 150 Caucasian subjects who had combined surgical-orthodontic correction of their malocclusion with a randomly selected group of 150 Caucasian subjects who were treated contemporaneously by orthodontic means only. Pretreatment lateral cephalometric radiographs were scanned and analyzed. A sella turcica bridge was identified as a continuous band of bony tissue extending from the anterior cranial fossa to the posterior cranial fossa. The dimensions of the sella turcica were measured. In the group treated by combined surgical-orthodontic means, the incidence of bridging was 16.7%, whereas it was 7.3% in the orthodontics-only group (P = .012). Significant increases in the mean surface area (P = .02) and mean perimeter of the sella turcica (P = .01) were found for the combined surgical-orthodontic group compared with the orthodontics-only group. The mean interclinoid distance was significantly smaller in the surgical-orthodontic group (P = .02). These findings appear to indicate the greater likelihood of sella turcica bridging and abnormal sella turcica dimensions in subjects treated by combined surgical-orthodontic means rather than by orthodontics only.
