Forced eruption technique: rationale and clinical report.

This article describes a refined, simplified forced eruption technique, and compared it with previous methods. This simplified method is easy to perform and encourages the use of adjunctive orthodontics in general practice. This relatively uncomplicated, quick, and cost-effective treatment can benefit patients.

Severe crowding and a dilacerated maxillary central incisor in an adolescent.

This study reports the treatment of an adolescent patient with dilacerated maxillary incisor. She complained of severe crowding with a high-positioned left upper canine. Her left central incisor had been impacted and moved to proper position at the age of eight years, resulting in a severe root dilaceration. To avoid any progression of root dilacerations and resorption in the maxillary incisor, maxillary lateral expansion and molar distalization plus multibracket appliance were selected as the best nonextraction treatment plan. The maxillary expansion and molar distalization should provide adequate space for the correction of the severe crowding, and treatment with a multibracket appliance was initiated. After a 17-month treatment with a multibracket appliance, an acceptable occlusion was achieved with a Class I molar relationship. An acceptable occlusion was maintained without recurrence of the crowding and impairment of the dilacerated root in the maxillary incisor during three years of retention. It is emphasized that careful planning is required to avoid any progression of the root dilaceration and resorption through orthodontic treatment. A shortening of the period of applying orthodontic force on the dilacerated incisor and avoidance of tooth extraction will minimize the risk factors.

Orthodontic extrusion and orthodontic extraction in preprosthetic treatment using implant therapy.

It has been well documented that orthodontic extrusion is a valuable adjunct to site preparation prior to implant placement. This treatment modality may also be utilized to salvage and restore an extensively damaged tooth for use as a natural abutment. By controlling the orthodontic phase, the hard and soft tissues can be manipulated into a position that permits aesthetic restoration. This article demonstrates the use of this procedure as an adjunct to site preparation and in conjunction with conventional restorative therapy.

[The use of orthodontic goniometry to study apical expansion, using Pr. Planas' method: neuro-occlusal rehabilitation].

In this work, the method of orthodontic goniometry is used, which is a simple technique and not expensive, that allows us to determine the apical expansion in the studied models. 42 patients are studied by means of the techniques of Neuro-Occlusal Rehabilitation. We reach by this method expansion to the level of the apex as far as 12 mm in the lower arch and 11 mm in the upper arch. A simple statistic analysis is made which shows an average of expansions of 7.76 mm at crown level of the upper arch and 8.11 mm at apex level; at the crown level of lower arch we get 6.43 mm and apex level 5.8 mm. We think these results are interesting and they should make us study in depth the Neuro-Occlusal Rehabilitation and its principles.

The use of an existing cast post and core as an anchor for extrusive movement.

PURPOSE: This article describes an original solution for a tooth with an existing cast post and core placed subgingivally. MATERIALS AND METHODS: The tooth was erupted rapidly using a simplified and easy technique that incorporates fiberotomy during the process of movement. RESULTS: The distal finish line of the core, which was subgingival before movement onset, was elevated, allowing the placement of crown margins on sound tooth structure. Clinical evaluation of the tooth after a period of 4 weeks, during which a provisional acrylic resin crown was used for retention, showed no need for corrective surgery, and fabrication of a metal-ceramic crown (Captek) was begun. CONCLUSION: When failing to place crown margins on sound tooth structure, the existence of a cast post and core in such a nonrestorable tooth may serve as an anchor in the process of rapid extrusion. Following the need to respect the biologic width and fulfill the obligatory ferrule effect circumferentially, this extrusive treatment modality was applied to meet high treatment standards.

Prosthodontic management of vertical root extrusion.

The treatment of teeth with subalveolar injury or pathology by vertical orthodontic extrusion technique and fixed prosthodontic restoration has been examined. A prosthodontic technique using a permanently positioned post and core for orthodontic anchorage has been described. This single-dowel technique precludes hazardous repetitive intracanal instrumentation and facilitates esthetic management throughout treatment. Further clinical research is necessary to explore directional force vectors and the treatment of difficult extrusion cases due to occlusal interferences.

Unerupted incisors: a case report illustrating an attractive solution.

A case is described in which, after removal of midline supernumerary teeth on two separate occasions, an unerupted central incisor was brought into the arch with the aid of neodymium-iron-boron magnets. Once the incisor was visible, a pre-adjusted upper edgewise appliance was used to guide the tooth into its correct position.

[Orthodontic treatment of children with cleft lip and cleft palate].

Orthodontic treatment of children with cleft palates continues through the periods of the three dentitions: temporary, mixed, and adult. Using examples, this paper deals with the different difficulties that can be encountered during treatment of this malformation. Orthodontic interception at the time of the temporary dentition corrects the heart of the problem, the transverse insufficiency, but also addresses moderate maxillary retrusion. Cooperation with a speech therapist at this stage is essential. In the mixed dentition, orthodontists correct incisal malalignment and, depending upon the severity of the deformity, consider surgical intervention. In the adult dentition, a variety of decisions must be made: whether to open or close the spaces left by absent lateral incisors; whether to accept an orthodontic compromise or to elect surgical advancement of the maxilla; and, if surgery is deemed appropriate, whether to embark on an early distraction procedure or to rely on a classical osteotomy.

Use of orthodontic treatment as an aid to third molar extraction: a method for prevention of mandibular nerve injury and improved periodontal status.

BACKGROUND: Impaction of mandibular third molars predisposes to pathological conditions including periodontal disease. Extraction of these teeth also may lead to damage to the nerve and to periodontal involvement of the second molars. This report describes a series of cases in which the third molars were orthodontically induced to erupt to prevent the sequelae associated with extraction. METHODS: Impacted mandibular third molars in 18 patients were surgically exposed following placement of an orthodontic appliance. Depending on the individual case, 1 of 3 approaches was used: attachment of a bracket, placement of a post in the root canal, or placement of an orthodontic wire through a bucco-lingual canal. After suturing the mucoperiosteal flap, the orthodontic appliance was activated. After the tooth erupted, it was removed and periodontal parameters were measured on the second molar. RESULTS: No damage to the inferior alveolar nerve was found. Probing depths on the second molar were reduced from 7.9 +/- 1.6 mm on the buccal and 7.4 +/- 1.0 mm on the lingual to 1.8 +/- 0.7 mm and 1.9 +/- 0. 7 mm, respectively. There was an average gain of 5.0 mm in attachment. Keratinized tissue increased from 2.9 +/- 0.7 to 3.8 +/- 0.6 mm. CONCLUSIONS: The interdisiplinary use of periodontics and orthodontics results in non-surgical removal of impacted mandibular third molars without damage to the inferior alveolar nerve and iatrogenic periodontal sequelae to the second molars.
