1/15. Treatment of a patient with a Class II malocclusion, impacted canine, and severe malalignment.A case report of the orthodontic treatment of a male adolescent with a unilateral dental Class II malocclusion, an impacted canine, severe maxillary malalignment, and a canted maxillary anterior occlusal plane. Treatment consisted of full fixed appliances, extraction of the maxillary right first premolar, and surgical exposure of the impacted canine. Treatment vastly improved the patient's facial and dental esthetics. A Class I skeletal and dental relationship was established, along with a functional anterior guidance. The dental arches were coordinated and the dental midlines coincident with the midsagittal plane. This case report was presented to the American Board of orthodontics in partial fulfillment of the requirements for the certification process conducted by the Board.- - - - - - - - - - ranking = 1keywords = adolescent (Clic here for more details about this article) |
2/15. Treatment of a Class II Division 2 malocclusion with space reopening for a single-tooth implant.This case report describes the treatment of an adolescent girl with a skeletal Class II Division 2 malocclusion and impinging overbite. One of 2 previously extracted premolars had to be replaced by a single-tooth implant after adequate space reopening. An optimal overbite-overjet relationship was achieved through significant intrusion and proclination of maxillary and mandibular incisors. A horizontally impacted mandibular second molar was repositioned to ensure a 2-molar arch integrity. Resolution of the gingival smile line and favorable facial changes were also obtained.- - - - - - - - - - ranking = 1keywords = adolescent (Clic here for more details about this article) |
3/15. Non-extraction Tip-Edge appliance management of a moderate Angle Class II division 1 malocclusion commenced in the late mixed dentition.This case presentation concerns the correction of a moderate Angle Class II division 1 malocclusion of a patient whose treatment began during the late mixed dentition. Owing to the need to preserve and improve the existing facial aesthetics, treatment was started with a non-extraction approach and, in order to exploit favourable dentofacial growth changes and to avoid the possibility of extraction of teeth, was timed to coincide with the patient's expected adolescent growth spurt. Fixed appliances only were used. Special consideration had to be made for the patient's fractured upper central incisor teeth. An aesthetically pleasing treatment outcome was achieved within the expected time frame for correction. The case shows the successful combination of typical Begg mechanotherapy used during the early stages of treatment and Tip-Edge rectangular archwire mechanotherapy as used for the later and finishing stages.- - - - - - - - - - ranking = 1keywords = adolescent (Clic here for more details about this article) |

5/15. Management of congenitally missing second premolars with orthodontics and single-tooth implants.This article describes the treatment of an adolescent girl who was congenitally missing all 4 second premolars and had a retained mandibular second primary molar. Various treatment alternatives are discussed, and the final treatment plan of space opening for 3 implants and space closure of the maxillary left second premolar site is presented.- - - - - - - - - - ranking = 1keywords = adolescent (Clic here for more details about this article) |
6/15. Planas direct tracks in young patients with Class II malocclusion.In brazil, Class II malocclusions affect approximately one-third of children in the primary dentition period, and approximately two-thirds of the adolescent population. According to many authors, this type of malocclusion worsens with time, due to facial growth during childhood, both in terms of quantity and quality, and the facial pattern is established at an early age. The application of the Planas Direct Tracks concept and technique may represent an interesting tool for the correction and prevention of Class II malocclusion in an early treatment approach, working 24 hours a day, 7 days a week, applying oral functions and muscle activity to correct the malocclusion.- - - - - - - - - - ranking = 1keywords = adolescent (Clic here for more details about this article) |
7/15. 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.- - - - - - - - - - ranking = 5keywords = adolescent (Clic here for more details about this article) |
8/15. Treatment of a unilateral Class II crossbite malocclusion with traumatic loss of a maxillary central incisor and a lateral incisor.This case report describes the multidisciplinary management of an adolescent girl with traumatic loss of the maxillary right central lateral incisors, and a unilateral Class II crossbite malocclusion. A rapid palatal expansion appliance was used initially to correct the transverse deficiency and secondarily as an anchorage unit for unilateral molar distalization to correct the Class II molar relationship. Temporary incisors were extended from a Nance stabilizing appliance during premolar and canine retraction. A staged approach was used with bone grafting before the placement of 2 single-tooth implants. A favorable outcome was achieved through proper coordination among the orthodontist, the surgeon, and the restorative dentist.- - - - - - - - - - ranking = 1keywords = adolescent (Clic here for more details about this article) |
9/15. Periodontal complication during orthodontic therapy. A case report.Occasionally periodontal complications arise during adult orthodontic therapy, although conditions may also occur in adolescent patients. This case report describes the periodontal condition that developed during orthodontic treatment of an adolescent girl. Eleven months after the start of treatment, an unusual hyperplastic soft-tissue lesion developed that did not respond to conservative treatment. The case history, orthodontic treatment, periodontal treatment, histopathology, and follow-up are described. Suggestions for prevention and early diagnosis of similar problems are reviewed since particular periodontal infections may progress subclinically.- - - - - - - - - - ranking = 2keywords = adolescent (Clic here for more details about this article) |
10/15. Treatment of Class II deep bite by orthodontic and surgical means.Conventional orthodontic correction of the Class II deep-bite deformity with a decreased lower anterior facial height tendency can be mechanically difficult, inefficient and, in many instances, impossible. Orthodontic treatment alone of either adults or adolescents with such deformities frequently can neither increase lower anterior facial height sufficiently to achieve ideal facial proportions nor achieve long-term occlusal stability. Despite the need for surgical intervention to achieve satisfactory occlusal and esthetic results, many patients with such deformities are still being treated in clinical practice by traditional orthodontic procedures, with less than ideal esthetic and/or occlusal results. The challenge to achieve efficient and stable treatment of this deformity has been met by the use of various surgical techniques in combination with orthodontic treatment. This combined surgical-orthodontic approach can provide increased treatment efficiency, long-term stability, and optimal esthetic results. The proper sequencing and correct selection of orthodontic mechanotherapy are essential to ensure the desired results. This article purposes to detail basic problems involved in diagnosis and treatment planning for the combined surgical-orthodontic approach to patients exhibiting Class II deep bite and decreased lower facial height. Orthodontic and surgical treatment objectives are explained, and representative case reports are presented and discussed to illustrate this method of treatment. Extraction patterns, control of the transverse dimension, arch wire selection, auxiliary wires, elastics, and extraoral appliance use are described. Surgically, the dentofacial disharmony associated with this deformity may defy treatment by surgical advancement of the mandible only. genioplasty, Le Fort I osteotomy, symphyseal osteotomy, anterior or total mandibular subapical osteotomy, body osteotomy, submental lipectomy, and rhinoplasty are adjunctive procedures that are described and may be used in concert with mandibular advancement surgery.- - - - - - - - - - ranking = 1keywords = adolescent (Clic here for more details about this article) |
