1/92. Treatment of a Class II division 1 anterior open bite malocclusion. A case report of an 11-year-old Caucasian female who presented with a Class II div I anterior open bite malocclusion. Overjet is 6 mm and the anterior open bite 2 mm. There was a history of digit sucking till she was eight years old. She was successfully treated by non-extraction with pre-adjusted Edgewise appliances and high-pull headgear for a period of 27 months. ( info) |
2/92. Treatment of a Class III anterior open bite malocclusion: a combined orthodontic and orthognathic surgical approach. Case report of an adult Caucasian female aged 23 years and nine months who complained of some difficulty in chewing and talking. Patient was diagnosed to have a mild Class III skeletal malocclusion with an anterior open bite of 4 mm. Treatment included combined orthodontic and orthognathic surgical approach. Surgery included surgically assisted maxillary expansion, advancement and impaction, a mandibular setback and a vertical, antero-posterior reduction genioplasty. The present case report illustrates a coordinated orthodontic and orthognathic surgical approach in the treatment of skeletal open bite deformities. ( info) |
| mandibular advancement appliances (MAA) have been established as an alternative treatment option for obstructive sleep apnea (OSA). Although the therapeutic effect of these devices has been proven both clinically and polysomnographically through various studies, there are very few follow-up examinations in existence concerning possible dental side effects caused by the MAA. However, if lifelong treatment of OSA is considered, these follow-up examinations are of utmost importance. This article presents 2 cases with unexpected dental side effects and occlusal alterations caused by MAA therapy. ( info) |
4/92. Schinzel-Giedion syndrome: interesting facial and orodental features, and dental management. Schinzel-Giedion syndrome comprises multiple congenital anomalies. The orofacial features include coarse facies, frontal bossing, ocular hypertelorism, anterior open bite and macrodontia. Two cases are presented in which the presence of specific craniofacial anomalies with bilateral hydronephrosis confirmed the diagnosis. In one patient, bottle-feeding was associated with caries in maxillary central and lateral incisors, but the second patient was permanently tube fed and did not experience any dental caries. Clinical management of these patients requires a coordinated approach from a team of medical and dental specialists. ( info) |
5/92. The Garcia Distraction Appliance: treatment of the TMD patient with an anterior open bite. A temporomandibular joint case with an anterior open bite and a high mandibular plane angle was treated by erupting the posterior teeth after creating a posterior open bite using a Garcia Distraction Appliance and a Garcia Pivot Splint.

6/92. Traumatic chronic TMJ dislocation: report of an unusual case and discussion of management. Dislocation of the temporomandibular joint (TMJ) is most often spontaneous, but it can be associated with direct or indirect head and neck trauma. The disorder may be treated in general by simple closed techniques, if managed acutely. If the dislocation becomes chronic, however, open reduction is usually required. The article discusses various methods for an open surgical approach described in the literature. A case of a prolonged TMJ dislocation is presented, involving a severe bilateral mandibular dislocation with the condyles displaced into the infratemporal fossa and the lateral poles of the condyles articulating on the inner aspect of the zygomatic arch. An open approach, involving masseter, temporalis, and the medial pterygoid muscles, was utilized, followed by the use of scissors mouth props, Erich arch bars, and postoperative elastic traction.

7/92. The importance of the seated condylar position in orthodontic correction. It has been proposed that the discrepancy between the seated and unseated condylar position be identified and eliminated when the occlusion is reorganized. Identification of this discrepancy is most accurately accomplished through the use of diagnostic casts that have been taken from a deprogrammed patient and mounted in the seated condylar position on a semiadjustable articulator through an estimated facebow transfer. The amount and direction of any discrepancy is determined three dimensionally with condylar position instrumentation. ( info) |
8/92. Seckel syndrome: report of a case. An interesting case of a seven years old boy with a combination of clinical, genetic, radiological, pathologic and dental findings is presented in view of Seckel syndrome literature. General appearance of the patient was characterized by small forehead, posteriorly slanted ears, slightly beaked nose, midfacial hypoplasia very stunted stature with microcephaly. He had borderline mental retardation with normal motor development. Class II dentoskeletal pattern with mild overjet and open bite, congenitally missing permanent teeth, microdontia, enamel hypoplasia, taurodontism and dentinal dysplasia was observed according to the clinical and radiographic examination. In conclusion, Seckel syndrome is not encountered routinely in dental clinics, this case illustrates the importance of dental care in such a rare condition. ( info) |
9/92. amelogenesis imperfecta: diagnosis and resolution of a case with hypoplasia and hypocalcification of enamel, dental agenesis, and skeletal open bite. A case of amelogenesis imperfecta with hypoplasia, hypocalcification of the enamel, congenital absence of teeth 12 and 22, delayed eruption of tooth 23, edge-to-edge incisal relationship, open bite, and bilateral posterior cross bite at the level of the first and second premolars is presented. Lateral skull teleradiography indicated a Class III skeletal pattern of maxillary origin associated with a dolichofacial pattern with multiple indicators of facial hyperdivergence. The patient presented a major esthetic abnormality of the face and required orthodontic treatment prior to a prosthetic solution with full-coverage metal-ceramic crowns in both the maxilla and the mandible. The diagnosis of cases such as this one and the therapeutic implications from an orthodontic and prosthetic standpoint are reported. ( info) |
10/92. A less-invasive approach with orthodontic treatment in Beckwith-Wiedemann patients. The beckwith-wiedemann syndrome (BWS) is a rare genetic disorder, linked to an alteration on the short arm of chromosome 11 that comprises multiple congenital anomalies. macroglossia is the predominant finding, with subsequent protrusion of dentoalveolar structures, which results in a protruding mandible, anterior open bite, abnormally obtuse gonial angle and increased mandibular length. A less-invasive treatment with orthopaedic appliances in a patient with early tongue reduction is presented. This work summarizes the oral signs linked to macroglossia, and highlights the influence of macroglossia on mandibular growth structures. In our opinion, glossotomy could be carried out in the paediatric patient as a preventive measure in that it curbs the tongue's influence on skeletal growth and dramatically reduces the duration and extensiveness of subsequent treatment.
