1/13. Orthodontic treatment in handicapped children: report of four cases.Mentally and physically handicapped children show in the orofacial system motor-sensitivity disturbances and malocclusions of varying severity. These dysfunctions affect the breathing and speech ability and inhibit the food intake. Myotherapeutic exercises for strengthening of lip and tongue muscles and orthodontic treatment of the malocclusions help provide esthetic and functional improvements in these patients. The limited compliance necessitates a differentiated procedure during the diagnostic and therapeutic process and demands compromises in some cases.- - - - - - - - - - ranking = 1keywords = malocclusion (Clic here for more details about this article) |
2/13. Dental malocclusion and upper airway obstruction, an otolaryngologist's perspective.INTRODUCTION: This paper, through the presentation of eight case reports and a limited literature review, attempts to illustrate the negative effect that upper airway obstruction can have on developing dental occlusion and the positive effect that upper airway relief can have on the 'normalization' of various malocclusion patterns believed to be related to chronic obligate mouth breathing. OBJECTIVE: To study the effect of airway relief (usually through tonsillectomy and/or adenoidectomy) on various patterns of dental malocclusion. methods: Children coming to the office of the lead author (D.J.W.) found to be obligate mouth breathers and who also had dental malocclusion had Polaroid 'bite' pictures taken at the time of their initial visit. One year or more after their surgery for upper airway relief (tonsillectomy and adenoidectomy in these cases) a second 'bite' photograph was taken and compared to the first. RESULTS: In all cases selected in this study there was observed improvement in their dental occlusion within a year following surgery to improve their breathing. CONCLUSION: It is the opinion of the authors of this paper that upper airway obstruction may have a negative effect on the developing transitional dental occlusion and that eliminating the cause of upper airway obstruction can lead to 'normalization' of occlusion in such children. Further orthodontic corrective modalities may be required for optimal occlusal results.- - - - - - - - - - ranking = 3.5keywords = malocclusion (Clic here for more details about this article) |
3/13. Long-term outcome of skeletal Class II Division 1 malocclusion treated with rapid palatal expansion and Kloehn cervical headgear.The treatment of a patient with a skeletal Class II Division 1 malocclusion, with excessive overjet, complete overbite, airway obstruction, and severe arch length deficiency in the mandibular dental arch, is presented. The maxilla was narrow compared with the mandible, and the posterior teeth were compensated, with the maxillary teeth inclined buccally and the mandibular teeth inclined lingually. The palatal vault was extremely high. Treatment included rapid palatal expansion to correct the transverse maxillary deficiency and Kloehn cervical headgear to correct the anteroposterior skeletal discrepancy. Long-term stability (12-year follow-up) is reported.- - - - - - - - - - ranking = 2.5keywords = malocclusion (Clic here for more details about this article) |
4/13. Craniofacial morphology in an unusual case with nasal aplasia studied by roentgencephalometry and three-dimensional CT scanning.OBJECTIVE: To examine the three-dimensional morphology of internal structures of the craniofacial region and present the orthodontic problems in an unusual case with nasal aplasia. PATIENT: The patient was an 11.5-year-old boy with aplasia of the nose and nasal cavity with extremely constricted nasopharyngeal airway. He did not have mental or somatic retardation. The patient had dacryostenosis. The morphology of the craniofacial structures was characterized by absence of septal structures, including cribriform plate, perpendicular plate of ethmoid bone, vomer, and septal cartilage; bony hypotelorism; midface hypoplasia; short and retrognathic maxilla with Class III jaw relationship; average mandibular plane angle; high arched palate; severe anterior open bite with bilateral posterior crossbites; and dental anomalies (agenesis of four maxillary permanent teeth, microdontia, taurodontism, and short roots). Thus, the patient had characteristic dentofacial phenotype, which might be caused by a combination of the primary anomaly and the functional disturbances secondary to the nasal obstruction.- - - - - - - - - - ranking = 0.00015977005934522keywords = angle (Clic here for more details about this article) |
5/13. Early orthodontic treatment and long-term observation in a patient with Morquio syndrome.Early orthodontic treatment and long-term observation in a patient with Morquio syndrome were demonstrated. To date, there are no case reports describing orthodontic treatment in such a patient. The patient showed spaced maxillary and mandibular arches with a tongue thrust habit at age seven years eight months. She also showed a protruded upper lip, labial inclination of the upper and lower anterior teeth, and thin enamel. The tongue thrust habit disappeared after the application of a removable orthodontic appliance. The spaced dentition in the upper and lower arches improved after treatment with a fixed appliance with closing loop arch wire (0.017 x 0.025") and bands on the upper and lower molars. We did not use an edgewise appliance because of the thin enamel. The protruded upper lip and labial inclination of the upper and lower anterior teeth were also improved after treatment, but optimal intercuspation of the teeth was not achieved. However, optimal intercuspation of the teeth was achieved after long-term observation and the masticatory function was improved. It was suggested that early orthodontic treatment could improve the malocclusion in a patient with Morquio syndrome and that improvement of masticatory function could be achieved during a long-term retention period.- - - - - - - - - - ranking = 0.5keywords = malocclusion (Clic here for more details about this article) |
6/13. Dynamic MRI evaluation of tongue posture and deglutitive movements in a surgically corrected open bite.tongue thrust usually develops in the presence of anterior open bite in order to achieve anterior valve function. In the literature, tongue thrust is described both as the result and the cause of open bite. If it is an adaptation to malocclusion, then tongue posture and deglutitive tongue movements should change after treatment. In this case report, an adult who had skeletal open bite and Class II malocclusion caused by mandibular retrusion was treated surgically. The mandible was advanced in a forward and upward direction with a sagittal split osteotomy. The open bite and Class II malocclusion were corrected and an increase in the posterior airway space (PAS) was observed. Pretreatment and posttreatment dynamic magnetic resonance imaging (MRI) revealed that tongue tip was retruded behind the incisors and contact of the tongue with the palate increased. It was also determined that the anterior and middle portions descended, whereas the posterior portion was elevated at all stages. Advancement of the mandible, correction of open bite, and an increase in PAS affected not only the tongue posture and deglutitive movements, but also the breathing pattern of the patient.- - - - - - - - - - ranking = 1.5keywords = malocclusion (Clic here for more details about this article) |
7/13. Class I malocclusion with severe open bite skeletal pattern treatment.A case report of a Class I malocclusion with a severe skeletal open bite, excessive overjet, a high mandibular plane angle, and a forward maxillary rotation is presented. Treatment has eliminated the causative factors (i.e., mouth breathing, enamel hypoplasia of the first molars, and abnormal tongue posture and function). A normal growth pattern has been restored, ensuring a good and stable orthodontic result.- - - - - - - - - - ranking = 2.5001597700593keywords = malocclusion, angle (Clic here for more details about this article) |
8/13. A case of open bite with Turner's syndrome.The treatment of a skeletal Class III open bite malocclusion with Turner's syndrome is described. Although the patient had a negative overbite of 9 mm, a positive overbite of 2 mm was obtained through treatment, without any tooth extractions; however, an excessive vertical growth of the anterior regions was noted.- - - - - - - - - - ranking = 0.50056507418422keywords = malocclusion, tooth (Clic here for more details about this article) |
9/13. A dental Class III malocclusion treated to a full-cusp Class II molar relationship.A case report of a Class III dental malocclusion superimposed on a straight skeletal pattern is presented. The patient was a 14-year-old girl with limited growth potential. This case included congenitally missing maxillary permanent lateral incisors, impacted maxillary permanent canines, and bilateral posterior open bites. The patient's soft-tissue profile was normally convex. In addition to her malocclusion, the patient had a history of difficulty breathing through the nose. The general treatment included palatal expansion, protraction headgear, and comprehensive edgewise orthodontic therapy.- - - - - - - - - - ranking = 3keywords = malocclusion (Clic here for more details about this article) |
10/13. The stability of maxillary expansion.The assessment and treatment by rapid maxillary expansion of 516 cases referred by medical practitioners for the treatment of poor nasal airway is reported. The technique is simple and most suitable for the correction of crossbite and Class III malocclusion and for establishing a nasal airway in habitual mouth breathers with a history of ENT problems.- - - - - - - - - - ranking = 0.5keywords = malocclusion (Clic here for more details about this article) |
