1/17. Craniofacial characteristics of klippel-feil syndrome in an eight year old female.A female eight year, one month old patient with klippel-feil syndrome has been introduced. General appearance of the patient was characterized by short neck with limited head movements, craniofacial asymmetry, low posterior hairline and a short stature. Cephalometric analysis revealed a Class I dentoskeletal pattern with an excessive mandibular plane angle and fused cervical vertebrae. Panoramic radiogram showed congenitally missing lower second premolars and right central incisor.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
2/17. Laser irradiation inhibition of open gingival embrasure space after orthodontic treatment.The purpose of this study was to investigate the inhibitory effect of low-energy laser irradiation on an incidence of open gingival embrasure space after orthodontic treatment. The patient was a 20-year, 7-month-old Japanese female with an Angle Class I malocclusion and crowding in the mandible. Treatment consisted of extraction of maxillary and mandibular first premolars and use of the Edgewise technique. A Ga-Al-As diode laser was used to irradiate an area of 0.5 cm2 at the labial and lingual gingival papilla between the canines. The time of exposure was 6 minutes for 3 days, carried out between the relevelling and en masse stages of movement. The total energy corresponding to 6 minutes of exposure varied from 1.90 J/cm2. There was no further evidence of open gingival embrasure space, except at the mandibular central incisor. Further: an improvement in the gingival inflammation caused by a periodontal disease was observed, and periodontal pocket depth was maintained. These results suggest that low-energy laser irradiation may inhibit the incidence of open gingival embrasure space after orthodontic treatment.- - - - - - - - - - ranking = 47.643066964064keywords = mandible (Clic here for more details about this article) |
3/17. Multiple supernumerary teeth in association with malocclusion: report of two cases.Although multiple supernumerary teeth without any associated syndromes are rare, their occurrence can create a variety of clinical problems such as derangement of the occlusion, prevention of eruption of permanent teeth, damage to adjacent teeth, cystic degeneration and root resorption. Hence, clinical and radiographic evaluation of patients should always be thorough in order to detect their presence. Furthermore, because the clinical management of multiple supernumerary teeth poses a great challenge to clinicians, timely, appropriate consultation and interdisciplinary approach to treatment is extremely important. We report two cases, a 14 year-old boy with eight and a 13-year-old girl with seven supernumerary teeth not associated with syndromes. In the boy, the teeth were bilaterally distributed in all quadrants in the premolar regions, and in the girl they were distributed bilaterally in the premolar regions in the mandible and bilaterally distal to the upper third molars. The clinical implications and management are discussed.- - - - - - - - - - ranking = 47.643066964064keywords = mandible (Clic here for more details about this article) |
4/17. Long-term outcome in a patient with Class I malocclusion with severe crowding treated without extractions.The treatment of a patient with a Class I malocclusion with significant skeletal transverse maxillary discrepancy and severe crowding 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. Treatment included rapid palatal expansion to correct the transverse maxillary deficiency and to gain arch length. Long-term follow-up (20 years) with a stable result is reported.- - - - - - - - - - ranking = 47.643066964064keywords = mandible (Clic here for more details about this article) |
5/17. Lower incisor extraction in Class I and Class II malocclusions: case reports.After a brief discussion of the indications/contraindications of extracting lower incisors as part of orthodontic treatment, five case reports are presented. These cases highlight that extracting lower incisors can be an accepted orthodontic option, not only in compromised class III treatments, but also in Class I and Class II malocclusions.- - - - - - - - - - ranking = 2keywords = lower (Clic here for more details about this article) |
6/17. Treatment of a Class I malocclusion with severe bimaxillary protrusion.This report describes the treatment of a 20-year-old woman from nigeria who had severe bimaxillary dentolveolar protrusion. The main issue in determining the appropriate treatment plan was the severity of the dentoalveolar protrusion. Four first premolars were extracted to reduce lip procumbancy. The change in the patient's facial esthetics was dramatic. Significant retraction of the upper and lower lips was achieved, and lip eversion and dentoalveolar protrusion were significantly improved. As the lips were retracted, mentalis strain was reduced; this improved chin projection. This case report was presented at an AAO meeting as part of the ABO student case display. It was chosen by committee to be published in the AJO-DO.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
7/17. Definitive surgical correction of the deformity resulting from hemimandibular hyperplasia.INTRODUCTION: The asymmetric deformity of the mandible resulting from the rare condition of hemimandibular hyperplasia has posed a challenge for aesthetic surgical correction. The literature relating to this condition is reviewed and the results of treatment in a series of patients described. MATERIAL AND methods: A series of treated patients is reviewed and the results of surgery illustrated and discussed. A maxillary Le Fort I osteotomy is first performed where levelling of the occlusal plane is required. The mandibular surgical technique commences with an extended sagittal ramus osteotomy with dissection of the inferior dental neurovascular bundle completely free of the mandible up to and including the mental foramen. The proximal fragment is then rotated cranially leaving undisturbed the soft tissue attachments at the inferior border, with corresponding bone reduction at the upper border. The inferior border of the distal fragment is then reduced to match the new position of the lower border of the proximal fragment, the neurovascular bundle repositioned, and rigid fixation applied. Finally, a straightening genioplasty is performed. RESULTS: It was possible to overcome the technical and anatomical difficulties associated with correction of this hemimandibular deformity and to achieve a good aesthetic result with acceptable facial symmetry when applying this surgical technique in 3 patients. CONCLUSION: Hemimandibular hyperplasia can be surgically corrected with good aesthetic and functional results and minimal morbidity.- - - - - - - - - - ranking = 96.286133928129keywords = mandible, lower (Clic here for more details about this article) |
8/17. A mini-implant for orthodontic anchorage in a deep overbite case.This article describes the orthodontic treatment of a 19-year-old female patient with anterior crowding. There was a moderate arch length discrepancy in the lower dental arch, a significant deep overbite, and a "gummy smile." We inserted an orthodontic mini-implant as anchorage for the intrusion of the upper incisor segment, followed by alignment of the upper and lower dental arches with an edgewise appliance without tooth extraction. The overbite was corrected from 7.2 mm to 1.7 mm by upper incisor intrusion, and the gummy smile was improved. Good occlusion and facial esthetics were achieved, and these results have been maintained for two years after completion of the active treatment.- - - - - - - - - - ranking = 2keywords = lower (Clic here for more details about this article) |
9/17. 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 = 4keywords = lower (Clic here for more details about this article) |
10/17. Chincup therapy for a young woman with anterior displacement and obtuse angle of the mandible in Class I malocclusion.INTRODUCTION: Dolichofacial skeletal patterns are a challenge for the orthodontist. Even when treatment for a long-face patient begins before the adolescent growth spurt, excellent compliance is generally needed. The patient whose care is presented here started treatment at age 14. RESULTS: The extraction of 4 premolars, rapid palatal expansion, and excellent compliance wearing a combination occipital and vertical-pull chincup over a 2-year period led to good results at age 16, with minimal dental or skeletal relapse at age 18 years 5 months.- - - - - - - - - - ranking = 190.57226785626keywords = mandible (Clic here for more details about this article) |
