1/30. Treatment of an impacted dilacerated maxillary central incisor.Impacted incisor With Dilaceration refers to a dental deformity characterized by an angulation between crown and root causing noneruption of the incisor. Surgical extraction used to be the first choice in treating the severely dilacerated incisor. In this article, a horizontally impacted and dilacerated maxillary central incisor was diagnosed radiographically. By combining two stages of the crown exposure surgery with light force orthodontic traction, the impacted dilacerated incisor was successfully moved into proper position. However, long-term monitoring of the stability and periodontal health is critical after orthodontic traction.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/30. open bite, dental alveolar protrusion, class I malocclusion: A successful treatment result.This case report describes the treatment of a dentoalveolar protrusion, Class I malocclusion with an anterior open bite. The 21-year-old woman presented with a significant anteroposterior and vertical skeletal discrepancy. Her face was convex with procumbent lips. Intraorally, she had an anterior open bite of 4 mm, mild crowding, and an overjet of 4.5 mm. First premolar extractions in conjunction with tongue therapy and high pull headgear were used to reduce protrusion and close anterior open bite. Modification of a tongue thrust habit allowed conventional orthodontic treatment to correct this significant malocclusion and provide stability over the last 4 years.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/30. Treatment of a Class I bimaxillary protrusive malocclusion with a high mandibular plane angle: An American Board of orthodontics case report.A case report of the orthodontic treatment of a male adolescent with a Class I bimaxillary protrusive malocclusion, complicated by a vertical growth pattern and high mandibular plane angle. Treatment consisted of extraction of maxillary second premolars, mandibular first premolars, use of a transpalatal bar, occipital pull headgear, and light wire mechanics. An acceptable result was achieved, with a decrease in the facial axis, decrease in lip strain, and an attractive full smile. 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 = extraction (Clic here for more details about this article) |
4/30. Orthodontic treatment of a patient with multiple supernumerary teeth and mental retardation.Supernumerary teeth may lead to impaction or ectopic eruption of maxillary incisors, crowding, oronasal fistula, follicular cyst, migration of adjacent teeth and root resorption. In this presentation, an 11-year-old male patient with 4 supernumerary teeth in the maxillary anterior region and a slight mental retardation problem will be presented. After extraction of the supernumerary teeth, the large space created by distal migration of central incisors was closed by orthodontic treatment. Although initial patient compliance was weak and caused difficulties in the course of treatment, orthodontic treatment was completed successfully.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/30. Treatment of a Class I malocclusion with a carious mandibular incisor and no Bolton discrepancy.Occasionally orthodontists must plan treatment for a patient with extensive caries or a traumatic injury to one mandibular incisor. If the patient has a Bolton discrepancy, one treatment option could involve extraction of the affected mandibular incisor. However, if the patient does not have a Bolton discrepancy and a mandibular incisor is extracted, the treatment becomes more complicated. This case report will present and discuss the ramifications of extracting one mandibular incisor in a patient without an anterior tooth-size discrepancy. The CDABO Student Case Selection Committee chose this case for publication.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/30. 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 = 1keywords = extraction (Clic here for more details about this article) |
7/30. A case of bilateral supplemental maxillary central incisors.A case of bilateral supplemental maxillary central incisors is presented. Treatment comprised of extraction of one supplemental and two lateral incisors, preservation of one supplemental incisor, finishing with a 'Cyclops' arrangement of the teeth. The handling of supernumerary teeth in general is discussed.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
8/30. Nonextraction treatment of Class I malocclusion with severe anterior crowding: a case report.The treatment of a 12-year-old girl with a Class I malocclusion, severe anterior crowding, and posterior crossbite is described. The patient, who had limited growth potential and exhibited a straight facial profile, was treated with rapid maxillary expansion and nonextraction edgewise mechanics.- - - - - - - - - - ranking = 5keywords = extraction (Clic here for more details about this article) |
9/30. An unexpected growth pattern: considerations in management.A case study spanning 16 years is presented. Routine treatment with serial extraction and an edgewise appliance for a Class I crowded occlusion began when the patient was 8 years old. By the time the patient was 17, his dentition had evolved, because of unanticipated growth, into a Class III malocclusion with complete-arch crossbite. The question of whether it is most appropriate to treat this patient in one or two surgical procedures is discussed, and some controversial aspects and concerns are presented.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/30. Extraction of four first molars: a case for a general practitioner?It has been suggested that the extraction of four first molars 'doubles the treatment time and halves the prognosis' (Mills). It is also thought by some that these cases are unsuitable for treatment by General Dental Practitioners. The aim of this article is to illustrate that, with careful case selection, space analysis and good anchorage control, first molar extraction cases can be relatively straightforward- - - - - - - - - - ranking = 2keywords = extraction (Clic here for more details about this article) |
