1/66. The role of orthognathic surgery in the treatment of severe dentoalveolar extrusion.BACKGROUND: When mandibular molars are not replaced after extraction, the long-term problem of inadequate interarch space for either a fixed or removable prosthesis can occur. In the past, practitioners needed to decide whether to shorten the teeth, extract the supererupted maxillary molars to recapture space or leave the area unrestored. The authors present another option. CASE DESCRIPTION: A 61-year-old man was referred to a periodontist by his general dentist for placement of mandibular implants in the posterior sextant. Extreme supereruption of the maxillary dentoalveolar segment prevented restoration of the opposing edentulous area. An oral and maxillofacial surgeon performed a segmental osteotomy of the posterior right maxilla to gain needed interarch space. After the osteotomy was stabilized, the periodontist placed implants that were subsequently restored with a fixed prosthesis. CLINICAL IMPLICATIONS: The role of orthognathic surgery in treatment planning should not be overlooked in the comprehensive management of severe extrusion. It offers patients the opportunity to gain both function and esthetics that might otherwise be impossible.- - - - - - - - - - ranking = 1keywords = dentoalveolar, alveolar (Clic here for more details about this article) |

3/66. Orthodontic treatment for a patient with Pierre-Robin sequence complicated by juvenile periodontitis.OBJECTIVE: To arrest the advancement of periodontitis. PATIENT: A 17-year-old boy diagnosed with Pierre-Robin sequence at birth exhibited localized juvenile periodontitis. Severe bone loss and mobile teeth were localized in the incisors and molars, which were irregularly positioned, possibly associated with a residual scar from palatoplasty for a soft palate cleft at an early age. CONCLUSION: Combined orthodontic-periodontic-prosthodontic treatment arrested the advancement of the periodontitis and established a stable occlusion.- - - - - - - - - - ranking = 0.35403895314327keywords = periodontitis (Clic here for more details about this article) |
4/66. dyskeratosis congenita: report of a case.dyskeratosis congenita is a rare multisystem condition involving mainly the ectoderm. It is characterized by a triad of reticular skin pigmentation, nail dystrophy and leukoplakia of mucous membranes. Oral and dental abnormalities may also be present. Complications are a predisposition to malignancy and bone marrow involvement with pancytopenia. The case of a 14-year-old girl is described who presented with several of the characteristic systemic features of this condition, together with the following oral features: hypodontia, diminutive maxillary lateral incisors, delayed dental eruption, crowding in the maxillary premolar region, short roots, poor oral hygiene, gingival inflammation and bleeding, alveolar bone loss, caries and a smooth atrophic tongue with leukoplakia. Although this condition is rare, dental surgeons should be aware of the dental abnormalities that exist and the risk of malignant transformation within the areas of leukoplakia.- - - - - - - - - - ranking = 0.0012479008831441keywords = alveolar (Clic here for more details about this article) |
5/66. Effect of facial pressure garments for burn injury in adult patients after orthodontic treatment.pressure garments are commonly used to prevent and control hypertrophic scar tissue. Complications are unusual, though in children with facial burns, pressure garments may lead to skeletal and dental deformities. Studies in adolescents and adults are sparse. We describe a 24-year-old woman who sustained facial burns. Prior to injury, the patient had undergone premolar extraction in preparation for orthodontic treatment. Her post-burn care consisted of application of a Jobst pressure garment. After 2 months treatment, severe deformation of the dental-alveolar structure was observed. This reports suggests that adults after dental extraction are at a high risk of dental-alveolar deformities from pressure garments and might benefit from the use of occlusal wafers.- - - - - - - - - - ranking = 0.0024958017662882keywords = alveolar (Clic here for more details about this article) |
6/66. Rapid orthodontics with alveolar reshaping: two case reports of decrowding.Two case reports demonstrate a new orthodontic method that offers short treatment times and the ability to simultaneously reshape and increase the buccolingual thickness of the supporting alveolar bone. A 24-year-old man with a Class I severely crowded malocclusion and an overly constricted maxilla with concomitant posterior crossbites and a 17-year-old female with a Class I moderately to severely crowded malocclusion requested shortened orthodontic treatment times. This new surgery technique included buccal and lingual full-thickness flaps, selective partial decortication of the cortical plates, concomitant bone grafting/augmentation, and primary flap closure. Following the surgery, orthodontic adjustments were made approximately every 2 weeks. From bracketing to debracketing, both cases were completed in approximately 6 months and 2 weeks. Posttreatment evaluation of both patients revealed good results. At approximately 15 months following surgery in one patient, a full-thickness flap was again reflected. Visual examination revealed good maintenance of the height of the alveolar crest and an increased thickness in the buccal bone. The canine and premolars in this area were expanded buccally by more than 3 mm, and yet there had actually been an increase in the buccolingual thickness of the overlying buccal bone. Additionally, a preexisting bony fenestration buccal of the root of the first premolar was covered. Both of these findings lend credence to the incorporation of the bone augmentation procedure into the corticotomy surgery because this made it possible to complete the orthodontic treatment with a more intact periodontium. The rapid expansive tooth movements with no significant apical root resorption may be attributed to the osteoclastic or catabolic phase of the regional acceleratory phenomenon. Instead of bony "block" movement or resorption/apposition, the degree of demineralization/remineralization might be a more accurate explanation of what occurs in the alveolar bone during physiologic tooth movement in these patients.- - - - - - - - - - ranking = 0.0087353061820087keywords = alveolar (Clic here for more details about this article) |
7/66. Anterior mandibular dentoalveolar advancement utilizing lyophilized bone.patients with low angle Class II malocclusions complicated by strong nasal and chin profiles, interarch width discrepancies, and an exaggerated mandibular curve of Spee present several diagnostic and treatment problems. Various treatment possibilities are discussed and anterior mandibular dentoalveolar advancement is suggested as a treatment for these patients. Lyophilized, homologous bone is recommended for placement into the defects created by segmental advancement to avoid root resorption and ankylosis caused by autologous bone grafts. Finally, a modified incision is presented that facilitates watertight closure of the surgical wound.- - - - - - - - - - ranking = 1keywords = dentoalveolar, alveolar (Clic here for more details about this article) |
8/66. Guidelines for periodontal prostheses serve esthetic and functional demands: a case report.Periodontal-prosthesis guidelines have long been defined to specifically address dental reconstructions after moderate to advanced periodontal disease has occurred. More recently, specific dental techniques and materials have shown promise in addressing patients' increasing esthetic demands. However, treatment planning to achieve pleasing results for patients with advanced periodontitis requires a complex, multispecialty approach that is rarely discussed. A case report and literature review illustrate that the original periodontal-prosthesis guidelines not only remain useful today for obtaining esthetic results but also conform to recent understanding of maxillomandibular physiology.- - - - - - - - - - ranking = 0.050576993306181keywords = periodontitis (Clic here for more details about this article) |
9/66. Incomplete unilateral cleft of the primary palate: delayed secondary bone grafting combined with orthodontic treatment.The presence of a fissural lateral incisor in an alveolar cleft is not a common occurrence and, if one is present, must in most instances be removed because of microdontia or because it may compromise a bone graft. This case report presents an example of bone grafting carried out late in the secondary stage of the patient's dentition, in conjunction with retention of the fissural lateral incisor as requested by the patient, and shows an acceptable outcome from the points of view of both aesthetics and dento-alveolar health.- - - - - - - - - - ranking = 0.0024958017662882keywords = alveolar (Clic here for more details about this article) |
10/66. Report of a patient with hypoglossia-hypodactylia syndrome and a review of the literature.OBJECTIVE: To present the morphology of the extremities, craniofacial structures, and the oral cavity based on roentgencephalometry and three-dimensional computed tomography and magnetic resonance imaging scanning in a patient with hypoglossia-hypodactylia syndrome, discuss the orthodontic treatment method, and review the literature for the syndrome. PATIENT: The patient was a 6-year-old boy diagnosed with hypoglossia-hypodactylia syndrome at birth. He had hypodactylia as well as micrognathia with steep inclination of the anterior surface of the mandible in relation to the lower mandibular plane. He had missing mandibular incisors with concomitant bone defect limited to the associated alveolar ridge and an absence of any malformations in the mandibular ramus and condylar head. The patient had a bilateral scissors bite with an extremely constricted mandibular dental arch, skeletal Class II jaw relationship with an average mandibular plane angle and maxillary incisors inclined palatally. He had extremely reduced tongue size and hypertrophy of the floor of the mouth. Anomalies of the central nervous system were not observed. There was no evidence of hearing loss.- - - - - - - - - - ranking = 0.0012479008831441keywords = alveolar (Clic here for more details about this article) |
