1/14. 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.

2/14. Menkes disease: report of two cases.

    Menkes disease is a rare, autosomal recessive disorder characterized by neuronal degeneration, abnormal hair, malformed connective tissue, mental retardation, and a life span of three years. Previously reported dental findings include a high arched palate, delayed eruption of secondary dentition, and open bite. The case of twin seven-year-old males with Menkes disease is presented, along with previously unreported dental findings of spindle-shaped root resorption patterns on the primary maxillary central and lateral incisors.

3/14. Treatment of severe mandibular prognathism in combination with maxillary hypoplasia: case report.

    We performed a Le Fort I osteotomy and sagittal split ramus osteotomy (Obwegeser-Dal Pont) combined with mandibular anterior segmental osteotomy without tooth extraction for a patient with severe mandibular prognathism accompanied by a hypoplastic maxilla, anterior open bite and normal anterior mandibular vertical dimension. The results of facial appearance and occlusion were excellent. This combined surgical method appears to be satisfactory for treating severe mandibular prognathism with hypoplastic maxilla.

4/14. Indications and procedures for segmental dentoalveolar osteotomy: a review of 13 patients.

    The authors evaluated the surgical area, indications, and procedures for segmental dentoalveolar osteotomy carried out on 16 jaws in 13 patients treated at the Department of Oral and Maxillofacial Surgery, Kobe University Graduate School of medicine, between 1990 and 2001. osteotomy was indicated mainly in cases where tooth repositioning by orthodontic treatment was limited, where social conditions (e.g., age, time, finances) precluded orthodontic treatment, or where revision of orthodontic or surgical treatment was required. In cases of maxillary anterior segmental dentoalveolar osteotomy, the modified Wunderer method was used, where after an incision was made in the palatal mucosa, a mucoperiosteal flap was abraded as much as possible until the area of the osteotomy on the palatal side could be visualized. In maxillary posterior segmental dentoalveolar osteotomy, the operation was carried out in 2 stages because of the risk of necrosis of the bone fragments. In the first stage, an osteotomy was carried out on the vestibular side, since the vestibular gingival pedicle was intact. In the second stage, 3 weeks later, another osteotomy was performed after the palatal mucoperiosteal flap was abraded to visualize the area of the osteotomy as well as that of the maxillary anterior segmental dentoalveolar osteotomy.

5/14. Mandibular symphyseal distraction and its geometrical evaluation: report of a case.

    In this report, the case of a patient who has been treated with a different use of a tooth-borne custom-made mandibular symphyseal distraction device is presented. The difference in the application is that the distal arm of the device was sectioned during the retention phase to allow the possible relapse of displaced condyles to their original positions while the labial segment expansion is being maintained. The effect of this procedure was also evaluated on a geometrical model using measurements from the patient's cast. We conclude that symphyseal distraction is an effective and fast method of correcting orthodontic anomalies. The effect of the procedure on the condyle was only 3 degrees of distolateral rotation as calculated using the geometrical model.

6/14. An adolescent case of anterior open bite with masticatory muscle dysfunction.

    In adolescence an open bite is likely to be induced by various causes, and most patients with open bite show masticatory muscle dysfunction. The orthodontic correction of an open bite may lead to the recovery of harmonious stomatognathic function. This article reports treatment for a 12-year and 10-month-old female patient with an anterior open bite. She complained of occlusal disturbances due to an anterior open bite. Before the eruption of the upper second molars, she recognized the presence of occlusal contacts between the upper and lower anterior teeth. Before treatment, the activity of the masticatory muscles was relatively low during clenching. An upper lingual arch with an accessory spring to eliminate the premature contact and to improve the anterior open bite plus conventional fixed appliances for tooth alignment was selected as the treatment plan. Immediately after improvement of the open bite, the muscle activity became slightly greater than that at the initial stage. The total treatment time was 13 months. After treatment, an acceptable occlusion was achieved, the masticatory muscles were working harmoniously, and their activity was much higher than that at the initial stage. After a 2-year retention period, an acceptable occlusion was maintained without recurrence of the open bite, indicating a long-term stability of occlusion. The result of this treatment indicated that correction of open bite is of great importance for prevention of skeletal impairment and recovery of harmonious stomatognathic function lost by an unstable occlusion.

7/14. Orthodontic fine adjustment after vertical callus distraction of an ankylosed incisor using the floating bone concept.

    The outcome of vertical callus distraction of a segment of tooth-supporting alveolar process might be functionally and esthetically unsatisfactory because of the unidirectional impact of intraoral distraction devices. In this case report, we describe how, with a shortened consolidation phase and application of the floating bone effect, the tooth-supporting osteotomy segment can be successfully aligned 3 dimensionally. We applied orthodontic force systems that went beyond the unidirectional vector preset by the mechanical properties of the distraction device.

8/14. Interdisciplinary treatment including forced extrusion and reintrusion of a traumatized mandibular incisor for a patient with Class II Division 1 skeletal open bite.

    A woman with Class II Division 1 long-face syndrome characteristics had a history of facial trauma, dentoalveolar fracture of her mandibular anterior teeth, and temporomandibular joint pain. The pretreatment apical radiograph showed a large area of external root resorption of the mesial surface of the mandibular left central incisor. To arrest the external root resorption, the mandibular left central incisor was extruded. During extrusion, sequential apical radiographs were taken. As the tooth moved away from the site of osteoclastic activity, resorption ceased, and repair took place on the root surface. At this time, the mandibular left central incisor was intruded, the mesial defect self-repaired, the tooth remained vital, and the periodontial ligament was intact. The biologic bases for this cessation of resorption and the repair of the tooth's surface are presented.

9/14. amelogenesis imperfecta: the multidisciplinary approach. A case report.

    amelogenesis imperfecta is a hereditary developmental disorder of the dental enamel, in both primary and permanent dentition. The main clinical characteristics are extensive loss of tooth tissue, poor esthetics, and tooth sensitivity. Transmission of the gene takes place by either autosomal, dominant X-linked, or recessive modes. This clinical report describes a treatment sequence based on a multidisciplinary approach. A 21-year-old girl with hypoplastic amelogenesis imperfecta was referred to the Ege University School of dentistry clinic. She was concerned about the poor appearance and sensitivity of her teeth. The patient presented with an anterior open bite, although orthodontic treatment had been completed previously. Periodontal gingivectomy of her posterior teeth followed by endodontic treatment where indicated was proposed. The prosthodontic treatment consisted of metal ceramic fixed partial dentures of precious alloy. At the end of treatment, function and esthetics were improved to a level acceptable to both the patient and the dental team.

10/14. The benefits of early orthodontic treatment.

    Despite the recent recommendation by the American association of Orthodontists and Dentofacial orthopedics that orthodontists begin screening patients by age 7, it is the author's experience that the majority of orthodontists do not treat children prior to the eruption of permanent teeth and do not use functional appliances. This leads many general dentists to provide orthodontic services to their younger patients because local orthodontists do not or will not treat them. This article seeks to encourage all general dentists, pediatric dentists, and orthodontists to learn how to use functional appliances to significantly improve the health and appearance of younger patients.
