1/18. Congenital unilateral fusion of the maxilla and mandible.We present an uncommon severe first branchial arch congenital malformation, in which complete unilateral bony fusion between the maxillary and mandibular processes was found in a newborn exposed to carbamazepine medication all through pregnancy. This condition interferes with oral feeding, intubation, growth and development. In a review of previously reported cases it was found that this anomaly was commonly associated with other abnormalities. The etiology of this malformation was uncertain in our case, as carbamazepine was not proven to be the definite cause.- - - - - - - - - - ranking = 1keywords = process (Clic here for more details about this article) |
2/18. Autosomal dominant osteosclerosis: report of a kindred.Autosomal dominant osteosclerosis (ADO), a rare inherited craniotubular bone disorder, is a generalized hyperostosis that manifests itself as increased cortical thickening of the skull, mandible, metacarpals, metatarsals, long bones, vertebral bodies, ribs, and clavicles. jaw abnormalities, which clinically resemble the widening and deepening of the mandible seen in cherubism, begin in childhood and have been reported to stabilize after puberty. Teeth and alveolar bone are normal. ADO must be distinguished from Van Buchem's disease, which is characterized by elevated serum alkaline phosphatase, neurologic complications, exopthalmos, periosteal excrescences, and an autosomal recessive pattern of inheritance, as well as from other craniotubular bone disorders such as osteopetrosis. We present clinical and radiographic documentation of members of a kindred representing 4 generations affected with ADO. At initial examination of the proband, a differential diagnosis included cherubism, fibrous dysplasia, osteopetrosis, and Paget's disease. Radiographic examination revealed extensive radiopacity of the inferior border and basal bone of the mandible. The proband's clavicles and humerus were also affected. All family members examined were similarly affected and had mandibular and palatal tori. Authors of a previously published report on the dental and dentoalveolar management of patients with craniotubular bone disorders have recommended prophylactic antibiotics to minimize risk of osteomyelitis in all such cases. The members of our kindred received extensive dental treatment before diagnosis, including extractions of severely carious teeth, preprosthetic dentoalveolar surgery, and endodontic therapy; there was no incidence of osteomyelitis or postsurgical complications. Therefore, the use of prophylactic antibiotics may not be warranted in patients with ADO who have otherwise normal medical histories.- - - - - - - - - - ranking = 686.44766025549keywords = alveolar (Clic here for more details about this article) |
3/18. Total mandibular alveolar osteotomy in the management of skeletal (infantile) apertognathia.When intraoral access is adequate and other physical characteristics are satisfactory, total mandibular alveolar osteotomy can be used effectively to correct skeletal (infantile) apertognathia. The procedure, not frequently used, resulted in significant improvement of a massive open bite in a 15-year-old girl.- - - - - - - - - - ranking = 1144.0794337591keywords = alveolar (Clic here for more details about this article) |
4/18. Transmission of the dysgnathia complex from mother to daughter.We report the first observation of parent-to-child transmission of dysgnathia, a rare disorder characterized by severe mandibular hypoplasia or agenesis, ear anomalies, microstomia, and microglossia. Patient 1 was noted prenatally by ultrasound to have severe micrognathia and, after birth, abnormal ears with canal stenosis and non-contiguous lobules located dorsally to the rest of the pinnae, normal zygomata, severe jaw immobility and microstomia with an opening of only 4 to 5 mm, hypoplastic tongue, and cleft palate. The 21-year-old mother of patient 1 was born with severe micrognathia requiring tracheostomy, microglossia, cleft palate with filiform alveolar bands, abnormal pinnae, and decreased conductive hearing. Dysgnathia is thought to result from a defect in the development of the first branchial arch. A similar phenotype has been seen in Otx2 haplo-insufficiency and endothelin-1 homozygous null mice, suggesting that these genes contribute to branchial arch development. Our report of a long-surviving mother and her daughter with non-syndromal dysgnathia may lead to identification of the molecular basis of these findings and provide insight into the genetics of first branchial arch formation. The survival of patient 1 and patient 2 beyond the neonatal period has implications for improvements in prenatal diagnosis and counseling and for neonatal treatment of this condition.- - - - - - - - - - ranking = 228.81588675183keywords = alveolar (Clic here for more details about this article) |
5/18. Bilateral hyperplasia of the mandibular coronoid processes associated with the nevoid basal cell carcinoma syndrome in an Italian boy.In this report we present a subject affected by nevoid basal cell carcinoma syndrome (NBCCS), showing also bilateral mandibular coronoid processes hyperplasia, a hitherto unreported association. Our observation of bilateral hyperplasia of the mandibular coronoid processes in a boy with NBCCS may prompt a retrospective and prospective review of other patients affected by this syndrome in order to establish if this anomaly is part of it.- - - - - - - - - - ranking = 6keywords = process (Clic here for more details about this article) |
6/18. "Distraction" of grafted alveolar bone in cleft case using endosseous implant.OBJECTIVE: Presentation of a specific surgical technique of vertical alveolar ridge distraction performed on an alveolar bone graft 1 year after the primary grafting procedure designed to correct a labioalveolar cleft. The graft had not obtained the results desired and presented heavily scarred mucosal tissue. TECHNIQUE: A dental implant placed within the graft once it has been entirely freed by osteotomies functions as an endless screw. To avoid vascular risk, the alveolar bone graft is detached as a whole along its total height. Consequently, no bone remains above it to provide support for a conventional alveolar distractor. An osteosynthetic miniplate, fastened in a horizontal position beneath the nasal mucosae above the graft, is used to replace the missing bony support and to stabilize the implant, which activates the distraction process. PATIENT: This study is based on our first clinical case with a follow-up of 18 months at present. RESULT: A vertical displacement of the entire graft was achieved, including its attached mucosal layer, which repositioned both bone and mucosa on a far better level in the cleft area. Thus, a normal length of abutment was obtained permitting prosthetic rehabilitation based on the same endosseous implant, which was left in place within the graft. CONCLUSION: This technique may prove particularly helpful in certain cases in which a primary alveolar bone grafting procedure has produced borderline results. In such cases, on the one hand, neither the reasonably satisfactory volume of the bone graft itself nor the poor quality of its scarred mucosal tissue argue in favor of a secondary grafting procedure. On the other hand, it is impossible to resort to currently available alveolar distracters since our choice of techniques leaves no bone support above the graft.- - - - - - - - - - ranking = 2517.9747542701keywords = alveolar, process (Clic here for more details about this article) |
7/18. Surgical and prosthodontic treatment alternatives for children and adolescents with ectodermal dysplasia: a clinical report.ectodermal dysplasia with oligodontia and anodontia is characterized by absence or deficiency of the alveolar ridges. The optimal surgical and prosthetic approach varies in relation to patient age and the amount of bone that is present. This clinical report presents rehabilitation alternatives for ectodermal dysplasia in children and adolescents.- - - - - - - - - - ranking = 228.81588675183keywords = alveolar (Clic here for more details about this article) |
8/18. Rigid external distraction using skeletal anchorage to cleft maxilla united with alveolar bone grafting.OBJECTIVE: documentation of the application of maxillary distraction osteogenesis using rigid external distraction (RED) with skeletal anchorage combined with predistraction alveolar bone grafting (ABG) in cleft maxilla. DESIGN: Case report. PATIENT: A patient with numerous congenital missing teeth and severe maxillary deficiency related to complete bilateral cleft lip and palate with large alveolar bone defect. INTERVENTION: The patient received preoperative orthodontic treatment, predistraction ABG, and maxillary distraction osteogenesis using RED with skeletal anchorage. RESULTS: Predistraction ABG completely united the cleft maxilla. The united maxilla was successfully advanced by the RED system with skeletal anchorage, despite unsound dentition with numerous congenital missing teeth. CONCLUSION: The present study demonstrates that the combination of predistraction ABG and RED system with skeletal anchorage is effective for the treatment of severe maxillary deficiency related to complete bilateral cleft lip and palate with large bone defect and numerous congenital missing teeth.- - - - - - - - - - ranking = 1372.895320511keywords = alveolar (Clic here for more details about this article) |
9/18. Bilateral hyperplasia of the coronoid processes: clinical report.Monolateral or bilateral hyperplasia of the coronoid processes of the mandible is a rare disorder resulting in reduction of mouth opening because of the unnatural contact of the coronoid process with the zygomatic bones.

10/18. Elongated mandibular coronoid process as a cause of mandibular hypomobility.There are multiple factors in cases of mandibular hypomobility. One of these factors is elongated coronoid process. Two cases are presented to illustrate elongated coronoid process leading to mandibular hypomobility to help prevent misdiagnosis by clinicians. Coronoid process elongation is a rare condition. Both cases reported here had pulpitis on the teeth, however endodontic treatment could not be performed due to the restricted mouth opening in both cases. There were clinical findings of restricted range of motion, especially during protrusive movements. The restrictive movements did not cause pain for either patient, and the patients were not aware of their restricted mouth opening. Panoromic radiographs were taken and evaluated. The radiographs showed elongated coronoid process bilaterally. Three-dimensional computerized tomography was taken in one case only, due to the patient's financial restrictions. In cases of restricted mandibular opening, elongated coronoid process must be considered when diagnosing the cause.- - - - - - - - - - ranking = 9keywords = process (Clic here for more details about this article) |
