1/19. Ridge augmentation using mandibular tori.A 19-year-old female was referred by her dental practitioner for the restoration of missing maxillary lateral incisors and canines. Ridge augmentation was required. This was undertaken using mandibular tori as the sites for harvesting bone. The grafting was successful and the spaces were subsequently restored using resin-bonded bridgework. The case reports that mandibular tori provide a local and convenient source of bone for ridge augmentation procedures.- - - - - - - - - - ranking = 1keywords = ridge (Clic here for more details about this article) |
2/19. Craniofacial and dental manifestations of proteus syndrome: a case report.The proteus syndrome is a rare congenital hamartomatous condition that is characterized by a wide range of malformations, sometimes involving the face. Common manifestations include partial gigantism, congenital lipomas, and plantar hyperplasia. In this report we describe the craniofacial clinicopathological development in a girl with proteus syndrome from age 6 to 20 years. The patient had pronounced hemifacial hypertrophy, exostoses in the left parietal region, and enlargement of the inferior alveolar nerve and mandibular canal in the affected region. The dental development of the affected left mandible and maxilla was characterized by extremely premature development and eruption of the primary and permanent teeth and by pronounced idiopathic root resorptions. The multidisciplinary management of the patient and the treatment outcome is reported. A review of the Proteus patients in the literature who exhibited manifestation in the craniofacial region is presented.- - - - - - - - - - ranking = 0.13964815187033keywords = alveolar (Clic here for more details about this article) |

4/19. minocycline-induced staining of torus palatinus and alveolar bone.BACKGROUND: minocycline hydrochloride, an analog of tetracycline, is widely used in the treatment of acne. Its use has been associated with discoloration of teeth, bone, and other tissues. methods: A case is presented involving a patient with minocycline-induced staining of the torus palatinus and alveolar bone. RESULTS: No treatment was rendered since the patient was not concerned with the appearance of the discoloration. The patient's dermatologist elected to change antibiotics. CONCLUSIONS: patients on long-term minocycline therapy should be made aware of the possibility of pigmentation of bone and soft tissue that may be reversible with discontinuation of therapy; however, minocycline-induced staining of the permanent dentition may not be reversible.- - - - - - - - - - ranking = 0.69824075935164keywords = alveolar (Clic here for more details about this article) |
5/19. Jacob's disease associated with temporomandibular joint dysfunction: a case report.Jacob's disease is regarded a rare condition in which a joint formation is established between an enlarged mandibular coronoid process and the inner aspect of the zygomatic body. Chronic temporomandibular joint (TMJ) disk displacement has been proposed as etiological factor of coronoid process enlargement. We present a 23-year-old woman with long-standing TMJ dysfunction and restricted interincisal opening, who developed a progressive zygomatic asymmetry. The patient underwent treatment by intraoral coronoidectomy and homolateral TMJ arthroscopy in the same surgery. The histopathological diagnosis of the coronoid sample was cartilage-capped exostoses with presence of articular fibrous cartilage. Although the low prevalence of this entity, it should be considered as a possible diagnosis in patients with progressive limitation of mouth opening, although a TMJ syndrome may be present as a cause of this entity.- - - - - - - - - - ranking = 0.062506699359536keywords = process (Clic here for more details about this article) |
6/19. The value of three-dimensional computed tomography in diagnosis and management of Jacob's disease.This study reports a case of Jacob's disease characterized with limited mouth opening due to bilateral coronoid hyperplasia forming pseudojoints with zygomatic arches. Magnetic resonance (MR) examination of temporomandibular joint (TMJ) is usually the imaging method chosen in patients with such symptoms. However, the coronoid processes can not be displayed because they are not included in field of view in MR imaging of TMJ. For that reason, these patients may be treated for a misdiagnosis of TMJ disorders. In this study, the aetiology and diagnostic methods of Jacob's disease, the pre-operative/post-operative role of three-dimensional computed tomography and some measurements used in diagnosis were evaluated.- - - - - - - - - - ranking = 0.031253349679768keywords = process (Clic here for more details about this article) |
7/19. Clinical and histologic evaluation of the use of mandibular tori as donor site for mandibular block autografts: report of three cases.The present paper reports on three patients who underwent localized alveolar ridge augmentation using block autografts harvested from the mandibular tori. Autogenous particulate bone graft was placed at the periphery of the block. Resorbable collagen membrane was placed above the graft material. Implant placement surgery followed at 6 to 16 months after bone grafting. During implant surgery, a biopsy was taken from the block autograft. Clinical evaluation revealed incorporation of the graft material at the recipient site. No donor site complication was noted. Histologic evaluation suggested that the block autograft was vital and in an active remodeling phase at the time of implant placement. Impressions were made intraorally before and 6 months after bone grafting. Laboratory measurements revealed 13% resorption at 6 months after bone grafting while 0.53 mL of ridge augmentation was achieved 6 months after bone grafting. Linear tomographs indicated 4.33 mm of lateral alveolar ridge augmentation. This report suggests that block autografts harvested from the mandibular tori may have the potential to maintain their vitality after bone grafting, while they may demonstrate resorption rates similar to those of autografts harvested from other intraoral donor sites.- - - - - - - - - - ranking = 1.7792963037407keywords = ridge, alveolar (Clic here for more details about this article) |
8/19. Craniofacial characteristics of proteus syndrome: two modes of abnormal growth.The dysmorphic growth patterns of the craniofacial skeleton are summarized in five patients with the proteus syndrome. Two different modes of abnormal growth are present. One mode involves focal overgrowth of membrane bones, producing multiple hyperostoses which result in progressive craniofacial disfigurement and asymmetry. The second mode involves overgrowth of cartilage in the condyle, resulting in dentofacial asymmetry. The phenotype of the craniofacial skeleton results from both processes. In terms of appearance, the mode involving hyperostosis seems more dramatic in most cases than the mode involving cartilage.- - - - - - - - - - ranking = 0.031253349679768keywords = process (Clic here for more details about this article) |
9/19. Subungual exostoses--clinicopathological and ultrastructural studies of three cases.Three patients with subungual exostoses, two involving the great toe and one the fourth toe, are presented. Local excision was performed, and the specimens were processed for light and electron microscopy. light-microscopic study revealed that the tumours consisted of a proliferative fibrocartilaginous cap that merged into mature trabecular bone at its base. Electron-microscopic examination revealed that the tumour was composed of two types of cells: one was rich in cell organelles including rough endoplasmic reticulum, well-developed golgi apparatus, and glycogen granules; the other cell had few such cell organelles. The former cells seemed to be osteoblasts actively engaged in bone formation, and the latter to be osteocytes related to those situated deeper in bone matrix in normal bone. However, ossification or calcification in subungual exostosis is rather casual, and osteocytes in this disorder may lack the capacity to elaborate compact bone.- - - - - - - - - - ranking = 0.031253349679768keywords = process (Clic here for more details about this article) |
10/19. Reduction of mouth opening due to mandibular coronoid progess enlargement. Report of a case.A case of unilateral mandibular coronoid enlargement associated with facial asymmetry and severe limitation of mandibular movement in a 19-year-old male patient is described. The indications for treatment and the types of surgical approach for removal of the enlarged process are discussed. The dual surgical approach required for resection of the coronoid in this case is described.- - - - - - - - - - ranking = 0.031253349679768keywords = process (Clic here for more details about this article) |
