1/18. Accuracy of integration of dental casts in three-dimensional models.PURPOSE: This study investigated errors occurring in three-dimensional (3D) models when plaster dental casts are integrated into them. MATERIALS AND methods: Three-dimensional milling models of three patients with a jaw deformity were fabricated using the Endoplan system (SPARC International Inc, Santa Clara, CA). After this, plaster dental casts were integrated into the 3D models using a face-bow transfer system. Two cephalograms were then compared, one obtained from the patient and the other obtained from the 3D model painted with contrast medium. RESULTS: In two cases, the reproducibility of the dental position as determined by angle analysis was within 2 degrees, and that determined by distance analysis was within 2 mm. However, errors over 4 degrees and 4.2 mm, respectively, were observed in one case. CONCLUSION: It is clinically important to confirm the accuracy of the 3D model by cephalometric analysis, and it may be necessary to reposition the dental model based on the results.- - - - - - - - - - ranking = 1keywords = deformity (Clic here for more details about this article) |
2/18. Cystic lymphangioma: its orofacial manifestations.A patient age five years, nine months with cystic lymphangioma was studied to determine the causes of malocclusion and the optimum time for its treatment. The main findings were unilateral anterior and posterior crossbite and displacement of the mandibular midline due to maxillary deformity and mandibular rotation. The force of the cystic lymphangioma mass caused deformity of the maxilla and rotation of the mandible. The patient had no functional impairment of speech or mastication. A decision was made to defer treatment of malocclusion until complete surgical excision of the cystic lymphangioma can be undertaken, thereby minimizing the chance of malocclusion re-occurrence.- - - - - - - - - - ranking = 2keywords = deformity (Clic here for more details about this article) |
3/18. osteogenesis imperfecta and orthognathic surgery: case report with long-term follow-up.osteogenesis imperfecta (OI) is the product of the abnormal synthesis and/or production of Type I collagen. Successful surgical management of extremity and spinal skeletal problems secondary to OI is documented in the orthopedic literature. Reports of successful facial skeletal surgery in all types of OI are encouraging. The purpose of this paper is to report on the long-term results of an orthognathic surgery patient successfully treated to correct a severe dentofacial deformity. The patient underwent an uncomplicated Le Fort I osteotomy with homologous interpositional bone grafts to advance and inferiorly reposition the maxilla. Clinically, the patient appeared to heal without difficulty, and a stable Class I skeletal and dental relationship was achieved. Nine years after surgery, the patient has a Class I occlusion, with maintenance of his facial height and skeletal relationship. Craniomaxillofacial surgery can be predictably performed in patients with OI as long as the surgeon maintains strict adherence to proper surgical technique and bears in mind the deficiencies of bone density and other possible medical complications.- - - - - - - - - - ranking = 4271.1223017533keywords = dentofacial deformity, dentofacial, deformity (Clic here for more details about this article) |
4/18. Lobster-claw syndrome.Lobster-Claw syndrome is a rare autosomal dominant, hand-foot malformation with Oro-dental features. This is a rare condition and from the available reports so far, cases being reported are less than 1%. Most reports have focused on the hand-foot deformity of this syndrome. This paper highlights the typical Oro-dental features associated with this syndrome such as retained deciduous teeth, hypodontia and variation in crown size, arch length and arch width.- - - - - - - - - - ranking = 1keywords = deformity (Clic here for more details about this article) |
5/18. Prosthodontic treatment of a patient with hemimandibular elongation: a clinical report.This clinical report describes prosthodontic treatment of a patient with hemimandibular elongation that resulted in significant dentofacial asymmetry. A maxillary metal-ceramic fixed dental prosthesis and crowns were fabricated. To eliminate the negative horizontal overlap, 3 mandibular teeth were reduced to the gingival level. The mandibular prosthetic restoration was completed with metal and composite resin using an electroforming technique.- - - - - - - - - - ranking = 258.65148158072keywords = dentofacial (Clic here for more details about this article) |

7/18. Reduction cheiloplasty: its role in the correction of dentofacial deformities.The presence of prominent lips is common in individuals with various dentofacial and craniofacial deformities. The aetiology must be diagnosed to differentiate between pseudo-macrochelia and true macrocheilia. When considering surgical correction of the prominent lip, a precise description of the location and the magnitude of the deformity is required. With careful treatment planning, proper sequencing of the treatment, and a good understanding of the various surgical techniques, optimum results can be achieved. These aspects will be discussed in detail illustrated with appropriate cases.- - - - - - - - - - ranking = 1294.2574079036keywords = dentofacial, deformity (Clic here for more details about this article) |
8/18. Surgical-prosthetic correction of dentofacial deformities.The rehabilitation of optimal masticatory function in many persons who have difficult prosthetic dental conditions can be significantly aided by newer orthognathic surgical procedures. The combined surgical-prosthetic approach for these patients requires close cooperation and communication between the general dentist or prosthodontist and the oral surgeon, particularly because various aspects of the surgical treatment planning for these patients differ greatly from those for patients with complete natural dentitions. A discussion and report of cases illustrate germane aspects of evaluation of conditions, treatment planning, and surgical approaches to the more commonly encountered surgical-prosthetic dental problems.- - - - - - - - - - ranking = 1034.6059263229keywords = dentofacial (Clic here for more details about this article) |
9/18. anophthalmos and first branchial arch defects.The association of unilateral mandibulofacial dysostosis and anophthalmos at the same side is reported. The proband presented at the age of six months with: right anophthalmos and hypoplasia of the orbit at the same side, hypoplasia of the right mandible and maxilla, right external ear deformity, cyanotic heart disease, hemivertebrae, cataract and corneal opacity in the left eye. This case shows the maximal effect of the abnormal development of the first branchial arch (the mandible, maxilla, and ears) on the globe and the orbit. The other end of the spectrum in which the minimal effect on the globe was present (unilateral absence of choriocapillaris and retinal pigment epithelium inferiorly) was reported by Cotlier & Alghadyan in 1981. This supports the concept that abnormal development of the mandible may influence the development of the orbit and the globe. The extent of the influence of the abnormal developing first branchial arch on the eye is discussed.- - - - - - - - - - ranking = 1keywords = deformity (Clic here for more details about this article) |
10/18. infection following intraoral surgical correction of dentofacial deformities: a review of 140 consecutive cases.Prophylactic antibiotics are often administered during orthognathic surgery to prevent infection. A total of 140 consecutive patients who underwent "clean" intraoral maxillary and mandibular orthognathic surgery and received antibiotics in the preoperative period are reviewed with respect to postoperative infection. In four patients, infections developed, two of which were related to alloplastic implants. The microorganisms cultured from the infections were species not normally found in oral infections. One patient had an antibiotic-induced anaphylactic reaction. The theory and applicability of antibiotic prophylaxis for intraoral orthognathic surgery are discussed.- - - - - - - - - - ranking = 1034.6059263229keywords = dentofacial (Clic here for more details about this article) |
