1/14. Surgical simulation of Class III edentulous patient using a 3D craniofacial model: report of a case.A case of edentulous prognathism in a 46-year-old Japanese male is presented. We described the outcome of the patient who underwent simultaneous sagittal splitting ramus osteotomy of the edentulous mandible, interpositional bone graft of severely atrophic edentulous jaws, and delayed placement of titanium implants for reconstruction. We highly recommend performing a surgical simulation using a craniofacial model of the patient's anatomy created using CT image data. The procedure provides almost ideal maxillary and mandibular contours.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
2/14. Reduction of the hypocone of the maxillary first molar and Class III malocclusion.This study was conducted to examine the incidence of evolutionary changes of the maxillary molars in orthodontic patients and to investigate the association of this event with craniofacial growth. Among 4,892 Japanese patients treated at the orthodontic clinic of Hiroshima University Dental Hospital, 59 patients presented with a defect of the distolingual cusp of the maxillary first molar. They consisted of 52 female patients and seven male patients with a mean age of 14.7 years. Eruption of the maxillary first and second molars was delayed and the third molar was congenitally missing in all of these patients. Thirty-seven patients exhibited Class III malocclusion (Class III evolution group). The Z scores of cephalometric measurements were compared between the Class III evolution group and the Class III control group. The latter group consisted of 37 Class III subjects with no evolutionary dental anomalies and no orthodontic history. The tooth developmental score (TDS) for each age at the initial record was compared with Nolla's standard tooth developmental score (STDS) for equivalent ages using paired t-tests. The Z scores for Ptm'-A and Ar-A were significantly smaller in the Class III evolutionary group than in the Class III control group (P < .05). The TDS for the maxillary first and second molars were significantly smaller than the STDS for these molars (P < .01). The TDS for the maxillary second molar was significantly larger than the STDS for the maxillary third molar (P < .01). This study revealed that an evolution change of the maxillary molar is more common (P < .05) in female patients than in male patients, is more frequent (P < .05) in subjects with Class III malocclusion, and is related to the anteroposterior undergrowth of the maxilla.- - - - - - - - - - ranking = 0.2keywords = craniofacial (Clic here for more details about this article) |
3/14. Mandibular distraction in the absence of an ascending ramus and condyle.The introduction of distraction osteogenesis (DO) as a method of mandibular elongation has provided the craniofacial surgeon with a valuable tool in the approach to patients with mandibular deficiencies. A growing number of case reports and clinical series have proven the efficacy of mandibular DO as an augmentative technique in patients with hemifacial microsomia (HFM). Although DO has become a part of the treatment algorithm for many patients with HFM, surgeons have been reluctant to apply the technique in patients with complete agenesis of the ascending mandibular ramus and condyle (grade III HFM). In the following cases, mandibular DO was successfully performed in two patients with grade III HFM. Preoperative images and intraoperative findings confirmed that both patients lacked the entire ascending mandibular ramus and condyle on the affected side. After unilateral multiplanar DO, both patients showed new bone formation within the distraction gap and development of a pseudoarthrosis between the proximal segment of the mandible and the skull base. Facial symmetry improved dramatically, and speech and mandibular excursion were maintained. The patients have been followed for 1 to 2 years after distraction with durable functional and esthetic outcomes. Mandibular DO offers many advantages compared with rib grafting, including avoidance of donor site morbidity, application in patients who are not candidates for graft harvest, and use after rib graft failure. The following cases support the use of mandibular DO as a mechanism of endogenous tissue engineering in patients with complete agenesis of the ascending mandibular ramus and condyle.- - - - - - - - - - ranking = 0.2keywords = craniofacial (Clic here for more details about this article) |
4/14. Early treatment of skeletal Class III: a case report.Skeletal class III malocclusion is a growth related facial deformity which increases if left untreated. Skeletal class III malocclusion should be corrected as soon one recognises the initial signs. Mixed dentition period is the time of greatest opportunity for occlusal guidance and growth modulation. A case of skeletal class III malocclusion in mixed dentition is presented, which was treated with a Delaire face mask therapy to modulate the craniofacial growth and to achieve a balanced profile.- - - - - - - - - - ranking = 0.2keywords = craniofacial (Clic here for more details about this article) |
5/14. hajdu-cheney syndrome (acro-osteolysis): a case report of dental interest.hajdu-cheney syndrome (acro-osteolysis) is a rare disorder of bone metabolism characterized by progressive lytic lesions in a number of bones. Constant features of this condition include an osteoporotic skeleton, acro-osteolysis, and a shortened lower third of face. The purpose of this report was to focus on the craniofacial and oral manifestations of the disorder in a 9-year-old boy.- - - - - - - - - - ranking = 0.2keywords = craniofacial (Clic here for more details about this article) |

7/14. Orthodontic treatment with growth hormone therapy in a girl of short stature.The purpose of this article is to review the characteristics of craniofacial morphology in children of short stature and the effects of human growth hormone (HGH) therapy on the craniofacial complex. Changes in body height, facial growth, and dental maturity of a 9-year-old girl who received HGH therapy during orthodontic treatment were observed. Orthodontists need to understand the skeletal characteristics of the craniofacial complex of short-stature patients before beginning orthodontic treatment and consider how the differences between chronologic and skeletal ages affect the timing and method of orthodontic treatment. If short-stature children are undergoing HGH therapy, its cranioskeletal effect should be considered; if possible, it is better to delay orthodontic treatment until HGH is finished. However, if orthodontic treatment is performed, the following should be considered: (1) HGH therapy affects the growth of the mandible more than the growth of the maxilla, (2) the amount and pattern of growth during HGH administration are unpredictable, and (3) HGH therapy rarely affects dental maturity.- - - - - - - - - - ranking = 0.6keywords = craniofacial (Clic here for more details about this article) |
8/14. Prevention of halo pin complications in post-cranioplasty patients.INTRODUCTION: Distraction osteogenesis has been successfully implemented in the treatment of maxillary hypoplasia. By using the Rigid External Distraction device (RED) the maxilla can be advanced without the need for bone grafts, providing more stability to the repositioned maxilla. BACKGROUND: The introduction of the RED system in craniofacial surgery has given rise to previously unseen problems. AIM: To provide a set of protocol improvements that might prevent the intracranial pin migration seen at the removal of a RED-II in one patient. CONCLUSIONS: Although the RED device has been shown to achieve good clinical results, there are some disadvantages to the system. There is a high incidence of pin tract infections - leading to loosening of the pins and loss of rigidity. Also, the external ring is prone to traumatic injury. Furthermore, the positioning of the pins can be difficult in thin bone. The improvements used in our protocol might prevent this complication.- - - - - - - - - - ranking = 0.2keywords = craniofacial (Clic here for more details about this article) |
9/14. Dentomaxillofacial imaging in proteus syndrome.proteus syndrome is a rare condition that involves atypical growth of the bones, skin and head and a variety of other symptoms. Only a few authors have reported on the craniofacial manifestations so far. The authors present a case of a 7-year-old girl with proteus syndrome in which the facial skeleton showed unilateral overgrowth. The analysis of the radiological evaluation revealed a bialveolar prognathism, a skeletal class III, a dolicocephalic growth pattern and a left convex face scoliosis. On the left side, the lesser wing of the sphenoid was elevated and the ethmoidal cell complex was hypertrophic. The left ramus and body of the mandible were enlarged. The asymmetric dental development with a precocious dental age on the affected side was the most striking feature on the panoramic view. early diagnosis and therapy depend on clinical evaluation and imaging. Therefore, further evaluations on the craniofacial features of patients with proteus syndrome are necessary in order to establish a list of characteristic symptoms.- - - - - - - - - - ranking = 0.4keywords = craniofacial (Clic here for more details about this article) |
10/14. orthognathic surgery for a patient with trichorhinophalangeal syndrome type I: a case report.Trichorhinophalangeal syndrome (TRPS) type I is characterized by slowly progressing systemic osseous dysplasia, exhibiting craniofacial and other skeletal deformities. However, there have been few reports describing this syndrome after undergoing orthognathic surgery. In this report, we present a patient with TRPS I who successfully underwent orthognathic surgery. In addition, we examined the skeletal stability of the patient for 2 years after the surgery.- - - - - - - - - - ranking = 0.2keywords = craniofacial (Clic here for more details about this article) |
