Résumé

INTRODUCTION: This study examined the anatomical morphology of the medial surface of the posterior mandible using 3-dimensional cone-beam computed tomography (CT) images to reduce the number of complications related to dental implant placement. MATERIALS AND METHODS: Fifty patients were enrolled in this study with an average age (+/-standard deviation) of 44.28 (+/-13.05). On the coronal views cone-beam CT of the first molars, the distance between the top of the canal and alveolar crest vertical distance (VD), the distance between the upper-most point of the canal and the point perpendicular to the lingual cortical margin of the mandible lingual distance (LD), the location of the starting point of VD for reducing from the vertical reference line (VD point), and the inclination of the mandibular medial surface (lingual inclination) were measured, and a statistical evaluation was performed using SPSS for Windows version 15.0. RESULTS: The mean VD0 was 16.91+/-2.47 mm and VDx decreased with increasing x value. The mean LD was 5.27+/-1.36 mm. The VD began to decrease at the mean location of 6.12+/-0.96 mm from the vertical reference line. The mean lingual inclination was 1.52+/-0.72degrees. CONCLUSION: These results will assist in the accurate placement of dental implants and the reduction of complications, particularly in the case of preoperative implant planning using only 2-dimensional imaging methods.

Résumé

PURPOSE: The objective of this study was to evaluate the efficacy of the subperiosteal tunneling technique with iliac block bone graft for bone augmentation in an edentulous alveolar ridge. PATIENTS AND METHODS: Total of 8 sites in 7 patients were included in this study. The bone height was evaluated by CBCT preoperatively and 4 months after operation. Total of 11 implants were inserted and evaluated clinically and radiographically. RESULTS: Mean value of the increased bone height was 6.29 mm and no implant failure was observed. There were no complications such as soft tissue dehiscence, exposure of the grafted bone and infection. CONCLUSION: We have achieved excellent clinical outcomes by this technique, so we concluded that it is useful for augmentation of severely deficient alveolar ridge.

Résumé

PURPOSE: To research about maxillofacial traumatic injuries of children in aspects of gender difference, various incidence rates between age, trauma type, cause, monthly and daily incidence rate, type of tooth damage, gingival damage, soft tissue damage, and type of facial bone fracture. MATERIALS AND METHODS: Study group consisted of children under 15 years of age who visited Dental Hospital, School of Dentistry, Kyung Hee University from 2004/7/1 to 2007/6/30 with chief complaint of oral and maxillofacial traumatic injuries. 1,559 cases of traumatic injuries were studied from 1,556 (1,004 male, 552 female) children. CONCLUSION: 1. There were slightly more boys than girls, giving a male-to-female ratio of 1.82:1.0. The 1-3 year old boys and girls had the highest number of traumatic injuries. 2. Of the 1,556 patients, 68.63% had soft tissue injuries, 50.22% had periodontal injuries, 29.89% had teeth injuries, and 3.85% had maxillofacial bone fractures. 3. Falling down was the most common cause of injury in both sexes. 4. The months with the highest incidence rates were in order May (12.12%), June (11.74%), and October (11.13%). Most of the injuries occurred on weekends. 5. The most common tooth injury was uncomplicated crown fracture, and the most common periodontal injury was subluxation. The majority of traumatizes teeth were the upper central incisors. 6. The most common soft tissue injury was intraoral lacerations. 7. Mandibular fractures were most frequent in facial bone fractures; symphysis, condylar head, and angle fractures were most frequent in mandibular fractures; maxillary and nasal bone fractures were most frequent in midfacial bone fractures.

Résumé

Mesenchymal chondrosarcoma is very aggressive and represents approximately 1% of all chondrosarcomas. While it affects a very wide age range, the peak frequency is in the second decade of life. It may occur in the head and rib region with a predilection for the maxillofacial skeleton. The small cell undifferentiated component may assume a hemangiopericytoma-like vascular pattern and should be distinguished from hemangiopericytoma. Treatment is en bloc resection, the intended tissue margins of excision should be designed to extend well beyond the actual tumor margin, as mesenchymal chondrosarcomas. Aggressive behavior of mesenchymal chondrosarcoma of the jaw, with a tendency for delayed recurrence and metastasis even many years after treatment. The most frequent site of metastasis was the lung. Here we present 52 years old , female case of mesenchymal chondrosarcoma occurs on Rt. mandible.

Résumé

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a side effect of Bisphosphonates (BPs) use. These days, oral bisphosphonates are normally prescribed to treat osteoporosis. Intravenous BPs are used extensively to treat osteolytic bone lesions related to multiplemyeloma and bone metastasis of solid cancers, breast cancer or prostate cancer. As the prescription of BPs is universalized and the number of people treated with BPs is increasing, an accurate understanding and proper management of BRONJ are required. The aim of this study was to improve the clinicians'understanding of BRONJ by reviewing the literature. To achieve this, this paper introduces case reports as well as the current concept of BRONJ based on the 2009 updates by American Association of Oral and Maxillofacial (AAOMS) including the definition, epidemiology, etiology, diagnosis, treatment and prevention of BRONJ.

Résumé

Cemento-osseous dysplasias are a group of disorders known to originate from periodontal ligament tissues and involve, essentially, the same pathological process. They are usually classified, depending on their extent and radiographic appearances, into three main groups. Periapical cemental dysplasia predominantly involves the periapical region of the anterior mandible. Florid cemento-osseous dysplasia presents with multifocal lesions in the tooth bearing or edentulous areas of the maxilla and mandible, often occurring bilaterally with symmetric involvement. Focal cemento-osseous dysplasia exhibits a single site of involvement in any tooth bearing or edentulous area of the mandible or maxilla, with the posterior mandible representing the most common site. We report the clinical, radiographic and histological findings of 3 types of cemento-osseous dysplasia with a review of literatures.

Résumé

Recently, an increasing number of bisphosphonate related osteonecrosis of the jaw(BRONJ) is being reported. A guideline has been already established in the US, but it does not seem to be fully recognized by clinicians in Korea. Therefore, a survey study was done to inform and have clinicians realize the seriousness of BRONJ. 1,341 practitioners were randomly selected out of 13,405 practitioners(by Feb of 2008, KDA) in Korea. A questionnaire was given to them between May to July in 2008. Questions were designed to investigate each respondent's experience term years in the clinic, occupation, speciality, awareness on risk of bisphosphonate, experience on treating osteonecrosis patients, awareness about the guideline on BRONJ suggested by AAOMS and whether if they ask about bisphosphonate medication history to patients before invasive treatment. 45.1% of the clinicians have reported on experiencing delayed healing on bone exposed site after extraction both in the maxilla and the mandible. However, clinicians have asked the patients whether if they are on bisphosphonate or not in only 15.1% of these cases. 56.5% of the clinicians simply knew about BRONJ but only 28.9% of the clinicians were aware that bisphosphonate can cause osteonecrosis after invasive dental treatment. Only 19.3% knew about the contents of guideline on BRONJ and 57.2% were aware of the seriousness of BRONJ. Clinicians with shorter clinical experience term were more aware of BRONJ and the guideline on BRONJ than the experienced clinicians. But awareness of the possibility of BRONJ after invasive dental treatment were about the same regardless of their clinical experience. The results show that Korean clinicians need to be more aware about BRONJ. Data on BRONJ cases in Korea should be collected and provided with additional education to let Korean clinicians know and be more aware about BRONJ
