The common errors in preoperative treatment plan for the orthognathic surgery can be occurred during cast impression, cast mounting procedure with face-bow transfer, surgical stent fabrication, and so on. One of the most common errors exists during mounting process of the model on the articulator. Accurate mounting of dental casts to articulator should be achieved by transferring the 3-dimensional spatial relationship of the maxillary arch to an articulator. A face-bow is used for transfer this relationship to articulator, usually by relating the face-bow to a plane of reference of maxillary cast. The purpose of this study is evaluation of the accuracy of face-bow transferring of maxillary model to the articulator. The maxillary casts of thirty patients for orthognathic surgery were mounted on articulator with an face-bow instrument. The relationship of occlusal plane angle to Frankfort horizontal plane relations were compared the cephalogram with the cast-mounted articulator. As a result of this study, the significant difference between the maxillary occlusal planes angle in the cephalogram and articulator were found . The results were followed, 1. The mean occlusal plane angle in cast-mounted articulator was 13.5􀆆(SD±5.4). 2. The mean occlusal plane angle in cephalogram was 10.4􀆆(SD±4.3). 3. The mean difference of occlusal plane angle between cast-mounted articulator and cephalogram was 3.3􀆆(SD±4.6). According to the result, we should suggest that the occlusal plane angle to Frankfort plane in cast-mounted articulator is more steeper than that of cephalogram. And then, maxillofacial surgeon should try to get a more predictable result by suggesting the proper correction method and mounting the cast accurately.

Objectives This study aimed to evaluate the effects of atopic care program through observing atopic patients who have lived in atopic-free village located Geumsan of Chungnam province. Methods Seventeen children (boy 7, and girl 10) with atopic dermatitis had moved into atopic-free village of Geumsan, and they have been cared with atopic care program. Atopic dermatitis symptoms were measured every month using SCORAD (Scoring of Atopic Dermatitis) and EASI (Eczema Area and Severity Index) from March, 2012 to September, 2013. The changes of scores were analyzed using paired t-test. Results The median month of residence period was 19.9 months (range from 6 to 42 months). The atopic symptoms were significantly improved on SCORAD (p<0.01) and EASI (p<0.1) respectively. Conclusion Despite the limitation of the small number of study subjects, this study may provide the possibility of natural environment-based therapy for children with atopic dermatitis.

Acinic cell carcinoma is a rare salivary gland carcinoma, usually being found in the parotid gland and is uncommon in the other major and minor salivary glands. The tumor cells consist of either serous or mucous acinar cells with few ductal or myoepithelial cell elements. The tumor is a low-grade malignancy with slow growth potential. Surgical therapy depends on tumor size and the extent of infiltration into neighboring tissues. Superficial parotidectomy or total parotidectomy is the initial method of therapy in case of acinic cell carcinoma on parotid gland. When regional neck lymph nodes are involved, the operation is combined with a neck dissection, or with radiation therapy. In the short follow up period, acinic cell carcinoma has good prognosis with 5 year survival rate after surgery is over 80%. In the long-term follow-up, however, there is a tendency to increase in recurrence or metastasis. We experienced a case of acinic cell carcinoma of parotid gland in a 57-year-old female, so we report it with literatures review.

False aneurysms(Pseudoaneurysms) and arteriovenous fistulas have only rarely been reported in the facial region. In this region the false aneurysm arises most frequently in the superficial temporal and facial artery, but other branches of the external carotid are sometimes involved, including the maxillary and lingual artery. False aneurysms can be occurred by blunt trauma that either laceration or rupture the full thickness of the arterial wall. The diagnosis of a false arterial aneurysm can be often made solely on the basis of physical examination. Angiography is helpful for conformation, for delineating the lesion and its vascular supply, and for ruling out the presence of associated vascular lesions such as arteriovenous fistulas. Ultrasonography may also be useful in delineating lesions that are not easily accessible for physical examination. Treatment of false aneurysms is excision, ligation, and arterial embolization. This is a case of false aneurysm of the lingual artery after facial trauma caused by traffic accident. The lesion was successfully treated by embolization and ligation of the lingual and facial branches of the external carotid artery.

Primary intraosseous carcinoma(PIOC) is defined as a squamous cell carcinoma arising within the jaw, having no initial connection with the oral mucosa. The squamous cell carcinoma within the bone can be presumably developed from residues of the odontogenic epithelium, therefore, it is seen in the jaw only. Metastatic carcinoma from another primary site should be excluded in the diagnosis of Primary Intraosseous Carcinoma. This is a case of 62-year-old man, who initially diagnosed as odontogenic cyst on maxilla, but its pathologic examination was diagnosed as squamous cell carcinoma with odontogenic cyst. We treated this patient with partial maxillectomy, modified radical neck dissection(mRND), and postoperative radiation therapy.

The major disadvantage of cement-retained implant-supported superstructure is difficulty of retrievability. Sometimes, it is recommended that proetheses be provisionally cemented to implant abutment in order to ebaluate occlusion, screw loosening and tissue reaction. The retention of the provisional luting cementedusually employed in this case is considered to be important. This study compared tensile bond strength of gold crowns cemented to machined titanium implant abutments with three provisional luting cements. Also the effect of petrolatum and thermocycling on tensile bond stength were evaluated. Tensile bond strength of provisional luting cement were as follows with the decreasing order of Eugenol (13.06±1.544 kgf), Temp-Bond (9.41±0.737 kgf), Cavex (8.04±0.974 kgf), and Temp-bond with petrolatum (5.28±0.800 kgf). The addition of petrolatum in Temp-bond decreased tensile bond strength significantly (p<0.01). After thermocycling of 1,500 cycles, the tensile bond strengths of the cements were decreased with the order of Nogenol (10.87±3.031 kgf), Temp-Bond (8.1±0.667 kgf), Cavex (7.33±1.103 kgf), Temp-bond with petrolatum (4.88±1.348 kgf). The mocycling decreased the bond strength of Temp-Bond significantly, with no effects no other cements (p<0.01).
