Asymmetry in the face and dentition is a naturally occurring phenomenon. Functional asymmetry can result the mandible being deflected laterally if occlusal interferences prevent proper intercuspation in centric relation. Five year old girl was referred to the pediatric department for mandibular deviation. The patient had right posterior crossbite and 2.5mm midline deviation due to dental caries on the primary teeth. The authors used the activator as occlusal splint for eliminating habitual posturing and deprogramming the musculature in the treatment of functional asymmetry and for occlusal stabilization restored the primary molars with cast crowns.

Backgrounds: MEG can measure the task-specific neurophysiologic activity with good spatial and time resolution. Language lateralization using noninvasive method has been a subject of interest in resective brain surgery. We purposed to develop a paradigm for language lateralization using MEG and validate its feasibility. Methods: Magnetic fields were obtained in 12 neurosurgical candidates and one volunteer for language tasks, with a 306 channel whole head MEG. Language tasks were word listening, reading and picture naming. We tested two word listening paradigms: semantic decision of meaning of abstract nouns, and recognition of repeated words. The subjects were instructed to silently name or read, and respond with pushing button or not. We decided language dominance according to the number of acceptable equivalent current dipoles (ECD) modeled by sequential single dipole, and the mean magnetic field strength by root mean square value, in each hemisphere. We collected clinical data including Wada test. Results: Magnetic fields evoked by word listening were generally distributed in bilateral temporoparietal areas with variable hemispheric dominance. Language tasks using visual stimuli frequently evoked magnetic field in posterior midline area, which made laterality decision difficult. Response during task resulted in more artifacts and different results depending on responding hand. Laterality decision with mean magnetic field strength was more concordant with Wada than the method with ECD number of each hemisphere. Conclusions: Word listening task without hand response is the most feasible paradigm for language lateralization using MEG. Mean magnetic field strength in each hemisphere is a proper index for hemispheric dominance.

Twin Blocks are simple bite-blocks that effectively modify the occlusal inclined plane to induce favorably directed occlusal forces by causing a functional mandibular displacement. These devices use upper and lower bite-blocks that engage on occlusal inclined planes. Twin Blocks use the forces of occlusion as the functional mechanism to correct the malocclusion. To get an excellent result in the treatment by using the Twin Block appliances, proper case selection must be needed. Twin Block treatment is performed in two stages. Twin Blocks are used in the active phase to correct the anteroposterior relationship and establish the correct vertical dimension. Once this phase is accomplished, the Twin Blocks are replaced with an upper Hawley type of appliance with an anterior inclined plane, which is then used to support the corrected position as the posterior teeth settle fully into occlusion. The Twin Block is the most comfortable, the most esthetic ane the most efficient of all the functional appliances. Twin Blocks have many advantages compared to other functional appliances. Patients can wear Twin Blocks 24 hours per day and can eat comfortably with the appliances in place. From the moment Twin Blocks are fitted, the appearance is noticeably improved. There is less interference with normal function. Integration with conventional fixed appliances is simpler than with any other functional appliance. Twin Blocks allow independent control of upper and lower arch width. Appliance design is easily modified for transverse and sigittal arch development. The authors treated Class II malocclusion with Twin Blocks. and the results as follows; 1. Rapid profile improvement was achieved in 2-3 months. 2. There was excellent patient cooperation. 3. Severe overjet and overbite were reduced. 4. Class II molar relationship was changed to Class I.

Objectives : The purpose of this study was to evaluate the chewing ability, oral-health related quality of life and factors in periodontal disease patients. Methods : Subjects were 111 patients having peridontal disease in 10 dental clinics in Busan and Gyeongsangnamdo. Questionnaire survey was carried out from July to August 2010. Questionnaire consisted of demographic characteristics, oral health factors, chewing ability and quality of life. Data were analyzed by descriptive analysis, t-test, ANOVA, correlation analysis, and multiple regression analysis using SAS(Ver 9.2) set at p<0.05. Results : Chewing ability was $44.85{\pm}8.8$, and their quality of life was $41.7{\pm}8.8$. Low level of quality of life was closely related to those factors as education, missing of more than 5 posterior teeth, certain subjective periodontal symptoms including swollen gums, sore gums, drifting gums, bad breath and toothache. The effective factors to the quality of life was chewing ability, bad breath and toothache. Conclusions : Chewing ability and quality of life were closely related each other. To enhance the quality of life, chewing ability should be improved. Proper treatment and effective method of management should also be properly considered to prevent the subjective periodontal symptoms and to minimize tooth loss.

Purpose: Multiple symmetric lipomatosis (MSL) is a relatively rare disorder characterized by presence of multiple, symmetric, nonencapsulated fat masses in face, neck, shoulder and other areas. There has been only a few cases reported in Korea. The main purpose of this research is to examine the Korean patients to see what kinds of special characteristics occurred due to this disease and to decide the proper treatment.Methods: A total of 16 patients were evaluated retrospectively. 5 patients were treated at our hospital. The other patients were reviewed from literature. We analyzed the biological characters of patients, location of fat deposit, morphologic characters of patients, clinical evidence of neuropathy, associated metabolic disorders and treatment modality.Results: All cases were male patient. The mean age of onset was 47.43 years. All patients were moderate to heavy alcoholics. The most common location of fat deposition was posterior neck and abdomen. In neurologic exam of 9 patients, 5 patients showed muscle weakness, tremor, pain and autonomic nerve dysfunction. In metabolic studies of 9 patients, total cholesterol values were higher in 1 patient. A glucose tolerance test was abnormal in 1 patient. In treatment modality, 14 patients were treated with surgical resection, 1 patient was treated with liposuction and surgical excision, 1 patient was treated only with liposuction. Conclusion: To treat MSL patients successfully, we should concentrate not only on the removal of the fatty tissue but also on neurologic abnormities, metabolic disorders and associated diseases.

Replantation using microvascular anastomosis is considered to be the optimal method in treating the amputated ear in terms of resulting color, texture, and shape. Only a few cases of ear replantation have been reported because it is anatomically difficult to identify suitable vessels for anastomosis. We successfully replanted the amputated helical rim of the ear using single arterial anastomosis. A 37-year-old man had his helical rim amputated by a human bite. The amputee was about $4{\times}1cm$ in dimension, composed of skin and soft tissue including auricular cartilage. Replantation was performed anastomosing a small artery of the amputee with a terminal branch of the posterior auricular artery. After replantation, intravenous heparinization was performed and prostaglandin E1 and aspirin were administered. Venous congestion was decompressed by stab incisions applied with heparin solution soaked gauze. Venous congestion of the amputee slowly began to resolve at 4 days after the operation. The amputated segment of the helical rim survived completely with good aesthetic shape and color. The authors propose that performing microvascular anastomosis should be attempted especially if it is possible to detect vessels on cut surfaces of ear amputee and stump. Proper postoperative care for venous congestion, arterial insufficiency, and infection should be followed for amputee survival.

Combining different procedures to reduce the number of surgical sessions and patient discomfort in implant placement and sinus floor elevation has been recommended, and evidence supports good outcomes. The aim of this study was to review the results of clinical studies on sinus floor elevation through extraction sockets and simultaneous immediate posterior implant placement. An electronic search was carried out in PubMed, Scopus, and Web of Science to find English articles published in or before August 2020. A manual search was also performed. Titles, abstracts, and the full-text of the retrieved articles were studied. Thirteen studies met our eligibility criteria: 6 retrospective case series, 3 case reports, 2 prospective cohort case-series, 1 prospective case series, and 1 randomized controlled trial. Overall, 306 implants were placed; 2 studies reported implant survival rates of 91.7% and 98.57%. The others either did not report the survival rate or reported 100% survival. Sinus floor elevation through a fresh extraction socket and simultaneous immediate implant placement appears to be a predictable modality with a high success rate. However, proper case selection and the expertise of the clinician play fundamental roles in the success of such complex procedures.

The bite collapses due to posterior teeth loss or wear results in inadequate space for restoration and esthetic concerns. Increasing the occlusal vertical dimension to improve space deficiency rotates the mandible posteriorly, creating a gap between the maxillary and mandibular anterior teeth, leading to loss of anterior guidance. To solve this problem, the prosthodontics or orthodontics treatments are the commonly used methods for proper anterior guidance. However, it is reasonable to assume that the anterior teeth can naturally relapse to their original position when the occlusal force is eliminated. Therefore, this case report aimed to test whether natural relapse could recover the lost anterior guidance to develop a less invasive and more convenient treatment method. Digital superimposition was used to evaluate the changes in anterior teeth alignment to confirm the change of the recovered anterior guidance. The appropriate indications for this new treatment method were defined and applied clinically.

'Transference phenomenon' is considered as a essential feature in psychotherapy as well as psychoanalysis. But there is much difference in conceptual and methodological issues for 'transference phenomenon' among various psychoanalytical schools. In general, the depth psychological studies for 'transference phenomenon' are mainly from the psychoanalytical view of point but relatively sparse from the analytical psychological view of point which has more holistic and deeper understanding for human psyche. So this article was intended for a comprehensive review of 'transference phenomenon' from the perspective of analytical psychology and tried to make an understanding for its meaning. To begin with, the concept of 'transference phenomenon' was investigated from the view before Jung and after Jung, with Jung's view in the center. Then it was made clear that 'transference phenomenon' from the perspective of analytical psychology could be understood by several characteristic aspects. It was suggested that a careful study on the symbolic meaning of the woodcuts' pictures in Rosarium Philosophorum including a proper interpretation of its posterior part to which Jung didn't refer in "The Psychology of The Transference" be devoted to the genuine understanding of 'transference phenomenon' from the perspective of analytical psychology afterwards.

Background: Ankle sprains are a common clinical ankle disorder and alternations in tibiofibular joint biomechanics along with the talus are thought to contribute to its occurrence. During ankle joint dorsi flexion, proper movement requires the talus to glide posteriorly. Due to the wider front of the talus head, achieving the end range of dorsi flexion necessitates both superior and posterior glide of the distal fibula and anterior glide of the proximal fibula. The purpose of this study was to investigate the effects of tibiofibular joint mobilization on pain, range of motion, and balance in patients with lateral ankle sprains. Methods: Participants were randomly assigned to a control group (n=33) or an experimental group (n=31). Both groups underwent ankle joint mobilization three times a week for two weeks. Additionally, the experimental group received proximal and distal tibiofibular joint mobilization three times a week for two weeks. Measurements were obtained pre-intervention and post-intervention (after 2 weeks). Results: Evaluation parameters included the visual analog scale score (VAS), range of motion (ROM), and one-leg standing test (OLS). Post-intervention, both groups demonstrated significantly improved results for all assessments (p<.01). A significant intergroup difference was observed only in the ROM (p<.01) and OLS (p<.05). Conclusion: Our findings suggest that tibiofibular joint mobilization, combined with ankle joint mobilization, may be beneficial in enhancing outcomes for individuals with lateral ankle sprains.
