  • Background: The purpose of this study was to compared of scapular position between operation side and non-operation side to the rotator cuff surgery. Methods: This study was carried out with a total 34 patients: male (n=14), female (n=20). Shoulder range of motion (ROM), the quadruple visual analogue scale (QVAS), the shoulder pain and disability index (SPADI), and the scapular index (SI) were used to assess shoulder posture and function. SI was the resting position of the scapular was determined by measuring the distance from the mid-point of the sternal notch (SN) to the medial aspect of the coracoid process (CP) and the horizontal distance from the posterolateral angle of the acromion (PLA) to the thoracic spine (TS) with a soft tape measure. The SI was calculated using the equation: [(SN to CP/PLA to TS) ${\times}$ 100]. Results: There were no significant difference in ROM, QVAS to rotator repair patients according to SI (p>.05). There were significant differences in SI between the operation side and the non-operation side (p<.01). Conclusions: Scapular position was operation side more internal rotation, protraction, abduction than non-operation side. Therefore, health professionals managing for rotator cuff tear repair patients should consider scapular position.

  • Purpose: The purpose of this study was to compare a control group and an experimental group, consisting of arthroscopic shoulder surgery patients who had received acute rehabilitation treatment and who were to perform scapular stabilization exercise. Methods: Sixteen subjects were studied. The control group, n=8, received instruction for basic physical therapy intervention. An experimental group, n=8, received instruction for doing scapular stabilization exercise (protraction, retraction, elevation, depression) 10 times, 6 times per week. To evaluate the effects of exercise, subjects were evaluated using a joint position sense of shoulder (JPS), disability of the arm, shoulder index (DASH), shoulder pain and disability index (SPADI). Results: Participants showed after the intervention, both groups saw their JPS errors at $30^{\circ}$, $60^{\circ}$, and $90^{\circ}$ significantly decrease relative to before the intervention (p<0.05). Both groups saw their JPS rates at $90^{\circ}$ significantly decrease (p<0.05), with no significant changes in JPS at $30^{\circ}$ and $60^{\circ}$ (p>0.05). SPADI and DASH significantly decrease after the intervention (p<0.05), with no significant decreases before the intervention (p>0.05). The change rates of SPADI and DASH significantly reduced (p<0.05). Conclusion: Low-intensity scapular stabilization exercise is considered effective as a clinical treatment for arthroscopic shoulder surgery patients who receive acute rehabilitation treatment.

  • In this report, we describe the successful use of alternate rapid maxillary expansions and constrictions with a hybrid hyrax-mandibular miniplate combination and simultaneous orthodontic treatment for the management of severe Class III malocclusion due to maxillary hypoplasia in an 11-year-old girl. The devices were removed after 20 months of treatment, and the family was instructed about a careful control and retention program that should be followed in accordance with the patient's growth. The final result included the correction of Class III malocclusion with adequate function and excellent facial esthetics, which restored the patient's self-esteem and provided personal motivation. The outcomes showed good stability after 24 months of retention. The decrease in the duration of active treatment is the most important finding from the present case. Considering that facial esthetics in adolescence is a determining factor for the development of a personality and interpersonal relationships, we recommend the use of this protocol for growing patients, who will exhibit not only an improved physical appearance but also a better quality of life.

  • PURPOSE: The purpose of present study was to ascertain how the activity of the serratus anterior muscle, the upper trapezius muscle and the pectoral major muscle was affected while the upper arm was being flexed at 70, 90 and 110 degrees respectively in a closed kinetic chain exercise (wall push up plus) and an open kinetic chain exercise (static hug). METHODS: Sixteen healthy young men subjects participated in the study. Surface electromyography (EMG) data were collected from the dominant-side muscles during a closed kinetic chain exercise and an open kinetic chain exercise. The activity of each muscle was measured quantitatively, and by the use of the two-way repeated ANOVA, the data were compared with each other according to exercises and shoulder flexion angles. RESULTS: Results indicated that the closed kinetic chain exercise did not interact with the open kinetic chain exercise (p>.05). In both the closed kinetic chain exercise and the open kinetic chain exercise, the activity of the serratus anterior muscle became different significantly according to angles (p<.05). Its activity increased in order of 70, 90 and 110 degrees (p<.05). In both exercises and all angles, muscle activity was significantly higher in the serratus anterior muscle than in the upper trapezius muscle and the pectoral major muscle (p<.05). CONCLUSION: The above results show that there is a need to selectively control the exercise stress of the serratus anterior muscle in the case of the patients with the shoulder impingement syndrome characterized by the winged scapula, insufficient scapular protraction and upward rotation.

  • The purpose of orthodontic treatment is to produce functional occlusion and to create or maintain facial esthetic harmony. The soft-tissue covering of the face also plays an important role in facial esthetics, speech and other physiologic functions. The study of the soft-tissue profile is important for the planning of orthodontic treatment. The author studied cephalometric X-ray films on 49 patients (23boys, 26 girls) with Angle's class II division 1 malocclusion, ranged from 9 to 13 years of age. Roentgenocephalmetric X-ray films were taken pre and post orthodontic care. Tracings were made in usual manner. The obtained results were as follow. 1. There was no significant sexual difference on mean changes. 2. In the comparison of the soft-tissue thickness changes, Ls-Ls' and Si-Si' in male subjects were remarkable. 9. There were significant correlations between osseous (Ss') change and soft-tissue (Ss) chang, of maxilla in male and female subjects subsequent to orthodontic treatment. 4. The ratios between the protraction of the Ss' and that of the Ss were 1:1.5 in all sexes, the ratios between the Si' and that of the Si were 1:1.4 in male and 1:1.2 in female. 5. There were significant correlations between maxillary central incise. angulation change $({\angle}A)$ and upper lip inclination change $({\angle}B)$ in all sexes. 6. There were little correlations between change in distance difference of Is and Ii and change in distance difference of Ls and Li in all sexes in all sexes.

  • The purpose of this study was to compare and evaluate facemask effects when two types of intraoral appliances were used for maxillary protraction for patients with class III malocclusion. Eighteen patients with class III malocclusion were treated with a facemask for an average of 12 months. Two types of intraoral appliances were used: nine patients were treated with bonded expander (Group 1), and nine patients with Hyrax (Group 2). Cephalometric radiographs were taken before and after treatment. Cephalometric radiographs were traced, analyzed, and the results such as sagittal, vertical and soft-tissue changes were compared between two groups. The amount of anchorage loss was also measured to evaluate the difference between two groups. All patients showed significant sagittal skeletal changes after treatment, and there was no statistically significant difference between the two groups. When anchorage loss was evaluated, no differences were shown between the two. Facemask with Hyrax or bonded expander is similarly an effective method as a treatment in class III malocclusion patients.

  • A General survey on the cleft lip and/or palate patients in Pusan National University Hospital was done. The conclusions were as follow. 1. In gender ratio, male was higher than female. 2. In the cleft type, unilateral cleft lip and palate, cleft lip and alveolus, and bilateral cleft lip and palate in higher ratio order. Left unilateral cleft lip and palate was higher than right in ratio. 3. In first hospital visiting age for dental treatment, the group from 6 years old to 12 years old was most and in that the age group for attending elementary school (about 7-8 years old) showed especially higher ratio. The large majority of patient were born in 1980's and lived in Pusan metropolitan city, KyungSangNamDo. Especially, most of them lived in the neighboring Held of Pusan National University Hospital. 4. Class III skeletal pattern and Angle's Class III molar relationship was most prevalent. Angle's Class II molar relationship showed relative higher ratio because tooth loss and malposition. 5. Primary lip closure in 3 months, secondary lip closure in 6-7 years old, palatal closure in 12-16 months and bone graft in 8-10 years old were operated mostly. Rhinoplasty and scar revision were operated in too early age so the need of infantile orthopedics must be considered. 6. Maxillary expansion and protraction were operated mostly in 8-11 years old but operating in primary dentition must be considered. 7. Tooth alignment were started mostly in mixed dentition and consideration about prosthodontic treatment and retention will be need. 8. In tooth anomaly, tooth malformation and missing were most prevalent.

  • Objective: A national survey was conducted to assess orthodontic residents' current concepts and knowledge of cleft lip and palate (CLP) management in Korea. Methods: A questionnaire consisting of 7 categories and 36 question items was distributed to 16 senior chief residents of orthodontic department at 11 dental university hospitals and 5 medical university hospitals in Korea. All respondents completed the questionnaires and returned them. Results: All of the respondents reported that they belonged to an interdisciplinary team. Nineteen percent indicated that they use presurgical infant orthopedic (PSIO) appliances. The percentage of respondents who reported they were 'unsure' about the methods about for cleft repair operation method was relatively high. Eighty-six percent reported that the orthodontic treatment was started at the deciduous or mixed dentition. Various answers were given regarding the amount of maxillary expansion for alveolar bone graft and the estimates of spontaneous or forced eruption of the upper canine. Sixty-seven percent reported use of a rapid maxillary expansion appliance as an anchorage device for maxillary protraction with a facemask. There was consensus among respondents regarding daily wearing time, duration of treatment, and amount of orthopedic force. Various estimates were given for the relapse percentage after maxillary advancement distraction osteogenesis (MADO). Most respondents did not have sufficient experience with MADO. Conclusions: These findings suggest that education about the concepts and methods of PSIO and surgical repair, consensus regarding orthodontic management protocols, and additional MADO experience are needed in order to improve the quality of CLP management in Korean orthodontic residents.

  • Objective: Esthetic improvements during orthodontic treatment are achieved by changes in positions of the lips and surrounding soft tissues. Facial soft-tissue movement has already been two-dimensionally evaluated by cephalometry. In this study, we aimed to three-dimensionally assess positional changes of the adult upper lip according to simulated maxillary anterior tooth movements by white light scanning. Methods: We measured changes in three-dimensional coordinates of labial landmarks in relation to maxillary incisor movements of normal adults simulated with films of varying thickness by using a white light scanner. Results: With increasing protraction, the upper lip moved forward and significantly upward. Labial movement was limited by the surrounding soft tissues. The extent of movement above the vermilion border was slightly less than half that of the teeth, showing strong correlation. Most changes were concentrated in the depression above the upper vermilion border. Labial movement toward the nose was reduced significantly. Conclusions: After adequately controlling several variables and using white light scanning with high reproducibility and accuracy, the coefficient of determination showed moderate values (0.40-0.77) and significant changes could be determined. This method would be useful to predict soft-tissue positional changes according to tooth movements.

  • The purpose of this case report was to introduce the concept of orthodontic and orthopedic treatment for a growing patient with Tessier number 0 cleft. A 5-year-old boy patient with Tessier number 0 cleft presented congenitally missing maxillary central incisors (MXCI), a bony defect at the premaxilla, a constricted maxillary arch, an anterior openbite, and maxillary hypoplasia. His treatment was divided into three stages: management of the bony defect at the premaxilla and the congenitally missing MXCIs using a fan-type expansion plate, iliac bone grafting, and eruption guidance of the maxillary lateral incisors into the graft area for substitution of MXCIs; management of the maxillary hypoplasia using sequential facemask therapy with conventional and skeletal anchorage; and management of the remaining occlusal problems using fixed orthodontic treatment. The total treatment duration was 15 years and 10 months. Class I canine and Class II molar relationships and normal overbite and overjet were achieved at the end of treatment. Although the long-term use of facemask therapy resulted in significant protraction of the retrusive maxilla, the patient exhibited Class III profile because of continued mandibular growth. However, the treatment result was well maintained after 2 years of retention. The findings from this case suggest that interdisciplinary and customized approaches are mandatory for successful management of maxillary hypoplasia, bony defect, and dental problems in Tessier number 0 cleft. Moreover, considering the potential of orthognathic surgery or distraction osteogenesis, meticulous monitoring of mandibular growth until growth completion is important.
