In case of gingival recession or bone defect in maxillary anterior implant treatment, it is not easy to obtain satisfactory clinical results. In this case, loss of the labial alveolar plate was diagnosed in the maxillary right central incisor, so after tooth extraction, soft tissue was secured and implant placement with bone graft was planned. In addition, digital guide surgery was performed for the ideal implant position, and GBR (Guided Bone Regeneration) was accompanied with the xenogeneic bone and the autologous bone collected from the mandibular ramus since alveolar bone defects were extensive. After a sufficient period of osseointegration of the implant, a temporary prosthesis was fabricated through secondary stage surgery and impression taking, and through periodic external adjustment, the shape of soft tissue was improved. In the final prosthesis fabrication, a color tone of natural teeth was induced by an gold anodized customized abutment, and an aesthetic and functional zirconia prosthesis with reproducing the shape of the temporary prosthesis through intraoral scan was delivered.

Background: Postoperative recurrence is a major problem after performing video-assisted thoracic surgery for the treatment of primary pneumothorax. This study was designed to evaluate the efficacy and safety of a bioabsorbable staple line reinforcement (GORE $SEAMGUARD^{(R)}$) for preventing recurrence after bullectomy. Material and Method: From January 2000 to December 2004, 300 patients underwent video assisted thoracoscopic surgery for the treatment of primary penumothorax. 143 patients were treated with bioabsorbable staple line reinforcement (Group A) and 142 patients were treated with stapling of the bullae (Group B). Mechanical pleural abrasion was performed in all the patients. The operating time, the duration of the indwelling chest tube, the length of the hospital stay and the number of recurrences after operation were compared between the groups. Result: No operative deaths occurred. The conversion rate to an open procedure was 5% (15/300). Comparison with these groups (Group A versus Group B) showed the following results: the operating time ($49.6{\pm}25.6$ vs $51.8{\pm}30.4$ minutes, respectively, p=0.514), the duration of an indwelling chest tube ($5.8{\pm}2.5$ vs $7.2{\pm}3.3$ days, respectively, p<0.005), the hospital stay ($10.9{\pm}4.3$ vs $12.5{\pm}4.3$ days, respectively, p<0.005) and the number of recurrences (14 (9.8%) vs 10 (7.0%), respectively, the over all rate: 8.4% p=0.523), and the mean follow up period. ($48.1{\pm}36.6$ vs $36.5{\pm}24.4$ months, respectively). Conclusion: There were advantages to use synthetic absorbable staple line reinforcement over the usual method for the treatment of primary pneumothorax in regard to the duration of an indwelling chest tube and the hospital stay, but here was no significant difference between the groups for postoperative recurrence.

Impaction with a severely dilacerated root is seldom reported, especially in the maxillary incisor. It is probably because of the high clinical difficulty associated with bringing the dilacerated tooth into proper position, and the high chance of failure due to ankylosis, external root resolution, and root exposure after orthodontic traction. Even the successful cases may need periodontal surgery to improve the unesthetic gingival shape. However, it has previously been reported that an impacted maxillary central incisor was successfully treated by proper crown exposure and orthodontic traction. This article presents a case of an invertedly impacted maxillary right central incisor with a developing dilacerated root, which was aligned into proper position after orthodontic traction composed of two stages of a closed eruption technique.

The purpose of this study is to analyze the early experience of the laparoscopic adhesiolysis for the intestinal obstruction due to postoperative adhesion. Seven patients were included in this study. The median age of those patients was 13, and there were 3 males and 4 females. Previous diagnosis and surgical procedure were various in seven cases, including small bowel resection with tapering enteroplasty, Boix-Ochoa fundoplication, Ladd's procedure with appendectomy, mesenteric tumor resection with small bowel anastomosis, ileocecal resection and anastomosis, primary gastric repair, and both high ligation. A successful laparoscopic adhesiolysis was performed in one who had high ligation for inguinal hernia and had a single band adhesion. Six out of 7 (86%) cases needed to convert open surgery due to multiple and dense type of adhesion. In conclusion, laparoscopic approach with postoperative small bowel adhesion seems safe. However, it might be prudently considered because of high rates of conversion in children.

Purpose: The aim of this study was to evaluate the changes in bone density and reduction of time consumed for osteogenesis by $PostPlant^{TM}$ Calcium and to find out efficacy of $PostPlant^{TM}$ Calcium by comparing the group prescribed with $PostPlant^{TM}$ Calcium with the group without $PostPlant^{TM}$ Calcium prescription. Material and methods: The experimental group of 18 patients with 25 dental implant placement and the control group of 7 patients with 9 dental implant placement were randomly selected from the patients who visited prosthetic department of Dankook University Dental Hospital since July, 2006 (IRB Number ; 20060710). The experimental group was instructed to take $PostPlant^{TM}$ Calcium for 6 months after the implant surgery while the control group was instructed not to. Both experimental and control group were assigned for measurement using $Osstell^{TM}$ Mentor and $Periotest^{(R)}$ and radiographic examination was performed using specifically manufactured Aluminum Step Wedge. The results were compared and analyzed. Results: 1. According to the $Osstell^{TM}$ Mentor measurement, both the experimental and control group showed increase in values as time elapses and the experimental group showed significantly higher rate of increase (P < .05). 2. According to the $Periotest^{(R)}$ measurement, both the experimental and control group showed decrease in values as time elapses. In addition, greater decrease can be seen in the experimental group but no statistical significance was found. 3. By examining the radiographic images, both the experimental and control group showed tendency of increase in bone density. In addition, greater increase can be seen in the experimental group but no statistical significance was found. Conclusion: Clinically, taking $PostPlant^{TM}$ Calcium medicine for a long period of time after implant placement is expected for a better prognosis.

Purpose: Open lateral release and complete lateral release have been conducted as a surgical method in patients with patellofemoral malalignment. But authors sought to find out the best method by conducting selective release, with minimal excision of the involved lesion, and comparative analyzing the result, as postoperative satisfaction and complication. Materials and Methods: Over the 68 patients of 90 cases who underwent arthroscopic release, among 94 patients of 129 cases who underwent lateral retinacular release, from January 1993 to June 1998 were followed up prospectively. A radiological evaluation of patellar inclination, patellar tilt, congruence angle, and Q-angle and a clinical evaluation of HSS-Knee score and modified patellar score were used for analysis data before operation and data at 1 year and 5 year after operation. Results: According to the radiologic evaluation, the patellar tilt and translation revealed improvement of the results, from $13.4^{\circ}$ and 12.1mm to $3.6^{\circ}$ and 3.8mm with arthroscopic lateral complete release, and from $12.3^{\circ}$ and 11.2mm to $4.8^{\circ}$ and 5.2mm with selective release, and from $13.6^{\circ}$ and 12.3mm to $3.3^{\circ}$ and 3mm with open release. But they were not significantly related to the clinical results. HSS-Knee score was 84.2%(48/57), 81.8%(27/33), 82.1%(32/39) and modified patellar score was 82.5%(47/57), 81.8%(27/33), 82.1%(32/39) respectively, which revealed satisfactory results. And no significant difference among the operative methods were shown. Conclusion: Arthroscopic lateral retinacular release which is one of the surgical method for patellofemoral malalignment enhances rehabilitation and satisfaction of the patient, by releasing the involved retinaculum within lesser surgical extent, compared to open and complete lateral release without complications such as adhesion.

A 10-year-old spayed female Shih-tzu dog with a left-sided caudal abdominal swelling of 2-month clinical duration was referred to the Konkuk University Teaching Hospital (KUVTH). We confirmed the presence of an abdominal mass by radiography and ultrasongraphy. A gossypiboma was identified between bladder and small intestines at surgery and removed. The resulting peritoneal adhesion was severe. But, the peritoneal defect did not allow easy repair of the abdominal wall. Therefore, polypropylene mesh (PPM) was used in repair. The patient was good condition after surgery with no caudal abdominal swelling. We followed the patient for the next 6 months with no complication.

Idiopathic mediastinal fibrosis is very rare. We report two cases of a 41-year-old man and 65-year-old man who presented with backache and vocal cord palsy, subsequently confirmed to be idiopathic mediastinal fibrosis. Preoperative chest computed tomography showed a mediastinal mass and thoracoscopic biopsy was preformed. The mass was hard, dense and partially calcified, and adhered the adjacent mediastinal structure. Postoperative medical treatment was not performed, and during 5 and 7 month follow-up has not demonstrated any complication.

Purpose: This study was aimed to evaluate the effect of rhPMP-2 coated implants on alveolar ridge augmentation in dogs. Materials and methods: Six Beagle dogs were used in this study. Six 8.0 mm long anodized surface titanium implants were placed 5 mm into the mandibular alveolar ridge following 6 month of healing period after extraction. Each animal received three implants coated with rhBMP-2 and three uncoated control implants using the randomized split-mouth design. Radiographic examinations were undertaken immediately at implant placement (baseline), at weeks 4 and 8 after implant placement. The amount of bone augmentation was evaluated by measuring the distance from the uppermost point of the coverscrew to the marginal bone. Implant Stability Quotient (ISQ) values were measured immediately at implant placement and 8 weeks after implant placement. For the statistical analysis, Man-Whitney ranksum test and Wilcoxon signed rank test of SPSS 12.0 software were used (P=.05). Results: The BMP group exhibited radiographic vertical bone augmentation about $0.6{\pm}0.7$ mm at 8 weeks later while controls showed bone loss about $0.4{\pm}0.6$ mm. There was significant difference among the rhBMP-2 group and controls in bone level change (P<.05). The ISQ values were significantly higher in the BMP-2 group than the control group at 8 weeks later (P<.05), while there was no significant difference at surgery. Conclusion: Within the limitation of this study, the rhBMP-2 coated on anodized implant could stimulate vertical alveolar bone augmentation, which may increase implant stability significantly on completely healed alveolar ridge.
