Purpose: This study evaluated the prognosis and survival rate of SLA (Sandblasted, Large-grit and Acid-etched) implants and it also evaluated the prosthodontic complications and the associated factors. Methods: Twenty seven patients (14 men and 13 women, mean age: 54.9) who visited Chosun University Hospital Implant Center with the chief desire for placement of an implant in an edentulous area from March, 2008 to December 2008 and who received placement of a SLA implant ($Implantium^{(R)}$, Dentium Co., Korea) were selected for this study. Results: The average follow-up period was 15 months and the study was based on the treatment records, radiographs and clinical examinations. A total of 69 implant cases were retrospectively assessed for the width and length of the implant, the primary and secondary stability, the combined surgery, the employed bone graft material and barrier membrane, the status of the opposing tooth, implant failure and the prosthetic complications. During the follow-up period (average: 15 months), the accumulative survival rate of the 69 implants in 27 patients was 100%. Complications such as infection, sinusitis and fixture exposure after surgery were seen for 5 implants in 4 patients. Complications such as screw loosening, contact loosening and peri-implant gingivitis after prosthodontic treatment occurred in 7 cases (10.14%). Conclusion: This study reports placement of SLA implants may cause various complications, yet the final accumulative survival rate was 100%. The SLA implant ($Implantium^{(R)}$) has an excellent clinical survival rate and outcome.

Purpose: Orthognathic surgery is required in patients with severe skeletal disharmony and facial asymmetry, which results in functional and esthetic improvement. Recently, bimaxillary surgery has become generalized. Establishment of the occlusal plane among several other factors included in the surgery plan is a major consideration for the diagnosis and treatment plan and it is also an important factor for postoperative stability. Methods: In this study, we assessed postoperative stability of occlusal plane, B-point, and pogonion point on 20 patients who underwent two-jaw surgery in the Chosun Dental Hospital from 2000 to 2007. Preoperative and postoperative states and at least a one year postoperative follow-up were compared. Results: The postsurgical relapse volume of the occlusal plane to the SN plane and the FH plane was $-0.26{\pm}2.8^{\circ}$ and $-0.44{\pm}3.29^{\circ}$, respectively and after two-jaw surgery, the stability of occlusal plane was maintained. The horizontal relapse degree was $0.85{\pm}0.46$ mm and $0.76{\pm}0.48$ mm, respectively, and the vertical relapse degree was $1.16{\pm}0.36$ mm and $1.13{\pm}0.71$ mm of the B point and the Pogonion point at the time after minimal 1 year. Conclusion: The vertical relapse amount was shown to be slightly larger than the horizontal relapse amount.

Purpose: The purpose of this study was to examine the appropriate degree of set-back of the mandible by evaluating the rate of relapse after surgery. Methods: Among the patients who visited our hospital from January 2002 to January 2007 and who underwent orthognathic surgery, of the patients available for follow-up observation, the rate of relapse after surgery was investigated according to the set-back degree. The patients were divided into groups by the degree of set-back, and relapse was evaluated by the radiographs performed the day after surgery, 6 months after surgery, 1 year after surgery, 2 years after surgery and 3 years after surgery. Results: In cases that exceeded the limit of posterior movement of the mandible (13 mm) or that had the wrong position of the condyle, a greater tendency toward relapse was shown. Conclusion: Based on the results of this study, among the cases that required a large amount of posterior movement of the mandible, two jaw surgeries accompanied by bilateral sagittal split ramus osteotomy (BSSRO) and LeFort I osteotomy are recommended.

Background/Aims: Endoscopic submucosal dissection (ESD) has been widely performed. However, procedure related-complications and the risk of tumor recurrence are limitations. We analyzed the clinicopathological characteristics of patients who underwent curative additional gastrectomy (gastrectomy) after ESD. Methods: The clinical characteristics of cases underwent gastrectomy after ESD were retrospectively analyzed. Results: Between January 2002 and August 2010, 1,512 cases underwent ESD for early gastric cancer (n=511) or adenoma (n=1,001). Thirty-two cases (2.1%) underwent gastrectomy after ESD. Thirty cases (2.0%) were EGC and 2 cases (0.1%) were adenoma. Extended indication, larger tumor size and piecemeal resection were risk factors for gastrectomy after ESD. According to the causes of gastrectomy, 13 cases underwent gastrectomy due to complications (40.6%; bleeding in 9, perforation in 4), and 19 cases based on pathological results (incomplete resection in 13, lymphatic invasion in 6). In cases with incomplete resection, the rate of residual tumor and lymph node metastasis after gastrectomy was 69.2% (75% lateral margin, 60% deep and 75% both) and 7.7%, respectively. Three (50%) of the 6 cases with lymphatic invasion had lymph node metatstasis. Conclusions: The causes of gastrectomy after ESD were the procedure-related complications, the incomplete resection and lymphatic invasion. For complete and curative ESD, endoscopists should try to minimize complications and determine the depth of invasion accurately before ESD. (Korean J Gastroenterol 2012;59:289-295)
