The patient was a 69-year-old male who had decreased VDO and overbite of the anterior teeth due to severe teeth wear. Complete mouth rehabilitation was planned to restore esthetics and function. Due to the presence of a subgingival finish line, poor fit of the margin of the temporary crown, and insufficient oral hygiene management, gingival overgrowth and bleeding occurred in many teeth, and inaccurate impressions were taken. After dividing each arch and taking partial impressions, a transfer coping was made using pattern resin on each working model die, and after being placed on the abutment teeth, a master cast was made through pick-up impression taking to produce prosthesis. In this case, the final prosthesis produced on the second master cast were fitted in terms of proximal contact, marginal fit, vertical occlusal dimension, facial appearance, esthetics, and occlusion. After complete mouth rehabilitation, the patient was satisfied with function and esthetic appearance.

As patients' esthetic expectations increase, there is an increase in demand for cosmetic restorations of anterior and posterior teeth that resemble the natural tooth morphology and color. An example of high-strength all-ceramic systems is zirconia with CAD/CAM application. This case report describes a full-mouth rehabilitation using zirconia all-ceramic crowns supported by upper and lower implants and by a minimal increase in the occlusal vertical dimension in a patient with severe abrasion due to loss of posterior teeth.

Background: Funnel chest is one of the most common anomaly of chest wall, which is manifested by depression of sternum and costal cartilage. Popular operative methods were Ravitch operation and Wada operation. Material and Method: From 1983 to 1996, 21 cases of funnel chest were corrected surgically in the department of thoracic surgery, National Medical Center. Investigated age and sex distribution, combined anomaly,clinical symptom, degree of correction and complication, postoperative satisfaction. We used 2 different surgical methods, one was Wada & its variants(17 cases), the other was Ravitch and it variants(4 cases). Most of operative indications were cosmetic problems. Result: The pre-operative Welch index was 4.188, but this index decreased to 3.46 after the operations.(p=0.046) The degree of correction was higher in Wada & it variant operation than the modified Ravitch operation.(p=0.54) Their results were satisfactory in 20 patients, while unsatisfactory in 1 patient because of a k-wire fracture. There was no recurrence of chest wall depression or postoperative death during the OPD follow up period. Conclusion: We recommend Wada operation in symmetric and small degree of depressive chest wall deformity in preand post school age.

The purpose of this study was to investigate how early retirees spent their days and how daily life was experienced. In order to cover as many aspects as possible of the subject, this study examined sources of life satisfaction/dissatisfaction. Data were drawn from in-depth interviews in which 101 early retirees residing in Seoul. The Majority of early retirees in this study were at least somewhat dissatisfied with their daily life. Content analysis of reasons for life satisfaction/dissatisfaction revealed that the sources were categorized into 6 categories and 66 specific sources. Analysis of sources of life satisfaction revealed that early retirees mentioned most frequently as their sources of life satisfaction in this order: subjective emotions, family relations, stability of economy, positive attitude on retirement. Analysis of sources of life dissatisfaction revealed that life dissatisfaction was intimately connected with the loss of work role, family, unstability of economy, and ill preparation for retirement. Implications for macro and micro alternatives to support early retirees were provided.

구개열 및 구개근의 기능부전 등에 의한 인두문(velopharyngeal valve)의 폐쇄부전으로 인하여 발생하는 구개범인두부전증(velopharyngeal insufficiency)은 흔히 과비성으로 알려진 구음장애를 나타내는 병적현상으로 Von Langenbeck(1861)이 구개 외측 점막성 골막편을, Smith(1895) 와 Ganzer(1920)는 각각 구개 4-판 및 3-판 점막성 골막편을 이용한 수술적 치료법을 통하여 구음장애를 해결하여 주려하였고, 그외 인두후벽의 증대 및 언어보조기 등을 이용한 방법으로 구음장애를 해결하여 주려는 연구가 최근까지 활발하게 이루어지고 있으나 만족할 만한 성적을 거두지 못하고 있는 실정에 있다. 이에 저자들은 구개범인두부전증에 대한 수술적 치료후 증상의 호전정도를 관찰하고, 술후에도 증상의 호전을 보이지 않는 환자의 음성재활에 대한 향후 방향제시에 도움을 주고자 1987년 1월부터 1991년 1월까지 과비성을 주소로 본원 이비인후과에 내원하여 구개성형술을 시행받고 3개월 이상 추적 관찰이 가능하였던 14례의 환자를 분석한 결과 구개범인두부전에 대하여 1차 수술을 시행받은 14례중 5례(36%)에서 정상적인 구음이 가능하였으며 실패한 9례중 5례에 대하여는 재 수술을 시행하였으나 만족할 만한 음성회복을 거두지 못하여 그 원인과 저자들의 술식을 분석 검토함으로써 구개범인두부전증의 치료에 대한 보다 효율적인 방법을 모색하고자 문헌고찰과 함께 보고하는 바이다.

Excessive teeth wear may result in the complications such as esthetic problems, hypersensitivity, and loss of vertical dimension. This clinical report focuses on the causes of severely worn dentition and the full-mouth rehabilitation of a patient with rheumatoid arthritis for 20 years. An interview, clinical and radiological examinations were performed to analyze the causes and decide the treatment plan. After delivery of the final prostheses, a night guard was used to protect the restorations and temporomandibular joints. The patient was satisfied esthetically and functionally.

관절경적 경경골 단일 다발 후방십자인대 재건술은 전통적으로 가장 흔하게 사용되는 사용되는 술기이다. 그러나, 후방십자 단독 파열시 이 술기의 결과에 대한 임상 평가 및 효용성에 대한 임상적 분석 자료가 거의 없는 실정이다. 이 술기를 시행받은 환자군들에서 객관적 슬관절 이완이 존재함에도 불구하고 주관적 슬관절 기능 장애는 우수한 결과를 나타낸다고 인정되어 왔다. 후방십자인대 단독 파열 후 경경골 단일 다발 재건술을 시행한 문헌 10개를 대상으로 잔존하는 후방 이완과 주관적, 객관적인 기능 평가, 활동성 정도, 환자 만족도, 골관절염의 발생 빈도, 술후 합병증을 체계적으로 고찰하였다. 술전 후방 슬관절 이완은 8.38~12.3 mm에서(4문헌) 술후 1.96~5.9 mm으로(9 문헌) 호전되었다. Lysholom 점수는 평균 81~100점이었다(9 문헌). IKDC는 75%에서 정상 또는 거의 정상의 결과를 보였다(6 문헌). 평균 Tegner 활동도는 4.7~6.3점이었다(8 문헌). 이번 고찰을 통한 결과에서 이 술기 후 퇴행성 변화가 관찰되었으며 보고된 합병증은 거의 없었다. 후방십자인대 단독 파열에서 경경골 단일 다발 재건술은 정상 슬관절의 안정성까지 회복하지는 못하나 한 등급 정도의 후방 슬관절 이완의 호전을 기대할 수 있다. 재활 및 운동으로의 회복에 대한 주관적 슬관절 점수는 80점이며 75%의 정상 또는 정상에 가까운 객관적 결과를 보여주었다. 이 술기가 퇴행성 관절염을 예방할 수는 없더라도 이러한 결과는 후방십자인대 재건 술기의 평가에 도움이 될 것으로 사료된다.

Excessive teeth abrasion causes pathologic changes of oral environment and masticatory system due to decrease in occlusal vertical dimension. When establishing new occlusal plane and recovering vertical dimension, accurate diagnosis and analysis are essential. In this case, after appropriate centric relation in elevated vertical dimension was taken using Gothic arch tracer, full mouth rehabilitation was performed. A 70-year-old male patient had the chief complaint that he could not eat due to teeth wear. He showed generalized teeth wear and decreased vertical dimension. Elevation of vertical dimension was planned by model analysis. According to increased vertical dimension, centric relation was recorded using Gothic arch tracer and temporary prostheses were applied. Appropriate occlusion was established by temporary prostheses for 4 months. Final prostheses were fabricated using vertical dimension adapted by temporary prostheses. Through this procedure, satisfactory outcomes were achieved both in functional and esthetic aspects.

본 연구는 1987년 1월부터 1991년 12월까지 연세대학교치과병원 구강악안면외과에 과두 골절이 의심되어 내원한 환자중 임상 및 방사선학적 소견에서 하악과두 골절로 진단되어 비외과적 치료를 받은 12세 미만의 13명의 소아환자를 연구 대상으로 하여 임상 및 방사선학적 소견을 분석하여 다음과 같은 결론을 얻었다. 비외과적인 보존적 또는 기능적 치료를 받은 후의 결과는 양호하였으며, 골의 재생과 개조는 신속하여 골 구조는 기능 중에 가해진 힘에 반응한다는 Wolff의 법칙과 일치하는 듯이 보였다. 두 예의 골절탈구에서 과두의 단축 및 과두가 골절된 악관절에서 clicking음을 보였으나 저작하거나 개구시에 큰 어려움은 없었다. 술후 관찰기간이 불충분하였으나 본 예의 대부분에서 비외과적인 술식에도 만족스러운 치료결과를 보였다.
