최근 들어 치아의 심미적인 개선을 위해 전치부 보철 치료를 하는 경우가 많다. 하지만 전치부 심미 보철치료이후 환자가 발음, 저작 등 기능적으로 불만족스럽게 생각하는 경우가 종종 있다. 전치부는 심미적으로 중요할 뿐만 아니라 교합과 관련하여서도 중심위 다음으로 중요한 전방유도가 성립되는 부분으로, 잘못된 전방유도 설정으로 인해 구치부의 교합간섭을 초래할 수 있다. 또한 새롭게 설정된 전치부 보철물의 전방유도가 환자의 기능로(envelope of function)과 조화를 이루지 않을 시 환자가 불편감을 나타낼 수 있다. 본 증례는 전치부 심미 보철 이후 부정확한 발음 및 안정적인 접촉이 없어서 불안정한 교합, 전반적인 불편감을 호소하는 환자에서 체계적인 진단과 치료과정을 통해 보철물을 재수복하여 환자와 술자 모두에게서 심미적으로, 그리고 기능적으로 만족스러운 결과를 얻었기에 보고하는 바이다.

전치부 심미 보철에서의 성공은 안모에서의 심미와 구강 내 주의 치아와 치주 조직간의 조화라 할 수 있다. 정상적인 교합평면을 가진 안면대칭의 환자에서는 여러 심미 책에 나오듯 기준을 잘 정하고 그 기준에 맞게 제작하면 별 탈없이 조화롭고 심미적인 보철을 제작할 수 있다. 하지만 안면 비대칭 환자의 경우 안면 대칭의 환자의 기준에 억지로 맞추어 제작하게 되면 심미적이지도 않을뿐더러 기능적이지도 않은 결과로 끝나기 쉽다. 또한 치은 퇴축이 심한 환자의 경우 달라진 치아주위 환경에 맞게 보철의 형태를 부여해야만 치주조직에 조화롭고 심미적이며 자정작용이 뛰어난 보철제작이 가능하다.

PURPOSE. The aim of this systematic review was to address treatment outcome according to attachment systems for mandibular implant overdentures in terms of implant survival rate, prosthetic maintenance and complications, and patient satisfaction. MATERIALS AND METHODS. A systematic literature search was conducted using PubMed and hand searching of relevant journals considering inclusion and exclusion criteria. Clinical trial studies on mandibular implant overdentures until August, 2010 were selected if more than one type of overdenture attachment was reported. Twenty four studies from 1098 studies were finally included and the data on implant survival rate, prosthetic maintenance and complications, patient satisfaction were analyzed relative to attachment systems. RESULTS. Four studies presented implant survival rates (95.8 - 97.5% for bar, 96.2 - 100% for ball, 91.7% for magnet) according to attachment system. Ten other studies presented an implant survival rate ranging from 93.3% to 100% without respect to the attachment groups. Common prosthetic maintenance and complications were replacement of an assay for magnet attachments, and activation of a matrix or clip for ball or bar attachments. Prosthetic maintenance and complications most commonly occurred in the magnet groups. Conflicting findings were found on the rate of prosthetic maintenance and complications comparing ball and bar attachments. Most studies showed no significant differences in patient satisfaction depending upon attachment systems. CONCLUSION. The implant survival rate of mandibular overdentures seemed to be high regardless attachment systems. The prosthetic maintenance and complications may be influenced by attachment systems. However patient satisfaction may be independent of the attachment system.

2-D echocardiographic examination of the aortic root diameter was known to be useful in the selection of the size of the prosthetic valve. Valve-patient mismatch was occasionally a serious problem after valve replacement, especially in aortic valve disease. Preoperative knowledge of the patient`s valve annulus size is therefore of great importance in the surgical management of these patients. So the relationship between preoperative 2-D echocardiographic diameter of the annulus size and replaced prosthetic valve were evaluated. 13 patients were analyzed in this study. 2-D echocardiographic measurements of aortic annulus diameter, as determined from the parasternal long axis view and apical four chamber view, demonstrated a high correlation with actual prosthetic valve size implanted at surgery[r=0.86, p< 0.001, SEE=1.08].

We treated three cases of bone tumors-giant cell tumor, chondroblastoma and malignant fibrous histiocy toma-with a custom-made prosthetic replacement. The patients were followed from 10 months to 18 months, postoperatively. The results of these study are as follows : 1. satisfactory anatomic restoration 2. early ambulation 3. good function 4. biomechanically sound reconstruction.

Extracellular laccase secreted from Pleurotus ostreatus was activated by $Cu^{2+}$ and $Cu^{+}$ . The enzyme was strongly inactivated by 8-hydroxyquinoline, potassium cyanide, sodium azide, sodium bisulfite and 2-mercaptoethanol. The two ionogenic groups, which have pKa values of 5.60-5.70 and 6.70-6.85 respectively, were found to relate with the active site of this enzyme. The oxidation reactions were brought about by initial single electron transfer process on the active site. The enzyme was found to be a metalloprotein which had about 3.9 cupric ions per molecule of protein as a prosthetic group. The enzyme showed a strong peak at 605 nm and a weak shoulder at 330 nm in UV-Visible absorption spectrum. Both signals disappeated upon treatment of the enzyme with 4 electron equivalent ascorbate. These results indicate that type I Cu peak and type III Cu shoulder are present in laccase.

A 51-year-old male was admitted to the hospital with complaints of fever and hemoptysis. After evaluation of the fever focus, he was diagnosed with pulmonary valve infective endocarditis. Thus pulmonary valve replacement and antibiotics therapy were performed and discharged. He was brought to the emergency unit presenting with a high fever (> $39^{\circ}C$) and general weakness 6 months after the initial operation. The echocardiography revealed prosthetic pulmonary valve endocarditis. Therefore, redo-pulmonary valve replacement using valved conduit was performed in the Rastelli fashion because of the risk of pulmonary arterial wall injury and recurrent endocarditis from the remnant inflammatory tissue. We report here on the successful surgical treatment of prosthetic pulmonary valve endocarditis with an alternative surgical method.

골격성 III급 부정교합을 가진 환자에서의 보철 치료는 환자의 전신적요인과 기타 구강내, 외적인 요인을 고려하여 정확한 치료 계획하에 시행되어야 한다. 성인에 있어서 III급 악골관계는 외과적 수술과 교정치료가 선행된 후 보철수복이 진행되도록 계획하는 경우가 일반적이지만 환자의 전신적 요인 등으로 인하여 수술이 불가능한 경우가 있을 수 있다. 이러한 경우에서는 보철로 인한 저작기능의 회복시 좀 더 안정적으로 교합을 유지, 지속할 수 있는 치료가 필요하다. 본 증례에서는 전신질환으로 인하여 수술이 불가한 III급 악골관계를 가진 환자에서 고정성 보철 수복을 통하여 경제적, 시간적으로 효율적이고 기능과 심미를 충족시키는 임상적 결과를 얻었기에 보고하고자 한다.

PURPOSE. Fractures, occlusal adjustments, or marginal corrections after removing excess composite cements result in rough surfaces of all-ceramic FPDs. These have to be polished to prevent damage of the surrounding tissues. The aim of this study was to evaluate the roughness of zirconia, silicate-ceramic, and composite after polish with different systems for intraoral use. MATERIALS AND METHODS. Each set of 50 plates was made of zirconia, silicate-ceramic, and composite. All plates were ground automatically and were divided into 15 groups according to the treatment. Groups Zgrit, Sgrit, and Cgrit received no further treatment. Groups Zlab and Slab received glaze-baking, and group Clab was polished with a polishing device. In the experimental groups Zv, Sv, Cv, Zk, Sk, Ck, Zb, Sb, and Cb, the specimens were polished with ceramic-polishing systems "v", "k", and "b" for intraoral use. Roughness was measured using profilometry. Statistical analysis was performed with ANOVA and $Scheff{\acute{e}}$-procedure with the level of significance set at P=.05. RESULTS. All systems reduced the roughness of zirconia, but the differences from the controls Zgrit and Zlab were not statistically significant (P>.907). Roughness of silicate ceramic was reduced only in group Sv, but it did not differ significantly from both controls (P>.580). Groups Cv, Ck, and Cb had a significantly rougher surface than that of group Clab (P<.003). CONCLUSION. Ceramic materials can be polished with the tested systems. Polishing of interface areas between ceramic and composite material should be performed with polishing systems for zirconia first, followed by systems for veneering materials and for composite materials.
