The objective of the present study was to perform a fracture analysis on fractured implant fixture after use in vivo and make clear the cause & mechanisms of failure. In case of fatigue fracture, the fractured surface represents fatigue striation. Fatigue striation indicate the progression of the crack front under cyclic loading, are characteristic of stage 2 crack growth. The site of crack initiation and stage 1 crack growth were not easily identified in any of the failure, presumably because of the complex microstructural features of the polycrystalline sample. In case of fractured by overload, dimpled or cleavage surface were observed. Using the interpretation of characteristic markings(ratchet mark, fatigue striation, dimple, cleavage et al) in fracture surfaces, failure events containing the crack origin, crack propagation, material deficiency could be understand.

The characteristics of dental treatment makes the dental staff frequently contact with patient directly. Also the daily use of high-handpieces, sharp instruments, and needles often causes bleeding on oral cavity. Therefore, the risk of cross transmission grows up. The pathogen from dental practice could spread on not only the practice itself but also the dental laboratory with contaminated impressions and prosthesis. Dental clinic staffs (dentists, dental hygienists and dental technicians) should recognize all the patients have a possibility of cross contamination, and try to prevent the transmission of infection by proper infection control. In this study, we review the articles about disinfection methods and chemical infection agents used for dental impressions, and try to figure out the suitable and effective infection control system of dental impressions.

Paclitaxel is known as a potent inhibitor of microtubule depolymerization. It leads to mitotic arrest and cell death by stabilizing the spindle in various cell types. Here, we investigated the effects of paclitaxel on the proliferation and cell death of rabbit articular chondrocytes. Paclitaxel inhibited proliferation in a dose- and time- dependent manner, determined by MTT assay in rabbit articular chondrocytes. We also established paclitaxel-induced G2/M arrest by fluorescent activated cell sorter (FACS) analysis. Paclitaxel increased expression of cyclin B, p53 and p21, while reducing expression of cdc2 and cdc25C in chondrocytes, as detected by Western blot analysis. Interestingly, paclitaxel showed the mitotic catastrophe that leads to abnormal nucleus division and cell death without DNA fragmentation through activation of caspase. Cell death by mitotic catastrophe in cells treated with paclitaxel was suppressed by inhibiting G1/S arrest with 2 mM thymidine. These results demonstrate that paclitaxel induces cell death via mitotic catastrophe without activation of casepase in rabbit articular chondrocytes.

Optimal treatment of the torn posterior cruciate ligament (PCL) remains controversial. The type of tibial fixation (transtibial vs inlay), the femoral tunnel position within the femoral footprint (central, eccentric or isometric), and the number of bundles in the reconstruction (single-bundle vs double-bundle) are controversial issues. The PCL has a better chance of spontaneously healing than the anterior cruciate ligament (ACL) because of a rich blood supply (near the branch of the middle genicular artery) and coverage with a thicker synovium. In general, for easier passage of the graft and full visualization of the original ligament attachment site during the precise positioning of the tunnel, the remaining PCL fibers are usually debrided during reconstruction. However, the remaining remnant structures would significantly contribute to the posterior stability of the knee joint, the healing of the graft, preserving proprioceptive function of the mechanoreceptors in the PCL. Double bundle PCL reconstruction may result in some surgical complications because of increased complexity of making tunnel. Therefore, single bundle PCL reconstruction with remnant preservation seems to be an effective procedure.

Ankylosing spondylitis causes ankylosis of the spine due to ossification of the articular cartilage and ligaments around the vertebral body as well as the sacroiliac joint. This pathophysiology limits joint movement and, in many cases, causes pain and deformity of the spine. If this disease is left untreated, it ultimately causes ankylosis and ossification of the whole-body joints. The symptoms generally develop before age 30 years, and the gradual progression of the disease adversely affects the physical function, professional ability, and quality of life. This increases the likelihood of developing psychiatric disorders, such as depression. The authors are aware of this severity and introduce recent trends and studies to prevent surgical treatment with various medications before systemic ossification. This paper presents various surgical treatments and complications in patients who were unable to prevent progression and underwent surgical treatment.

This is a case report of complete mouth rehabilitation in a patient with generalized attrition and loss of posterior support. After analyzing the condition of the temporomandibular joint, multiple implants were placed to restore collapsed occlusion. Fixture/abutment level intraoral scanning was done instead of using conventional impression materials which entail multiple bite registration for cross-mounting. A 'jaw motion tracking'device, 'digital face-bow transfer', and 'double scan technique' which enables duplicating temporary restoration to definitive restoration were used to fabricate definitive prostheses. By using various digital techniques, complete mouth rehabilitation was done with minimal chair time in a patient with unstable occlusion.

Purpose: The purpose of this study is to evaluate the relationship between trochlear medial facet osteophyte (TMFO) and elbow flexion in the elbow joints without trauma history. Materials and Methods: Twenty five patients, who underwent computed tomography without elbow trauma history, were reviewed. Patients were checked for osteophyte or loose bodies in the coronoid and olecranon sides. The height and length of TMFO were measured. Results: The average elbow flexion contracture was $18.6^{\circ}$, and further flexion was $112.1^{\circ}$. The TMFO height and length was 2.2 mm and 4.7 mm, respectively. The average elbow further flexion was $105.1^{\circ}$ in the coronoid block group (n=14) and $119.1^{\circ}$ (p=0.011) in the coronoid free group (n=11). The relationship between further elbow flexion and TMFO was significant with a partial correlation coefficient of 0.687(p<0.000) in the TMFO length. Conclusion: Elbow joints with longer TMFO length decrease further flexion.

봉독은 거풍습(祛風濕), 지통(止痛), 해경평천(解痙平喘), 소종강압(消腫降壓)의 효능으로 오랫동안 통증과 염증성 질환을 치료하는데 이용되어져 왔는데 최근에는 면역관련질환치료에 응용하여 좋은 결과가 보고되고 있다. 본 연구는 Rheumatoid arthritis와 유사한 형태의 대표적 실험모델로 알려진 실험용 쥐의 Type II collagen 유발 관절염(Type II collagen induced arthritis : CIA)의 활액에서 봉독약침이 단백분해효소와 유리기 손상에 미치는 면역억제효과를 알아보기 위해 실행되었다. 본 실험에서는 CIA가 유발된 실험용 쥐에 봉독약침($5{\mu}l/kg$)을 처리한 실험군과 대조군으로서 CIA 유발 쥐에 생리식염수를 처리한 군(CIA군), 정상적인 쥐에 생리식염수로 처리한 군(정상군)으로 구분하여 각 군들의 일련의 표본에서 세포질, 리소좀, 간질성 단백분해효소의 활성과 유리기로 인한 단백질 손상정도를 (carbonyl 유도체를 측정하여)서로 비교하였다. 그 결과 각 군의 활액표본에서는 많은 종 류의 단백분해효소가 정산군보다 CIA군에서 유의하게 활성이 높았으며, 봉독약침($5{\mu}l/kg$)을 처리한 군에서 효소들의 활성이 유의하게 감소하였다. 그러나 각 군들의 혈장표본에서는 이 효소들의 활성은 서로 유의한 차이가 없었다. 이는 혈장속의 면역반응과 연관되리라고 추측되는 단백분해효소들의 활성변화는 병인적 측면에서 RA와 같은 염증성관절 질환과는 큰 상관성이 없다는 것을 의미한다. Carbonyl 유도체 측정으로 평가한 유리기 손상은 활액과 현장표본에서 모두 봉독약침($5{\mu}l/kg$)을 처리한 군에서 유의성 있게 감소하였다. 이상의 결과로 볼 때 단백분해효소와 유리기의 활성은 RA의 병인학적 측면에서 모두 잠재적인 중요성을 가지고 있으므로 향후 새로운 RA치료법은 이들 단백분해효소의 활성저해와 유리기의 소거능을 포함해야 한다고 사료되며 봉독약침은 이러한 2가지 효능을 포함한 효과적인 치료라고 평가된다.

This article is to report a new technique for reconstruction of the anteromedial and posterolateral bundles of anterior cruciate ligament by separate tensioning and fixation of the each bundle. Method : Tibial and femoral tunnels were made with conventional technique of anterior cruciate ligament reconstruction. Tibial tunnel was enlarged $5\~7$ mm in anterior-posterior direction to make oval it in cross section. When preparing the Achilles tendon allograft, bone plug portion was trimmed as the conventional technique. The tendinous portion was trimmed as two separate bundles by dividing the tendinous portion longitudinally, so the graft is shaped like 'Y'. The bone plug portion of allograft was inserted into the femoral tunnel and fixed with absorbable cross pins. Two ligamentous portionss of the distal part of the grafts were tensioned separately at the external orifice. Anteromedial bundle was fastened under maximum tension with the knee flexed 90 degrees by post-tie method. The posterolateral bundle was fixed by the same technique with the knee in full extension. Then, an absorbable interference screw was inserted between the two bundles upto the upper end of the tibial tunnel, to get more initial rigidity of the reconstructed graft as well as to locate the two bundles in more anatomic position.
