A 52-year-old man was referred to our clinic for an 11.3 mm nodule in the left lower lobe that was discovered on a chest computed tomography (CT) scan. Eleven small nodules were subsequently found in both lungs. Initially, we performed a transthoracic needle aspiration using CT scan guidance. The pathologic report showed a few clusters of atypical cells that were suspicious for malignancy. The positron emission tomography images revealed multiple lung nodules scattered throughout both lungs. The largest nodule (11.3 mm) in the left lower lobe did not have any discernible fludeoxyglucose uptake. For pathologic confirmation, we consulted a thoracic surgeon to perform the video-assisted thoracoscopic surgery. The final diagnosis was minute pulmonary meningothelial-like nodules (MPMNs). MPMNs are benign in nature, and only a few cases require treatment. However, when clinicians are suspicious of potential malignancy, a pathological correlation is essential, even if the final diagnosis is MPMNs.

하악 유견치의 조기탈락은 임상에서 흔히 관찰되는 현상으로 후에 영구치열에서 총생의 징후라 할 수 있으며 향후 영구 전치의 배열상의 문제점이나 부정교합을 유발할 수 있다. 영구 측절치가 맹출될 때 맹출 공간이 부족할 경우 인접해 있는 유견치 치근을 흡수시키면서 맹출하게 되고 그 결과 유견치가 조기에 탈락하게 되는데, 이 경우 영구 하악 영구 절치들이 설측으로 경사지게 되면 상악 절치들과 교합 접촉이 상실되어 상악 절치들이 과맹출됨으로써 수직피개교합 및 수평피개교합이 깊어지며 악궁둘레길이는 감소된다. 유견치가 편측으로 상실된 경우는 상기 현상 이외에, 영구 절치들이 조기 상실된 부위의 공간으로 경사지게 되어 정중선이 틀어지게 된다. 보통 4 mm 이하의 공간부족은 순차적인 유치의 disking과 passive lingual arch를 사용하여 leeway space를 보호하는 것만으로도 해결이 가능하며 4~6 mm 공간부족은 상기 술식과 함께 악궁의 전후방 및 측방확장으로 어느정도 해소할 수 있다.

Korean medicated diet (KMD) is not a simple combination of food and Chinese drugs, but a special carefully constructed diet made from Sasang constitutional medicines, food and condiments under the theoretical guidance of diet preparation based on differentiation of symptoms and signs of traditional Sasang medicine (TSM). It combines the functional efficacy of medicine with the delicacy of food, and can be used to prevent and cure diseases, build up one's health and prolong one's life. Korean traditional medicated diet has a long history of development. Although influenced by Chinese medicine, Korean traditional medicine has been developed into a unique system of traditional medicine that has surpassed the continental medical practice, sublimating itself into a native medical practice suitable to Korean lifestyles and physical constitutions. In the 19th century, Lee Jema's Sasang medicine (medicine of four types of energy determining the physical constitution) was introduced. It is an integration of mind and body according to the individual's physical constitution that is categorized allowing a customized method of treatment ideal for each category-making the content of Korean traditional medicated diet even richer. The characteristics of Korean medicated diet are as follows: (1) Laying stress on the wole, selecting medicated diet on the basis of differential diagnosis. (2) Suitable for prevention and treatment, outstanding in effect. (3) Good in taste, convenient for taking. KMD refers to drink and food according to certain prescriptions, by processing and cooking that can be used either for prevention and cure of diseases, or for health care and recovery. The purpose of this review is to introduce TSM and KMD based on Sasang constitutional medicines.

전치부 개방 교합은 다양한 원인이 복합적으로 작용하고, 진단에 따라 효과적인 치료 계획과 적절한 유지 방법을 선택할 수 있다. 대부분의 경우 교정과 악교정 수술을 통해 안정적인 교합을 얻고, 기능과 심미를 회복한다. 하지만 전체 치열에서 심한 우식증이 있는 경우 광범위한 수복이 필요하게 되므로, 보철 수복을 통해서도 교합을 재형성할 수 있다. 본 증례는 심한 우식을 동반한 골격성 전치부 개방 교합 환자에서 안모 분석 및 진단 납형으로부터 가장 효과적인 치료로 전악 보철 수복을 선택하였다. 교합력을 균등하게 분산하고 심미적인 임시 수복물을 제작하였고, 악간 관계 평가, 혀 등 연조직의 적응, 입술과의 조화를 관찰하고 수정하였다. 충분한 기간 동안 사용한 임시 수복물을 CAD/CAM (Computer-aided design/computer-aided manufacturing)을 이용하여 단일구조 지르코니아 최종 보철물로 이행하였고, 치료 종결 후 3개월 간 주기적으로 관찰하였을 때 만족스러운 결과를 얻었다.

Occlusal disease is comparable to periodontitis in that it is generally not reversible. Occlusal disease, however, like periodontitis, often maintainable. It does itself to treatment and when restorative dentistry is utilized it becomes, in that sense, reversible. Moreover, a systematized and integrated approach will lead to a prognosis that is favorable and predictable. This approach facilitates development of optimum oral function, comfort, and esthetics, resulting in a satisfied patient. Such a systematized approach consists of four logical phase : (1) patient evaluation, (2) comprehensive analysis and treatment planning, (3) integrated and systematic reconstruction, and (4) postoperative maintenance. An integrated treatment plan is first developed on one set of diagnostic casts, properly mounted on a semiadjustable articulator using jaw relationship records. This is accomplished by using wax to make reconstructive modifications to the casts. These modified casts become the blueprint for planned occlusal changes and the fabrication of provisional restorations. The treatment goals are : (1) comfortably functioning temporomandibular joints and stomatognathic musculature, (2) adherence to the basic principle of occlusion advocated by Schuyler, (3) anterior guidance that is in harmony with the envelope of function, (4) restorations that will not violate the patient's neutral zone. This report shows the treatment procedures for a patient whose mandibular position has been altered due to posterior bite collapse. Migration of the maxillary anterior teeth had occurred, and the posterior occlusal contacts showed pathologic interference. Precise diagnosis using mounted casts was executed and prosthodontic reconstruction by the aid of an unconventional orthodontic correction on maxillary flaring was planned. An unconventional orthodontic correction can be accomplished by using preexisting natural teeth, which can be modified for use in active tooth movement or splinted together for orthodontic anchorage. This technique has an advantage over conventional fixed appliance orthodontic therapy because it can accomplish tooth movement concurrently with restorative and periodontal therapy. On occasion, minor tooth movement can be necessary to achieve the optimum occlusal scheme, crown form, and tooth position for the forces of occlusion to be displaced down the long axis of the periodontally compromised teeth. Once the occlusion, periodontal health, and crown contours for the provisional splinted restoration are acceptable, the final splinted restoration can be similarly fabricated, and it becomes an excellent orthodontic retainer.
