선천결손된 상악 측절치와 수복 불가능한 대구치들의 심미수복을 위한 다학제 진료

박철완,Park, Chul-Wan 대한심미치과학회 2017 Journal of the Korean Academy of Esthetic Dentistr Vol.26 No.2

성공적인 심미치과치료를 위해서는 종종 교정과, 치주과, 보철과의사의 협진치료가 필요하다. 상실된 치아를 수복하는 경우, 특히 심미가 중요시되는 전치부의 상실치 수복시 임상가는 여러가지 치료방법의 장단점을 고려하여 치료법을 선택해야 한다. 이 글에서는 선천결손된 상악측절치와 발치가 필요한 구치를 가진 환자를 치아교정과 임플란트 수술 그리고 임플란트 보철의 다학제간 진료로 치료한 증례를 보여드리고자 한다. Successful treatment outcome of esthetic dentistry often requires team approach including orthodontist, surgeon and restorative dentist. Clinician should consider various treatment options to restore missing teeth, especially in anterior region. In this article, interdisciplinary treatment of restoring congenitally missing lateral incisor and unrestorable molars will be presented.

전교통동맥류 출혈의 뇌동맥조영술 소견의 분석

박철완,이훈경,김광명,오석전,김남규,정환영,이승로 대한신경외과학회 1990 Journal of Korean neurosurgical society Vol.19 No.8-9

The authors reviewed angiographic findings of 96 cases of ruptured anterior communicating artery aneurysms that were operated at the Department of Neurosurgery of Hanyang University Hospital from Jan. 1986 to June 1990. The results were summarized as followings : 1) Asymmetricity of caliber of A₁ was observed in 71.9% (69/96) and which was 3 times more frequent than that of reported incidence of control group(2∼23%). 2) The incidence of predominance of left A₁ was 54.2% (52/96) and that of right A₁was 17.7% (17/96). Among them, predominant A₁ was operated as afferent artery of aneurysm in 94.2% (65/69). 3) Of 69 cases in which a unilateral A₁ showed predominance, the direction of aneurysm was opposite to the side of predominant A₁ in 66.7% (46/69) and ipsilateral to the predominant A₁ in only 2.9% (2/69). 4) Above findings suggest that it is desirable to approach the anterior communicating artery aneurysm via the side of predominant A₁ when the direction of aneurysm is uncertain on cerebral angiogram.

친수성 프라이머를 이용한 교정용 브라켓 접착시의 전단결합강도에 관한 연구

박철완,차경석,이진우 대한치과교정학회 2002 대한치과교정학회지 Vol.32 No.4

본 연구의 목적은 산부식된 법랑질에 수분이나 타액이 오염되어도 적절한 접착력을 얻을 수 있다고 소개된 교정용 친수성 프라이머를 이용한 교정용 브라켓 접착시 타액 오염 정도에 따른 전단결합강도와 접착 파절 양상을 기존의 소수성 프라이머와 비교함으로써 임상적 유용성을 평가하는 것이다. 사람의 소구치를 강철 원통에 교정용 레진으로 포매하여 만든 시편에 기존의 소수성인 Transbond XT primer와 친수성인 Transbond MIP primer 각각에 대하여 광중합형 접착 레진으로 브라켓을 접착시, 인공 타액을 이용한 오염정도에 따른 전단결합강도를 만능시험기로 측정하고, 접착 파절 양상을 stereomicroscope로 관찰하여 다음과 같은 결과를 얻었다. 1. 건조 상태에서 Transbond XT primer와 Transbond MIP primer의 전단결합강도는 유의한 차이가 없었다. 2. 타액 오염시 그정도에 상관없이 Transbond MIP primer는 Transbond XT primer에 비해 유의하게 높은 전단결합 강도를 나타냈다(p<0.001). 3. Transbond MIP primer는 한겹의 타액 오염시 건조 상태와 전단결합강도의 유의한 차이가 없었으나, 두 겹의 타액 오염시에는 유의하게 낮은 결합강도를 나타냈다(p<0.01). 4. 접착 파절 형태는 타액 오염의 정도에 따라 평균 접착제 잔류 지수가 낮아지는 경향을 나타냈다. Transbond MIP primer는 타액 오염시에도 반 이상이 브라켓-레진 계면에서의 파절을 보였으나, Transbond XT primer는 타액 오염시 대부분의 경우 레진-법랑질 계면에서의 파절을 나타냈다. 이상의 실험 결과, 교정용 친수성인 Transbond MIP primer는 수분 조절이 어려운 임상 상황에서 적절한 결합강도를 얻을 수 있는 좋은 방법으로 생각된다. The purpose of this study was to evaluate the clinical effectiveness of hydrophilic primer, which claim to retain adequate bond strength on moistened enamel resulting from moisture or saliva contamination, by comparing the shear bond strength and adhesive failure patterns of brackets bonded using hydrophilic primer and conventional hydrophobic primer. Brackets were bonded to human premolars embedded in metal cylinders utilizing light cured adhesive, primed with either a hydrophilic primer(Transbond MIP primer) or a conventional hydrophpbic primer(Transbond XT primer). Each sample was exposed to varying degrees of artificial saliva contamination during the priming process. The shear bond strength was measures using a universal testing machine, and the adhesive failure patterns after debonding were visually examined by stereomicroscope and assessed using the adhesive remnant index(ARI). The results were as follows : 1. In dry conditions, no significant differences in shear bond strength between Transbond MIP and Transbond XT primers were found. 2. Trandbond MIP primer exhibited a significantly higher shear bond stregth than Transbond XT primer in saliva-contaminated conditions, regardless of the degree of contamination. 3. When contaminated with one coat of saliva, Transbond MIP primer did not exhibit significant differences in shear bond strength compared to the dry condition. When contaminated with two coats of saliva, Transbond MIP primer exhibited a significantly lower shear bond strength compared to the dry condition. 4. The adhesive remnant index of the adhesive failure pattern had a tendency to decrease, as the degree of saliva contamination increased .Bracket-adhesive interface failure was observed in more than half of the saliva contaminated samples utilizing Transbond MIP primer, whereas the bond failure sites of the Transbond XT primer samples occurred almost exclusively at the adhesive-enamel interface in saliva-contaminated conditions. The results of this study suggest that in cases where moisture control is difficult, Transbond MIP primer is an effective alternative to conventional hydrophobic primers.

전교통동맥류 출혈의 방사선학적 소견의 분석

박철완,김광명,정환영,김남규,오석전,이승로 대한신경외과학회 1992 Journal of Korean neurosurgical society Vol.21 No.6

In anterior communicating artery aneurysm that accounts for about 30% of intracranial aneurysms, it has been pointed out that the hemodynamic factor plays a very important role in all stages such as initiation, growth and rupture of aneurysm. Based upon the relationship between the findings of brain CT and those of cerebral angigram, the authors reviewed 96 cases of ruptured anterior communicating artery aneurysms that were operated on at the Department of Neurosurgery of Hanyang University Hospital from Jan. 1985 to June 1990, to suggest a point referred to which carotid artery should be selected first when direct carotid angiography is inevitable. The results were summarized as followings : 1) Of 96 cases, hemorrhagic evidence was observed in 92 cases(95.8%) and among them, subarachnoid hemorrhage accompanying intracerebral hematoma(37 cases, 38.5%) was the most common type of hemorrhage. 2) Of 96 cases, left A₁ was operated as afferent artery in 61 case(63.5%), right A₁ in 23 cases(24.0%), and both A1, in 12 cases(12.5%). And the direction of aneurysm was to the right in 49 cases(51.0%), to the left in 12 cases(12.5%) and to the midline in 35 cases(36.5%). 3) Of 53 cases which had intracranial hematoma, 28 cases showed unilateral predominance. Among them the predominance of hematoma was opposite to the afferent artery in 82.1%(23/28) and was ipsilateral to the direction of aneurysm in 64.3%(18/28). 4) Of 91 cases which had subarachnoid hemorrhage, 29 cases showed unilateral predominance. Among them the predominance of hemorrhage was opposite to the afferent artery in 72.4%(21/29) and was ipsilateral to the direction of aneurysm in 58.6%(17/29). 5) Above findings suggest that in the cases with suspicious ruptured anterior communicating artery aneurysms on brain CT and direct carotid angiography is inevitable, contralateral carotid angiography should be undertaken at first when intracranial hematoma or subarachnoid hemorrhage shows unilateral predominance on brain CT, and left carotid angiography is preferable than the right one if there is no predominance of intracranial hematoma or subarachnoid hemorrhage on brain CT.
