본 증례는 뇌성마비가 있는 혼합치열기의 청소년에서 치간이개를 개선하는 다양한 방법을 모색해보았다. 그 중 복합레진을 이용한 보존적 치료는 이동에 어려움이 있는 뇌성마비 환아에서 최소한의 내원 횟수, 짧은 술식 시간, 경제적이며, 가역적이고 단순한 치료법이다. 이를 통해 높은 심미적 만족도와 발음 및 교합력 개선을 통해 본 환아의 삶을 질을 높일 수 있을 것으로 기대한다.

The purpose of this case report was to introduce the concept of orthodontic and orthopedic treatment for a growing patient with Tessier number 0 cleft. A 5-year-old boy patient with Tessier number 0 cleft presented congenitally missing maxillary central incisors (MXCI), a bony defect at the premaxilla, a constricted maxillary arch, an anterior openbite, and maxillary hypoplasia. His treatment was divided into three stages: management of the bony defect at the premaxilla and the congenitally missing MXCIs using a fan-type expansion plate, iliac bone grafting, and eruption guidance of the maxillary lateral incisors into the graft area for substitution of MXCIs; management of the maxillary hypoplasia using sequential facemask therapy with conventional and skeletal anchorage; and management of the remaining occlusal problems using fixed orthodontic treatment. The total treatment duration was 15 years and 10 months. Class I canine and Class II molar relationships and normal overbite and overjet were achieved at the end of treatment. Although the long-term use of facemask therapy resulted in significant protraction of the retrusive maxilla, the patient exhibited Class III profile because of continued mandibular growth. However, the treatment result was well maintained after 2 years of retention. The findings from this case suggest that interdisciplinary and customized approaches are mandatory for successful management of maxillary hypoplasia, bony defect, and dental problems in Tessier number 0 cleft. Moreover, considering the potential of orthognathic surgery or distraction osteogenesis, meticulous monitoring of mandibular growth until growth completion is important.

Orthodontic extrusion is usually performed by means of a fixed orthodontic appliance that utilizes arch wire attached to adjacent teeth and transfers the desired force by elastic from the wire to the root. However, clinicians often encounter cases where the bonding required for tooth traction is not possible because the adjacent teeth have been restored with ceramic or veneer. The purpose of this case report is to describe a modified orthodontic extrusion appliance that is useful when conventional orthodontic treatment is not possible. The modified appliance was fabricated using an artificial tooth, clear plastic sheeting, and a braided fiber-reinforced composite strip that covered adjacent teeth without bonding. It satisfied the esthetic and functional needs of the patient and established the optimal biologic width.

본 연구는 청소년기 교정환자의 치료 협조도에 영항을 주는 요인을 알아보기 위하여, 서울지역의 A치과의원에서 고정식장 치로 교정치료중인 남녀 중, 고등학생 100명으로 설문 조사하였다. 조사기간은 2006년 10월 9일부터 11월 8일까지였으며, 연구결과는 다음과 같다. 1. 대상자의 협조도 총점의 평균은 최소 2점, 최대 14점을 보이며 평균 8.04점이였다. 2. 대상자의 성별, 연령은 협조도와의 관계에서 통계적으로 유의한 차이가 나타나지 않았다. 3. 치료기간에 따른 협조도 평균을 분석해 본 결과 치료기간이 1년 미만이10점, 1~2년이 8.15점, 2년 이상이 6.84점으로 치료기간이 길어질수록 협조도는 지속적으로 감소하였다 (P < 0.05). 4. 치료결정자에 따른 협조도 평균을 분석해 본 결과 본인은 9.17점, 어머니가 7.69점, 아버지가 7.77점으로 본인이 치료를 결정한 경우 협조도가 높음을 알 수 있었다 (P < 0.05). 5. 대상자의 Angle의 부정교합 분류와 협조도와의 관계를 분석해 본 결과 협조도 평균은 I급 부정교합은 8.77점, II급 부정교합은 7.28점, III급 부정교합은 6.89점으로, III급 부정교합보다 I급 부정교합이 협조도가 높음을 알 수 있었다 (P < 0.05). 6. 협조도에 영향을 미치는 요인중 가장 영향력 있는 변인을 알아보기 위햐여 로지스틱 회귀분석으로 분석한 결과 치료기간과 부정교합 분류가 유의한 관련성이 있었다(P < 0.05).

유착, 부적절한 교정치료, 과잉치, 낭종, 비정상적인 맹출경로등의 국소적인 원인으로 인하여 구치부의 매복이 발생할 수가 있다. 매복치는 적절한 치료를 하지 않으면, 교합기능의 상실, 영구치의 상실, 대합치의 정출, 인접치의 치근흡수등을 야기 할 수가 있다. 매복치를 성공적으로 맹출유도하기 위해서는 매복치의 치근형성여부가 중요한 요소가 되며, 매복치의 치근형태, 주위환경등을 유의한 적절한 교정력이 가해져야 한다.

Patients who have impacted tooth are found commonly in orthodontic treatment. Although it is difficult to find the cause of impacted teeth, the most common, causes are prolonged retention of the deciduous teeth, trauma, aberrant sequence of eruption, lack of space and deficiency of Vitamin D. Impacted teeth may lead to esthetic and functional problems and root resorption of adjacent teeth, so we should treat it as soon as possible. Commonly used treatment method is the following: After surgically uncovering of the impacted teeth, a bond of orthodontic appliance is established, and orthodontic traction is started with a removable or fixed appliance. We used the modified lingual arch with a soldered auxiliary appliance in lingual arch for traction of lower impacted teeth. The modified lingual arch could control the magnitude and direction of the applied force with one-arch treatment, and also could give continuous force to impacted tooth without patient patient cooperation. We achieved good results with the modified lingual arch.

Long face patients are characterized by excessive anterior facial height, lip incompetence at rest, anterior open bite, and gummy smile. A major problem is an inferior rotation of the posterior maxilla and upper molars. Long face patients have been the most difficult for orthodontist to treat successfully. In growing patients, the methods for impeding excessive vertical growth have been used high pull head gear, functional appliance, and combined type of two. One significant improvement comes from using a full arch splint to deliver force to the maxilla more vertically. In adult patients, orthodontic camouflage treatment is biomechanically difficult and doesn't work when the problem is primarilly vertical. Surgical maxillary impaction provides a means for successfully treating most of problems. Also, superior reposition of the chin via a mandibular inferior border osteotomy is effective in decrease of lower anterior facial height and correction of the poor chin-lip balance. Post-surgical stability and the physiologic response are good. The coordinated orthodontic and surgical treatment is necessary for solution the difficult skeletal deformity.

Purpose: This study examined the factors influencing the choice of dental clinics by individuals who received orthodontic treatment for malocclusion. Methods: Participants were 320 male and female college students in Daegu and Gyeongsangbuk-do who had received orthodontic treatment in dental clinics for malocclusion. They were surveyed about their choices of dental clinics. Of the 320 questionnaires, 294 (91.9%) were used for analysis, and surveys with insufficient responses or errors were excluded. Results: The factors influencing the choice of dental clinics varied among the participants. Furthermore, factors that most commonly affected their choices were, in order, trust in dentists' skills and medicine used, information from community sources, friendliness of the dentist, friendliness of clinic staff, cleanliness of the hospital, availability of up-to-date medical facilities and equipment, convenience of location, and recommendations by acquaintances. Conclusion: Factors underlying the choice of dental clinics varied among the participants. Typically, these choices were strongly influenced by factors such as reputation, professionalism, and friendliness.

매복치는 기능적, 심미적 장애 뿐 아니라 인접치의 치근흡수 등의 문제를 유발할 수 있으므로 적절한 처치가 필요하다. 매복치의 치료 방법으로는 주기적 관찰, 외과적 노출술, 외과적 노출 후 매복치를 교정하는 방법, 치아이식술, 발치 등이 있다. 이 중 교정적 견인에 사용되는 modified Nance appliance는 환자의 협조를 필요로 하지 않으면서, 견인 와이어를 쉽게 교체할 수 있어서 임상적으로 유용하게 사용될 수 있다. 본 증례들에서 modified Nance appliance를 사용하여 전치, 견치, 대구치 등 상악 내 다양한 위치에 존재하는 매복치의 수술을 동반한 교정적 견인을 시행하여 양호한 결과를 얻었기에 보고하는 바이다.
