본 연구는 교정치료 종료 후 치아동요도의 종단적 계측을 통해 치아 주위조직의 안정화가 언제 나타나는지 살펴봄으로써 교정치료 후 유지장치 장착기간 설정에 도움이 되고자 시행되었다. 고정식 교정장치로 치료가 종료된 20명의 환자를 대상으로 교정장치 제거 직후 그리고 2년까지 3개월 간격으로 Periotest를 이용하여 상악 양측 중절치부터 제1대구치까지 치아동요도를 계측하고 교정치료 후 시간 경과에 따른 동요도 감소 양상을 비교 분석한 결과, 처음 6개월은 급한 양상으로, 다음 6개월은 보다 완만한 양상으로 감소하였고, 이후는 계속 감소하는 양상을 보였으나 통계적으로 유의한 차이를 보이지 않았다. 이상의 결과는 교정치료 후 치아 주위조직의 안정화는 1년이 지나서야 어느 정도 이루어짐을 그리고 처음 6개월은 매우 불안정함을 나타내는 것으로, 교정장치 제거 후 유지장치가 치료 후 1년간은 필요함을, 특히 처음 6개월 동안은 매우 중요함을 시사하였다.

Abstract ▼ AI-Helper

Objective: The aim of the present study was to evaluate the changes in tooth mobility following orthodontic treatment and to obtain information regarding the guideline of retainer wear duration during the post-treatment period. Methods: The sample consisted of twenty patients who had been treated with edgewise appliances. The mobility of the maxillary teeth from the central incisor to the first molar was measured bilaterally by way of the $Periotest^{(R)}$, a non-invasive, electronic device that provides an objective measurement of the reaction of the periodontium to a defined impact load. Tooth mobility was monitored at the time of the removal of the orthodontic appliances and subsequently at three-month intervals during the two years following appliance removal. Results: Tooth mobility decreased rapidly for the first six months and then decreased at a slower rate during the next six months; no statistically significant decrease in mobility was observed during the second year following appliance removal. Conclusions: The results of the present study suggest that adequate tooth stabilization is critical during the first six months following appliance removal and that continued wearing of retainers is recommended at least until twelve months after the completion of orthodontic treatment.

제안 방법

the mandibular arch for some individuals. In the current study, the use of o_이y maxillary teeth as samples was felt to be sufficient, in that the main objective of the study was to investigate the change in mobility according to time elapsed after appliance removal.
The purpose of the present study was to evaluate the changes in tooth mobility using the Periotest® protocol following orthodontic tooth movement and to obtain information regarding the timing and required duration of periodontal stabilization during the retention period.

대상 데이터

O_미y maxillary teeth were selected as samples in this study. Schulte and his associates8 investigated the Periotest values of the maxilla and mandible dentitions.
Twenty orthodontic patients who had been treated with edgewise appliances were used as subjects in this study. They were selected regardless of age, sex, or treatment modality (eg.

데이터처리

Mean and standard deviation of Periotest values (PTV) were calculated for each tooth, and the total PTV was computed. A repeated measures ANOVA was performed to determine the statistical significance of the differences between time intervals, and the contrast method12 was used for pairwise comparisons. Each measurement was compared with the previous measurement as the contrast.

undertaken. The comparison of the relative mobility at appliance removal and at three-month intervals during the two years following appliance removal indicated that there was a rapid reduction in tooth mobility during the initial six months, a slower decrease after six months, and no significant decrease after twelve months. The results of the present study suggest that the early retention period, the first six months, is critical for stabilizing the periodontal tissue, and that mechanical retention is indispensable at least up to twelve months after orthodontic treatment.
