中文摘要 | 牙根尖外吸收是矯正治療後常見的後遺症之一,其發生率因病人篩選、測量方法、治療時間與牙齒的移動方式差異性大,造成不同文獻的統計結果之差異。眾多學者試圖找出具決定性的預測因子,但近期的人體試驗及臨床統計,皆發現矯正治療之牙根吸收的發生及嚴重度爲多重因子交叉影響。臨床上,矯正醫師若發現病患具外傷史、牙根形狀變異,或是上顎前牙需要大量位移、需長時間主動施力等,且病患又爲成人時要格外注意。這些牙根吸收高危險群的病患,在治療前必須被充分告知矯正治療後的副作用,並在矯正過程中配合根尖放射線照影追蹤。 |
英文摘要 | External apical root resorption is one of the common sequela following orthodontic treatment. The incidence of reported root resorption during orthodontic treatment varies widely because of the great variation in the patient selection, measurement method, time differentials and tooth movement mechanism. Numerous studies have been conducted, attempting to establish the factors causing root resorption among the orthodontic patients. Recent clinical and laboratory investigations find the degree and severity of external apical resorption during orthodontic tooth movement is multifactorial. Caution should be exercised in orthodontic patients with tooth trauma history or having abnormal shaped roots, in whom the clinicians plans to large displacement of the anterior teeth, or in patients who have been in the active treatment for a longer than usual period of time, especially for the adult patients. These high risk patients should be fully informed before the orthodontic treatment. Periodic follow-up with perioapical radiographs for the patients is strongly recommended. |
