中文摘要 | 本文獻回顧,討論了大臼齒經矯正內縮後的牙周反應:在牙周健康的病人身上,是否有牙周囊袋形成,或角化牙齦寬度的改變;<2>在牙周病穩定控制的病人身上,牙周附連生成、第三級根叉癒合,及牙周引導再生術的影響。是否矯正內縮,能藉由牙齒的重新置位或增加細胞活性,進而誘導改善上述問題?另外,傳統矯正內縮,往往會對錨定齒產生不利的作用力與反作用力,故我們亦討論了,<3>暫時錨定裝置的應用,以期簡化治療並提高可行性。矯正內縮量愈多,則建議進一步的牙周囊袋評估;角化牙齦的寬度無統計學上的改變。牙周引導再生術後等半年以上,可做矯正內縮;矯正內縮在牙周引導再生術前施行有其好處。雖然在動物實驗發現,良好的口腔衛生下,矯正內縮力可幫助根叉癒合,同時在骨破壞的起始點,有新牙周附連生成,然相對應的人類實驗仍缺乏,需待長期追蹤的文獻報告;至於暫時錨定裝置提供接近“絕對錨定”,是一個相對簡單、安全而有效的方法。 |
英文摘要 | The present review discusses periodontal reactions related to molar intrusions: <1> the gingival response including pocket formation and keratinized gingival change in periodontally healthy patients; and <2> the effects of attachment gain, grade Ⅲ furcation lesions, and guided tissue regeneration (GTR) in periodontal compromised patients. Whether an orthodontic intrusion can induce or improve these problems by repositioning the teeth and/or increasing cellular activity is a relatively new issue. In addition, conventional orthodontic intrusion is usually accompanied by unfavorable actions and reactions of the anchorage teeth, so we also discuss the application of temporary anchorage devices (TADs) for increasing the feasibility of treatment and its simplification.As greater amount of intrusion is produced, further periodontal evaluation is suggested to determine if pathologic pockets have formed. No significant change in keratinized gingival width was shown. After waiting for more than 6 months subsequent to GTR, intrusion is practical treatment. Intrusion before GTR may have benefits. Although in animal studies, open flap debridement followed by orthodontic intrusion had significant benefits on furcation lesions, and new attachment formation was found at the initial periodontal defect level under good oral-hygiene control. However, most such effects mentioned above still lack corresponding human trials, and further studies with long-term follow-up are needed. TADs which mimic absolute anchorage are a relatively simple, safe, and effective method. |
