中文摘要 | 下顎後牙的長期缺失,會造成上顎對咬牙的過度萌發和鄰接牙向缺牙區傾斜或不當位移,在製作補綴物時會遇到後牙區顎間空間不足的問題,需要矯正治療的幫助,可利用臨時植體來解決傳統錨定裝置的缺點及限制。本病例為二十四歲女性,主訴為無法製作兩側後牙區的假牙,診斷為安格氏一級不正咬合、兩側後牙錯咬,兩側第二大臼齒向近心側傾斜,左上第二小臼齒和第一大臼齒過度萌發。其治療計畫為在左上第三大臼齒無牙塉處植入骨釘,當作上顎弓擴大及上顎臼齒壓入的絕對錨定來源;配合全口固定式矯正裝置,以期能夠改善患者兩側後牙錯咬,恢復正常的咬合功能。在本病例中利用骨釘治療顎間空間不足及後牙錯咬,獲得良好的結果在此提出討論。 |
英文摘要 | This case was a 24-year-old women. She was seeking reconstruction of her bilateral posterior occlusion. According clinical examination and cephalometric analysis, the diagnosis was Angle Class I malocclusion, bilateral posterior crossbite, mesial tipping of bilateral mandibular second molars, and supereruption of left maxillary second premolar and first molar. We presented a treatment plan that included fixed appliance with intrusion of maxillary posterior teeth and expansion of upper arch by using a miniscrew as skeletal anchorage. After the period of sixteen months including four months to achieve intrusion of the left upper second premolar and first molar, we created adequate occlusal clearance for prosthesis. Our case is presented to illustrate the method. |
