中文摘要 | 鐘擺矯正器已經被證實是一種有效且安全移動臼齒的方式。然而,它的使用上仍然有三種主要的缺點:一、因為錨定喪失所造成的前牙外展。二、對於要維持已獲得的臼齒後移,會有一定的難度。三、當在後續治療時,若面臨前牙全體後拉,容易造成臼齒恢復至原先的位置。頭帽及Nance裝置是一般用來解決這些問題的方法,然而,在頭帽的使用上,病人配合是決定成功與否的主因;而當移除鐘擺矯正器,換上Nance裝置來維持成果時,又常會造成上顎組織發炎更嚴重。本報告提供使用骨釘搭配鐘擺矯正器來取代傳統的方式,同時又不需要病人的配合。為了達成上顎臼齒後移,骨釘種植的位置是以顳下嵴 (infrazygomatic crest) 較為適宜。本報告介紹此種方法的治療過程及其所造成的效果;病例的結果顯示以骨釘搭配鐘擺矯正器的方式有不錯的成效,在未來是一種令人期待的方式。 |
英文摘要 | Three major disadvantages associated with the pendulum appliance during molar distalization were commonly discussed. There are: (1) flaring of the anterior teeth due to loss of anchorage, (2) difficulty maintaining the gain of molar distalization, and (3) tendency to round-trip the molars while the anterior teeth are retracted. Headgears and Nance appliances are the common resolutions to overcome these disadvantages. However, patient's compliance is the determining factor for success when a headgear is used and inflammation of the palatal vault usually occurs immediately after the replacement of the pendulum appliance by the Nance appliance. This article documents the use of mini-screws as a replacement of headgears and Nance appliances. The mini-screws are preferably placed into the infrazygomatic crests to assist pendulum appliances to produce a rapid molar distalization, with little or no need of patient's compliance. We use one of our cases to demonstrate the procedure and effect of a combination of the pendulum appliance and the mini-screw. The results suggest that combined application of the pendulum appliance and mini-screw is promising. |
