中文摘要 | 一般矯正治療,對於齒槽骨和牙齒大小長度總和的不調和或上下顎骨骨骼性的大小、位置不對稱,其處置原則通常都以上下顎第一小臼齒或第二小臼齒等4齒做為拔除對象來進行矯正治療。但有時只有上下小臼齒之拔除並不能得到良好的結果。此時如增拔上下第一大臼齒,則可使大臼齒區域的近遠心關係及病人側貌得到良好的改善。此篇文章的主要目的即以骨骼性或齒槽性之嚴重上顎或上下顎前突病例,在拔除第一小臼齒矯正處置後,因必要再拔除大臼齒繼續處置,最後得一良好側貌的報告。 |
英文摘要 | For an orthodontic case with the discrepancy of the discoordination between the length of palate bone and tooth size or for a case with skeletal discrepancy of the unsymmetry upper and lower jaw in their size and position, the most common treatment is to extract the upper and lower first or the second premolar. But in some special cases olny four first premolar or two first premolar: two 2nd premolar extraction cannot lead to a goad result. In these case, another four first molars extraction is a good choice to reach a good mesial and distal relationship between upper and lower molar area and get a good profile. This article is a report of sever maxillary protrusion or bimaxillary protrusion cases. They had four first premolar extraction, but the outcomes were not so satisfied. So four first molars were extracted later, and this contributed to a good profile. |
