【評論主題】38.下列何種情況較不需要藉助平衡性咬合(balanced occlusion)來增加可撤式局部義齒的穩定性?(A)上顎全口義齒,下顎甘迺迪第一類(Kennedy Class I)可撤式局部義齒 (B

【評論內容】(C)上顎甘迺迪第一類(Kennedy Class I)可撤式局部義齒,下顎甘迺迪第二類(Kennedy Class II)可撤式局部 義齒  沒有平衡咬合的雙側接觸,全口義齒在側方移動很容易受重力掉落(D)上顎甘迺迪第二類(Kennedy Class II)可撤式局部義齒,下顎甘迺迪第一類(Kennedy Class I)可撤式局部 義齒

【評論主題】31.可撤式局部義齒(removable partial denture)製作時析量器(surveyor)的操作,尋找置入及取出途徑(path ofinsertion and removal)時,下列

【評論內容】

Rest那些是析量完知道undercut 後才能決定的所以一定放最後,直接秒解,選A

【評論主題】54.引起風濕熱(rheumatic fever)的細菌為下列何者?(A)group A streptococci (B)group B streptococci (C)group A staphyl

【評論內容】Rheumatic fever may develop if strep throat or scarlet fever infections are not treated properly or after strep skin infections (impetigo). Bacteria called group A Streptococcus (group A strep) cause these infections. It usually takes about 1 to 5 weeks after strep throat or scarlet fever for rheumatic fever to develop. Rheumatic fever is thought to be caused by a response of the body’s defense system — the immune system. The immune system responds to the earlier strep throat or scarlet fever infection and causes a generalized inflammatory response.

【評論主題】48.可用來矯治第一大臼齒異位萌出(ectopic eruption)的裝置為下列何者?①矯正彈性分離器(orthodonticelastic separator) ②Halterman裝置 ③Hum

【評論內容】①矯正彈性分離器(orthodonticelastic separator) 明顯必選②Halterman裝置 用power chain拉開第一大臼齒

【評論主題】62.依據歐洲兒童牙科醫學會(The European Academy of Paediatric Dentistry, EAPD)2009年對於兒童使用氟化物之臨床指引,建議3至6歲兒童使用牙膏之氟

【評論內容】含氟牙膏的標準就是1000ppm,對任何年齡層的人都一樣其餘的量都不夠。換個方式考而已

【評論主題】24.下列何者為使用閉合型弧線(closing loop)關閉拔牙空間時,增加彎折gable bend的主要目的?(A)減少額外的力矩(moment)(B)讓拔牙空間相鄰牙齒的牙根平行(C)增加彈性範

【評論內容】

根據Contemporary Orthodontics Ch16. Closing loop mechanics 節錄如下Root-Paralleling Moments... If the legs of a closing loop were parallel before activation, opening the loop would place them at an angle that in itself would generate a moment in the desired direction. Calculations show that unacceptably tall loops would be required to generate appropriate moments in this manner, so additional moments must be generated by gable bends (or their equivalent) before the loop is placed in the mouth 如果loop兩側原本是平行的,那activate之後會產生bodily movement的moment,雖然crown移動但產生一個旋轉的結果,而這個我們不希望的旋轉可以透過增加一個moment of couple來去控制抵銷->舉例而言 牙齒往後退 crown distal tipping, root相對mesial tipping可以簡單想成一個旋轉,但此時額外增加一個couple讓root往distal 轉,那這樣可以讓整體合力變成讓translation就是root-paralleling的效果
