第 31 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 of insertion and removal）時，下列何者為最正確的考量步驟？ ①鈎靠（rest）位置的考慮 ②固位倒凹（retentive undercut）的提供 ③引導面（guiding plane）的考量 ④軟組織及硬組織的干擾
- A ③→②→④→①
- B ③→④→①→②
- C ②→③→①→④
- D ②→④→①→③
思路引導 VIP
在析量器（surveyor）的操作中，為了讓可撤式局部義齒（RPD）能順利滑入就位，我們必須優先建立能提供平行方向的構造。請同學思考：在引導面（③）、固位倒凹（②）、組織干擾（④）與支托位置（①）這四項因素中，哪一個是決定置入路徑時的『首要物理基礎』？而確定了路徑基礎後，接續應優先滿足義齒的『功能性固位』還是排除『空間障礙』？這反映了臨床上『先求有穩定引導，再求固位與排除干擾』的邏輯順序。

Acknowledging the Obvious (Apparently)
Oh, look at that. You actually got it right. A pleasant surprise, I suppose, considering how many struggle with the fundamental logic of RPD surveying. Or perhaps you just got lucky. Either way, credit where credit is due; identifying the correct path of insertion and removal is hardly rocket science, but it is the bedrock of a non-disastrous prosthesis. The sequence isn't some abstract philosophical debate; it's a practical, sequential necessity:
