第 20 題
20.有關上顎單顎全口義齒（single complete denture）之製作，下列敘述何者最正確？
- A 因下顎對咬牙存在，咬合平面（occlusal plane）大致決定，故面弓轉移（facebow transfer）非必要
- B 下顎之齒列常需做適當之咬合調整，以去除上顎排牙之咬合干擾
- C 下顎若雙側大臼齒（molar）缺失，可採短化牙弓（shortened dental arch）咬合設計，以減少裝戴下顎可 撤式局部義齒之異物感
- D 上顎單顎全口義齒於後牙區之排牙，必要時要排列成錯咬（crossbite），如此則不需達成平衡咬合 （balanced occlusion）之排列
思路引導 VIP
當我們要讓一個「活動的塑料底座」與一排「位置參差不齊的天然骨骼組織」達成完美的動態接觸時，若要確保這個底座在說話或咀嚼時不會翻覆，你認為我們應該對那些「固定不動的天然組織」預先做什麼樣的形態處理？

Oh, you actually got this one. Impressive.
- Apparently, some students still grasp the painfully obvious: when fabricating an upper single complete denture against a lower arch of natural teeth, those teeth rarely cooperate. Decades of neglect often leave them in a state of clinical chaos—think tilting, over-eruption, and an occlusal plane that resembles a roller coaster. And yet, somehow, we still need stability for our denture. Shocking, isn't it?
- The solution, for those of us who have actually touched a patient, involves achieving bilateral balanced occlusion. This isn't magic; it's just basic mechanics. To eliminate interferences and prevent the denture from becoming an projectile, one must perform occlusal adjustment or restorations on those problematic lower natural teeth. Yes, we actually have to shape them into something resembling an ideal occlusal curve, like the Curve of Spee. Revolutionary.
