15 Q&A Q1: 預計拔除的 牙 齒雖然有 mobility 的現象, 但是對於 occlusion 多少都還有 一些功能, 為什麼最後選擇拔除呢? A1: 主要是因為病患的選擇, 這位病 人最後選擇上顎做 CD, 下顎做 Kennedy Class I division I 的 RPD, 所以參考價值較低 Q2: 未拔 牙前 #17 27 都仍與對咬有 contact, 此時的 VD 是否有參考價值? 製作過程中對於 VD 有哪些需要注意的地 方? A1: 治療中會配戴 interim denture, 會參考病 人使 用的狀況來做修整, 另外發 音 吞嚥 美觀等等也都是需要注意的地 方 Q3: 下顎為何是使 用 wrought wire 而不 用 I bar? A3: 一開始有考慮 I bar, 然 而因為這位病 人軟組織硬組織間的 undercut, 以及後 方是無 牙區的關係, 所以最後使 用 wrought wire Q4:wrought wire 似乎離 gingiva 不到 1mm? A4: 這邊是當初設計時的疏失 Q5:47 原先有考慮做 ortho 去 upright, 那請問這顆 牙 齒留下來或不留下來你所考慮的點是? A5: 不留下來的考量是因為這位病 人本 身的 oral hygiene 很差, 長遠來看這顆 牙 齒最後可能會拔掉, 因此不如 一開始就拔除減少之後重做的可能 ; 另外希望這顆 牙 齒留下來所考慮的是在 RPD 的 distal end 可以有 一個 abutment 提供 support, 增加整個 denture 的 stability 建議 :lingual plate 設計的 支點放在 mesial side 的話, 會失去 support 的作 用, 沒有考慮到 physical movement 沉降的變化,guding plane 會失去原有的效果
