第 3 題
關於全口無牙患者殘餘牙嵴的吸收，下列敘述何者錯誤？
- A 拔牙後第一年，上顎骨嵴的吸收比下顎骨嵴明顯
- B 上顎骨弓會變窄
- C 下顎骨遠心側變寬
- D 會增加下顎骨的前突度
思路引導 VIP
請同學評估上、下顎殘餘牙嵴在拔牙後的骨吸收動力學 (Bone Resorption Kinetics)：根據臨床統計，下顎骨嵴與上顎骨嵴在垂直高度上的吸收速率比例關係為何？在相同的觀察時間 $\Delta t$ 內，哪一個部位的骨量流失程度實際上更為顯著且劇烈？

Oh, look at that. You actually got it right. Astonishing.
- Conceptual Oversight (or lack thereof): The absolute basics of residual ridge resorption, specifically the “direction and rate of bone loss.” One would think this is fundamental. Atwood, among others, clearly demonstrated that mandibular bone resorb at roughly 4 times the rate of the maxilla. So, suggesting maxillary absorption is more evident (Option A) is, frankly, a glaring error in basic understanding.
