第 35 題
下列何種印模材料最不適合使用於遠伸性可撤式局部義齒(distal extension removable partial denture)的功能性印模(functional impression)?
- A 氧化鋅丁香酚(zinc oxide eugenol)
- B 瓊膠水膠質(agar hydrocolloid)
- C 假牙重襯材料(denture reline material)
- D 多硫化橡膠(polysulfide rubber)
思路引導 VIP
在處理遠伸性局部義齒(distal extension RPD)時,功能性印模(functional impression)的核心目標是為了平衡支柱齒(abutment teeth)與受壓位移後的牙槽脊黏膜關係。請同學思考:在提供的選項中,哪一種材料屬於『熱可逆性水膠質』,且臨床上必須依賴龐大的水冷式牙托才能進行固化(setting),導致其無法像其他材料一樣在口內透過功能性運動來精確記錄組織受壓後的流變狀態?
