LUTING AGENT 優缺點

優點
缺點
注意事項
編號
Zinc phosphate
發展悠久
溶解度高、leakage
用於傳統cast restoration
1
Polycarboxylate
生物相容性 (較不刺激牙髓)
溶解度高、低強度
不要增加水粉比
2
Glass ionomer
透明
溶解度高、leakage
moisture control
3
Resin ionomer
溶解度低、leakage
吸水、發展時間短
勿用於ceramic restoration
4
Composite resin
溶解度低
厚度大、生物刺激
bonding resinmoisture control
5
Adhesive resin
溶解度低、黏著力強
厚度大、發展時間短
moisture control
6
Reinforced ZOE
生物相容性
低強度
僅用於retention很好的情況
