作者指出:尽管金属基板义齿具有下列优点:(1)固位好,(2)(牙合)磨损少,(3)痛点少,(4)折断发生率低,(5)感觉舒适,(6)温度传导好,(7)可作为稳定的记录基板,(8)腭板薄发音清晰,(9)保护剩余牙嵴,(10)气孔少,(11)在侧咬(牙合)时变形小,(12)精确度高。但在临床上未能广泛应用。总义齿固位的四个物理因素是:附着力,内聚力,大气压力和唾液的粘性。义齿的边缘密封甚为重要。义齿加工后的误差常影响固位。树脂材料的义齿因加工变化使固位力降低,并造成咬合失调,引起痛点。但金属基板无上述情况出现。金属基板义齿虽具有费用高,花时多,衬底较困难及过敏等缺点,但不影响其使用。
The authors note that although metal-based dentures have the following advantages: (1) good retention, (2) less occlusion, (3) less pain points, (4) low breakage, (5) (7) can be used as a stable recording substrate, (8) clear thin palate thin sound, (9) to protect the remaining ridge, (10) fewer stomatal holes, (11) deform during side bite Small, (12) High accuracy. However, it has not been widely used clinically. Four physical factors for total denture retention are: adhesion, cohesion, barometric pressure and saliva viscosity. Denture edge seal is very important. Denture processing errors often affect retention. Denture resin material due to processing changes to reduce the retention, and cause occlusion disorders, causing pain points. However, there is no metal substrate above. Although the metal plate denture with high cost, spend more time, the substrate is more difficult and allergic shortcomings, but does not affect its use.
