问题 单项选择题

增强修复体固位力的方法不包括

A.适当的预备体聚合度
B.选用合适的黏结材料
C.增加黏固剂膜的厚度
D.良好的黏结条件与技术
E.设计合理的辅助固位形

答案

参考答案:C

解析: 修复体的主要固位力来自于摩擦力和黏着力。为了利用摩擦力增强修复体的固位,在预备患牙时可采取以下措施:增大修复体和制备牙的密合度,增大接触面积,适当的预备体聚合度,设计合理的辅助固位形,点角、线角要清楚以增大摩擦力。增大黏着力措施有:增大黏着面积,黏着力与黏着剂的厚度成反比,粘固剂的稠度要适当,良好的黏结条件与技术等。因此答案C不符。

How do apology languages work? Have you ever tried to apologize, only to be refused? It may be that you were offering a partial apology in a “language” , that was foreign to your listener.The five languages of apology include:

Apology Language 1: “I am sorry.”

List the hurtful effects of your action.Not “I am sorry if …”, but “I am sorry that…”.You might ask if they want to add any points that you have not recognized.

Apology Language 2:“I was wrong.”

Name your mistake and accept fault.Note that it is easier to say “You are right” than “ I am wrong”, but the latter carries more weight.

Apology Language 3: “ What can I do to make it right?”

How are you now? How shall I make amends(弥补) to you? How can I restore your confidence that I love you— even though I was so hurtful to you?

Apology Language 4: “I’ll try not to do that again.”

Engage in problem-solving.Don’t make excuses for yourself such as, “Well, my day was just so…” Instead, offer what you will change to prevent yourself from putting them in the same bad situation again.

Apology Language 5: “Will you please forgive me?”

Be patient in seeking forgiveness.They may need some time or greater clarification of your input from Apology Languages 1-4.

Finally, your apology may not be accepted, but at least you know that you have been faithful in offering a sincere olive branch of peace.
