问题 单项选择题

一患者缺失,牙槽嵴丰满,铸造支架式义齿为三臂卡固位体,舌杆大连接体。义齿戴用一周后,主诉义齿压痛、基牙咬合痛。口腔内检查发现:舌系带根部小溃疡,叩痛,义齿各部分密合,咬合不高。

针对而采取的以下措施中,错误的是()

A.增加间接固位体

B.改用RPI卡环

C.改用回力卡环

D.减小游离端基托

E.人工牙减数、减径

答案

参考答案:D

解析:

舌系带根部溃疡说明舌杆位置过低,妨碍了舌的功能运动。基牙疼痛说明基牙负担过重,通过增加间接固位体,改用RPI卡环或回力卡环,以及人工牙减数或减径等可以减小基牙受力,但减小游离端基托面积无此作用,只会增加牙槽嵴局部压力。

Many people find it hard to make friends.  小题1: All it takes is for you to get out of your shell and remember that if you love yourself, others will too. Especially being a teen, making friends can be hard or easy depending on several factors.

Relax. It’s all about confidence---if you are nervous or try too hard to look cool you’ll just act strange. So you won’t make many friends. You will stand out as overdoing(做得过分) something.

You have to act as you have had plenty of friends in the past, so even the “cool” ones will want to speak to you. 小题2: Be relaxed.People will like you for passing a peaceful energy.

Make the first move. Don’t be shy because it won’t help you in anything. Look around for people that seem interesting, and go up to talk to them. A good subject to talk about to anyone is music because almost everybody likes music. 小题3:Try not to get deep when you are first meeting somebody.

小题4: Everyone likes to be heard. So give attention to what others say, look straight in their eyes and show you’re paying attention. If this person feels that you’re listening to him, your new friend will enjoy your company more.

Develop friendships. You may talk to someone now but soon they’ll forget you if you stop.小题5: Say their name as often as you can. When you greet them, say things like, “Hey Alex!”,“What’s going on, Sarah?’’ If you do that every day, they’ll be happy that you care about them and remember them, so they won’t forget you and you will be good friends.

A.It is really not.

B.Be a good listener.

C.Other topics could be movies or sports.

D.Making one or two best friends is usually enough.E. Invite your new friends to go out together with you.

F. Think of good reasons why someone would like to meet you.

G. You’d better take a time to say hi to them every day and ask how they are doing.
