門牙做全瓷冠是很正確的選擇,不僅美觀上可以做到以假亂真,而且在牙肉的地方也不會
有黑邊的產生~~~有些高等級的全瓷冠也非常的耐用!!
但是門牙全瓷冠其實也是考驗一個醫師假牙功力的高度技巧性工作!!
患者要知道的就是~~一堆患者在那邊選哪裡價錢低,結果做出來的結果不滿意,
這樣真的明智嗎?
一般醫師製做全瓷冠的方式我就不說明了,沒有所謂的對或錯,你付出多少代價
獲得多少東西是天經地義的事!不是貴就一定好品質,但是便宜沒有好品質的機率會更高!!
一般如果是一次要做好多顆前牙全瓷冠的話(3顆以上),
假牙專科的作法:
先取模(這模我們稱診斷模型),最後會再翻出一個用來計劃跟作診斷臘型.....
最後用診斷臘型翻出臨時牙套的薄薄的外殼....
意思就是你如果只是做1顆或2顆牙的話,空間就是這麼大,基本上沒啥搞頭,
所以不需做啥計劃,但是如果你是好幾顆牙都要一次做的話,
因為變動的空間範圍大,所以你可以盡量的分配好每顆牙的空間跟外型比例~~
在美容牙科裡面也會有所謂的黃金分割比!包含你的牙齒如果有轉了角度或是有傾斜等等,
就會在這時候修正!完成後會拿診斷臘型跟病患做討論,要知道美觀是非常主觀的!!
你的牙齒當然由你決定(合理的狀況下),牙醫師只是單純把它實現出來!
最後利用定案的外型所翻出來的臨時牙套薄外殼就很重要了!!
臨時牙套的薄外殼就是把牙齒磨小的參考用界線~~根據每種全瓷冠的特性(強度..美觀)
不同,有不同的修磨的量,也就是要磨到多小~~當然牙醫師也有可能卯起來狂磨,
反正厚度的要求是最小厚度要求,磨越多你假牙厚度當然就越厚,但是你的牙齒結構就....
所以當牙醫師磨到一定的完成程度的時候,就會用臨時牙套去做測量,牙科器械裡面
有專門量假牙厚度的工具,用這樣的方式去控制你磨掉的量有沒有足夠!一邊磨一邊量...
因為要求的是厚度要能很精準.....但是這工作是很費工!!
最後修磨的時候再用1:5增速手機(一般連醫院都不會備這東西了,因為成本太高)
在3萬轉的狀況下精細的打磨磨亮!還有前牙的邊緣還要盡量的往牙肉下延伸~~
有種種細微的要求要達成才能完成完美的門牙全瓷冠!!
要知道自然牙如果沒問題幹嘛去修它咧?如果之前沒有咬起來怪怪的,保證一定是假牙
有問題!可能厚度修磨不夠,導致假牙裝上去之後變太厚了~~
因為所有的假牙都要有一定的厚度強度才會夠,全瓷冠假牙厚度不夠而破裂是會發生的!!
不要以為3M LAVA就不會破!!
而專科在收費上最基本的全瓷冠應該就會在3~4萬起跳,大概比一般診所貴個1~2萬吧!
但是他得重點就是高品質!!但是當然也要你有那個預算才行啦.....
