回答1:

牙冠修复的步骤为第一,制定计划,看牙齿是不是需要做牙冠,第二步磨,第三部安装。主要分三大步,如果牙齿缺损比较多或通过根管治疗的牙齿,这样牙齿需要做牙冠保护。因为根管治疗或杀过神经的牙齿比较脆弱必须做牙冠,决定做牙冠之后要选择牙冠的材料是烤瓷牙还是全瓷。根据牙齿情况还有结合患者具体要求,如美观要求、牙位要求。决定材料以后就开始做牙体预备,未来牙冠大小需要把牙冠磨小一圈,磨小了以后通过牙冠来恢复外形,调磨牙齿叫牙体预备,预备了以后要取模型或光学印模、石膏模型,取完模型以后在模型上做假牙冠。模型做完了以后再粘在患者嘴里,一般牙冠修复的时间最快1天左右,一般1周左右也可以,现在最快的就是计算机辅助设计和计算机辅助制作,材料和精度方面也可以非常好的。最后是粘接,粘接到嘴里调磨,调磨至邻面接触点、咬合高矮均正常。所以做牙冠需要三步,沟通计划、调磨牙齿、粘上。

牙冠的修复过程是这样的,1,如果牙神经是活髓的话,就得需要先打麻醉药物,死髓的话就不用打麻醉针。然后在进行牙冠的修整,修整好之后采用排龈线吧牙龈与牙齿排开,然后用牙托盘给口腔中的牙齿进行取模,然后用石膏灌注模型,送往加工厂加工假牙,一周过后进行假牙试戴即可。

回答3:

一般来讲,牙齿全冠修复的过程包含前期修复准备。假如患牙已经产生龋坏、牙髓炎症、根尖炎症,必须对患牙进行根管治疗术后,大概1-2个星期才能到医院进行冠部修复准备。
医生首先要评估所剩的牙体组织的牙本质或者牙釉质是否能作为基础固定牙体的结构。如果基础牙体组织不足以对冠部形成固位力的要求,会在原有根管治疗牙根上面进行桩核预先修复,然后才会再进行上部的牙体预备。在桩核冠粘接之后,对患牙进行牙体预备。牙体预备大概时长在30分钟左右,然后进行口内硬模,大概5分钟左右,之后会对口内咬合关系进行制取,制取完成所有硬模以及口腔咬合关系之后,再把修复体送到加工厂,由加工厂技师对于将要进行的冠部修复制作,大概时长是1-2周时间。
目前有计算机辅助可以在口内进行口内修复体的扫描,扫描完成之后,经过设计师的设计,再通过机器切割,可以完成当天制备牙体预备,当天带牙的临床过程。

回答4:

一般是由于平时口腔清洁度不够引起的蛀牙,导致牙齿损伤严重。建议,一般先做根管治疗,然后补牙,再根据缺损的程度做牙套,烤瓷牙。

回答5:

你好,牙冠修复的流程是先检查牙冠情况,然后再根据牙冠情况制定解决办法,如果只是轻微的磨损只要适当的打磨凹凸不平的地方就可以,如果牙冠缺损严重,就需要拆除下来重新咬模型,安装一颗新的牙冠。
