根管治療后牙齒明明不疼,為什麼還要戴牙冠?

            

                

                    

                        

                

            

            

                

                    

            

            

                

                    

                        

                            

                                

                        

                    

                    

                        

                            


                                ◆ ◆ ◆◆


                        

                    

                    

                        

                            

                                

                        

                    

                

            

            

                


                    說到牙齒治療,很多人都有不同程度的牙齒齲壞,輕度的齲壞只需要修補填充上牙洞就可以了。但一些嚴重的牙齒齲壞會傷及牙齒神經,讓患者朋友夜不能眠,這個時候就要進行根管治療了。

                    


            

            

                

                    

                        

                

            

            

                


                    根管治療能從源頭上防止牙齒進一步病變,對於牙齒的修復具有非常重要的意義。一般來講,牙髓炎,牙髓壞死和各種類型的根尖周炎都適合做根管治療,包括由於齲齒、隱裂、過度消耗、穿髓等引起的牙髓炎及牙髓壞死不能保留活髓的情況。


                


                    很多患者都不太了解根管治療,今天就來為大家解答根管治療中常見的疑問:


            

            

                

                    

                        

                            

                                

                                    

                                

                                    


                                        牙齒做冠(或嵌體)的原因


                                

                                

                                    

                            

                        

                        

                            

                                


                                    “補牙不做冠,療效少一半。”但是很多患者卻不能理解,在根管治療后,牙齒不疼了,明明補上就可以了,為什麼還要做全冠保護?


                                


                                    其實是因為三個原因:


                                


                                    1、牙齒容易變色


                                


                                    根管治療后的牙齒缺少必要的保護,其抗氧化能力也會明顯下降,受到各種影響后更容易氧化變色,顯得非常不美觀。


                                


                                    2、牙齒容易感染


                                


                                    做過根管治療的牙齒會成為一個空殼,對細菌病毒的抵抗力大幅下降,容易受到各種食物的影響或是感染細菌。


                                


                                    3、牙齒脆弱


                                


                                    根管治療雖然可以從根本上解決牙髓炎、牙周病的問題,但治療也會導致牙齒失去牙髓。失去牙髓后的牙齒由於缺乏必要的營養,會變得比較脆弱不夠堅固,如果依然像以前那樣大力咀嚼,牙齒會更容易出問題。

                                    


                            

                        

                        


                            


                    

                

            

            

                

                    

                        

                            

                                

                                    

                                

                                    


                                        二、牙齒做冠的材料


                                

                                

                                    

                            

                        

                        

                            

                                


                                    1、普通廉價——鎳鉻合金


                                


                                    鎳鉻合金材料,價格較便宜。但是由於金屬內冠長期使用會產生鎳元素析出,15%的使用者有輕度的毒性反應和過敏反應,並在使用者的牙齦處形成鎳金屬的聚集使牙齦發黑,目前已經基本淘汰。


                            

                        

                        

                            

                                

                        

                        

                            


                                2、經濟實惠——鈷鉻合金


                            


                                鈷鉻合金冠稱之為“無鎳無鈹合金”。主要成份是鈷、鉻,其價格介於非貴金屬和貴金屬之間,生物相容性優於鎳鉻合金冠,耐腐蝕,不易出現崩瓷,可以減少牙齦出血及黑色牙齦的現象出現。而且經濟、適合大多數牙齒的修復,后牙固定橋等固定修復。


                        

                        

                            

                                

                        

                        

                            


                                3、強度更高無刺激——貴金屬


                            


                                依據金的含量分為中金(56.7%)、高金(86.7%)兩種,它是最理想的修復材料之一,強度更高,無刺激,而且金與瓷的結合很牢固,與組織的相容性更好,在牙冠與牙齦接觸的地方不會發青。


                            


                                另外,貴金屬冠能在黃金的表面反應自身的顏色,使冠的色彩柔和,美觀性好,完全能滿足美容修復的要求,它還是種植牙的很好材料。


                        

                        

                            

                                

                        

                        

                            


                                4、明星一樣的牙齒——全瓷冠


                            


                                全瓷冠的色澤無論在燈光下和自然光中都能保持自然色,因此成為目前影視明星和公眾人物牙齒美容的寵兒。全瓷冠的通透性和色澤好,美觀效果極佳,生物相容性好,對人體無害。


                        

                        

                            

                                

                        

                    

                

            

            

                

                    

                        

                            

                                

                            

                                


                                    三、根管治療後有哪些注意事項?


                            

                            

                                

                        

                    

                    

                        

                            


                                1、根管治療術醫生需要根據患者的臨床檢查情況,分步分次進行治療,一般來說要分2-4次就診才能完成。


                            


                                2、根管治療充填完畢,一周內可能會出現脹、悶或輕微疼痛,屬正常情況。通常三天以後不適會逐漸消退,恢復正常感覺。


                            


                                3、若根管治療三天後,仍有不適,或出現異常疼痛等問題,應及時與主治醫師聯繫,進行治療和調整。


                            


                                4、患者需配合醫生及時複診。


                            


                                5、根管治療一周內禁食硬食,盡量不用根管治療的一側進行咀嚼。
