一、拔牙的适应症 1.牙体因龋蚀损坏过大,无法保存治疗的。 2.牙齿因牙周炎松动严重,丧失了咀嚼功能的。 3.多生牙、外伤牙、残余牙根等。一句话,拔的是不能治疗的坏牙。一般常犯的错误是:“牙疼就拔”。结果把许多治疗机会失掉;虽消除了一时的牙疼痛苦,却使患者永远丧失了牙齿,降低了以后长期的咀嚼功能。这是必须注意避免的。 First, the indications for tooth extraction 1. Dental caries damage is too large, can not save the treatment. 2 teeth due to periodontitis loose serious loss of chewing function. 3. More raw teeth, trauma teeth, residual roots and so on. In short, pull the bad teeth can not be treated. The common mistake is: “Toothache to pull.” The results of many treatment opportunities lost; although the elimination of temporary painful toothache, leaving patients with permanent loss of teeth, reducing the long-term future chewing function. This must be avoided.
