药物成份或治疗方案详述: |
每名患者分两次拔除两侧M3M,所有手术均由同一外科医生完成,保证在拔除对侧M3M之前,初始手术一侧的术后反应可以完全消退。 1) 术前常规预防性用药。 2) 患者用抗菌洗必泰漱口水漱口1 min,采用计算机控制的局部麻醉给药系统,用1.7ml Primacaine Adrenaline (1/100000)进行下颌神经阻滞麻醉和M3M牙周浸润。 3) 对照侧术式:采用颊侧翻瓣,于M2M颊侧龈沟内切开,绕过远中颊角,再从远中面向磨牙后区偏颊侧切开约1.5厘米到下颌支,剥离抬起颊侧粘骨膜瓣,避免翻瓣范围过大,特别避免翻起舌侧组织;小心牵拉保护组织瓣,使用高速外科手机圆形钻头在M3M牙冠颊侧远中去骨,充分冲水冷却,显露M3M牙冠颊侧最大径轮廓和釉-牙骨质界(CEJ),注意控制去骨范围,避免去除颊侧外斜嵴;沿釉牙骨质界用裂钻分切,分开牙冠牙根,然后将牙冠进一步切割成舌侧和颊两半,分别去除,使牙根冠方有足够的脱位空间,使用牙挺向近中、向上挺出牙根,如有必要,对多根牙在根分叉处进一步分切,分别去除各牙根。 4) 试验侧术式:采用舌侧翻瓣,切口从M2M的远中颊角龈缘开始,在外斜嵴内侧向远中延伸约1.5cm到下颌支,在 M3M 牙冠和磨牙后区骨表面仔细剥离抬起舌侧黏骨膜组织,显露舌侧骨板边缘,形成无张力的舌侧瓣,颊侧软组织不翻瓣;用骨膜剥离器插入骨与软组织之间轻柔牵开组织瓣,为舌神经提供保护,使用球钻在牙冠表面和舌侧骨板内侧去骨,显露牙冠舌侧边缘和釉牙骨质界(CEJ),舌侧去骨深度约1-2mm,注意避免穿透舌侧骨板;斜行分切牙冠,从舌侧CEJ根方开始向颊侧牙冠最大径冠方使用裂钻分牙,将斜型分切的牙冠进一步分切成舌侧和颊侧半,分别去除,使牙根冠方、舌侧有足够脱位空间,使用牙挺楔入颊侧牙周间隙,向舌侧挺动,使牙根松动,如有必要,对多根牙在根分叉处进一步分切,分别去除各根。 5) 牙拔除后用可吸收明胶海绵填充牙槽窝,丝线缝合软组织。患者进行术后冷敷,保持口腔卫生,口服洛索洛芬钠0.6g每日3次作为镇痛和消炎药物,口服甲硝唑0.2g每日2次、头孢呋辛酯0.25g每日2次,连续3天。 |

Description for medicine or protocol of treatment in detail: |
M3M was extracted twice for each patient, and all operations were performed by the same surgeon to ensure that the postoperative reaction on the original surgical side could be completely resolved before the removal of the contralateral M3M. |

随机方法(请说明由何人用什么方法产生随机序列): |
使用SAS9.4软件生成1-200之间的随机数字表,规定从第一个数字开始,将随机数字分给第1位患者,当随机数字为奇数时则左侧为实验组,右侧为对照组;当随机数字为偶数时则左侧为对照组,右侧为实验组;随后对后续患者连续使用随机数字表进行分组。 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
SAS9.4 software was used to generate a table of random numbers between 1 and 200, which stipulated that starting from the first number, the random numbers were assigned to the first patient. When the random numbers were odd, the experimental group was on the left and the control group was on the |
