Atraumatic dental extraction preserves not only the bone, but also maintains the gingival architecture, hence allows immediate or late dental implant placement. The incidence of fracture of roots and buccal cortical plates increases when wrong force is used. Currently, there is insufficient literature evidence with regard to the appropriate method for application of arm and wrist force at the time of dental extraction.
Therefore, the aim of the present study was to compare the efficiency of arm force only versus arm force plus wrist movement during closed extractions.
The patients who underwent extractions of right upper molars ( = 50) in the Oral and Maxillofacial Surgery Department were selected for the study after obtaining Informed Consent. The patients with grossly decayed broken teeth and mobile teeth were excluded. The procedure was carried out by interns and was observed by three maxillofacial surgeons of more than 5 years of experience independently.
It was observed that 30% of the trainees used arm only force during dental extraction and were unaware about it. The time taken for tooth removal in the group which used arm and wrist force was significantly lesser ( < 0.001). It was also observed that the breakage of tooth and alveolar bone fracture was more common with the group who used only arm force.
From the results of the present study, it can be concluded that during exodontia procedures, the principle of using arm and wrist facilitates safe and easy removal of tooth with less time.
无创拔牙不仅能保留牙槽骨，还能维持牙龈结构，从而允许即刻或延期植入牙种植体。使用不当力量时，牙根和颊侧皮质骨板骨折的发生率会增加。目前，关于拔牙时手臂和手腕力量的适当应用方法，文献证据不足。
因此，本研究的目的是比较在闭合性拔牙过程中仅使用手臂力量与手臂力量加手腕运动的效率。
在获得知情同意后，选择口腔颌面外科拔除右上磨牙的患者（n = 50）进行研究。排除有严重龋坏折断牙和松动牙的患者。该操作由实习生进行，由三位经验超过5年的颌面外科医生独立观察。
观察到30%的实习生在拔牙时仅使用手臂力量，且对此并不知晓。使用手臂和手腕力量的组拔牙所需时间明显更短（P < 0.001）。还观察到，仅使用手臂力量的组牙齿折断和牙槽骨骨折更为常见。
从本研究结果可以得出结论，在拔牙过程中，使用手臂和手腕的方法有助于安全、轻松地拔牙，且用时更短。
