[摘要]目的:观察自体骨植骨修复第二磨牙远中骨缺损的临床疗效。方法:纳入2015年10月-2017年10月笔者医院收治的因
拔除下颌阻生第三磨牙致第二磨牙远中骨缺损的80例患者为研究对象。按抽签随机方法分为两组。观察组:40例,拔牙后行
自体骨植骨;对照组:40例,拔牙后不植骨。观察两组手术前后第二磨牙远颊角骨缺损深度(ODD)、探诊深度(PD)及临

分法(VAS)及术后症状严重度评估量表(PoSSe),评估两组术后疼痛及术后症状严重度。结果:观察组术后7d及术后6、
12个月ODD均显著低于术前及对照组(P <0.05),术后6、12个月CAL均显著低于对照组(P <0.05)。观察组手术时间、肿

与对照组比较,差异无统计学意义(P >0.05)。术后6个月,CBCT显示观察组可见不规则自体骨,新骨密度不均匀;对照组
见自缺损底部伴新骨生成,骨密度较为均匀。术后12个月,CBCT显示观察组不规则自体骨较前显著减少,缺损区顶部伴骨白

Abstract:
Abstract: Objective In order to observe the clinical effect of autogenous bone graft in repairing distal bone defect of second
molar. Methods 80 patients with distal bone defect of the second molar caused by the extraction of impacted mandibular third
molars admitted to our hospital from October 2015 to October 2017 were included as research objects. According to the random
method of drawing lots, the patients were divided into two groups, 40 cases in each group. The observation group received
autogenous bone grafting after tooth extraction, while the control group received no bone grafting after tooth extraction. The
depth of defect (ODD), the depth of exploration (PD) and the level of clinical attachment (CAL) of the distal buccal horn of the
second molars were observed before and after operation.The operation time, degree of opening, degree of swelling, occurrence
of adverse reactions, bone mass and morphology were compared between the two groups. Visual analogue scale (VAS) and
Postoperative Symptom Severity Assessment Scale (PoSSe) were used to evaluate the postoperative pain and severity of
symptoms in the two groups. Results ODD in the observation group was significantly lower than that in the preoperative
and control groups 7 days after operation and 6 and 12 months after operation (P <0.05), and CAL in the 6 and 12 months
after operation was significantly lower than that in the control group (P <0.05).The operation time and swelling degree of the
observation group were significantly higher than those of the control group (P <0.05), and the opening degree was significantly
lower than that of the control group (P <0.05).There was no significant difference in PD, VAS score, PoSSe score and incidence
of adverse reactions between the observation group and the control group (P >0.05).At 6 months after operation, CBCT showed
irregular autologous bone and uneven new bone density in the observation group;In the control group, new bone formation was
seen at the bottom of the defect, and the bone density was more uniform.At 12 months after operation, CBCT showed that the
irregular autologous bone in the observation group was significantly reduced, the top of the defect area was accompanied by
bone white line formation, and the bone density was relatively uniform; In the control group, new bone formation was obvious
and trabeculae were weak. Conclusion Compared with non-bone grafting, autogenous bone grafting has obvious effect on
repairing distal and middle bone defect of the second molar and is safe.
