Abstract
Purpose: To explore the effect of extracting the completely impacted teeth by minimally invasive surgery with preserving the buccal bone plate.
Methods: Eighty-six cases were selected and randomly divided into 2 groups. In the experimental group, a fenestration was made with a ball drill to expose the buccal and lingual margin of crown, and the buccal bone plate was preserved. T-shaped crown cuttings were performed, minimally invasive extraction was conducted.In the control group, the distal and buccal bone plates were removed with a ball drill, the distal and buccal crowns were exposed, and T-shaped crown was cut. The other procedures were the same. The degree of swelling, restricted mouth opening and VAS pain score after operation were observed, the levels of C-reactive protein and anti-hemolytic streptoglobulin were detected by laboratory tests, and the periodontal probing depth(PD), bleeding index (BI), and clinical attachment loss(CAL) of the adjacent second molar were examined 1 month after surgery. SPSS 25.0 software package was used for data analysis.
Results: The swelling degree of the two groups was significantly relieved in the experimental group than in the control group (P<0.05), and there was no significant difference in the degree of mouth opening limitation and pain (P>0.05). The level of C-reactive protein in the control group was significantly higher than that in the observation group (P<0.05). There was no significantly difference in the level of anti-hemolytic streptococcus between the 2 groups (P>0.05). One month after operation, the PD and CAL in the control group were significantly higher than those in the experimental group(P<0.05). There was no significant difference between the 2 groups in BI(P>0.05).
Conclusions: The patients who preserve the buccal bone plate by minimally invasive extraction of impacted mandibular teeth have less reaction and better wound healing.
目的:探讨保留颊侧骨板的微创手术拔除完全阻生牙的效果:选取 86 个病例,随机分为两组。实验组:用球钻开窗暴露牙冠的颊舌缘,保留颊侧骨板。对照组使用球钻去除远端和颊侧骨板,暴露远端和颊侧牙冠,切割 T 形牙冠。其他程序相同。观察术后肿胀程度、张口受限情况和 VAS 疼痛评分,化验 C 反应蛋白和抗溶血性链球菌球蛋白水平,术后 1 个月检查相邻第二磨牙的牙周探诊深度(PD)、出血指数(BI)和临床附着丧失(CAL)。数据分析采用 SPSS 25.0 软件包:实验组肿胀程度明显减轻(P<0.05),两组张口受限程度和疼痛程度差异无显著性(P>0.05)。对照组 C 反应蛋白水平明显高于观察组(P<0.05)。两组抗溶血性链球菌水平无明显差异(P>0.05)。术后一个月,对照组的PD和CAL明显高于实验组(P<0.05)。结论:结论:通过微创拔除下颌阻生牙保留颊侧骨板的患者反应较小,伤口愈合较好。
