无痛口腔麻醉仪联合超声骨刀在埋伏上前牙正畸牵引治疗的临床应用
Clinical application of painless oral anesthesia instrument combined with piezosurgery in the orthodontic trac-tion of impacted maxillary anterior teeth
摘要
Abstract
Objective To investigate the clinical efficacy of painless oral anesthesia combined with piezosurgery compared with ordinary cassette syringe combined with high speed turbine handpiece in the Fenestration operation of orthodontic traction of impacted maxillary anterior teeth. Methods A total of 128 cases of impacted maxillary anterior teeth were treated with Fenestration operation and orthodontic traction, and the patients were randomly divided into two groups. Group A (64 patients) received painless oral anesthesia combined with piezosurgery. Group B (64 patients) re-ceived ordinary cassette syringe combined with high speed turbine handpiece. The cooperation of fenestration and the swelling and pain after operation were compared between the 2 groups. Results The proportion of 0 andⅠin the an-esthesia group was 45.3%and 31.3%respectively, and the conventional group 0 and I accounted for 32.8%and 20.3%respectively. The difference between the two groups was statistically significant (Z=-2.676, P<0.05). The pateints' co-operative degree in group A was better than that in group B (P<0.05). The ratio of pain and swelling in the anesthesia instrument combined with Piezosurgery group was 81.2%, the conventional group had a grade I ratio of 59.4%, and the anesthesia instrument combined with Piezosurgery group was lighter than the conventional group, The difference was sta-tistically significant (Z=-2.777, P < 0.05); anesthesia combined with Piezosurgery group after surgery accounted for 81.2%of the swelling, the conventional group of pain accounted for 71.9%, There was significant difference between the two groups (Z=-2.097, P < 0.05). Symptoms and signs as swelling and pain degree in group A were relatively minor than those in group B (P < 0.05). Conclusion It is worthy clinical promotion to use Painless oral anesthesia com-bined with piezosurgery in the fenestration and orthodontic traction of impacted maxillary anterior teeth, for its better co-operation and minor post-surgery reaction.关键词
