Objective:To explore the clinical effect of cosed-eruption surgical technique combined with orthodontic traction in the treatment of bone impacted anterior teeth.Methods:32 patients with bone impacted anterior teeth of 35 teeth were selected.The patients first were given orthodontic pioneering impacted tooth adorable out the gap,and then were given fenestration operation. Impacted tooth bonding tooth surface was fully exposed in the operation.It was adhesive with orthodontic traction accessories.After wound healing,traction of teeth was impacted to help germination.Results:In 32 patients,after guided eruption operation,2 cases of 2 impacted anterior teeth were eruption in 2 months after operation,3 patients discontinued treatment due to go abroad,transfer and other reasons.A total of 27 patients with 28 impacted anterior teeth,23 teeth(82.14%) were successful;3 teeth(10.71%) were effective;1 tooth(3.57%) was failed.After cosed-eruption surgical technique combined with orthodontic traction treatment,the 28 impacted teeth were erupted to the normal position;gingival morphology was satisfied;dental pulp vitality was normal;there was no adjacent teeth root absorption and damage.Conclusion:The clinical effect of cosed-eruption surgical technique combined with orthodontic traction in the treatment of bone impacted anterior teeth is better.
