Impacted teeth is because of various reasons (bone, teeth or soft tissue, etc.). that completely is blocked or only partially eruption.The Impacted teeth should not eruption to the normal position of teeth in future Impacted teeth when serious ambush in mucosa or bone become Teeth. Ambush missing teeth lead to dentition, dentition occlusal disorders, adjacent teeth root absorption. In addition to third molar, the maxillary canine impacted is the most common. Many impacted third molars are extracted in clinical treatment. Maxillary canine at the mouth together are essential status,so many of maxillary canines are preserved by orthodontic treatment.Objective: To study orthodontic guided eruption technique for impacted maxillary canines and to explore an effectived orthodontic method for the impacted maxillary canine treatment.Methods: In accordance with the canine root development ,ambush situations, medical imaging and clinical examination, analysis impacted reasons of maxillary impacted canines.It is identified in impacted canines in three-dimensional position, impacted teeth root and the surrounding soft and hard tissue health status. use of orthodontic open gap and surgical exposure United orthodontic to lead and guide Impacted teeth, combined with edgewise technique of direct bond brackets guided impacted maxillary canine eruption.Results: 4 cases of impacted maxillary canine erupted after opend effe- ctive space for impacted canines then the impacted teeth could be moved into alignment with good esthetic and fimctional effect.1 example Impacted maxillary palatal canine ambush by surgical exposure of United orthodontic traction, take into the normal alignment, crown with normal controls .It have no difference with the normal eruption canine, periodontal, gum, pulp health.Conclusion: Orthodontic help open up gap and surgical united orthodontic traction is a sophisticated, reliable and effective treatment of maxillary impacted canines method . |
