ObjectiveTo discuss the clinical effects of micro implant anchorage combined with orthodontic positioning in the guided eruption of impacted maxilla anterior teeth.
MethodsThirty-two patients with maxillary impacted teeth treated between 2010 and 2013 were selected, including 13 males and 19 females, aged from 13 to 26 years old, with an average age of (18.5±4.5) years. The extraction of the teeth and the local expansion of the extraction of the teeth were used to provide enough space for the impacted maxilla anterior teeth. The micro implant anchorage combined with orthodontic positioning was applied to treat 32 patients with 39 maxillary impacted teeth. Then, we observed the feasibility and efficacy of the therapeutic method.
ResultsThe 39 impacted teeth were all successfully tracked and well aligned with good periodontal attachment. Pulp vitality test showed that 13 pulp reaction were retarded and 26 appeared normal.
ConclusionThe micro implant anchorage combined with orthodontic positioning is effective in guided eruption of impacted anterior maxillary teeth.
