Objective To evaluate the relevant systematic reviews/meta-analyses that focused on the prevention and treatment of complications after impacted tooth extraction. Methods The systematic reviews/meta-analyses on the prevention and treatment of complications after impacted tooth extraction were searched in PubMed, The Cochrane Library, CBM, CNKI and WanFang Data from inception to September 30th, 2012, and a total of 15 professional journals and the references of included studies were also retrieved manually. Two reviewers screened the literature according to the inclusion criteria and extracted the data. Then the AMSTAR was used to evaluate the quality of the included studies, and the GRADE system was used to evaluate the quality of evidence. Results A total of twelve relevant systematic reviews/meta-analyses were included, of which five focused on the prevention and treatment of dry socket, six on the prevention of swelling, seven on the prevention and treatment of pain, six on the prevention of limitation of mouth opening, two on the prevention of infection, three on the prevention of bleeding, and one on the treatment of nerve damage after tooth extraction. Based on AMSTAR, seven studies were minor limitations and five studies were moderate limitations. Based on GRADE system, two was high quality of evidence, twelve were moderate, nine were low, and seven were very low. Conclusion Currently, the systematic reviews/meta-analyses on the prevention and treatment of complications after impacted tooth extraction can provide some references for clinical practice, which should be combined with the real condition by clinical doctors when making an evidence-based decision. However, it also suggests performing more high quality and large sample studies to prove this conclusion.
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.
