The utility model discloses a kind of biodegradable stent for oral and maxillofacial surgery bone defect healing, it includes：Rack body, it is that degradation material such as magnesium alloy is made and with the profile consistent with the defect repair part of oral jaw facial bone；Intensive multiple through holes are offered on the rack body, the diameter of the through hole is inconsistent.Biodegradable stent described in the utility model for oral and maxillofacial surgery bone defect healing can utilize the through hole carrying Gegenbaur's cell on magnesium alloy bracket, magnesium alloy bracket material can gradually be degraded during jawbone defect reparation, the bone tissue that degraded part is newly formed replaces, the purpose of timbering material " early stage optimal load power, noninvasive absorption at a specified future date " can be realized. |
