The use of in situ autogenous tooth of the crown on the anterior maxilla-mandible to solve immediate implant restoration

Purpose:The use of in situ autogenous tooth or tooth surface of the on the maxilla or mandibular anterior teeth to solve immediate implant restoration the same period in the interim when the issue of natural aesthetics.Method:1、Consistent with the clinical diagnosis and to meet the immediate removal of the upper and lower pre-planting conditions for the 10 cases of jaw teeth,the clinical or lip complete the basic non-defect side,the realization of the need for the same period of transitional implant the whole case.2、In vitro treatment of tooth preparation and provisional crown。Antisepsis,Will be pulled out immediately after cleaning teeth soaking in 10% formaldehyde solution for 10 minutes to deal with;Crown or the tooth surface modification,in accordance with immediate implant clinical height of the expected,in vitro cross-cutting teeth grinding with crowns set aside part of。Crown modification in vitro of three deal with the situation:①Intact morphology,Diamond burs with grinding stone to remove the majority of crowns within dentin,forming a central hollow shell crown,the repair of molar shape and tune the internal space of the implant in place mill base close to the appearance of the form;②small portion of defects in crown、complete Labial side,Grinding defect region,Removal of pathological structure light-cured glass ionomer resin patch,and then shell crown grinding to prepare the way to deal with;③Lingual most defects,the basic integrity of the side lip,the labial tooth surface to retain,in addition to the remaining mill structure,and self-curing resin to form a joint application shell crown. 3、By the bed and the implant abutment preparation.Implant system with reference to the cultivation of selected steps,by the implant bed preparation and implant placement,in accordance with the permanent prosthesis design and to wear the way of direct or indirect method of grinding the appearance of implant abutment form for temporary the use of restoration.4、Tried temporary Since the preparation of good teeth shell crown to wear to the implant abutment,the temporary cement after occlusal adjustment.Conclusion:The use of pull-out from the of the tooth or tooth surface immediately implant in situ repair,in the transition period,the full realization of implant tooth and the authenticity of natural reproduction.
