Background technology
Defect of teeth and defect of dentition are stomatologic common disease and frequently-occurring disease. Defect of teeth generally can take placement method to treat. Serious when defect of teeth, when attractive in appearance requirement that filling is difficult for successfully maybe reaching higher, should adopt the method for repairing and treating, recover form, the function and attractive in appearance of agomphosis with the dummy of manual manufacture. Conventional dummy has inlay, part-crown, veneer, complete crown and post and core crown etc. Defect of dentition refers to that the permanent teeth denture that part absence of tooth causes is imperfect, in order to recover dysfunction that defect of dentition causes and the infringement of counterpart jaw system health, conventionally adopt the method for artificial substituting material reparation to recover anatomic form and the physiological function of missing tooth. Conventional repair mode comprises fixed denture, removable partial denture, overlay dentaure, implant denture etc., wherein, fixed denture, it is the dummy of repairing one or several missing tooth in denture, link together by binding agent or the ready abutment of fixture and both sides, recover form, the function and attractive in appearance of agomphosis.
Temporary prosthesis refers to that completing front patient to final fixed restoration after the fixing tooth preparation of repairing can not freely get the provisional dummy of wearing, and comprises temporary crown, temporary transient bridge, temporary transient veneer and temporary transient inlay etc., the most common with temporary crown and bridge. Temporary crown has protection gum, provides attractive in appearance, protects dental pulp, stablizes tooth position and be beneficial to the functions such as pronunciation; simultaneously; it also can provide temporary transient masticatory function to a certain extent, also can play the effect of diagnosis or judgement in complexity reparation, for the success of formal dummy lays the first stone. The effect of above-mentioned temporary crown is: (i) the vital tooth that protection is produced is avoided the thorns such as hot and cold stimulation and acidic food. Under local anaesthesia, do tooth preparation, particularly ceramic crown bridge tooth cutting amount is large, and if do not done temporary crown protected, patient cannot normally take food, and even cause dental pulp pathology in the future; (ii) stop the abutment displacement of preparing: comprise that abutment, adjacent teeth and antagonist are closely far shifted and close to displacement, this displacement will cause being preced with bridge difficulty in place and Occlusal interference; (iii) prevent that gingival hyperplasia from growing on shoulder, be particularly positioned at person under gum for shoulder, thereby prevent from being preced with bridge difficulty in place; (iv) the abutment that protection is produced, is mainly devital tooth, avoids chewing of hard food and causes coming off of the body jackknifing of part tooth or charges; (v) prevent from being produced abutment proximal surface food impaction, and concurrent gum tissue is shunk back and inflammation thus; (vi) the temporary Guan Qiao of labial teeth makes of finished product tooth sheet, can having improved aesthetic appearance, do not affect patient's normal doings.
The preparation method of temporary crown is a lot of clinically, has direct method and the indirect method of making on diagnostic model etc. of after tooth preparation, in mouth, directly making. Conventional temporary crown material has pre-capping, methyl methacrylate plastics and acrylic resin. Now to use acrylic resin interim repair materials indirect method to introduce three kinds of methods for fabricating provisional crown of partial as example: (1) makes shaping female mold: before tooth preparation corona complete can be in mouth impression taking as shaping female mold; The excessive research model of first getting before tooth preparation of defect of teeth completes the wax pattern of final dummy on model, produces the die of wax pattern, as the shaping female mold of provisional prosthesis on model; (2) after tooth preparation, mediation acrylic resin provisional prosthesis material (LuxatempHandmix Luo Saite hand adjustment type crown and bridge material), within its working time, fill in the shaping female mold of tooth preparation tooth and around tooth preparation, shaping female mold is completely in place, stablize about 2-3 minute, in the time that dummy material becomes rubber-like, take out former; Etc. (3) several minutes, the complete polymerization of dummy material was solidified, and in shaping female mold, takes out provisional prosthesis, recontour, and polishing, forms temporary crown.
The desirable edge of temporary crown should just arrive shoulder and complete line, should not exist long, too short, blocked up, and neck edge between gapped situation, thickness is suitable, with the closely sealed tight of Tooth surface, surface be connected smooth. Long, wide retainer edge cause stimulate or edge not closely sealed, edge is not suitable for complication: marginal ginhivitis, after dummy cementation, shows as temporary crown gum edge and obtain the hyperemia of gum tissue, oedema, easy hemorrhage, pain etc.
In the time that temporary crown is won: put into the temporary crown of having made after interim repair materials is in harmonious proportion, be located in fast on preparation abutment, treat to take off before material solidifies completely, sometimes the not easy-to-use hand of single temporary crown takes off, need be by getting hat device, but the adaptation of getting hat device destructible temporary crown edge, the not closely sealed needs in temporary crown edge are rebasingd sometimes, have increased time that patient seeks medical advice and doctor's working strength. Therefore need to make a kind of instrument that can take off temporary crown and do not destroy again temporary crown edge.
