In conjunction with accompanying drawing 1, following typical embodiment is given further explain.
Embodiment 1: the preparation of little tensile test specimen in the experiment of tooth dentine bonding
The enamel that mill removes the tooth bizet exposes the internal layer dentine, the adhesive surface of polishing back formation standard, and mill removes the enamel around the adhesive surface, acid etching, coating adhesive, goes up binding material, forms the dental hard tissue that comprises binding material to be cut.
Dental hard tissue is placed in the sample putting hole 7 of dental hard tissue's holder 6: when preparing little tensile test specimen, and the last transverse cross-section parallel of the xsect of dental hard tissue and rectangular cylindricality dental hard tissue holder 6.Root of the tooth is put into the foursquare sample putting hole 7 of xsect, and white gypsum is inserted in the space in the hole around the root of the tooth again, and the solid firmly back of white gypsum dental hard tissue just is fixed on the rectangular cylindricality dental hard tissue holder 6.
Rectangular cylindricality dental hard tissue holder 6 is placed on the L shaped guide table 8 in right angle, and the surface level and the vertical plane of two L shaped guide tables 8 in adjacent side and right angle are close to, and dental hard tissue to be cut is positioned at front end.The place ahead of dental hard tissue is diamond wheel cutting blade 5, and the thickness of cutting dental hard tissue is by milscale 12 controls.Regulate initial cutting position, pin is stepped on the pin of dental unit and is stepped on switch, starts mobile phone at a slow speed, promotes rectangular cylindricality dental hard tissue holder 6 and can cut dental hard tissue forward.After pin was stepped on switch, the water hose 4 that is fixed in mobile phone cut end at a slow speed can be from trend cutting part spray cooling.After once cutting is accomplished; According to set thickness; The ratchet swing handle of rotation milscale 12 is to the scale of appointment; The micrometric screw of milscale promptly promotes the L shaped guide table 8 in right angle and moves forward along guide rail 10, promotes rectangular cylindricality dental hard tissue holder 6 once more and is close to two of the L shaped guide table 8 in right angle towards preceding cutting dental hard tissue, just can form dental hard tissue's sheet of a slice consistency of thickness.Milscale 12 promotes cutting more forward, so repeats above step, can be cut into continuous thin slice to dental hard tissue.Rectangular cylindricality dental hard tissue holder 6 revolved on the L shaped guide table 8 in right angle turn 90 degrees, the ratchet swing handle that repeats to rotate milscale 12 more successively promotes certain thickness forward, promote the cutting step that rectangular cylindricality dental hard tissue holder 6 cuts dental hard tissue forward again can cut into column with dental hard tissue.
The precision of milscale is 0.01mm, and the handset capability at a slow speed that dental unit is equipped with is stable, is equipped with the slim diamond wheel cutting blade of reliable quality, in the former experiments preparation, can prepare dental hard tissue's thin slice of the above thickness of 0.1mm.Requirement according to little tensile test specimen; The column test specimen xsect that cuts into is about 0.9 * 0.9mm; And the rectangular cylindricality dental hard tissue holder 6 that only needs to be fixed with dental hard tissue to be cut revolves on the L shaped guide table 8 in right angle and turn 90 degrees, and can accomplish the cutting of the little tensile test specimen of column.A general tooth required clipping time is 3 ~ 5 minutes, and importantly rectangular cylindricality dental hard tissue holder 6 can have a plurality ofly, can carry out the cutting of a plurality of hard tooth tissues continuously, and work efficiency has obtained effective raising like this.
Embodiment 2: the hard tooth tissue preparation of sections
The fixed placement of hard tooth tissue is with embodiment 1, and the cutting of tooth is also identical with embodiment 1, different need not when being dicing sheet rectangular cylindricality dental hard tissue holder 6 revolved to turn 90 degrees to cut.The direction of tooth long axis of body when specifically needing which part of incisor tooth can regulate root of the tooth and put into sample putting hole 7.The thickness of cutting is controlled by milscale.Can prepare dental hard tissue's thin slice of the above thickness of 0.1mm.
Embodiment 3: a kind of improved form
It mainly is the position of the sample putting hole 7 of rectangular cylindricality dental hard tissue holder 6.The sample putting hole 7 of embodiment 1 and embodiment 2 all is arranged on the last xsect of rectangular cylindricality dental hard tissue holder 6.Dental hard tissue all is placed into sample putting hole 7 with root of the tooth and fills up the space with white gypsum again and fix.Improved form is sample putting hole 7 design on the side of rectangular cylindricality dental hard tissue holder 6, and rectangular cylindricality dental hard tissue holder 6 is placed constant on the L shaped guide table 8 in right angle.Dental hard tissue still is placed into root of the tooth and fills up the space with white gypsum again in the sample putting hole and fix.In when cutting, dental hard tissue is positioned at side but not the front end of dental hard tissue's stationary installation 7, and the tooth long axis of body is vertical with the cut direction of carborundum grinding wheel cutting blade, so just can carry out transverse cuts to dental hard tissue.
