Metallic substrates 2-2 is arranged on the both sides (or middle) of metal crane span structure 2, and pontic support 2-1 is arranged between metallic substrates 2-2, and it is an integral body that pontic support 2-1 connects each metallic substrates 2-2.
Apolegamy base station 1 of the present utility model: the front non-fenestration method for marking of apolegamy base station 1 is produced plantation and repaired die and pour into super hard gypsum model; The standard of apolegamy base station 1: on plaster model according to implant system, stress, occlusogingival distance from selecting the base station of suitable type, diameter, height with gingiva thickness, wear gum height and be advisable to guarantee that base station edge is positioned on gingiva cuff edge, so that the inspection of metal crane span structure 2 marginal fits;
The making of metal crane span structure 2: on the plaster model of having matched base station 1, make the fusible pattern of metal crane span structure 2, with cobalt chromium porcelain alloy cast metal crane span structure, polishing adjust and the base station 1 that makes it on model closely sealed; On this model, with direct restorative acrylic resin, make plastics corpusculum in place in addition.In place in plastics corpusculum guiding in place base station 1 Kou Nei implantation body, add torque 30Ncm, remove corpusculum in place;
In mouthful, try metal crane span structure 2 on: metal crane span structure 2 is located in to a mouthful interior base station 1, and reaches substantially closely sealed.Metal crane span structure 2 and base station 1 reach substantially closely sealed standard:
(1) detect metal crane span structure 2 edges and base station 1 junction without obviously outstanding protruding, depression and damaged;
(2) during in place in 2 mouthfuls of metal crane span structures and dislocation without obvious resistance;
(3) metal crane span structure 2 is located in rear the stablizing of base station 1 and spends without moving;
(4) metal crane span structure 2 is located in after mouthful interior base station 1, and lens examination base station 1 is with metal crane span structure 2 junction edges without clear gap, and maximum is connected gap≤200 μ m;
Through above standard inspection, if any do not meet in above-mentioned four inspections any one, illustrate that metal crane span structure 2 and base station 1 do not reach substantially closely sealed, need again produce plantation reparation die, making metal crane span structure 2.
Shift completing of Moulage device: metal crane span structure 2 base station 1 in mouth try on reach substantially closely sealed after, with 3M glass ion bonding agent, metal crane span structure 2 is adhered on mouthful interior base station 1, form base station-metal crane span structure aggregation, using this as the transfer device of planting fixed bridge die, produce plantation fixed bridge and repair accurate die.
Operation principle of the present utility model: base station 1 is finished product, obtains planting apolegamy on the plaster model of repairing; Metal crane span structure 2 is that make wax pattern on the plaster model of being furnished with base station 1 after, lost-wax casting forms, and keeps closely sealed with base station 1; In two kinds of structure Kou Nei implantation bodys, by the bonding formation aggregation of bonding agent, base station-metal crane span structure die transfer device, repairs die transfer device as plantation fixed bridge.
Base station 1 is located in implantation body's (or alternative body) hat side, by center screw and implantation body's (or alternative body), is and is rigidly connected; Upper end is positioned at the metallic substrates 2-2 of metal crane span structure 2, chemical by mechanical constraint and bonding agent is bonding to be and to be rigidly connected with it, metallic substrates 2-2 is the rigid unitary connecting into by pontic support 2-1, between Ji Duoke implantation body (or alternative body), by this transfer device, realized and being rigidly connected, to guarantee to plant in transfer operation process, kept the relative position between implantation body constant.
This utility model is transferred to the implantation body's position relationship in mouth outside mouth as conducting wire rigid-connecting device, the transfer device of high-flexural strength, impression material be can eliminate and the impact bringing, the distortion of opposing model plaster are out of shape, avoid the loosening displacement between connecting device, thereby improve the accuracy that plantation fixed bridge is repaired die;
The apolegamy of base station 1 and in place.Base station 1 is to realize rigidly connected important structure between metal crane span structure 2 and implantation body's (or plantation substitutes body).Base station 1 lower end is connected (or being connected with the alternative body of plantation outside mouth) by center screw in mouth with implantation body; Upper end is connected with the metallic substrates 2-2 of metal crane span structure 2 by the bonding force of mechanical constraint and bonding agent.The front non-fenestration method for marking of apolegamy base station 1 is produced plantation and is repaired die and pour into super hard gypsum model.The standard of apolegamy base station 1: on plaster model according to implant system, stress, occlusogingival distance from selecting the base station of suitable type, diameter, height with gingiva thickness, wear gum height and be advisable to guarantee that base station 1 edge is positioned on gingiva cuff edge, so that the inspection of metal crane span structure 2 marginal fits.When in place in 1 mouthful of base station for guarantee with mouthful external model on the concordance of base station 1 position, need make plastics corpusculum in place having matched on the mouth external model of base station, correctly in place in the mouth of guiding base station.
The making of metal crane span structure 2 and trying on.Metal crane span structure 2 is to be formed by the good alloy of casting character (cochrome, billon) casting, comprises metallic substrates 2-2, pontic support 2-1 in function; Metallic substrates 2-2 is positioned at base station 1 upper end, and there is mechanical constraint structure (being that base station rotates without horizontal direction in metallic substrates) in 1 of base station, that base station 1 and metal crane span structure 2 are realized rigidly connected important composition, the thickness of metallic substrates 2-2 is not less than 0.5mm, edge is connected part (mouth outside on plaster model) with base station 1 closely sealed, is connected and stitches gap≤50 μ m; Pontic support 2-1 is the part of connection metal substrate in metal crane span structure 2, cross-sectional area is the bigger the better in principle, but width is no more than substrate crown, thickness is not affect interlock and not oppress gingiva (and keeping 2mm gap between gingiva) and be advisable, and metal crane span structure 2 these structures of plantation the successive winning of the number on title are not obvious; Metallic substrates 2-2 and two kinds of structures of pontic support 2-1 seamlessly transit, without obvious boundary line;
Bond layer is between metal crane span structure 2 and base station 1, by the metal crane span structure 2 of having tried on base station 1 surface adhesion and obtaining in mouth, thereby realize base station 1 and metal crane span structure 2 is rigidly connected into aggregation, base station-metal crane span structure transfer device, repairs die transfer device as plantation fixed bridge; Bond layer thickness is less, and the adaptation of base station and metal crane span structure is better, is rigidly connected also better; For bonding cement and the resin cement of metal crown class, be all chosen as bonding agent.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
