Abstract

The invention relates to a fabrication method for a dental implanting positioning and orienting guide plate. The fabrication method has the detailed steps as follows: wax teeth in coincidence with the false tooth shape are modeled by wax at the missing tooth zone of the plaster model I of a patient; the plaster with wax teeth are turnover into a total plaster model II; the insertion path of implanting screws are determined according to the positions of the teeth and the shapes of the alveolar bones; holes are bored downwards from the occlusal faces of the teeth needing to be repaired on the model II by a fissure bur to cause the holes to be communicated the whole model; the bored model II is placed in a vacuum pressed film machine to be made into a vacuum pressed film denture base which forms a tubular channel in the hollow hole; the vacuum pressed film denture base is taken down from the model II to trim; the vacuum pressed film denture base is put on the model I, the bottom part of the tubular channel is trimmed to cause the lowest point to be slightly higher than the model I, and the trimmed vacuum pressed film denture base is the dental implanting positioning and orienting guide plate. The positions and the direction of the implanting screws can be determined before operation by the fabrication method, and the implanting screws can be accurately moved to the oral cavity of the patient in the operation.

Description

The manufacture method of guide plate for growing positioning and orientating of dental

Technical field

The present invention relates to a kind of manufacture method of guide plate for growing positioning and orientating of dental.

Background technology

In the dentistry implant operation, the positioning guide plate of making before operation can help the doctor roughly to determine the position that the plantation nail is implanted in operation.But this guide plate can only roughly be determined to implant initial point, can not determine that planting the nail implantation puts into direction.The direction of implanting the plantation nail can only rely on the doctor to pass through range estimation to determine that roughly this has just increased the error of operation, adjusts and reform the stability that has reduced the plantation nail putting into repeatedly.

Summary of the invention

The object of the present invention is to provide a kind of simple for productionly, can determine to plant the site, can determine to plant the manufacture method of the guide plate for growing positioning and orientating of dental of direction again.

The manufacture method of the guide plate for growing positioning and orientating of dental that the present invention proposes, concrete steps are as follows:

(1) moulds out the wax tooth 2 that meets the artificial tooth form in the edentulous region of patient's plaster model 1 with the wax heap;

(2) to turn over that mould becomes all be the model 23 of Gypsum Fibrosum to the Gypsum Fibrosum that will have a wax tooth 2, and its model base can not be too thick;

(3) determine the path of insertion that plantation is followed closely according to the position of tooth and the form of alveolar bone;

(4) close the boring that faces down with splitting the tooth that is drilled on the model 23 from the tooth of needs reparation, make hole 4 gang up whole model, the position of hole 4, diameter and direction all are consistent with the direction that the plantation that will implant is followed closely;

(5) model 23 that has openning hole is placed on making vacuum film pressing dens supporter 5 in the vacuum film pressing machine, vacuum film pressing dens supporter 5 has formed a tubular conduit 6 in hole 4 inside;

(6) take off vacuum film pressing dens supporter 5 from model 23, and the trim edge scope;

(7) vacuum film pressing dens supporter 5 is placed on the model 1, the bottom of finishing tubular conduit 6 makes it minimum point a little more than model 1, and the vacuum film pressing dens supporter 5 that trims is guide plate for growing positioning and orientating of dental;

When (8) using, the patient oral cavity is put in the guide plate for growing positioning and orientating of dental sterilization, can on alveolar bone, be planted the implantation of nail according to the direction of the tubular conduit on the guide plate for growing positioning and orientating of dental 6.

Vacuum film pressing machine that the present invention's use can be bought on the market and supporting plastic sheet.The vacuum film pressing machine will heat the plastic sheet of deliquescing, and the negative pressure by vacuum produces is attached at the shape that model surface forms tooth and soft tissue with plastic sheet.

Beneficial effect of the present invention is: can just determine the position and the direction of plantation nail before operation, and be transferred to patient's mouth exactly in operation.The press mold material has certain elasticity, can be fixed on easily on the contiguous tooth body of growing area, and the press mold material is transparent simultaneously, makes things convenient for the doctor to observe and operates.

Description of drawings

Fig. 1 is the sketch map of manufacturing process of the present invention.

Fig. 2 is a final effect sketch map of the present invention.

Number in the figure: 1 is that model one, 2 is the wax tooth, and 3 is that model two, 4 is a hole, and 5 is the vacuum film pressing dens supporter, and 6 is tubular conduit.

The specific embodiment

Further specify the present invention in conjunction with the accompanying drawings below by embodiment.

Embodiment 1: with lower-left first molar disappearance is example, specifies implementation method of the present invention.

(1) moulds out the wax tooth 2 that meets lower-left first molar form in the edentulous region of patient's plaster model 1 with the wax heap;

(3) determine the path of insertion that plantation is followed closely according to the position at first molar place, lower-left and the form of alveolar bone;

(4) be drilled in splitting that the tooth from the lower-left first molar closes the boring that faces down on the model 23, make hole 4 gang up whole model, the position of hole 4, diameter and direction all are consistent with the direction that the plantation that will implant is followed closely;

(6) take off vacuum film pressing dens supporter 5 from model 23, and the trim edge scope is to holding whole mandibular dental arch;

(7) vacuum film pressing dens supporter 5 is placed on the model 1, the bottom of finishing tubular conduit 6 makes it the height of minimum point a little more than the edentulous region mucosa of lower-left first molar on the model 1, and the vacuum film pressing dens supporter 5 that trims is guide plate for growing positioning and orientating of dental;

When (8) using,, be seated on the lower jaw denture, on alveolar bone, plant the implantation of nail according to the direction of the tubular conduit on the guide plate for growing positioning and orientating of dental 6 putting into the patient oral cavity after the guide plate for growing positioning and orientating of dental sterilization.

Claims

1, a kind of manufacture method of guide plate for growing positioning and orientating of dental is characterized in that concrete steps are as follows:

(1) moulds out the wax tooth (2) that meets the artificial tooth form in the edentulous region of patient's plaster model one (1) with the wax heap;

(2) to turn over that mould becomes all be the model two (3) of Gypsum Fibrosum to the Gypsum Fibrosum that will have a wax tooth (2);

(4) be drilled in model two (3) and go up from the tooth of the tooth of needs reparation and close the boring that faces down with splitting, make hole (4) gang up whole model, the position of hole (4), diameter and direction all are consistent with the direction that the plantation that will implant is followed closely;
