Abstract
The invention provides a method for producing a prosthesis, which adopts the computer-aided manufacturing (CAD/CAM) technology and the rapid prototyping technology for producing the prosthesis. The usage of the method can very accurately obtain the craniofacial facial data of patients; according to the data, the prosthesis, which can perfectly attach the defected part of patients and is more close to the original appearance of patients, can be designed.
Description
Technical field
The present invention relates to the recovery technique of cranium jaw face after damaged, described reparation is meant selects to utilize prosthesis reparation.The present invention be more particularly directed to a kind of method of making prosthesis.
Background technology
The cranium jaw that causes owing to reasons such as tumor resection or wounds facial damaged be very common, sometimes use surgical method and utilize that this class of autologous tissue's reconstruction is damaged to be difficult to obtain ideal effect, even can't carry out, at this moment, can select to utilize prosthesis reparation.
The congenital defect of cranium jaw face, wound, malignant tumor postoperative deformity are present in the face of representing individual characteristics, have destroyed its aesthetic conceptions and function thereof fully.Though damaged size, function.Defective attractive in appearance all can be brought serious mental burden to the patient, and its misery and feeling of despair are that healthy person is unthinkable.
In recent years, surgical technic, especially microsurgery has been obtained marked improvement, to these tissue defects patient's aesthstic method for reconstructing, the Reconstruction of various transfer of skin flap is arranged, but it is still very difficult to recover the complicated like this structure of face, can not satisfy patient's needs, repairing effect sometimes can not be satisfactory.The various prosthesises that use artificial material also are reparation means commonly used clinically always, once there were many kinds of materials to be used to make prosthesis, as metal, alloy, pottery, wax, resin and rubber etc., the sixties in 20th century, silicon materials are used for prosthesis to be made, after this, the use of other materials has just reduced, for the progress of investigation of materials, make prosthesis tangible improvement all arranged at aspects such as processing technology and colors, make prosthesis in the recovery of attractive in appearance and function, all make us satisfied.
Compare with the surgical reconstruction reparation, the prosthesis reparation does not need its hetero-organization for the district basically, more coordinates than surgical repair sometimes after reparation is finished, and prosthesis has the following advantages:
One, do not have new surgery damage, the prosthesis repair deficiency seldom need be at patient's tissue on one's body for the district.
Two, after rebuilding repairing failure, autograft can utilize prosthesis to remedy.
Three, can recover complicated form, can carry out the color adjustment, rebuild to repair with autograft and compare, Sihe is true to nature mutually on form and color for prosthesis.
Four, be suitable for auricle, nose, eye, etc. organ defect or disappearance, repairing effect is good.
Five, can make again, which kind of reason no matter when prosthesis is considered to dissatisfied, can be done one and new overcome weak point.
The making flow process of tradition prosthesis, as shown in Figure 2:
One, obtain jaw facial shape model with special-purpose impression material, the conventional anhydrous gypsum that injects is made work model.
Two, after wax-pattern is finished, carry out the embedding casting, adjust, confirm to be fit to fully jaw face base station (the used device of prosthesis promptly is installed).
Three, waxiness is removed in heating fully, and medical silica-gel is adjusted to patient's the basic colour of skin, inserts silica gel in gypsum surface.
Four, about 45 minutes heated polymerizables, dummy is taken out in the cooling back fully in cold water, repairs the sharp keen edge of dummy with shears, confirms that its edge and skin adapt, and is painted thinly on transparent silica gel surface.
Five, the silica gel dummy is done post processings such as cleaning, back making.
Six, silica gel prosthesis molding.
Traditional prosthesis manufacture method artifical influence factor is many, requires the doctor that rich experience is arranged, the affirmation of need making amendment repeatedly in the manufacturing process, and the low precision of prosthesis, rough surface.
The inventor thinks, utilizes Computer-aided manufacturing (CAD/CAM) and rapid shaping technique to make prosthesis, can overcome the defective that exists in the prior art, forms new technical solution.Can predict, this method has been utilized medical image technology, 3-D view treatment technology and rapid shaping techniques such as CT, can obtain patient's cranium jaw face data very exactly, can design according to these data and to fit very perfectly with patient institute defect, shape is more approached the prosthesis of the original appearance of patient, remedied traditional prosthesis widely and made low precision, rough surface etc. are sorry.And alleviated doctor's workload significantly, the unnecessary trouble of having brought to the patient when also having avoided impression taking simultaneously.
Summary of the invention
The present invention is directed to the defective or the deficiency that exist in the prior art, a kind of method of making prosthesis is provided, adopt this method, can obtain the face data of patient's cranium jaw face very exactly, can design according to these data and to fit very perfectly with patient institute defect, shape is more approached the prosthesis of the original appearance of patient.
Technical conceive of the present invention is to utilize Computer-aided manufacturing (CAD/CAM) and rapid shaping technique to make prosthesis.
