Embodiment Construction
[0030] A method for making a composite face filling prosthesis, which comprises the following steps
[0031] Step 1: Put silicone rubber into the mold cavity through the prosthesis mold for vulcanization to make silicone rubber facial filling prosthesis, including temporal filling prosthesis 1 and zygomatic filling prosthesis 2, such as Figure 1-Figure 4 As shown; the surface of the prosthesis is frosted, and the roughness is: 1-3μm;
[0032] Step 2: Cut the expanded polytetrafluoroethylene sheet with micropores on the surface into a sheet with the same shape and size as the silicone rubber-filled prosthesis;
[0033] Step 3: Dissolve medical semi-solid silicone rubber in petroleum ether solvent to make it fully dissolved, and the viscosity is 600-800cP at room temperature;
[0034] Step 4: Spread the liquid silicone rubber made in step 3 evenly on the prosthesis made in step 1, and let it dry naturally;
[0035] Step 5: Lay the bulky sheet 11 and bulky sheet 2 21 cut in ste...

Abstract
The invention discloses a manufacturing method of a composite facial filling prosthesis. The manufacturing method comprises the following steps of: step 1, vulcanizing silicone rubber in mold cavitiesthrough prosthesis molds to prepare silicone rubber facial filling prostheses, including a temporal filling prosthesis 1 and a zygomatic filling prosthesis 2, as shown in figures 1-4, wherein the roughness of the surface of the prosthesis is 1-3 microns in a frosted state, step 2, cutting an expanded polytetrafluoroethylene sheet with micropores in the surface into sheets having the same shape and size as the silicone rubber filled prosthesis; and step 3, dissolving the medical semi-solid silicone rubber in a petroleum ether solvent to fully dissolve the medical semi-solid silicone rubber, and keeping the viscosity at 600-800 cP at normal temperature. The composite facial filling prosthesis has the beneficial effects that tissue cells can grow into the composite facial filling prosthesiswith the micropores in the surface, the defects of displacement, enveloping and the like of the postoperative prosthesis due to the smooth surface of silica gel are effectively overcome, and the use effect of the facial prosthesis after shaping is improved.
Description
technical field [0001] The invention relates to the field of composite facial prosthesis production, in particular to a production method of composite facial filling prosthesis. Background technique [0002] Polytetrafluoroethylene is a polymer compound containing fluorine atoms in the main chain of the molecule. The F atoms in the PTFE molecule cover the C-C bond and the C-F bond has high bond energy and good chemical stability; since it came out in the 1960s , PTFE is widely used in industrial, medical, military and other fields because of its stable physical and chemical properties and good biocompatibility. [0003] Silicone rubber is a linear high-molecular-weight polyorganosiloxane whose main chain is composed of silicon and oxygen atoms alternately. Its unique chemical structure determines its good physiological inertness and body fluid corrosion resistance. It can be used in harsh environmental conditions. High aging resistance, excellent biocompatibility, minimal r...
