Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail, and the explanation of the invention is not limited.
Promote that resin infiltrates a device for tooth structure inside, comprising:
Resinoid bond memory, storage has resinoid bond pre-polymerization granule or resinoid bond colloid;
Gas pressurized injection unit, produce gases at high pressure through resinoid bond memory, spray from nozzle;
When gases at high pressure spray from nozzle, carry the resinoid bond pre-polymerization granule in resinoid bond memory or resinoid bond colloid, be ejected into around tooth structure to be repaired.
Specifically as shown in Figure 1; resinoid bond memory 2 internal memory contain resinoid bond pre-polymerization granule or resinoid bond colloid; the outlet of resinoid bond memory 2 is provided with through hole or the screen cloth 3 of considering hole; when the gases at high pressure of gas pressurized injection unit 1 generation are through resinoid bond memory 2; gases at high pressure carry resinoid bond pre-polymerization granule in resinoid bond memory or resinoid bond colloid; when being ejected into tooth structure to be repaired from nozzle 4, certain pressure will be applied.Be aided with certain external force when bonding agent permeates to tooth structure like this, impel bonding agent be seeped into tooth structure more deep layer, be combined with tooth structure tightr.
Utilize the promotion resin of this device to infiltrate the method for tooth structure inside, comprise following operation:
To the bonding agent inject high pressure gas being coated in dental surface;
Or will the spraying high-pressure gas of resinoid bond pre-polymerization granule or resinoid bond colloid be carried to dental surface;
Described spraying high-pressure gas is to the pressure applying 0.5Mpa ~ 5.0Mpa during dental surface, and injecting time is 5 ~ 30s.
Further, described gases at high pressure and dental surface are 30 ~ 90 degree.
