Embodiment
Embodiment of the present invention is described in detail below with reference to accompanying drawings.
Dental filling can allow tooth to become attractive in appearance, and rotten decayed tooth can be all removed.Eat after dental filling and no longer get stuck between the teeth
, but unique patient may careless be exactly think mended tooth after tooth would not occur the rotten tooth that decays tooth again.In fact not
So, oral environment does not change in itself after dental filling, and this bad oral environment is that you decay tooth the root of growth.But dental filling is
Oral environment can not be changed.So the thing to have been done after tooth has been mended still pays attention to oral hygiene, brush teeth sooner or later, allow mouth
Chamber environment reaches acid-base balance, and the situation for the rotten tooth of decayed tooth so occur will greatly reduce.
Obviously, during dental filling, the filling control of filler is most important, if filling is very few, can not make up completely
Dental cavity, cause food waste extended stationary periods in dental cavity, easily cause the deterioration of patient's oral environment and cause tooth body
Lesion, if filling is excessive, it can be made troubles to the use of patient, have impact on the occlusion of lower tooth, it may be necessary to after progress
Continuous resection operation.

Wherein, the automatic pad device is mended inserts injection by the corresponding inserts volume determined the tooth on target tooth
After in hole, into fine mode, in fine mode, based on the difference between thread form and the default thread form in real time,
Continue the automatic filling of inserts, until the thread form in real time matches with the default thread form；
Wherein, second wave filter is based on the described first filtering masterplate, the second filtering masterplate and the 3rd filtering mould
Version performs filtering process to the edge enhanced images to be included with obtaining final filtering image：First using the described first filtering masterplate
Filtering process is performed to the edge enhanced images, obtains the first median filter image, reuses the second filtering masterplate pair
The first median filter image performs filtering process, obtains the second median filter image, finally using the described 3rd filtering mould
Version performs filtering process to the second median filter image, obtains final filtering image；
Wherein, the automatic pad device sends dental filling and terminates letter when the real-time thread form matches with the default thread form
Number；
Wherein, the inserts discharging speed under coarse mode is more than the inserts discharging speed under fine mode；
Packaged type light deflection device, it is connected with described image identification equipment, is carried out for the physical location based on the target tooth
It is adaptive mobile, so that obtaining patient sees oneself intraoral target tooth.
4. intelligent dental department treatment couch as claimed in claim 3, it is characterised in that also include：
Liquid crystal display, for receiving the dental filling end signal, and show prompting corresponding with the dental filling end signal
Word.
5. intelligent dental department treatment couch as claimed in claim 4, it is characterised in that：
Relative position of the described image identification equipment also based on the target serratd edge image in the final filtering image determines
The physical location of target tooth.
