The treatment of application this utility model intelligence gear division repairing and treating instrument has two kinds of modes:
First first kind of way does 3D digital scan to patient's denture, and in computer, tooth volume data to be prepared is arranged as requested, then enter data in the computer of intelligent gear division repairing and treating instrument and store, this two number is reportedly defeated by processing factory simultaneously, skilled worker master worker can produce predetermined dummy (ceramic crown or bridge) in advance according to above data, return after clinician wait the dummy of making (ceramic crown or bridge), allow again patient be located in intelligent gear division repairing and treating instrument, in patient oral cavity, bring special tooth jaw maintenance and protector into and fixed, then bore tooth body is prepared to cutting by the turbine on computer operation intelligence gear division repairing and treating instrument by the medical practitioner through training, preparation is worn at once into the bonding dummy of making in advance (ceramic crown or bridge) after having cut,
The second way, doctor first produces die and on die, records Gypsum Fibrosum in patient's mouth with silicone rubber pallet, after Gypsum Fibrosum is firmly solid, on plaster model, cut polishing to suffering from tooth again, after having prepared, be transferred to processing factory by plaster model noctovisor scan and by data storing, dummy (ceramic crown or bridge) returns to hospital after carrying out, allow again patient be located in the intelligent gear division repairing and treating instrument of gear division essence, in patient oral cavity, bring special tooth jaw maintenance and protector into and fixed, then bore tooth body is prepared to cutting by the turbine on computer operation intelligence gear division repairing and treating instrument by the medical practitioner through training, preparation is worn at once into the bonding dummy of making in advance (ceramic crown or bridge) after having cut, the tooth shape standard of preparing thus, limit is clear, in place accurately and the used time of short duration, improve to greatest extent the closely connected property of dummy, steadiness, durability, comfortableness, aesthetic property, really accomplish accurate laminating.
Specific as follows to application of the present utility model:
As shown in Fig. 1-Fig. 9, patient end is seated on the treatment seat before head maintenance support, bumper blocks both shoulders, both hands hold the handrail, upper body is straight and upright, lower chin is put in 26 places, lower chin position of Skull rest, forehead is close to forehead baffle plate 27 and is magnified mouth, gag is put into mouth props up lip, after the groove up and down of interlock pallet is put into plastic silical gel, bring strong tooth district, rear flank, oral cavity into and advise patient to sting tightly, after within 2 minutes, silicone rubber is firmly solid, upper and lower dentition has just been fixed, now, with the interlock pallet of silicone rubber can repeated multiple timesly from oral cavity, take out wear into, but can not change the position relationship of upper and lower dentition, the interlock pallet that interlock pallet is fixed on to Skull rest extends handle mounting groove 25 places and is screwed by thimble screw 24, now, head and tooth close and have all been fixed on Skull rest, and become as a whole with whole treatment chair, feldsher stands in patient's Ipsilateral one side, it is scarce limit one side of Skull rest, use and pull open Ipsilateral bicker with the special mouth mirror of inhaling saliva function and shelter from buccal mucosa, and responsible suction saliva, then, the turbine being fixed in five axis robot is bored to the relevant position of aiming at trouble tooth, machine, turbine bores and will cut polishing to suffering from tooth according to the program of prior setting, taking about 1-2 minute completes.Doctor monitors each link in oral cavity in real time by computer screen.
Interlock pallet in figure, Main Function is applicable to upper lower tooth jaw to fix, this interlock pallet is hollow type, miniature LED lamp and minisize pick-up head all can reach in oral cavity by the prolongation handle of interlock pallet, after being finished, can taking out respectively and carry out disinfection, two lines of soft tissue protection alarm, one end is connected on interlock pallet, the other end is connected in air impeller and bores, by potential difference principle, in the time that touching mucosa soft tissue, turbine drill point can make soft tissue protection alarm clock ring lamp bright, the other feldsher of chair can more clearly observe the trickle situation in oral cavity, and can in time five axis robot and turbine brill be closed down by foot switch 20, risk is dropped to minimum, and accomplish completely controlled.Skull rest and lifting seat are all fixed on treatment seat base, can adjust up and down height, and repairing and treating chair and digital control turbine rig are an entirety.
While using this equipment treatment, needs of patients comes and goes twice, hospital
Patient comes hospital for the first time, first has doctor after patient oral cavity routine is produced die, can leave hospital with silicone rubber impression pallet, without doing other processing.Doctor will record Gypsum Fibrosum on the die of producing subsequently, after Gypsum Fibrosum is firmly solid, on plaster model, will suffer from again tooth polishing preparation molding, then it be put into scanning and scan mutually and scan-data is stored into the computer of intelligent gear division repairing and treating instrument, be transferred to processing factory simultaneously.Processing factory goes out after dummy (ceramic crown or bridge) according to the data creating of receiving, then it is returned to hospital.
Patient comes hospital for the second time, allow patient be sitting on treatment chair, first inner sleeve 19 is put into the hollow position in interlock pallet, again silicone rubber is filled in the groove of both sides and bring in patient's mouth, after 2 minutes silicone rubber is firmly solid, pallet is taken out, again inner sleeve is taken out from pallet, the unnecessary silicone rubber of finishing tray edge, allow patient's forehead by steady 27, lower chin is placed under head center rest on chin position 26, one-sided silicone rubber interlock pallet is answered in tape entry and sting tight, bring elastic opening device and gear hyoplastron 19 into, and interlock pallet prolongation handle 18 is fixed on the interlock pallet prolongation handle mounting groove 25 of Skull rest, insert 23 and tighten by 24 screws, allow patient's both hands patient's handrail 22 of holding with a firm grip, the steady chain feet supporting plate 31 of bi-pedal both legs step up seat, keep health comfortable and stable.Now, patient's upper and lower dentition has been firmly fixed on Skull rest.The various devices of doctor's detailed inspection all oral cavity security protection appropriate errorless after; can start intelligent dental drill by computer and carry out cutting in mouth to suffering from tooth; and by the connected computer screen observation panel chamber inner case of looking over one's shoulder; in the time that dental drill touches intraoral mucosa; soft tissue protection alarm device sends the tinkle of bells and red light alarm immediately; puma manipulator and dental drill also stop operating automatically, and safety is fully guaranteed.Can will make in advance after tooth preparation completes ready-made dummy wear into and permanent adhesive.Do not need to adjust and reform, patient can put on the confident Go out of Hospital of brand-new tooth immediately.
This process used time is of short duration, and patient is comfortable, and preparation precisely, is worn into smoothly, once in place, firmly closely connected, has increased patient's comfort level, has reduced to greatest extent the dummy Probability of inflammation around, has fully extended the reservation time limit of suffering from tooth.
The foregoing description of this utility model embodiment, comprises the content of describing in summary, is not intended to exhaustive or utility model is restricted in precise forms disclosed herein.Specific embodiment described herein and for example only for explanation, and, according to understanding and the understanding of being familiar with correlative technology field personnel, can in this utility model spirit and scope, carry out various equivalences and improve meeting, as pointed out, can, according to the foregoing description of this utility model embodiment, this utility model is made to this type of and improve, and these improvement will be encompassed in spirit and scope of the present utility model.
