Background technology
Dental implant operation puts into dental bed implantation body exactly, after waiting implantation body and dental bed length jail, then in implantation body
On connect a porcelain tooth true to nature, be properly termed as emulate tooth.
Dental implant operation has a lot of advantages, and the tooth as healthy can be fully retained, it is not necessary to grind off neighbouring healthy
Tooth；Firm artificial tooth root can increase comfort, has good masticatory force, and sensation is as oneself born tooth；Plantation
It may happen that come off and cause the danger blocking trachea or esophagus when the stability of tooth will not be at table as normal activity artificial tooth or speak
Danger；Implant tooth can have the longest life-span；General as natural teeth, when speaking, facial expression is as the most natural,
Increase your self-confidence.
But, the different people requirement when carrying out planting tooth is different, to some complicated cases, especially at upper volume
In the case of bone height deficiency at the bottom of hole, it is desirable to when bone height is less than 5mm, need to window from upper sinus frontalis buccal wall, by upper sinus frontalis film
Buccal wall and lower wall and part palate sidewall and maxillary sinus membrance separation, then bone alternate material is inserted in cavity to expect the later stage
Skeletonization.
Because technique is higher to the surgery fundamental importance of doctor, major part odontologist is because of face amount surgical technic level not
Foot, adds and does not has one safe and reliable, fast, it is easy to the outer of operation carries instrument, so always hoping promoting operation outside upper sinus frontalis
And step back, interior lifting is done in blind operation of would rather taking a risk, and is not the most bold enough to do outer lifting.
Domestic have many similar instruments, and mainly based on Korea S's import instrument, but each instrument all exists some not
Foot, does not has a kind of instrument to can solve the problem that the cheek side seam wall type that various oral cavity patient is different, it is impossible to allow dentist trust veritably, depend on
Rely.
