Subregion can not be looked at straight, plantation Path error easily occur, cause various postoperative complications.
It can not be implanted into the patient of general planting body for labial teeth area residue bone amount wretched insufficiency, do not meet cheekbone plantation
Classical art formula indication.The scholars such as Bothur propose that unilateral cheekbone is implanted into the feasibility of more pieces of planting bodies, and respectively at bilateral cheekbone
Bone is respectively implanted into 2 pieces and 3 pieces of planting bodies, then proposes that bilateral malar reduction is respectively implanted into the Improved approach of 2 pieces of cheekbone planting bodies
(zygomatic quad approach), also referred to as double cheekbone planting body implantations.The adaptation of the more classical art formula of the Improved approach
Disease is more extensive, can obtain more optimal implant distribution of force.But research is pointed out, when unilateral cheekbone is implanted into 2 pieces of planting bodies, more
It is excessively close to be easy to appear plantation body position, injures the important anatomy structures such as eyeball, nervus infraorbitalis blood vessel, causes serious operation concurrent

Referring to attached drawing 3, when carrying out cheekbone implant operation, if the access of cheekbone planting body implantation is sinus inner mold, elder generation is needed
Lateral wall windowing before row maxillary sinus is removed and promotes mucous membrane of maxillary sinus to avoid implantation access, then by cheekbone planting body for hole
Brill etc. arrives at cheekbone by maxillary sinus internal cavity and carries out cheekbone planting body for hole and implantation.But lack on relevant both at home and abroad at present
Jaw sinus mucosa protection instrument.
The shortcomings that existing cheekbone implant operation technology includes that implant operation path length, planting location adjoin eye socket and content
Object, nervus infraorbitalis vascular bundles, cheekbone skin of face etc., and most of region of performing the operation can not be looked at straight, plantation Path error easily occur,
Cause various postoperative complications.And cheekbone planting body is twisted shape for the screw thread of hole drill, has cutting edge, therefore plants hand in sinus inner mold cheekbone
Art causes the postoperative complications such as mucous membrane of maxillary sinus perforation or rupture for easily neighbouring mucous membrane of maxillary sinus is involved in during hole,
In the presence of the risk for damaging other neighbouring hard and soft tissues.Lack suitable maxillary sinus mucosa protection instrument both at home and abroad at present, gives art
Middle maxillary sinus mucosa is reasonably protected, and the generation of the above postoperative complication is prevented.
