Abstract
The utility model discloses a kind of tent screws of jawbone bone grafting, particularly belong to medical instruments field, including ontology, the ontology includes the thread segment screwed in jawbone and fixes bone meal being coated on bone defect position and supporting the disk for maintaining bone grafting space, and the end of the disk and screw is mutually fixed；The side that the disk is contacted with bone meal is arc-shaped.In the present invention, the thread segment of tent screw is being screwed in the two sides of dental implant and bone meal is filled full bone defect position by medical staff, so that disk firmly wraps bone meal, to prevent bone meal from spreading to dental implant two sides, the space for maintaining bone meal skeletonization to need can be supported simultaneously, it avoids collapsing, and the aperture on disk guarantees the blood supply of bone meal under tent again.The patient of part jawbone serious absorption needs to open up the second art area, and autologous bone is taken to do onlay bone grafting, some patients can be made to exempt the pain for taking autologous bone to carry out onlay bone grafting using tent screw.
Description
Technical field
The utility model belongs to medical instruments field, specially a kind of tent screw of jawbone bone grafting.
Background technique
Tent bone graft (Tenting Technique) is originated from Guided Bone Regeneration technology.Tent bone graft is according to it
Supporter can substantially be divided into following several art formulas: tent screw technology, autogenous bone tent technology and planting body account again
Paulin support technology.Restore bone defect area by being implanted into planting body, screw or fixed autogenous bone block in bone defect bone wall
The height and width profile of domain alveolar bone after filling bone-grafting material, and are conducive to maintain the height and width in bone grafting region, meet
Condition required for bone defect is rebuild, improves final skeletonization effect.
It is specific as follows however, there are shortcomings for the above method while generally using: 1, existing tent peg its
The bone meal area that can be coated and fixed is less, and when doing speech or chew, bone meal is easily easy to planting body patient
Two sides diffusion does not still have fixed bone meal and maintains the effect in bone grafting space.2, need to open up if being derived from body bone block
Two art areas, the wound and psychological pressure that patient bears are bigger.
Utility model content
The utility model provides a kind of tent screw of jawbone bone grafting, which has the area of cladding bone meal
The advantages of greatly and preventing bone meal from spreading to edge, while supporting the space for maintaining bone meal skeletonization to need.
To achieve the above object, the utility model provides the following technical solutions:
A kind of tent screw of jawbone bone grafting, including ontology, the ontology include screw in jawbone in thread segment and
By the fixed disk for being coated on bone defect position of bone meal, the end of the disk and thread segment is mutually fixed；The disk and bone meal
The side of contact is arc-shaped.
Preferably, the thread segment lateral wall is equipped with screw thread.
Preferably, the disk is equipped with the blood supply hole for penetrating into bone meal for blood.
Preferably, be equipped with the rotation forced section for facilitating medical staff thread segment to be screwed in jawbone in the middle part of the disk,
Correspondingly, the ontology further includes rotating handle, and the end of the rotating handle is adapted with rotation forced section.
Preferably, being equipped with fixing groove in the middle part of the disk, the rotation force part is in the slot bottom of fixing groove.
Preferably, the cross section of the rotation forced section is hexagonal, correspondingly, the end of the rotating handle is equipped with
The cross section of locating slot, the locating slot is hexagonal.
Preferably, the rotation forced section is the groove in " ten " type, correspondingly, the end of the rotating handle is equipped with
Protrusion compatible with groove, the protrusion are also in " ten " type.
Preferably, the edge of the disk is equipped with the fixation extension being bonded with bone defect circumference.
The utility model has the following beneficial effects:
In the present invention, the thread segment of tent screw can be screwed in the two sides of dental implant by medical staff, by bone meal
After filling full bone defect position, so that disk firmly wraps bone meal, thus prevent bone meal from spreading to dental implant two sides,
And space and the form in bone grafting region are maintained, in order to avoid influence the effect of skeletonization in future and the firmness of dental implant.Due to circle
The side that disk is contacted with bone meal is arc-shaped, so that bone meal, after skeletonization, shape is adapted with the shape of alveolar bone, more beautiful
Comfortably.
