Abstract
The utility model discloses a mucosa supporting bracket used after maxillary sinus lifting, which comprises a titanium plate fixed to the front outer side wall of an upper jaw bone and a convex pillar for lifting a maxillary sinus mucosa stripped in the maxillary sinus lifting,wherein the convex pillar is fixed to the titanium plate to form a whole body with the titanium plate. The mucosa supporting bracket used after maxillary sinus lifting can keep a space of maxillary sinus lifting without carrying out bone grafting; the lifting space is fully filled with blood; the osteogenesis potential of a maxillary sinus floor mucosa and the healing capacity of an organism are utilized to promote the forming of a new bone; unanticipated complications of absorption, immunological rejection and the like, which are generated due to the substitute material of an implanted bone, are avoided; the treatment cost of a patient is reduced.
Description
Technical field
This utility model relates to a kind of dental instruments, relates in particular to mucosa supporting bracket after a kind of Maxillary Sinus.
Background technology
Implant denture passes through the development of nearly 50 years, has become a kind of Oral Repair treatment means of maturation, and many agomphosis patients' quality of life is significantly improved and enhanced.After upper jaw backteeth district agomphosis due to the absorption of alveolar bone, loosening of sclerotin, and the gasification of maxillary sinus structure, usually cause Sinus floor can utilize bone height not enough, thereby becoming the difficult point of implant prostheses treatment. Maxillary Sinus is a kind of generally acknowledged ripe bone increment technique, and the object of Maxillary Sinus is exactly can obtain enough bone supports in order to increase after the Gu Liangshi implantation body of Sinus floor implants.1976, Tatum proposed for the first time the concept of Maxillary Sinus in Alabama plantation meeting, and Boyne in 1980 and James have proposed the Maxillary Sinus bone grafting operation through vestibule ditch otch first.Many scholars affirm and have improved this art formula subsequently.Maxillary Sinus need to be implanted various bone-grafting materials.Desirable bone substitute can promote the Osteogenic Cells field planting of bone defective region, for the generation of new bone provides support, promotes bone to rebuild, and can be used as the biotic factor carrier that stimulates osteanagenesis to repair, and biomechanical property and healing stage protection structure below etc. are provided simultaneously.For the osseous tissue substitution material of planting, mainly contain clinically at present: autologous bone, homogeneous allogenic bone, xenogenesis bone, artificial bone.Because autologous bone transplanting has osteogenesis, osteoinductive and bone conductibility simultaneously, therefore be considered to the most effective bone grafting material, " goldstandard " during osseous tissue substitutes, but the complication that autologous bone often needs to open up the second art district and produces Gong Gu district, patient is usually difficult to accept, and can not arbitrarily cut mouldingly, the shape and function of impact after more recovers.Homogeneous allogenic bone refers to that a certain individuality that derives from same germline is transplanted to another individual osseous tissue material.Homogeneous allogenic bone transplantation has been avoided the deficiency of autologous bone transplanting, for example, easily obtain, and has reduced operating time and post-operative complication etc., but with autologous bone photo ratio, still exist bone formation slowly, bone repair ability is weak and the shortcomings such as rejection of body.Bone xenograft refers to that the osseous tissue that a kind of germline is obtained is transplanted in the individuality of another germline, comprises Os Bovis seu Bubali, Os Sus domestica and Corallium Japonicum Kishinouye bone etc.Os Bovis seu Bubali is to study at present and most widely used xenogenesis bone material.Bio-Oss is a kind of cattle inorganic bone substrate of being used widely clinically, it has the chemical composition and structure similar to nature bone inanimate matter, commitment in osteanagenesis promotes osteoblastic activity, is conducive to growing into of osteoblastic migration and blood vessel.Although Bio-Oss all obtains good effect in experiment and clinical practice, but still exist to absorb slowly and the shortcoming such as shortage osteoinductive.Artificial bone is divided into single artificial bone, polyethylene artificial bone composites, tissue engineered artificial bone.Single artificial bone is of a great variety roughly can be divided into inorganic material and organic material by structure and performance, and wherein inorganic material comprises: hydroxyapatite (HA), tricalcium phosphate (TCP), bio-vitric (BG).Although artificial bone is of a great variety for bone defect repair in implant operation provides larger choice but these artificial bones all exist such-and-such deficiency, as only thering is bone conduction effect, there is no bone inductive effect, do not degrade or degradation time can not be controlled, mechanical strength not enough in vivo.The ultimate principle of polyethylene artificial bone composites is exactly that the material with bone conduction ability is prepared into cmposite artificial bone with the material with bone inducibility as somatomedin is compound.Tissue engineered artificial bone refers to principle and the method for utilizing engineering and life sciences, by the cell seeding with osteogenic activity of a certain amount of Isolation and culture to have on the artificial bone supporting material of certain space structure and or with the mutually compound formation tissue engineered artificial bone of somatomedin.In sum, various bone alternate materials always have some shortcomings part, also there is no at present a kind of desirable bone alternate material, if therefore we can not maintain the space of lifting in Maxillary Sinus by bone grafting, allow the space normal healing promoting form blood clot, utilize blood clot to contain the formation that multiple somatomedin promotes new bone in room for promotion, so just can obtain desirable Maxillary Sinus effect.
