Abstract
The utility model discloses a tooth restoration and implantation body. The tooth restoration and implantation body comprises a top part 1, a neck part 2, a shoulder 3 and a body part 4 from top to bottom; the neck part 2, the shoulder 3 and the upper part of the body part 4 are coaxial rotary structures; the upper part of the body part 4 is provided with a hydroxyapatite filling part 5 which traverses and punches through; and the lower part of the body part 4 is provided with one or multiple long and thin poles 7 which are uniformly distributed, and the long and thin poles 7 are completely inserted into a porous tantalum structure 6 in a shape matched with the long and thin poles. The tooth restoration and implantation body of the structure fully plays respective performance advantages of three materials, namely zirconium oxide, hydroxyapatite and porous tantalum, so that the spatial form of the new bone is better, both aesthetics and practicability are considered, rejection reaction and postoperation discomfortableness are reduced, mechanical property and biocompatibility of the structure are integrally enhanced, and operation effect is better.
Description
Technical field
This utility model relates to a kind of tooth and repairs implantation body, relates in particular to all good, attractive in appearance and practical tooth reparation implantation bodys that has concurrently of little, the newborn sclerotin spatial shape of excellent, human body sense of discomfort of a kind of mechanical property and biocompatibility.
Background technology
Tooth reparation implantation body is the critical component in the anodontia prothesis.Traditional anodontia prothesis is that artificial tooth is fixed on the healthy abutment with snap ring or artificial crown, to recover masticatory function.Tooth plantation reparation refers to that the implantation body of the class root of the tooth that will be made by artificial material implants the restorative procedure in exodontia nest or the artificial tooth's nest.It is by making denture prosthesis on tooth root planting body top recovering the anatomic form of missing tooth, and stress is directly conducted and is distributed to jawbone via the tooth root planting body, thereby obtains masticatory function.Tooth plantation recovery technique relates to the multidisciplinary fields such as material science, life sciences, stomatology, bionics and engineering, is the embodiment of the comprehensive scientific and technological level of stomatology.Tooth is repaired the material of implantation body mainly can select ceramic material and metal material.Ceramic material is compared with metal material, has the advantages such as good biocompatibility, guiding skeletonization, color and luster and natural tooth approach, and becomes a focus of in recent years biomaterial development.But also there is very large shortcoming in ceramic material, and is on the low side such as mechanical strength, fragility is large, processability is not good enough etc.Ceramic material can be divided three classes by biological property: the first, and bio-inert ceramic is such as monocrystalline and polycrystal alumina, zirconium oxide etc.; The second, bioactive ceramics take hydroxyapatite, glass ceramics etc. as main representative, has the effect of Guided Bone Regeneration; The 3rd, the biodegradation pottery such as tricalcium phosphate, bio-vitric etc., self will be degraded in Guided Bone Regeneration, and be replaced by area of new bone, mainly as the bone filler.In addition, ceramic material can with the metal material compound use, can bring into play the separately advantage of bi-material, realize Performance optimization.
The utility model content
In view of the foregoing defects the prior art has, this utility model aim to provide a kind of mechanical property and biocompatibility all good, the attractive in appearance and practical tooth that has concurrently of little, the newborn sclerotin spatial shape of excellent, human body sense of discomfort repair implantation body.
To achieve these goals, this utility model by the following technical solutions: tooth is repaired implantation body and is divided into top, cervical region, shoulder and body from top to bottom; Described cervical region, shoulder and body top are the coaxial rotating structure; Described body top is provided with the hydroxyapatite that traverses break-through and fills the position; Described body bottom is equally distributed one to multiple elongate rod, in the porous tantalum structure that the complete inserted-shape of described elongate rod is complementary with it.
As the improvement to the technical program, described elongate rod quantity is three.
As the improvement to the technical program, described hydroxyapatite is filled the position and is positioned at the following 0.5-1mm of described shoulder place, described hydroxyapatite is filled the square hole shape of position for connecting, and the pore cross-section width accounts for 1/3rd of described body upper diameter, and length is 1.5-2mm.
Compared with the prior art, this utility model is owing to adopted technique scheme, zirconium oxide, hydroxyapatite and three kinds of materials of porous tantalum feature performance benefit have separately been given full play to, make the spatial shape of newborn sclerotin even more ideal, taken into account attractive in appearance and practical, reduced rejection and postoperative discomfort sense, Integral lifting mechanical property and the biocompatibility of structure, make the operation effect even more ideal.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is P-P direction cutaway view.
Among the figure: 1 top, 2 cervical regions, 3 shoulders, 4 bodies, 5 hydroxyapatite are filled position, 6 porous tantalum structures, 7 elongate rod.
The specific embodiment
Below by embodiment this utility model is carried out concrete description; be necessary to be pointed out that at this following examples only are used for this utility model is further detailed; can not be interpreted as the restriction to this utility model protection domain, those skilled in the art can make some nonessential improvement and adjustment to this utility model according to foregoing.
Embodiment: a kind of tooth is repaired implantation body, and such as Fig. 1-shown in Figure 2, described tooth is repaired implantation body and is divided into top 1, cervical region 2, shoulder 3 and body 4 from top to bottom.Described cervical region 2, shoulder 3 and body 4 tops are the coaxial rotating structure.Described body 4 tops are provided with the hydroxyapatite that traverses break-through and fill position 5.Described body 4 bottoms are equally distributed one to multiple elongate rod 7, in the porous tantalum structure 6 that described elongate rod 7 complete inserted-shapes are complementary with it.
For stabilized structure, be convenient to assembling, described elongate rod 7 preferred three.
In order to optimize structure, described hydroxyapatite is filled position 5 and is positioned at described shoulder 3 following 0.5-1mm places, described hydroxyapatite is filled the square hole shape of position 5 for connecting, and the pore cross-section width accounts for 1/3rd of described body 4 upper diameter, and length is 1.5-2mm.
Tooth is repaired implantation body and is made by zirconium oxide.The zirconium oxide porcelain piece need to just can become after high-temperature calcination and has required mechanical property and the finished product of biological safety, carries out polish by accurate engraving machine again.Hydroxyapatite and human body hard tissue chemical constituent and structure are very approximate, are desirable hard tissue substituting materials, are the main inorganic composition of vertebrates bone and tooth, through evidence obvious bone conduction effect are arranged.Behind the Hydroxapatite implant human body, under the effect of body fluid, Partial digestion can occur, element calcium and phosphorus that the tissue of dissociating is necessary, and by tissue absorption, utilization, the tissue that growth makes new advances, thus the tissue of making and tooth are repaired the good combination of implantation body's generation, can obviously improve tooth and repair the biocompatibility of implantation body, help to promote repairing effect.The porous tantalum structure has played the effect of guiding and hold bone tissue growth equally, has further improved the biocompatibility of structure, has reduced simultaneously rejection and postoperative discomfort sense, has strengthened surgical effect.
