The asymmetric dental implants can be divided into two groups: namely the single type and the multi type according to the number of the designed tooth root implant; two groups: namely the straight type and the bend type according to the need of the position where a dental implant is planted; two groups: namely the single tooth type and multi tooth type according to the number of the designed dental crown; and two groups: namely the coaxial type and the preset deflection angle type according to the including angel between the tooth root and the baseline of the tooth crown; the various types mentioned above can be combined with each other to form various combined types, the asymmetric dental implants are provided with various sizes, so the operator can choose the most suitable type and size of the asymmetric dental implants according to the dissection characteristics of the planted alveolar bone of the patients.
Description
Technical field
The present invention relates to the tooth-planting field, more specifically, relate to a kind of asymmetric tooth implant of applicable jawbone anatomy form.
Background technology
Having healthy and beautiful tooth is one of embodiment of the high-quality healthy living of people, and along with development and the progress of stomatology and each related discipline technology, today, the Dental Implant technology developed into the standard restorative procedure of dentition defect gradually.The tooth implant of main flow is revolving body cylindrical thread or the taper thread endosteal implant around the axis symmetry in the world at present, for strengthening the adhesion of sclerotin and implant surface, mostly adopt the PROCESS FOR TREATMENT of alligatoring implant surface as far as possible, for example with the method for machining, in implant surface, make screw thread, stage, with the high-temperature metal spraying method to form coarse implant surface, adopt blasting method to obtain the concave-convex surface effect, method with chemical erosion improves asperity of implant surface etc., the employing of above-mentioned all processes all is intended to by the modification to implant surface pattern and roughness processing and improves surface bioactive and chew in the interlock activity the formed alternation compressive stress of implantation body with overcoming to bear within the longer time, the alternation moment of flexure, the unfavorable factors such as alternate torque, keep the firm combination between implantation body and host bone bed.But the revolving body tooth implant that this type of is symmetrical, the processing method of every surface modification still exists some shortcomings and deficiencies separately, for example:
1. the longitudinal cross-section of tooth implant can't effectively meet jawbone cheek-tongue direction or the words anatomy form to cross section, and therefore great limitation is arranged when selecting stress and length specification;
2. the cylindrical thread of symmetrical revolving body or taper thread are easily loosening under long-term alternate stress and torsional interaction;
3. the design of the revolving body of the symmetry of non-anatomical form easily causes implantation body to produce interference and the secondary untoward reaction occurs with the adjacent healthy root of the tooth after the implantable bone bed;
Summary of the invention
The asymmetric tooth implant that provides a kind of jawbone section morphology with wanting the implantation position place to match is provided the object of the invention, this asymmetric tooth implant be through to different mankind group tooth body particularly the root form data carry out induction-arrangement, set up the three-dimensional data model of statistical significance, and revised on this basis the asymmetric tooth implant of series that Integration Design becomes to have extensive degree of containing, this asymmetric tooth implant series is divided into single type and Duo Gen type according to designed root of the tooth body quantity, its root of the tooth body is according to the design that straight type and flexure type need to be arranged respectively of implantation position, be divided into single tooth form and polydonita type according to designed corona quantity, angle according to datum line between root and corona is divided into coaxial type and default deflection angle type, aforementioned all kinds can be various combined by mutually being combined to form, asymmetric tooth implant is provided with plurality of specifications and selects optimal asymmetric tooth implant type and specification so that the patient plants tooth alveolar bone place anatomical features according to the patient.Consider the demand of indivedual special cases, also can outside the form of standard series and specification, CT and the MIR data according to indivedual tooth bodies and alveolar bone directly set up this tooth body Model and use the customization of modern manufacture means fast to be applicable to individual dissection and learn the tooth implant of form to satisfy the demand in computer.
