And mechanical stability.
Background technique
Anodontia (including defect of dentition and dentition defect) is most commonly seen one of mouth disease, and it is raw to seriously affect patient
Bioplasm amount and physical and mental health.More than the 400000000 agomphosis patients in China, close to the 1/3 of whole nation population, planting body market is huge, development potentiality
It is huge.Therefore, the Dental Erosion market demand is being growing in recent years.Due to Dental implant and traditional dentures repai
(removable partial denture with fixed denture), which is compared, to be had the advantages that incomparable, and with the improvement of the quality of life, people are for planting
Enter planting body increasingly to favor, prospect of the tooth implantation system in dental care field is very wide.
For medical instrument, dental implant system, which belongs to, is chronically implanted instrument, due to implant system implant site
Tissue can not to regenerate or take out operation abnormally dangerous, therefore the implant system usage service life is very long, after the implantation just not
(unless being failed, can not function) can be taken out again.Therefore, research improves the side of dental implant system stability
Method, the long-time stability for improving implant system are particularly significant.
Synosteosis theory has been widely accepted and has been applied to clinic, and planting body implantation is exactly that will well tie with osteocyte
In the metal implants body implantation edentulous region mandibular of conjunction, it is combined, is formed with bone tissue through planting body after a period of time
One entirety.Good synosteosis can enable implant system bear huge bite force, and can transfer loads to plantation
In body and bone tissue, restore tooth function to greatest extent.Implant operation early period planting body primary stability and later period tooth
The stability of hat, base station and planting body connection is the key that the final success of tooth-implanting operation.
Currently, the basic structure of most of dental implant system includes planting body, base station, connecting screw and corona.Plantation

Top, the part for being pierced by gum and being exposed in oral cavity are the key structures connected between upper crown and lower part planting body；Even
Connecing screw is the part for connecting base station and planting body.Developer is usually by implant system biomechanical analysis, tired
Labor life experiment and Optimal Structure Designing improve the stability of implant system.
The Biomechanical factor that generally acknowledged influence implant system repairs success rate at present has: geometry, the kind of planting body
Implant material, planting body-design of base station connection system, the dissection shape of the surface topography of planting body and surface treatment mode, jawbone
State, the biomechanics characteristic of jawbone and mode of oral occlusion etc..
In the art, process for modifying surface improve implant system it is antifatigue and in terms of play
Critical effect.Traditional surface treatment method is due to increasing an interface, and there are the risks of coating shedding；To planting body
In-situ-surface modifying is carried out, the key technology for improving implant system stability is increasingly becoming.
Due to individual difference, everyone oral condition and bone is horizontal different, for example Asian is than occidentals jawbone
Narrow, situation is sufficiently complex, and planting body size is more single, and the plantation of suitable size can not be implanted into according to different situations
Body.Therefore, with greater need for the narrow diameter planting body of special requirement and short planting body, be conducive to be processed into the plantation for being suitable for compatriots' feature
System system, to expand the adaptability of plantation, improve long term success.
Planting body can be made to have self tapping performance, nothing studies have found that adding self tapping slot outside planting body in the art
Tapping step is needed, can be threaded directly into connecting hole, Bone condensing effect can be generated to a certain extent.Currently, some planting bodies
The structure of self tapping slot is mostly with vertical, skewed slot is common.It is analyzed from amechanical angle, vertical self tapping slot is when screwing in connecting hole, vertically
Notch building up by welding connecting hole power concentrate on one wire, have very big cutting resistance, it is easy to generate bone injury.And
The bone bits that vertical self tapping slot generates during self tapping can not be discharged or accommodate, so that vertical notch end face corner answers
Power is concentrated, and is easy to produce micro-crack at planting body fluting.The self tapping slot of skewed slot is easier to cut than vertical self tapping slot, but can only
Planting body for elongate cylinder structure.
Existing base station is connect with planting body using quadrangle, hexagonal and illiciumverum, which is prone to micro- rotation, i.e.,
Make to fasten using connecting screw, also not can avoid subtle rotation.Micro- rotation is so that planting body locally generates stress and concentrates, when long
Between stress accumulation, it is easy to cause the damage and deformation of junction.
In the art, some planting bodies are cylindricalitys, are not easy to the implantation of implant system；One outside some planting bodies
As use single screw thread so that planting body stress concentration point in alveolar bone and soft tissue interface, is not easy to guarantee the steady of implant system
It is qualitative.
Tumer in 1956 et al. proposes that the concept of finite element obtains satisfaction by analyzing practical structures discretization
The approximation of engineering precision.And finite element method is applied to Medical orthopaedic research earliest, starts from spinal biomechanics.Tens
It is widely applied over year in solution biomechanical issues, 1976, Weinstein et al. was for the first time to department of stomatology Medical treatment device
The finite element analysis of tool, hereafter finite element is just in the field important role, the especially planform of these implant systems
And material selection be not only related to the mechanical properties such as the mechanical stability, survivability of instrument itself, be also relate to it is related
The problems such as biocompatibility of tissue.Therefore finite element method becomes the powerful for instructing implant system structure to design, from
And the Curve guide impeller for implant system structure provides theoretical foundation.
