Abstract
The present invention relates to a micro screw implant, which is provided for solving problems of alveolar bone absorption, peri-implantitis occurrence and low service life of the existing dental implant. The micro screw implant is characterized in that the micro screw implant has a cylindrical shape, and adopts symmetrical trapezoidal threads, a coarsening treatment is performed on the surface of the threads, the top of the threads is an annular groove structure, the neck portion of the implant is a smooth surface, the bottom of the implant is an arc surface shape, the implant is provided with four self-tapping grooves, and the internal of the implant is provided with a cone hole structure and a hexagonal structure, and is further provided with a standard threaded blind hole. With the present invention, bone absorption can be effectively avoided, peri-implantitis occurrence can be prevented, and a service life of the implant can be increased.
Description
Technical field
The invention belongs to the oral cavity medical apparatus field, what relate generally to is a kind of micro thread implant.
Background technology
Oral implantology is the most outstanding achievements in research of 20th century of stomatology, and its development and maturation have greatly been improved stomatologic present situation, have promoted stomatologic development.In clinical position and patient group, become the preferred option of the facial counterfeit multiple treatment of absence of tooth and oral cavity song gradually, broken through the insoluble therapeutic domain of many conventional recovery scenarios, improved patient's quality of life greatly.The direction that also will treat, reduce cost, reduce patient's wound misery the future of oral implantology towards simplification develops, and is also more and more outstanding to stomatologic influence, has broad application prospects.Follow implantation body to drop into the prolongation in clinical practice cycle, simultaneously find that also increasing high risk factor or complication display gradually, handle and several factors such as patient oral cavity underlying diseases all can influence service life of implantation body as implantation body and superstructure design thereof, implant surface, and the bone that the bone regeneration around implant inflammation causes forfeiture is the main cause that implantation body uses failure.Generally acknowledge that now antibacterial is the scorching topmost virulence factor of bone regeneration around implant, the generation of bone regeneration around implant inflammation mainly is because the bone regeneration around implant tissue is subjected to bacterial infection, and then due to wrecking.
Summary of the invention
At above mentioned problem, the micro thread implant that the objective of the invention is can effectively to avoid frontal resorption in order to provide a kind of, suppress the scorching generation of bone regeneration around implant, stability is high, the life-span is long.
To achieve these goals, the technical solution adopted in the present invention is: a kind of micro thread implant, it is characterized in that planting profile and present cylindricality, implantation body adopts thread profile, and described screw thread is symmetrical trapezoidal thread, pitch 0.65 mm, dark 0.4 mm of screw thread, land width 0.1 mm, the implantation body bottom is the arc surface profile, cambered surface radius is 2 mm, implant neck is smooth cervical region, wide is 0.8 mm, and smooth cervical region bottom is cannelure, annular groove width 0.4 mm, groove depth 0.15 mm, implantation body is provided with the self tapping groove, and the self tapping groove has four, and length is 4 mm.
Described implantation body inside is provided with pore structure, and the angle between top vertebral foramen bus and the axis is 45 °, dark 0.75 mm, with taper hole be close to for hexagon ring, the degree of depth 1.5 mm, hexagon ring have the standard thread blind hole, dark 4 mm of blind hole.
Patent of the present invention is owing to adopt above technical scheme, and can obtain following technique effect: 1, implantation body's profile is cylindricality, and cylindricality is dispersive stress most effectively, avoids stress concentration.2, implantation body is provided with helicitic texture, and screw thread can increase the contact area of planting body and osseous tissue effectively, the accelerated bone healing, helicitic texture has auto-lock function simultaneously, increase the stability of implantation body, carry out surperficial coarse language on the helicitic texture, it is long-pending further to increase implant surface.3, cervical region is smooth neck design, and smooth neck is conducive to the cleaning in the operation process, is unfavorable for growing of antibacterial, can prevent the generation of bone regeneration around implant inflammation effectively, increases the life-span of implantation body.4, cervical region has cannelure, and cannelure carries out surface coarsening, increases the contact surface of planting body and osseous tissue, allows smooth neck and screw thread centre that one transition is arranged simultaneously, improves the mechanical property of implantation body.5, bottom arc surface design makes the easier dispersion towards periphery of stress, avoids bottom stress to concentrate.6, implantation body is provided with four spiral self tapping grooves, can realize the self tapping performance of implantation body, reduces operating procedure, and can hold the bits of the bone under the cutting in the self tapping process, is beneficial to bone and integrates, and increases primary stability.7, implantation body and base station coupling part are designed to tapering and add hexagonal, make connection more firm, and can prevent rotation effectively, increase long-time stability, improve implantation body's success rate.
