Description
Technical field
The utility model is related to a kind of tooth implant, more particularly to a kind of personalized tooth implant.
Background technology
With the growth of mankind's average age, the repair of tooth becomes more and more important in medical domain.And dental implant is
The key technology in Dental Erosion field.Be implanted into intraoral tooth implant as outside, it is with alveolar bone bonding strength, itself
Mechanical property and biocompatibility are to influence the principal element of tooth implant using effect.
Some use CT imaging techniques in the prior art, obtain alveolar bone shape, then prepare and alveolar bone shape phase
The tooth implant of matching, the modulus of elasticity (110GPa) of the titanium implant of this compact texture is much larger than the modulus of elasticity (2 of sclerotin
~18GPa), because modulus of elasticity is mismatched, stress concentration and stress-shielding effect are also easy to produce in implant and osseous tissue interface,
Confirmed fatigue destruction occurs for combination interface, and implant gradually produces loosening and causes tooth implant graft failure；
Some use CT imaging techniques in the prior art, alveolar bone modulus of elasticity are obtained, then using sodium chloride occupy-place
Powder co-injection method causes tooth implant to possess certain porosity, prepares the Dental implantion that modulus of elasticity matches with alveolar bone
Body；But this technology prepares tooth implant using mould, shortcoming is that size is single, is needed to realize that perfection is fitted with alveolar bone
Operating shaping is carried out to alveolar bone, complexity is installed and success rate is low.
Base station is separated, pacified first to increase the stability that tooth implant installs initial stage by some prior arts with root of the tooth
Tooth implant is filled, after tooth implant grows and merged completely with alveolar bone, then base station is installed.Tooth implant root of the tooth and base station are two
Individual independent part, using machining standardization generation, root of the tooth needs to be intimately associated with base station, otherwise easily produces seepage etc. no
Good influence, this requirement on machining accuracy to machine is high, high processing costs, follow-up using also inconvenient；And some prior arts are real
Show base station integrated with root of the tooth, but base station volume is excessive so that tooth implant is easily chewed initial stage by base station by upper tooth
Power so that tooth implant is built on the sand；And the too small masticatory force influence for avoiding upper tooth of base station, but the installation of follow-up corona is stranded
Difficulty, it is difficult to which strong bond is on base station.

Technical problem to be solved in the utility model is to provide a kind of personalized tooth implant, the dental implant abutment with
Root of the tooth integration, root shape size matches with original alveolar bone shape size, and root of the tooth modulus of elasticity matches with alveolar bone.
Technical scheme
A kind of personalized tooth implant, includes the root of the tooth and base station of integral type connection, it is characterised in that：Above and below the root of the tooth
It is divided into some sections, if every section is divided into integration connection between inside and outside dried layer, each section of each layer；
Root of the tooth epimere modulus of elasticity is less than root of the tooth hypomere modulus of elasticity, and root of the tooth epimere structural strength is more than segment structure under root of the tooth
Intensity, the outer layer modulus of elasticity of every section of root of the tooth is more than internal layer modulus of elasticity, and the layer structure intensity of every section of root of the tooth is less than internal layer knot
Structure intensity；
The modulus of elasticity and structural strength size of every section every layer of root of the tooth are adjusted by porosity and Numerical Aperture, are realized
Root of the tooth proof resilience modulus after combination matches with alveolar bone modulus of elasticity.
Further, the tooth implant includes root of the tooth epimere and root of the tooth hypomere, and every section is divided into inside and outside two layers, the Dental implantion
The root of the tooth profile of body matches with alveolar bone original shape size, root of the tooth modulus of elasticity and alveolus collagen modulus of elasticity match.
Further, the tooth implant also includes base station, and base station epimere is connected with corona, base station hypomere and root of the tooth one
Formula is connected, and base station hypomere side caves inward so that is formed between base station and gum and wears gum groove, and wearing gum inside grooves is used to fill out
Bonding agent is filled, to improve steadiness of the tooth implant in alveolar bone.
Further, what the base station hypomere side caved inward is shaped as U-shaped, del or I-shaped.
Further, the base station epimere is the round estrade that side has one or more tangent planes, and tangent plane is to increase base station
With the bond area of corona, adhesive strength is improved.
Further, there is groove in the upper surface on the base station, the bonding plane for further increasing base station and corona
Product, improves adhesive strength.
Further, the root surface is provided with one layer of hydroxyapatite overlay film, and the hydroxyapatite thickness is 0.1~
1μm。
Beneficial effect
The root of the tooth of the utility model tooth implant be divided into above and below multistage, if every section is divided into inside and outside dried layer, each section of each layer hole
Rate is different with aperture so that have more combinations, realizes that the root of the tooth proof resilience modulus after combination is more matched with alveolar bone,
Stress shielding effect is avoided, reduces the infringement to alveolar bone, the service life of tooth implant is improved；Root of the tooth size shape and tooth
Groove bone photo is matched, and modification further to alveolar bone shape is avoided in installation process, realizes the painless installation of No operation formula；In addition
The presence of gum groove and bone cement is worn so that tooth implant installs initial stage more consolidates, and base station and the tangent plane of corona connection end
Design causes the two contact surface increase, and with reference to more firmly, the ratio prior art that this allows base station to do is smaller, installs initial stage
Tooth implant more steadiness so that base station and root of the tooth be integrally formed with practicality, it is to avoid in the prior art base station with
Root of the tooth, which is combined, does not cause seepage closely.
