Abstract

The utility model provides a personalized artificial dental implant which is structurally characterized by comprising an implant and a base, wherein the base is inserted in the implant through a tapered hexagon-octagon to connect; the implant is divided into three parts i.e. a neck, a body and a root tip; two-segment type V-shaped spiral and cylindrical spiral implants are adopted; an expanding and smooth neck is adopted in a non-dive type structure; a short and smooth neck is adopted in a dive type structure; an unobvious neck is adopted in a subperiosteum dive type structure; an inverted trapezoidal spiral is arranged at the upper one third of the body; a rectangular spiral is arranged at the middle one third of the body; a thin rectangular spiral is arranged at the lower one third of the body; three straight anti-rotation grooves are arranged at the root tip; three claws are arranged at the tail end; and the surface of the implant is sintered by using titanium powder to ensure that a micropore is in a micropore and the micropores are communicated. The personalized artificial dental implant provided by the utility model is reasonable in design, innovative in structure, suitable for automatic production, moderate in construction cost to ensure that interns and broad masses can afford and thus easy to popularize.

Description

Personalized manual tooth planting's body

Technical field

This utility model and a kind of dental prosthesis, especially a kind of personalized manual tooth planting's body.

Background technology

Dental Implant is a best restorative procedure behind the absence of tooth of generally acknowledging in the world, promotes through the kind tooth in 20 years in China, launch in a small amount throughout the country, but most what plant is imported product, because of expense is too high, is difficult to popularize.

At present there is triangular thread in implantation body, and cylindrical thread is arranged, and submarine, non-submarine are arranged, and the doctor likes different, Here it is doctor's personalized implantation body.

The utility model content

The purpose of this utility model is to work out a kind of personalized implantation body, can satisfy plantation doctor's individual requirement, and kind is got up more satisfactory, structure innovation, and cost is inexpensive, and broad masses can afford to consume.

The technical scheme that this utility model is taked:

This utility model adopts two-part V-arrangement helical form implantation body, and (1) root tip has three thick anti-rotation grooves; The terminal three-jaw that divides, three-jaw can open a little and expand when the power that is hampered was deepened.(2) body screw thread, last 1/3 for falling trapezoidal thread, the initial stage is difficult for rocking, in 1/3 be rectangular thread, lifting force is bigger, time 1/3 twists into for the thin rectangular shape screw thread easily; (3) cervical region, wearing the gum formula has an expansion and slick cervical region, if hidden a short and smooth neck in the gum, if the subperiosteum submersible does not have smooth cervical region; (4) base station is that lotus lotus shape plug-in type connects, and plug connector is that the taper of 6-8 dihedral patches connection, can increase friction by the enlarged surface area like this; (5) surface treatment is the two micropores of spray titanium valve sintering, and micropore is arranged in the micropore, is communicated with in the hole.Osteocyte can be grown into.

The architectural feature of this utility model:

A kind of personalized manual tooth planting's body comprises implantation body and base station, it is characterized in that adopting two-part helical form V-arrangement implantation body and cylindric spiral-shafted implant:

1. the trapezoidal thread 8 that thickness is 0.4-0.5mm is established on implantation body 6 tops 1/3, and the rectangular thread 9 that thickness is 0.3mm is established at middle part 1/3, and the thin rectangular shape screw thread 10 that thickness is 0.2mm is established in bottom 1/3, and body pitch is 1.25mm, and the thread height is 0.4-0.7mm;

2. implantation body's 6 root tips have three straight anti-spin slots 12, and the wide 0.8-1mm of long 1.5mm, end have three pawls;

3. cervical region 7: wearing gum formula structure has an expansion and the neck of smooth long 2-3mm; The submersible structure has a short and slick neck of 0.8mm in the gum; Subperiosteum submersible cervical region is not obvious;

4. base station 2 has the taper of a 2-8 degree, and the corneous plug connector of 6-8 inserts in the grafting chamber 5 insertion depth 6mm;

5. implantation body 6 surfaces sinter two micropores into the spray titanium valve, and micropore is arranged in the micropore, communicate in the hole.

Personalized manual tooth planting's body of this utility model is reasonable in design, and structure innovation is fit to automated production, and cost is moderate, and intern and broad masses also can be affordable expense, popularize easily.
