Abstract

The invention relates to a crown-connected false tooth structure. The crown-connected false tooth structure is connected with the tooth root of an adjacent tooth implanting structure through a skeleton, and a tooth slit is kept between false teeth; and force applied to the false tooth in a deletion position is conducted to the tooth root of the adjacent tooth implanting structure through the skeleton in the chewing process. The structure can well solve the disadvantages of routine crown connection structures when a crown-connected false tooth structure must be used.

Description

A kind of even hat denture structure and installation method

Technical field

The present invention relates to a kind dental structure and method, particularly connect hat structure.

Background technology

Clinically it can be seen that much connect the baking-ceramic tooth of hat, most commonly seen it be missing from a tooth and do 3 companies and be preced with reparation, also have kind of tooth to carry out what even hat was repaired. It has some shortcomings:

1) uncomfortable, normal natural teeth is all single, and every tooth has normal physiological mobility. It is not motionless on dental bed. Lian Guan is connected to one piece several teeth, is so several tooth stress simultaneously when stress, causes tooth feel abnormal, be somewhat like being worn inhibition, airtight.

2) unsightly, normal labial teeth syntopy is point-like contacts, and the position of each tooth contact point is different. Thus form in picturesque disorder conjunction embrasures and gum nipple profile. And the large area that labial teeth the successive winning of the number on title baking-ceramic tooth adopts connects, heavy damage labial teeth attractive in appearance.

3) being unfavorable for cleaning of teeth, even hat baking-ceramic tooth can not normally use floss neighbour gap. Antibacterial easily grows in adjacent gap, causes periodontitis. Meanwhile, when hat bonding, it is not easy to the binding agent between the adjacent gap of cleaning. Stimulate gingiva so further. This often can see that when the company's of dismounting hat

4) removing difficulty, what baking-ceramic tooth all has the life-span. Need to remove one day. Because the even maintenance strong of hat, it concentrates on one piece the retention of several teeth. Single tooth is all difficult to remove sometimes, and the dismounting misery being even preced with baking-ceramic tooth patient is just well imagined. Certainly, if mastered the technique, some bad hat baking-ceramic tooth done also is relatively good dismounting.

5) being not easy to repair, baking-ceramic tooth certainly has damage in the process used, class such as crackled glaze, tooth recurrent caries, dental nerve infection etc. Single baking-ceramic tooth is very simple, and dismounting is reformed just passable. And being even preced with baking-ceramic tooth is pull one hair and move the whole body, it is likely that need all to remove. The economic loss of such patient is also very big.

6) easy various problem, is even preced with the strength that baking-ceramic tooth is subject to varying in size from all directions in oral cavity. And the cohesive force between each baking-ceramic tooth from abutment is different. Thus easily occur that loosening first occurs in the little baking-ceramic tooth of cohesive force, but owing to being even be preced with baking-ceramic tooth, loosening baking-ceramic tooth will not come off at once. Antibacterial is easily via loosening crevice corrosion abutment. Cause the various symptom such as abnormal flavour, dental pain.

But the use carrying out even being preced with structure of sometimes, but having to, for instance, 3 teeth of consecutive miss, if all carrying out kind of a tooth, it is possible to wound is relatively big, and human body is not easily accepted by, and plants tooth effect also not so good; Also just like intercalary deletion tooth, alveolar bone is not suitable for kind of tooth etc.

Summary of the invention

The technical problem to be solved in the present invention is in that to propose a kind of even hat denture structure and installation method, can overcome the conventional shortcoming being even preced with structure very well when having to the company's of employing hat denture structure.

A kind of company is preced with denture structure, even it is preced with reparation for lacking continuous two teeth, the disappearance place, side of continuous two teeth of described disappearance carries out kind of a tooth, the described opposite side artificial tooth being even preced with denture structure is connected with the root of the tooth planting dental structure of side by skeleton, described opposite side artificial tooth is fixed on skeleton, maintains teeth space between said two artificial tooth; When chewing, the skeleton that is forced through of described opposite side artificial tooth is transmitted on the root of the tooth planting dental structure of described side;

Or be used for lacking continuous three teeth and be even preced with reparation, the intercalary deletion place of continuous three teeth of described disappearance carries out kind of a tooth, the described both sides artificial tooth being even preced with denture structure is connected with the root of the tooth of among dental structure by skeleton, described both sides artificial tooth is fixed on skeleton, maintains teeth space between described both sides artificial tooth and the artificial tooth after among tooth; When chewing, the skeleton that is forced through of described opposite side artificial tooth is transmitted on the root of the tooth of described among dental structure.

Described skeleton is for stretch out from described root of the tooth sidepiece, when being used for lacking continuous two teeth, is used for connecting fixing described opposite side artificial tooth; When being used for lacking continuous three teeth, it is used for connecting fixing described both sides artificial tooth.

The part of described skeleton fixed denture makes the shape similar with the cover screw fixture cover of described kind of dental structure.

Described root of the tooth adopts pure titanium or titanium alloy material, and described skeleton adopts pure titanium or titanium alloy material.

The root of the tooth of described kind of dental structure and skeleton adopt integrated formed structure.

A kind of artificial tooth implanting method, comprises the steps:

(1) the disappearance place, side to the intercalary deletion place/of continuous three teeth of described disappearance or to continuous two teeth of described disappearance carries out the kind of root of the tooth and enters, and is implanted by root of the tooth in alveolar bone, installs simultaneously and fix skeleton;

(2) after alveolar bone heals, appear root of the tooth top, connect cover screw fixture cover;

(3) delivery type in oral cavity, skilled worker room makes Dental implantion both sides artificial tooth, wears tooth; Middle artificial tooth according to modelling is connected with skeleton simultaneously.

Before described root of the tooth kind enters, carry out the force analysis of finite element of skeleton, the occlusion force simulation according to individual, make the skeleton of correspondingly sized section and profile.

The beneficial effects of the present invention is, by adopting skeleton, simulate the situation of single stress of natural teeth as far as possible, improve patient's chewiness and be subject to; In the middle of adopting, the structure that separates with both sides artificial tooth of artificial tooth, has teeth space, reach attractive in appearance, be beneficial to cleaning of teeth and the convenient effect removed and easily repair.
