Abstract

The utility model relates to a built-in root canal nail for odontal restoration and repair and belongs to the field of dental restoration. The built-in root canal nail is mainly used for repairing dental deletion of large area and repairing a residual root. The root canal nail comprises three types, i.e. a triangular root canal nail, a P-shaped root canal nail and an L-shaped root canal nail. Each root canal nail consists of a nail core, a nail neck and a nail pile. The triangular root canal nail is commonly used for anterior teeth. The P-shaped root canal nail is commonly used for a large-area carious ring of back teeth. The L-shaped root canal nail is commonly used for repairing the residual root of the back teeth. The built-in root canal nail can not be used for repairing for a case that the bottom of a pulp chamber of the residual root at back teeth is deleted and a case that an abutment tooth is loosened.

Description

Built-in Guan Ding repaired in the reparation of tooth body

Affiliated technical field:

Belong to a kind of new practical apparatus that the direct-type reparation is repaired in the oral cavity in the Oral Repair repairing field

Background technology:

Clinically undesirable root, the labial teeth reparation of wrecking are generally root canal now, row dowel crown reparation or porcelain reparation after placing root Guan Ding after the treatment, the root pipe nail shape of using now is single, usually can only use at labial teeth, reparation requirement that can not each tooth body of to satisfy effectively oral cavity, because present root pipe is followed closely antiacid erosion and anti-oxidant reduction effect is relatively poor, easily the variable color of formation metal surface is reduced and is caused material hardness and Quality Down in the oral cavity, and causes repairing at short notice failure simultaneously.

Summary of the invention:

Because now used root pipe nail poor-performing; for further improving the oral cavity repairing effect; improve the whole service time of dummy; what better the recovery tooth trauma caused is completely cured and the bad tooth body bizet disappearance that causes of large tracts of land dental caries; according to physical friction power principle; simple for requiring with clinical manipulation; improving repairing effect and quality is target; redesign this type of root Guan Ding; according to clinical use and tooth body characteristics, divide three kinds of A with this root pipe nail: triangle root pipe nail B: " P " shape root pipe nail C: " L " shape root Guan Ding.Each root pipe nail is made up of nail nuclear, nail neck, nail stake three parts respectively, nail nuclear is that the outside reveals behind the built-in pipe, the part that merges mutually with repair materials, the nucleopore that comprises nail nucleome and nail nucleome inside, the nail stake is for inserting the part in the root pipe,, stake point prominent by stake, stake face, even surface four parts form, and a nail nuclear part adjacent with the nail stake is for following closely neck.Maximum model triangle root Guan Ding: the nail nuclear shape is trapezoidal, and the top is wide 3 millimeters, and is high 3 millimeters, the built-in triangle nucleopore in center, the nucleopore top is wide 1.5 millimeters, and the nail nucleome is wide 1 millimeter, thick 1 millimeter, the nail neck is four faces, and the length of side of each face is 1.6 millimeters, highly be 1 millimeter, the nail pile length is 10 millimeters, and the sharp stake face triangular in shape that links to each other with the nail neck of stake has high 0.25 millimeter Semicircular pile to dash forward one every 1 millimeter on four faces of nail stake, totally 5, the sharp zone of nearly stake then is even surface.Maximum model " P " shape root pipe ailing nuclear morphology is oval, high 3 millimeters, wide 3 millimeters, built-in and the inconsistent semicircle nucleopore of nail nuclear profile in center, the nucleopore interior diameter is 0.75 millimeter semicircle, the nail nucleome is wide 1.2 millimeters, thick 1 millimeter, the nail neck is four faces, and the length of side of each face is 1.2 millimeters, high 1 millimeter, the nail pile length is 8 millimeters, and the sharp stake face triangular in shape that links to each other with the nail neck of stake has prominent one of high 0.25 millimeter semicircle stake every 1 millimeter on four faces of nail stake, totally 4, the sharp zone of nearly stake then is an even surface.The nail of maximum model " L " shape root Guan Ding is examined L-shaped attitude, the top is wide to be 3 millimeters, high 3 millimeters, following closely nucleome wide is 1 millimeter, thick 1 millimeter, the nail neck is four faces, and nail cervical region and nail nuclear phase connect, and both do not have obvious boundary, the nail nucleome is identical with the numerical value of nail neck, the nail cervical region is four faces, 1 millimeter of each face width, and the nail pile length is 8 millimeters, the sharp stake face triangular in shape that links to each other with the nail neck of stake, one of high 0.25 millimeter half-circle projection is arranged every 1 millimeter on four faces of nail stake, totally 4, the sharp zone of nearly stake then is an even surface.The size variation of root Guan Ding, the radix of nail nuclear, nail neck, nail stake increases on year-on-year basis in its ratio or dwindles.Built-in pipe nail of this kind all is to make with medical stainless steel or medical alloy.

Specific embodiments:

The capable root canal therapy of tooth body of at first individuality being repaired, curative effect reach the requirement of can filling repairing and get final product.Use high speed handpiece or root pipe to enlarge to frustrate etc. canalis radicis dentis is enlarged, length should reach root pipe length overall 2/3 or 3/4 between, remove unnecessary even surface and stake nose part according to measuring length, root canal orifice area after the expansion should account for about 1/3 of the root gross area, after the root pipe sterilized again, transferring a little hydroxy acid zinc cement is placed on rapidly in the root pipe, then root Guan Ding is placed in the root pipe, pressurized filling is sternly cut, the material of making sure to keep in mind filling is parallel with root canal orifice, and pressurization does not make material surpass apical foramen of tooth, and the nail stake should enter the root pipe fully, material should be equal with the nail neck, and nail nuclear then is exposed to fully to be repaired in the district.Can require to select according to individual patients at last the type of reparation.The root Guan Ding different according to the different choice model of root pipe size selects root Guan Ding according to the tooth body different choice of repairing in specie root Guan Ding not.Triangle root Guan Ding is applied in labial teeth more, can do dowel crown, porcelain, replanting property of allogeneic reparation use." P " shape root pipe nail is multiplex to connect repairing in the local large tracts of land disappearance of backteeth." L " shape is used in the core crown or the reparation of replanting property of allogeneic of back residual root of teeth more and uses.It should be noted that the case of Residual posterior root pulp chamber bottom disappearance, the case that abutment is loosening then can not be used the method reparation.
