Abstract
A firm artificial tooth has a fixing unit and a tooth base, and features that an isolated tooth corona has an inner hole and its tooth neck has a fastening hole for tighly fixing the artificial tooth to the abutment tooth. Its advantages are simple and feasible method, high strength and not colouring easily.
Description
The present invention relates to the technology of having a denture made, specifically artificial tooth of edge system and preparation method thereof.
Tooth is the important component part of organ of mastication.Incisor, lateral incisor, canine tooth, bicuspid and grind one's teeth in sleep and share out the work and help one another are finished the task of chewing jointly.Simultaneously, tooth to the variation of periodontal tissue, develop and keep facial appearance and attractive in appearance important effect arranged all.Just because of this, behind tooth defect, its reparation is very important.Present modal restorative procedure is an edge system removable denture.Removable denture is made up of artificial tooth, substrate, retainer, dens supporter etc.The characteristics of this method are easy to make, and can take off cleaning, but its weak point is that existing artificial tooth still has many imperfect parts.For example, though porcelain tooth matter is hard, anti-crushing power is strong, and is not easy to wear, chews the ability height, and glossiness is good, and the likeness in form dermal tooth is difficult for polluting variable color, and fragility is big, and jackknifing easily is difficult for mill and changes when row's tooth, can not recover former glossy behind the surface abrasion.Plastic cement tooth toughness is big, is difficult for jackknifing, grind conveniently, and mill is easy to polishing after changing, but its hardness is low, and wearing and tearing easily, masticatory efficiency is poor, and the polishing degree is not high, pollutes variable color easily; The metal facing tooth so hardness is big, can bear big pressure because of metal is arranged, and is difficult for breaking, and changes and not attractive in appearance, nature but be difficult to grind.For fear of many weak points of artificial tooth, medical circle is always at the research and utilization ex vivo tooth, as tooth replantation, be exactly the tooth that will exsomatize after treatment, be implanted to again in the poor nest of original tooth, make tooth firm, recover masticatory function.This method keeps the distinctive performance of the natural tooth of people, but the technical operation of this method is strict, and it is generally acknowledged tooth exsomatize be implanted as in 30 minutes suitable, otherwise periodontal membrane edema, degeneration, the growth that is unfavorable for implanting tooth.This has just limited its extensive use.In addition, replantation tooth also has bigger restriction to patient age, generally along with the increase at age, replants success rate and also decreases.
Purpose of the present invention just provides a kind of well behaved artificial tooth that makes full use of ex vivo tooth, and another object of the present invention just provides a kind of method of simple, convenient, practical this artificial tooth of preparation.
The present invention seeks to realize like this, select for use ex vivo tooth to substitute the artificial tooth and prepare artificial tooth, the same with common artificial tooth, also include retainer, dens supporter, the key of design is in the inside of corona one cavity to be set, be provided with fastener hole on tooth neck position, retainer fixes by the fastener hole on the neck and dens supporter, abutment.
Second purpose of the present invention is achieved in that by following method and prepares artificial tooth:
A, the intact ex vivo tooth of selection corona;
B, carry out ex vivo tooth and handle, promptly remove dental pulp in the ex vivo tooth, soaked 20-30 minute with antiseptic solution.Disinfectant solution can be selected disinfectant solution medically commonly used for use, as saline antibiotic solution, bromo geramine, formalin solution or the like.Be as the criterion with the purpose of Danone to sterilization.Mainly be to prevent bacterial reproduction in the ex vivo tooth, to influence the utilization again of ex vivo tooth.
C, upwards in corona, dig a cavity from corona bottom.
D, pass dentin at tooth neck position and prepare fastener hole;
E, according to die, remove the root of the tooth of redundance, to be suitable for the concrete condition of patient's dental bed.
F, retainer are connected and fixed by the fastener hole of corona, prepare dens supporter more according to a conventional method, just are prepared into firm, durable artificial tooth.
Innovation part of the present invention is, has effectively utilized the tooth that human body comes off.Because intensity, toughness, the light of natural teeth are spent clearly, aesthetics is present any artificial tooth can not compare, this artificial tooth with the ex vivo tooth preparation, restrained that existing artificial tooth's fragility is big, easily jackknifing, many weak points such as easy to wear, easy to change, not attractive in appearance, its method is simple again.This in addition method can not be subjected to the restriction of tooth isolated time to the utilization again of ex vivo tooth, and the patient needn't consider that also whether suitable self or the like at age, thereby has significantly reduced the limitation that original ex vivo tooth utilizes.
Below in conjunction with drawings and Examples, be described in further detail artificial tooth of the present invention and preparation method thereof.
Embodiment
The present invention has solid position, dens supporter, and in preparation during artificial tooth, retainer can be with the stainless steel silk formed retainer of 0.7mm or 0.8mm, and the corona form of artificial tooth is partly selected the intact ex vivo tooth of corona for use, to keep the artificial tooth excellent function.After tooth breaks away from human body, should carry out the processing of ex vivo tooth earlier, be about to the dental pulp Ex-all of ex vivo tooth, soaked 30 minutes with bromo geramine, with the antibacterial in the thorough elimination tooth, virus.The ex vivo tooth of disinfecting can be positioned in the sterilization container standby.When preparing artificial tooth of the present invention, the ex vivo tooth that will disinfect upwards digs hole 3 in bottom corona (1) as shown in Figure 1, and big following little form above preferably make interior hole (3) is so that the artificial tooth installation is more firm.Both sides at neck 5, pass dentin 4 and make a call to a fastener hole 6 respectively, retainer can tighten together artificial tooth and dens supporter, abutment by this hole, and with fixing, support and stable artificial tooth, two outsides of corona 1 are used for dental drill most, and each makes a call to the pothole 2 of a grain of rice size, to be used for when preparing dens supporter, dental base acrylic resin powder is together poured into, make the tooth body more firm, pothole 2 is young greatly in preferably, when being used to prepare dens supporter, can make itself and dens supporter pour into more firmly.
When the preparation artificial tooth, select the length of root of the tooth according to the die of manufacturing, the root of the tooth of redundance is removed, the corona part is complementary with other tooth.Retainer is connected and fixed with corona, dens supporter by the fastener hole 6 of corona, the method for preparing dens supporter is a conventional method, promptly to abutment prepare, impression taking, duplicate cast, bending clasp, row's tooth, wax system base, dress box etc., make artificial tooth integral body, with the adaptation that matches of the corresponding position at the former agomphosis of patient position.
Claims (5)
