Definitions
- the present invention relates to an impression tray that includes an upper jaw impression tray and a lower jaw impression tray, which are used when taking an impression in the production of a denture base.
- impression materials such as silicone impression materials and alginate impression materials are used to obtain an intraoral impression when preparing a prosthesis in dental treatment.
- an impression tray is used to insert and hold the impression material in the oral cavity. That is, the impression material is placed on the impression tray and inserted into the patient's mouth, and the impression material is pressed into the patient's mouth to transfer the shape of the mouth to the impression material. Then, after the impression material is cured, the impression tray is taken out from the oral cavity as a single body while the impression material to which the shape in the oral cavity is transferred is held.
- a first impression of the alveolar ridge is first taken with a general impression tray, and then an edentulous jaw model is produced from the cured impression. From this edentulous jaw model, an “individual tray” that is an impression tray dedicated to the edentulous person is produced. Next, a thin impression material is placed on the personal tray, and the second impression of the alveolar ridge is obtained, and an accurate edentulous jaw model is produced from the impression.
- plaster models were obtained by pouring plaster into this personal tray, but recently, with the development of digitization technology and CAD technology, for example, as described in Patent Document 1, the acquired impression is used as three-dimensional shape data.
- the dental prosthesis can be adjusted to the final shape on the computer, and the final product can be directly produced by transmitting the data of the final shape to the NC machine tool.
- the impression tray extends so as to protrude from the oral cavity to a portion on the lip side in order to appropriately dispose the main body of the impression tray in the oral cavity of the patient.
- a handle is provided.
- Patent Document 1 there is no description on how to obtain the data by specifically rotating the impression tray when three-dimensionally measuring the obtained impression. Three-dimensional measurement needs to be performed on both the upper and lower jaw impressions, which is troublesome because of the relationship between the front and back.
- the impression formed on the upper jaw side and the lower jaw side can be measured by fixing the handle to the holding device by holding the handle and holding the impression upright.
- the lip side impression data may not be acquired by the handle.
- an object of the present invention is to provide an impression tray that facilitates acquisition of three-dimensional data.
- the present invention provides an impression tray (1) for holding an impression material that is inserted into the oral cavity and obtains an impression, and an upper jaw impression tray (10) that deposits an impression material for obtaining an impression on the upper jaw side, and a lower jaw side
- the upper jaw impression tray has an upper jaw impression tray body (11) having a surface (12a) on which the impression material is to be placed, and has a lower jaw impression
- the tray has a lower jaw impression tray body (21) having a surface (22a) on which impression material is to be stacked, and a handle (17) is detachably provided on at least one of the upper jaw impression tray body and the lower jaw impression tray body.
- the handle is an impression tray that protrudes from the lip side, the surface on which the impression material of the upper jaw impression tray is to be placed, and the surface on which the impression material of the lower jaw impression tray is to be placed in the mounting posture.
- the upper jaw impression tray main body (11) and the lower jaw impression tray main body (21) have surfaces (12a, 22a) on which impression material is to be placed and opposite side surfaces (12b, 22b). ) Through holes (12c, 22c) may be provided.
- the handle when an impression is taken, the handle is detached and does not hinder the taking of the impression.
- a handle extending from other than the part to be measured is attached. Since the tray can be held in the space, the required impression can be measured easily and accurately

Abstract
Description
次にこの個人トレーに印象材を薄く盛り、歯槽堤の2回目の印象を採得し、その印象から正確な無歯顎模型を作製する。
上顎印象トレー本体11は、上顎における口腔内の概ねの形状を模した外周形状及び凹凸を有して形成された板状の印象材受け板12を有しており、一方の板面が印象材が配置される印象材配置面12a、他方の板面が下顎印象トレー20に対向する下顎印象トレー対向面12bである。そして、印象材受け板12には、印象材が押圧されて変形したときに印象材を逃がすために板厚方向に貫通する複数の穴12cが設けられている。また、この穴12cから押し出された印象材により上顎印象トレー10が下顎印象トレー20とくっつき、両者を一体にすることができる。
本形態では、使われる印象材の量を減らすことができる観点から、印象材受け板12の形態を上顎における口腔内の概ねの形状を模した外周形状及び凹凸を有する形態とした。すなわち、その外周形状は歯列弓形状を模した湾曲をした形状とされており、口唇側に凸となるように形成されている。そしてその板面は顎堤部に対応する部位が弓状に下顎印象トレー対向面12b側に凸、印象材配置面12a側に凹となり、この弓状に囲まれる硬口蓋部に対応する部位が印象材配置面12a側に凸となるように凹凸を有している。ただし、必ずしも印象材受け板はこの形状に限定されることなく、公知の上顎印象トレーに採用されている形状を適用することもできる。
本形態で突起13は、印象材受け板12の下顎印象トレー対向面12bのうち、下顎印象トレー対向面12b側に凸となった弓状の部位の稜線(凸の頂部を結ぶ線)上の2か所に配置されている。突起の形状は特に限定されることはないが、稜線に沿った方向の長さ(図2にAで示した長さ)が5mm以上20mm以下、該方向に直交する幅方向の大きさ(図2にBで示した大きさ)が3mm以上10mm以下であることが好ましい。この長さが5mm未満では短すぎて咬合位置及び高さを決める際に突起13と、後述する下顎印象トレー20の突起23(図1参照)との互いの頂面13a、23aの少なくとも一部同士を接触させることができない可能性が高まる。一方で長さが20mmを超えると、頂面13a、23aを傾けたり、その位置を保つことが困難となる。幅方向の大きさについては、3mm未満では狭すぎて咬合位置及び高さを決める際に突起13と、後述する下顎印象トレー20の突起23との互いの頂面13a、23aの少なくとも一部同士を接触させることができない可能性が高まる。一方、幅が10mmを超えると突起13、23が頬に当たる虞がある。
摘み部18は一方に長く延びる板状の部材である。連結部19は摘み部18の一方の面のうち、摘み部18の長手方向一方側に寄せられて配置された2つの突起である。連結部19は上記したように、口唇側連結部14、喉側連結部15に装着及び離脱する形状とされている。
図4(a)は、上顎印象トレー本体11からハンドル17が離脱され、上顎印象トレー本体11のみの形態である。
図4(b)は、上顎印象トレー本体11の喉側連結部15にハンドル17が装着された形態である。これは上顎印象トレー本体11の喉側連結部15にハンドル17の連結部19が装着されることにより行われる。この形態とされることにより、ハンドル17の摘み部18が印象材受け板12から喉側(すなわち、口唇側とは反対側)に突出する。
図4(c)は、上顎印象トレー本体11の口唇側連結部14にハンドル17が装着された形態である。これは上顎印象トレー本体11の口唇側連結部14にハンドル17の連結部19が装着されることにより行われる。この形態とされることにより、ハンドル17の摘み部18が印象材受け板12から口唇側に突出する。
下顎印象トレー本体21は、下顎における口腔内の概ねの形状を模した外周形状及び凹凸を有して形成された板状の印象材受け板22を有しており、一方の板面が印象材が盛られる印象材配置面22a、他方の板面が上顎印象トレー10に対向する上顎印象トレー対向面22bである。そして、印象材受け板22には、印象材が押圧されて変形したときに印象材を逃がすために板厚方向に貫通する複数の穴22cが設けられている。また、この穴22cから押し出された印象材により下顎印象トレー20が上顎印象トレー10とくっつき、両者を一体にすることができる。
本形態では、使われる印象材の量を減らすことができる観点から、印象材受け板22の形態を下顎における舌部を除く口腔内の概ねの形状を模した外周形状及び凹凸を有する形態とした。すなわち、その外周形状は歯列弓形状を模した湾曲をした形状とされており、口唇側に凸となるように形成されている。そしてその板面は顎堤部に相当する部位が弓状に上顎印象トレー対向面22b側に凸、印象材配置面22a側が凹となり、この弓状に囲まれる中央部は舌部となるので空隙とされている。ただし、必ずしも印象材受け板はこの形状に限定されることなく、公知の下顎印象トレーに採用されている形状を適用することもできる。
本形態で突起23は、印象材受け板22の上顎印象トレー対向面22bのうち、上顎印象トレー対向面22b側に凸となった稜線(凸の頂部を結ぶ線)上の2か所に配置されている。突起の形状は特に限定されることはないが、稜線に沿った方向の長さ(図5(a)にCで示した長さ)が5mm以上20mm以下、該方向に直交する幅方向の大きさ(図5(a)にDで示した大きさ)が3mm以上10mm以下であることが好ましい。この長さが5mm未満では短すぎて咬合位置及び高さを決める際に突起23と、上記した上顎印象トレー10の突起13との互いの頂面13a、23aの少なくとも一部同士を接触させることができない可能性が高まる。一方で長さが20mmを超えると、頂面13a、23aを傾けたり、その位置を保つことが困難となる。幅方向の大きさについては、3mm未満では狭すぎて咬合位置及び高さを決める際に突起23と、上記した上顎印象トレー10の突起13との互いの頂面13a、23aの少なくとも一部同士を接触させることができない可能性が高まる。一方で幅が10mmを超えると突起13、23が頬に当たる等の虞がある。
次に印象材受け板12、22の印象材配置面12a、22aにそれぞれ印象材を盛り、ハンドル17を掴んで上顎印象トレー10を上顎側、下顎印象トレー20を下顎側の口腔内に配置する。このとき、上顎印象トレー10に配置された印象材が口腔内の上顎のうち硬口蓋及び歯槽堤に接触するように、及び下顎印象トレー20に配置された印象材が口腔内の下顎のうち歯槽堤に接触するように配置される。従って、口腔内で上顎印象トレー10の下顎印象トレー対向面12bと、下顎印象トレー20の上顎印象トレー対向面22bとが対向している。その後、上顎印象トレー10のハンドル17及び下顎印象トレー20のハンドル17が離脱される。
これにより上顎の硬口蓋、歯槽堤の印象、下顎の歯槽堤の印象、及び穴12c、22cから押し出された印象材が口唇部の口腔内側に充填されてこの部位における印象がそれぞれ採得できる。
このとき、ハンドル17が取り外されているので、ハンドル17が口唇に当たることによる不正確な印象形成が防止される。またハンドル17が喉側連結部15に装着されていないので、口腔内への配置をハンドル17が阻害することはない。
また、この印象材(E)により上顎印象トレー10と下顎印象トレー20との位置が固定されて両者が一体化する。
3次元データを取得するための計測装置は公知のものを用いることができる。例えば、レーザによる方法や、撮影した写真を合成する方法等を挙げることができる。
