Abstract: front page image
(EN)The present invention provides a dental prosthesis comprising: a pair of retentive grooves for encompassing teeth on both sides of a loss region using an under-cut of a fixture; first and second supports extended to the loss region of one side of the retentive grooves; and an artificial tooth to be coupled to the first and second supports, wherein an inclined plane having a central concave groove is formed downward at an upper portion of the first support, an inclined plane having a locking protrusion corresponding to the concave groove is formed upward at a lower portion of the second support, coupling grooves for coupling the artificial tooth are formed at corners of the first and second supports, respectively, and coupling protrusions corresponding to the coupling grooves are formed inside the artificial tooth. The present invention can firmly and stably couple an artificial tooth without the removal or minimum removal of the fixture by a structure in which an artificial tooth is coupled by the pair of retentive grooves for encompassing teeth using the under-cut of a fixture, and the first and second supports extended to the loss region. In addition, it is possible to enable easy manufacturing and to expect the reduction of manufacturing costs by simplifying the retentive grooves, the first and second supports and the artificial tooth.
(FR)La présente invention concerne une prothèse dentaire comprenant : une paire de rainures de rétention destinées à entourer les dents des deux côtés d'une région de creux en utilisant une contre-dépouille d'un dispositif de fixation; un premier et un second support s'étendant sur la région de creux d'un côté des rainures de rétention; et une dent artificielle à coupler au premier et au second support, un plan incliné comprenant une rainure concave centrale se formant vers le bas au niveau d'une partie supérieure du premier support, un plan incliné comprenant une protubérance de verrouillage correspondant à la rainure concave se formant vers le haut au niveau d'une partie inférieure du second support, des rainures d'accrochage destinées à accrocher la dent artificielle se formant aux coins du premier et du second support, respectivement, et des protubérances d'accrochage correspondant aux rainures d'accrochage se formant à l'intérieur de la dent artificielle. La présente invention peut permettre de fixer de manière ferme et stable une dent artificielle sans extraction du dispositif de fixation ou une extraction minime de celui-ci par le biais d'une structure dans laquelle une dent artificielle est accrochée grâce à la paire de rainures de rétention destinées à entourer les dents en utilisant la contre-dépouille d'un dispositif de fixation, et le premier et le second support s'étendant sur la région de creux. De plus, il est possible de mettre en œuvre un procédé de fabrication simple et de s'attendre à des coûts de fabrication plus faibles grâce à la simplification des rainures de rétention, du premier et du second support et de la dent artificielle.
(KO)본 발명은 지대치의 언더컷을 이용하여 상실부위의 양쪽 치아를 감싸도록 형성된 한 쌍의 유지구와, 상기 유지구의 일측에 상실부위로 연장형성된 제1,2 지지구와, 상기 제1,2 지지구에 결합되는 인공치로 구성되어지되, 상기 제1 지지구의 상부에는 중심에 오목홈이 구비된 경사면이 하방향으로 형성되고, 상기 제2 지지구의 하부에는 상기 오목홈에 대응하도록 잠금돌기가 구비된 경사면이 상방향으로 형성되며, 상기 제1,2 지지구의 모서리부에는 인공치를 결합하기 위한 결합홈이 각각 형성되고, 상기 결합홈에 대응하도록 상기 인공치의 내측에는 결합돌기가 형성되도록 구성되는 치과용 보철물을 제공하기 위한 것으로, 본 발명은 지대치의 언더컷을 이용하여 치아를 감싸도록 형성된 한 쌍의 유지구와 상기 유지구의 일측에 상실부위로 연장형성된 제1,2 지지구에 의해 인공치가 결합되는 구조로 인해 상기 지대치를 무삭제 또는 최소 삭제하여 인공치의 견고하고 안정적인 결합이 가능할 뿐더러 상기 유지구 및 제1,2 지지구, 인공치의 단순화로 인해 제작이 쉽고 생산단가의 비용절감을 기대할 수 있도록 하는 매우 유용한 발명인 것이다.
