    • PROBLEM TO BE SOLVED: To simply and quickly determine a grinding portion of a denture and to easily perform grinding.SOLUTION: A jaw-relation reproduction condition is determined by measuring a jaw movement of a patient and a jaw state of the patient on an occlusion-state reproducing apparatus is reproduced in accordance with the jaw-relation reproduction condition. Dentures are arranged on the apparatus in accordance with the jaw-relation reproduction condition to prepare pre-grinding dentures. Denture data with reference points which are three-dimensional image data containing reference points that represents a positional relationship between the jaw-relation reproduction condition and the dentures and an occlusal surface of the dentures. An occlusion state of the denture data with the reference points is reproduced on a three-dimensional image by using the jaw-relation reproduction condition. Grinding data of a grinding portion are determined under a dynamic condition or set condition from a portion surrounded by an image of upper and lower jaws on the three dimensional image in a reproduced occlusal state. Denture data with reference points with grinding data in which grinding data are added to the denture data with reference points are prepared. Pre-grinding dentures are ground on the basis of the denture data with reference points with grinding data.
    • 要解决的问题:简单快速地确定义齿的磨削部分并且容易地进行研磨。 解决方案:通过测量患者的颌运动来确定颌关系再现条件,并且根据颚关系再现条件再现闭塞状态再现装置上的患者的颌状态。 根据颚关系再现条件将假牙布置在装置上以制备预研磨假牙。 具有参考点的假牙数据是三维图像数据,其包含表示颌关系再现条件与义齿之间的位置关系的参考点和假牙的咬合面。 通过使用颚关系再现条件,在三维图像上再现具有参考点的义齿数据的遮挡状态。 磨削部分的磨削数据在动态条件或设定条件下由在再生咬合状态下的三维图像上的上下钳口的图像围绕的部分确定。 准备具有参考点的假牙数据,其中将研磨数据用参考点添加到义齿数据中。 基于具有研磨数据的参考点的假牙数据研磨预磨假牙。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To easily and rapidly determine an occlusal adjustment portion of a denture and easily grind it.SOLUTION: The method for determining an occlusal adjustment part includes the steps of: (A) an identification step for rubbing natural teeth data portion in upper and lower jaws for identifying a rubbing natural teeth data portion in the upper and lower jaws in maxillomandibular 3D-data; (B) an identification step for smooth sliding of natural teeth portion face data for identifying so that the rubbing natural teeth data portion in the upper and raw jaws and the prosthesis data are laid on each other and the prosthesis data is smoothly slid on the rubbing natural teeth data portion in the upper and raw jaws; and (C) a determination step for an occlusal adjustment portion of determining an occlusal adjustment portion by moving maxillomandibular 3D-data along with at least one face data of rubbing natural teeth portion and remaining a trace of a region surrounded by 3D-data on the side of prosthesis data to determine a region surrounded by the 3D-data as an occlusal adjustment portion.
    • 要解决的问题:容易且快速地确定义齿的咬合调节部分并且容易地研磨。 解决方案:用于确定咬合调整部件的方法包括以下步骤:(A)用于摩擦上下钳口中的自然齿数据部分的识别步骤,用于识别上下钳口中的摩擦天然齿数据部分 上颌下3D数据; (B)用于使天然牙齿部分面部数据平滑滑动的识别步骤,用于识别,使得上部和下部颌部中的摩擦天然牙齿数据部分和假体数据彼此铺设,并且假体数据在摩擦上平滑滑动 天然牙齿数据部分在上,下爪中; 和(C)用于通过移动上颌下颌3D数据以及摩擦天然牙齿部分的至少一个脸部数据来确定咬合调节部分的咬合调整部分的确定步骤,并且在3D模型上保留由3D数据包围的区域的痕迹 以确定由3D数据包围的区域作为咬合调整部分。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To reduce work of occlusal adjustment and to acquire accurate occlusion by a dentist or a dental technician creating dentures themselves and a special trader carrying out occlusal adjustment.SOLUTION: Occlusal-surface shape data and occlusal-surface position data of dentures are acquired on a dentist side, and the data are then transmitted to a grinding data provider side. A maxillomandibular occlusal state is reproduced on the grinding data provide side from the occlusal-surface shape data and occlusal-surface position received from the dentist side and a maxillomandibular occlusal adjustment portion is determined by changing a maxillomandibular occlusal vertical dimension. Cutting data comprising the occlusal adjustment portion data and the occlusal-surface position data are prepared on the grinding data provider side and the cutting data are transmitted to the dentist side. Occlusal adjustment is carried out by cutting the dentures by a grinding machine on the basis of the cutting data on the dentist side.
    • 要解决的问题:减少咬合调整的工作并获得由牙科医生或牙科技师进行准确闭塞,从而产生假牙本身和进行咬合调整的特殊贸易商。 解决方案:在牙医方面获取假牙的咬合面形状数据和咬合面位置数据,然后将数据传输到研磨数据提供方。 通过改变上颌颌骨咬合垂直尺寸来确定从咬合面形状数据和从牙医一侧接收的咬合面位置的研磨数据提供侧的上颌颌骨咬合状态,并且确定上颌下颌咬合调整部。 在磨削数据提供者侧准备包括咬合调整部分数据和咬合面位置数据的切削数据,并将切割数据传送到牙医一侧。 基于牙医一侧的切割数据,通过研磨机切割假牙进行咬合调整。 版权所有(C)2012,JPO&INPIT
