The invention discloses a method for manufacturing a neutral zone complete denture based on CAD / RP (Computer Aided Design / Rapid Prototyping, computer-aided design and rapid prototyping) technology. The method comprises the following steps: establishing a three-dimensional graphic database of complete dentures and artificial teeth based on parametric positioning; collecting data on the upper and lower edentulous jaws and the jaw embankment in the neutral zone based on the three-dimensional laser scanning technology with spatial position relationships; Based on reverse engineering software, design the complete denture artificial dentition that conforms to the theory of neutral zone and complete denture balanced tooth arrangement; based on reverse engineering software, design the gingiva and base that conform to the theory of neutral zone of complete denture and aesthetic principles; based on CAD / RP technology full denture box design and processing, manual tooth insertion and glue to complete the complete denture restoration. The invention pioneered the idea of ​​"two-step method". The manual teeth arrangement and wax pattern production with the highest technical content and the most complicated operation in traditional production are completed by computer and rapid prototyping technology. The second step of the "step method" can complete the entire production of complete dentures, which greatly simplifies the complicated procedures of traditional handcrafts, improves the efficiency and accuracy of restorations, and realizes the design and production process of complete dentures from manual to manual. Digital transformation.

The invention relates to a buccal multi-bending spring space three-dimensional dynamometer (in figure 2), which is applied to simulating a maxilla, a mandible and a temporom and ibular joint, and predicting the push and pull force values generated on crossover points of the maxilla and the mandible when a correction patient wears multi-bending springs 28I and 28II to perform mouth opening and closing motions. The dynamometer has accurate measurement and can instruct the clinical allopathic wearing according to the following steps: (1) putting two terminal filaments of the 28I and the 28II into a 15I, a 15II and upper jaws 33I and 33II fastening the terminal filaments, and moving a bracket 43 leftwards and rightwards so as to measure the pulling-pressing stress values and the displacements of the 28I and the 28II to a full denture; (2) elongating the 28I and the 28II, fastening the same into holes of the 15I, the 15II, the 33I and the 33II, moving a 32I and a 32II to adjust the stress values to approach to 0, driving a 35, the 32I and the 32II to move rightwards, and measuring the maximum pressing stress value of the full denture of the upper jaw and the lower jaw when the 28I and the 28II are pressed to a mouth-closing state; and (3) measuring the stress values and the displacements of the 28I and the 28II along the scales of 5 degrees, 10 degrees and 15 degrees of a 8I and a 8II by the 15I and the 15II; and if a 21I and a 21II move around a center leftwards and rightwards (the 15I and the 15II are 3 millimeters away from the central displacement), repeating the steps (1) and (2) to measure acting forces and displacement values.

The invention relates to a complete dentition full denture finished product resin tooth, which comprises an upper denture, a lower denture, an upper dentition and a lower dentition, wherein the upper dentition is fixedly connected with the upper denture; the lower dentition is fixedly connected with the lower denture; and the upper dentition and the lower dentition are engaged with each other and are integral dentitions respectively. According to the complete dentition full denture finished product resin tooth, during arrangement of teeth and wearing, the upper dentition and the lower dentition are quickly and centrally engaged, so that the arrangement efficiency of the teeth is increased, the difference in tooth arrangement level of technicians is reduced, and the aims of guaranteeing wide close contact, reducing the clinical occlusal adjustment time and shortening the treatment time of patients are fulfilled. Each tooth is arranged according to an inclination angle in the tooth arrangement standard and positional relation of each dental cusp and an occlusal plane; the upper dentition and the lower dentition are matched teeth and are centrally engaged without error basically; the chair-side occlusal adjustment time of the full denture is reduced; the treatment time is shortened; and the comfort and the satisfaction of patients are improved.

The present invention belongs to the field of medical devices, and in particular relates to a dental complete denture denture care device and its use method, comprising a bottom shell, the lower end of the bottom shell is provided with a water inlet connected to the inside of the bottom shell, the There is a cavity inside the bottom shell, and the center of the bottom of the cavity is provided with a first telescopic shell, and a first telescopic rod is slid inside the first telescopic shell, and the top of the first telescopic rod is detachably connected. There is a top cover, the denture brushing part is provided on the top cover, the denture clamping part is provided at the bottom of the cavity, and pressing parts are arranged symmetrically on both sides of the bottom shell, and the pressing part controls the first A telescopic rod goes up and down, and when the denture clamping part completes the clamping of the dentures, the denture brushing part performs brushing and nursing on the dentures.

The invention provides a semi-finished complete denture based on a prefabricated dentition structure and a rapid production method of the complete denture, aiming at reducing the workload of dentists and technicians and reducing the waiting time of patients under the premise of accurately fitting the patient. The semi-finished complete denture includes a prefabricated temporary base of thermosetting resin material and a prefabricated dentition fixedly combined with it; the prefabricated temporary base is provided with a plurality of strip-shaped holes, and the width of the hole on one side of the polished surface is Slightly larger than the width of the orifice on one side of the tissue surface; the strip-shaped holes in the palatal area of ​​the preformed temporary base of the upper jaw are symmetrically distributed on the left and right, and both ends of the length direction are closed; One end on the top reaches the edge of the preformed temporary base, forming an opening on the edge of the preformed temporary base, and the other end is closed; the distance between the lip-palatal (tongue) and buccal-palatal (tongue) of the preformed temporary base tissue surface is slightly It is greater than the distance between the corresponding parts of the clinical complete denture tissue surface to replace the role of the impression tray and reserve a space for the impression material.

In order to solve the problem of low accuracy and efficiency of the traditional method, the invention provides a method for confirming positions of upper and lower jaws by adopting a 3D printing complete denture individual tray. An upper jaw individual tray (1) which is manufactured in the manner of 3D printing is compounded with a gothic arch tracing plate (2), a lower jaw individual tray (4), a gothic arch guide plate (6), a preformed tracing screw (5) and a preformed fixing ring (7). The individual tray is combined with an intraoral gothic arch and is formed at one time in the manner of 3D printing, so that the manufacturing of the individual tray is more simple, convenient and accurate, the mounting and debugging of the gothic arch are avoided, the clinic operation is greatly simplified and a beginner also can skillfully use the gothic arch for confirming the horizontal jaw position relation. Meanwhile, the manufactured individual tray can be utilized to manufacture the final impression.
