34 results about "Dentures" patented technology

Dentures (also known as false teeth) are prosthetic devices constructed to replace missing teeth, and are supported by the surrounding soft and hard tissues of the oral cavity. Conventional dentures are removable (removable partial denture or complete denture). However, there are many denture designs, some which rely on bonding or clasping onto teeth or dental implants (fixed prosthodontics). There are two main categories of dentures, the distinction being whether they are used to replace missing teeth on the mandibular arch or on the maxillary arch.

A modular denture with adjustable mounting height

PendingCN122297150ANatural toothDentures
This invention discloses a modular denture with adjustable installation height, comprising an installation base with multiple installation cavities at the top and multiple positioning slots at the bottom; multiple dentures are movably fitted into their respective installation cavities, with their roots movable vertically within the cavities; and a lifting drive mechanism, embedded in each installation cavity, for independently driving the corresponding denture for height adjustment; the lifting drive mechanism includes: an adjusting shaft horizontally rotatable inside the installation base, one end of which extends out of the side wall of the installation base to form an operating end; and a driven shaft vertically rotatable within the installation cavity; when the adjusting shaft rotates, it drives the driven shaft and lead screw to rotate via a bevel gear transmission mechanism, causing the threaded slider and dentures to rise and fall vertically, thereby achieving denture height adjustment. This invention solves the problem that most existing dentures use a fixed connection with the base, making it difficult to adjust the height after installation and to personalize the adjustment according to the actual height of the patient's natural teeth.

Apparatus and method for manufacturing a bioabsorbable denture

This invention relates to the field of denture printing equipment, specifically to a manufacturing device and method for bioadhesive dentures. The device includes a printer housing, a worktable located in the center of the housing, a scraper sleeve slidably mounted on the worktable surface, and two scrapers offset at the lower part of the scraper sleeve. It also includes a switching mechanism movably mounted on both sides of the scraper sleeve for driving the two scrapers to switch positions, and an anti-adhesion mechanism movably mounted between the inner wall of the scraper sleeve and the scrapers to prevent foam from adhering to the surface of the scrapers after switching. In this bioadhesive denture manufacturing device, the anti-adhesion mechanism compresses a corresponding airbag at its top when the scraper rises to the switching position. The compressed airbag continuously sprays a directional airflow through an exhaust pipe and nozzle to the scraper area of ​​the next position. This airflow forms an air curtain barrier before the scraper enters the printing area, blowing away scum and residual foam from the collection area during the self-cleaning process from the scraper surface, preventing them from being carried back to the resin surface when the scraper resets.

A method for personalized occlusal surface design of fully anatomical dentures

PendingCN122310873AComputer Aided DesignOral tissue
This invention discloses a personalized occlusal surface design method for fully anatomical dentures, belonging to the field of computer-aided design technology. The method first obtains the instantaneous rotation center change rate sequence of the condyle after joint damping correction, the contact points on the guide ramp of the designed tooth, and the corresponding contact points on the functional ramp of the opposing tooth. Then, it obtains the normal curvature and the difference in normal curvature along the relative motion direction at the contact points and their corresponding points. Combining the instantaneous rotation center change rate after joint damping correction, the difference in normal curvature, and oral tissue material parameters, a multi-objective comprehensive evaluation coefficient is constructed. Finally, with the goal of minimizing this coefficient, the occlusal surface morphology of the designed tooth is iteratively optimized until the evaluation coefficients of all contact points meet a preset threshold. This invention, by introducing joint damping correction and a multi-objective optimization strategy, achieves personalized design of the denture occlusal surface, effectively improving the biomechanical adaptability, chewing efficiency, and long-term stability of the denture.
