  • Patent number: 10799369
    Abstract: The strength of bone implant attached to a bone is improved by using hybrid inserts which have stems and wings having bone ingrowth surface features and caps having outer surfaces of cured polymethyl methacrylate (PMMA). The stems and wings of the hybrid inserts are inserted into living bone and the bone implant is attached to the hybrid inserts with PMMA cement. Over time, the bone grows into the bone ingrowth surface features. The bone ingrowth strengthens the bonding of the hybrid inserts and the bone implant with the bone over time. The hybrid inserts increase the shear, tensile and torque strength of the bone implants. Bone inserts that do not have ingrowth surface features loosen over time.

  • Patent number: 10772697
    Abstract: Disclosed is an anatomical drape, such as a dental drape, for covering a treatment area of an anatomical part. The drape includes an elastomeric material capable of conforming to the contours of the anatomical part. The drape preferably includes a curing agent. Activation of the curing agent, for example by a light source, causes selective hardening of the stretched material to at least partially set the drape in a configuration conforming to the anatomical part. The semi-rigid set drape preferably is liquid impermeable but gas permeable. A method of manufacturing the drape is also disclosed.

    Abstract: The bite registration block is used for recording the relation between a patient's maxillary and mandibular arches for proper fabrication of a fixed dental prosthesis, or prostheses, such as fixed crowns or the like. The bite registration block is particularly adapted for use when a patient's prepared teeth are opposed by an edentulous arch (i.e., opposed by an area of missing teeth). The bite registration block is formed from a resilient material, such as a suitable type of plastic or the like, and is formed as a block having opposed upper and lower surfaces, a pair of laterally opposed side surfaces, and a pair of longitudinally opposed side surfaces. The upper surface defines a concave, longitudinally extending recess for positioning about an edentulous region of the patient's jaw.

    Abstract: The invention provides artificial teeth arranged in plates attached in an oral cavity as a dental prosthetic appliance, in which arrangement direction indication parts showing a directivity of arrangement in the plates extending in an apical-cervical direction or in a mesiodistal direction are provided at a vestibular side or an oral side. The arrangement direction indication parts extending in the apical-cervical direction are positioned linearly as seen from the vestibular side in a occluded state of mandibular teeth and maxillary teeth. The arrangement direction indication parts extending in the mesiodistal direction are positioned linearly as seen from the vestibular side in the state arranged in plates. The artificial teeth are arranged at an appropriate position according to an oral environment of each patient, without requiring advanced skills and experiences.

  • Patent number: 7699610
    Abstract: A flexible denture is provided with a denture plate and a false teeth assembly. The denture plate includes a support member and a deformable member. The support member has an approximately U-shaped base, a labial wall and a lingual wall extending from the base, wherein the labial and lingual walls form an approximate U-shaped cross-section along an imaginary vertical plane to form a channel. The deformable member extending across the channel and spaced a distance from the U-shaped base to separate the channel into a gum receiving section and a fitting section, the fitting section including a plurality of ridges extending between the U-shaped base and the deformable member. The deformable member is constructed of soft and pliable material. The false teeth assembly includes a plurality of false teeth secured to the base, the false teeth assembly includes a reinforcing bar embedded within and connecting the plurality of false teeth.

  • Patent number: 7670516
    Abstract: A system of manufacturing a custom set of pre-manufactured upper and lower dentures is provided. In one form, a set of master upper and lower dentures is created. The master upper and lower dentures are used to create reusable upper and lower dental matrices, respectively. These re-usable upper and lower dental matrices are repeatedly used to manufacture upper and lower pre-manufactured or standard sized dentures, respectively. Optionally, a dental patient can have these upper and lower pre-manufactured dentures custom fit or relined to fit the dental patient's mouth to form upper reline and/or lower reline pre-manufactured dentures. The dental patient can have custom fit dentures in two visits with the dentist, even two visits in the same day.

  • Publication number: 20090117518
    Abstract: A denture teeth device having a wire, strand or thread, or a plurality of wires adjustably coupled to a plurality of denture teeth to form a unit. The wire may be adjustably coupled along the lingual-apical portions of the denture teeth. The wire may be flexible to permit development of a dental arch form so that the denture teeth can be readily adapted to individual patient needs. The wire may also serve to improve denture tooth retention in a processed denture base. The wire may be adjustably coupled to the denture teeth so as to not constrain the denture teeth along the length of the wire, allowing for customized arrangement of the denture teeth, including the incorporation of denture tooth overlaps, vertical and horizontal discrepancies, diastemata and facial-lingual and mesial-distal angular variation. The apical and lingual portions of the denture teeth may be contoured to facilitate the creation of anatomically realistic and hygienically favorable papilla forms and occlusion or the patient's bite.

  • Patent number: 7040885
    Abstract: A mold used in duplicating a denture consists of a tissue side mold section and an exterior side mold section. The tissue side mold section is made of a dimensionally stable material, such as dental stone or an addition-cured silicone rubber, so that the tissue side of the denture can be accurately reproduced at a later time. The exterior side mold is made of a resilient material, so that the original denture and its duplicate can be removed from the mold. The mold sections are housed in a two part flask that was initially used to fabricate the mold sections. The mold is fabricated by the steps of forming an impression of the original denture, and of fabricating a replacement denture using this mold.

  • Patent number: 6447294
    Abstract: A locator or signaling device and a detector system for locating lost dentures includes a button or insert that can be mounted on the surface of an existing denture. An insert can also be implanted in a new denture. The internal signaling component is surrounded by a resin layer that can be used to bond the locator button to the existing denture and will also isolate the internal signaling component form the denture wearer's oral cavity. The internal signaling component is responsive to an electromagnetic field and emits a detectable signal when the denture is located with a specified interrogation zone or search area. Signaling components having magnetic characteristics that are altered by an incident variable electromagnetic field can be employed. The preferred location for the locator, locator strip, marker or button is on the interior lingual surface of the flange of a mandibular or lower denture.

  • Patent number: 6139321
    Abstract: A device for dispensing artificial teeth comprises a tooth support ribbon (2) which is made from a flexible material and is shaped to form an arch which substantially corresponds in shape to an upper or lower natural dental arch. A set (10) of artificial teeth (11, 12) is removably mounted on the support ribbon 92) by a slot (13) in each tooth which engages with a key (16) in the ribbon (2). The teeth are arranged on the ribbon (2) in an order which simulates natural dentition. The radius of the arch may be adjusted by an extensible cross-member (3) connected at each end to the ribbon (2) and extending across the arch.
