Fixed space regainer
The fixed space regainer is a resin band designed to regain space in the gap between the remaining teeth when a tooth is lost. The band has opposing concave ends that provide bonding surfaces or anchors that attach to the remaining teeth on opposite sides proximal to the gap and an elongate connecting band between the bonding surfaces. The regainer is made from a biocompatible elastic material so that the connecting band will arch when installed across the gap and exert resilient pressure against the remaining teeth proximal to the gap to regain the space lost by narrowing that occurs by loss of the tooth, thereby providing proper spacing for growth of a permanent tooth or installation of a cosmetic replacement. The regainer may be designed by the dentist in software from a digital impression and made by 3D printing or additive manufacturing.
IMPLANT PELLETS AND METHODS FOR PERFORMING BONE AUGMENTATION AND PRESERVATION
Embodiments described herein are related to pellets that are placed within an extraction site that is in need of bone augmentation and preservation. The pellets are typically cylindrical in shape and comprise a material and a polymer coating. The pellets may advantageously facilitate sufficient new bone growth that jaw bone deterioration is prevented. The pellets create, arrange, and assemble an ideal growth environment for new bone growth to rapidly grow and preserve the original contours of an individual's jaw bone.
Osseointegrative surgical implant
Embodiments of the present invention provide an osseointegrative implant and related tools, components and fabrication techniques for surgical bone fixation and dental restoration purposes. In one embodiment an all-ceramic single-stage threaded or press-fit implant is provided having finely detailed surface features formed by ceramic injection molding and/or spark plasma sintering of a powder compact or green body comprising finely powdered zirconia. In another embodiment a two-stage threaded implant is provided having an exterior shell or body formed substantially entirely of ceramic and/or CNT-reinforced ceramic composite material. The implant may include one or more frictionally anisotropic bone-engaging surfaces. In another embodiment a densely sintered ceramic implant is provided wherein, prior to sintering, the porous debound green body is exposed to ions and/or particles of silver, gold, titanium, zirconia, YSZ, α-tricalcium phosphate, hydroxyapatite, carbon, carbon nanotubes, and/or other particles which remain lodged in the implant surface after sintering. Optionally, at least the supragingival portions of an all-ceramic implant are configured to have high translucence in the visible light range. Optionally, at least the bone-engaging portions of an all-ceramic implant are coated with a fused layer of titanium oxide.
DENTAL DUAL-STRUCTURED MEMBRANE AND METHOD FOR MANUFACTURING DENTAL DUAL-STRUCTURED MEMBRANE
Provided is a dental dual-structured membrane. The dental dual-structured membrane according to an embodiment of the present inventive concept includes a shielding portion for shielding a bone grafting material and an alveolar bone from the outside to prevent infiltration of other tissue cells, and an insertion and fixing portion connected to the shielding portion and inserted between a gum and the alveolar bone to fix the shielding portion, in which the insertion and fixing portion has a higher tensile strength than the shielding portion.
Method of producing bioabsorbable membrane
A method of producing a bioabsorbable membrane includes: forming a liquid membrane by spin-coating a coating liquid containing a first bioabsorbable polymer and a solvent; and forming a dense layer by causing a porous membrane containing a second bioabsorbable polymer to contact the liquid membrane.
Dental implant
Dental implant embodiments comprising one or more non-annular cutaways from a portion of the crown are described. In some embodiments, cutaways, which are implantable beneath the bone line, are orientable during implantation by reference to a dental implant positioning tool to which the dental implant is mated in a known orientation. Mating, in some embodiments, is secured by a detent system which reversibly interlocks the positioning tool and the implant. In some embodiments, a surface of a cutaway is provided with protrusions which stimulate bone regrowth into the volume which the remainder of the cutaway provides.
DEVICE AND METHOD FOR TREATMENT OF AN ARTIFICIAL BONE IMPLANT WITH BLOOD
A device for treating an artificial bone implant with blood, the device comprising: a container configured to accommodate an artificial bone implant and be filled with blood, wherein the container comprises an opening and a cover configured to cover the opening of the container. Additional embodiments of the device and methods for using the same are disclosed herein.
Bone foundation guide system and method
A bone foundation guide system and method, the system could includes a bone foundation guide including a body forming an open surgical space, the body further having a bottom contoured to reversibly affix to exposed bone of a dental surgical site and a top contoured to match a bottom side of a dental implant surgical guide; at least one anchoring strut that removably attaches to the body with an apex of the anchoring strut further denoting one or more indentations for matching up with and receiving one or more portions of one alveolar ridge that opposes another alveolar ridge supporting the dental surgical site; alternatively to the anchoring struts and a tissue spacing gasket, the dental implant surgical guide that removably connects to the body; and alternatively to the anchoring struts or the dental implant surgical guide, the tissue spacing gasket that removably connects to the body.
MEDICAL IMPLANT WITH DISCONTINUOUS OSSEOINTIGRATIVE SURFACE
A medical implant includes a base portion configured for implantation into a bone of a patient. The base portion is formed from an electrically insulating and biocompatible base material with retaining features on an outer surface of the base portion for gripping the bone in the patient. A plurality of titanium bands is positioned along the outer surface of the base portion.
ABUTMENT AND HEALING CUFF DEVICE FOR DENTAL IMPLANT
The invention relates to an intermediate dental abutment (2), intended to be inserted into a dental implant (1), the intermediate abutment (2) comprising: a lower part (20), intended to be inserted into an implant (1); an intermediate part (28), comprising an external connection device (29) for connecting a blanking element (4) of anatomical shape to close off the site of the post-extraction cavity; an upper part (24) comprising a fixing device (304) for fixing a member (9, 100), such as an impression abutment (9) or a prosthetic abutment (100).
