HIGH STRENGTH INTRAOSSEOUS IMPLANTS
The present invention enables modification of an intraosseous implant device that is not only biologically non-inert, but can stimulate bone and vascular growth; decrease localized inflammation; and fight local infections. The method of the present invention provides a fiber with any of the following modifications: (1) Nanofiber with PDGF, (2) Nanofiber with PDGF+BMP2, and (3) Nanofiber with BMP2 and Ag. Nanofiber can be modified with other growth factors that have been shown to improve bone growth and maturation—BMP and PDGF being the most common. Nanofiber can be applied on the surface of the implant in several ways. First, a spiral micro-notching can be applied on the implant in the same direction as the threads with the nanofibers embedded into the notches. Second, the entire surface of the implant may be coated with a mesh of nanofibers. Third, it can be a combination of both embedding and notching.
Dental implant system having enhanced soft-tissue growth features
A dental implant system including an implant and an abutment is disclosed. The implant includes a generally cylindrical body, a central axis, a distal end for anchoring in a patient's bone and a proximal end opposing the distal end. The proximal end includes a roughened lateralized surface that surrounds an abutment-engaging region. The lateralized surface is disposed at a negative slope relative to the central axis. The abutment includes an upper portion for supporting a tooth-like prosthesis and a lower portion for engaging the abutment-engaging region of the dental implant. The diameter of the lower portion of the abutment is smaller than the diameter of the implant at its proximal end. The lower portion includes a first surface with a soft-tissue enhancing material. The first surface and the lateralized surface defining a circumferentially extending recess having a V-shaped cross-section for receiving and attachment to the soft tissue.
BODY MADE OF TITANIUM OR A TITANIUM ALLOY HAVING A TOPOGRAPHY FOR IMPROVED BLOOD COAGULATION AND/OR CELL ATTACHMENT
A body made of titanium or a titanium alloy having a topography for improved blood coagulation and/or cell attachment. The body is obtainable by a process that includes the subsequent steps of: a) etching at least a portion of the surface of the body with a first etching solution including a mineral acid, and b) etching the surface etched under a) with a second etching solution different than the first etching solution, the second etching solution including hydrofluoric acid.
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.

Implant with enhanced osteoinductivity
An implant device configured to be at least partially in contact with bone on implantation has an improved osteoinductive feature to enhance new bone formation. The implant device has one or more bone growth surfaces extending from a structurally solid feature of the implant device. The one or more bone growth surfaces are configured to mimic adult trabecular bone by having trenches, grooves or surface recesses or prominences exhibiting numerous structural elements or walls not perpendicular to the surface that are non-coplanar or arched extending 20 to 500 microns in depth having an increasing inclination from the surface extending inwardly and not parallel to opposing or adjacent walls forming a random or non-random network. The one or more bone growth surfaces configured to mimic trabecular bone have discernable nano features on the structural elements or walls exhibiting nano scale features of less than 200 nano meters within the network.
Surface topographies for altering the physiology of living cells
The invention pertains to surface topographies which can be used to modulate the morphology, proliferation, biochemical functioning, differentiation, attachment, migration, signaling, and/or cell death of a cell population by physical stimulation. Such topographies can be applied in vitro and in vivo to modulate cell behavior. Specific examples include implants provided with a topography of the invention which regulates the immune response, or an implant which increases osteogenesis. The invention furthermore pertains to objects which are used in vitro to modulate cell behavior.
DEVICES AND METHODS OF TREATING ORAL TISSUES
A device and method for accelerating the conversion of oral bone graft to alveolar bone following extraction in a patient includes a vibrational dental device having a mouthpiece for contacting the dentition. Instructions are provided for using the vibrational dental device by placing the mouthpiece over the dentition, applying a vibratory force during a predetermined number of sessions throughout a predetermined treatment period, wherein the conversion of bone graft material to mature bone is enhanced and/or accelerated compared to without vibratory treatment.
METHOD FOR VIBRATION ENHANCED ALVEOLAR AUGMENTATION
A novel method for extra-alveolar vertical augmentation utilizing bone graft and low-magnitude high-frequency vibration. Graft material is placed at an extra-alveolar location along the alveolar ridge. The graft can be used alone or formed into a PRF block to help it maintain volumetric shape during the initial healing process. After insertion into the surgical site, the graft can be covered by a barrier, for example a bioactive amnion/chorion barrier. The flaps are then sutured to attempt to obtain primary closure over the graft and barrier. Low-magnitude high-frequency vibration is applied, resulting vertically augmented alveolar bone.
IMPLANTABLE OBJECTS, GUIDING DEVICES, AND METHODS OF USE THEREOF
Embodiments of the disclosure relate to implantable objects and guiding devices, as well as recipient site preparation instruments, bone-implantable materials, and methods of fabrication and use thereof.
