DENTAL IMPLANT
A dental implant adapted for implanting within a jaw bone, the implant comprising a horizontally-oriented body having a length extending in the mesial-distal direction of the jaw bone, the body having a threaded cavity dimensioned for receiving a prosthetic abutment, and wherein the cavity comprises an opening that is located wholly within a buccolingual width of the body.
ROOT IMPLANT
A root implant includes a body portion, a drilling portion formed on the body portion, a positioning hole formed opposite to the drilling portion, and a thread portion spiraled on the body portion. The body portion and the coarse thread have respective first openings and second openings spaced apart by equal distances. The first openings and second openings accommodate accretions grown from the alveolar bone when the root implant interfaces with the alveolar bone. The body portion and the coarse thread includes first joint sections and second joint sections formed between any two of the first openings and the second openings respectively to allow the accretions to clamber and link together to provide a tight combination between the root implant and the alveolar bone, preventing the loosening problem caused by an external force and promoting a positioning effect of the root implant.
CUSTOMIZED POROUS SUPRACRESTAL IMPLANT AND MATERIALS AND METHODS FORMING THEM
The present invention generally relates to osseointegrated implants. In particular, embodiments of the present invention relate to extraosseous implants, for example, supra crestal implants, that are configured to substantially continuously cover the 3D topography of a top and a lateral surface of a bone, for example, a crestal and a lateral surface of the jaw. For example, the implants may be used on partially or completely edentulous jaws. Also, embodiments of the present invention relate to such implants made from biocompatible material of suitable porosity and elastic modulus. Specifically, embodiments of the present invention relate to improved implants suitable for implantation to bone deficient in quantity or quality, such as severely resorbed jaw bone. Further embodiments relate to a unique composite material comprising PEEK, bioglass and PMMA, and formed using triacrylate.
Prosthetic element for bone extremities such as fingers or toes, or for teeth, and corresponding production method
Prosthetic element for bone extremities such as fingers or toes, or teeth, comprising a trabecular part (20, 40, 120) and two end parts or stumps (12, 34, 112; 15, 39, 115).
DENTAL TITANIUM MATERIAL HAVING MODIFIED SURFACE, AND PREPARATION METHOD THEREFOR
The present invention relates to a dental titanium material having a surface modified through plasma treatment; an implant; and a preparation method therefor. The titanium material and the implant prepared according to the present invention have improved cell adhesion and antimicrobial effect so that biocompatibility is improved and the inflammatory response of a user and the like can be minimized.
METHOD FOR MANUFACTURING AN 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, ?-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.
Additive manufactured dental implants and methods thereof
A monolithic dental implant formed from an additive manufacturing method can include a non-porous portion and a porous structure. The porous structure can increase osseointegration of the dental implant and increase the secondary stability.
DEPOSITION OF DISCRETE NANOPARTICLES ON AN IMPLANT SURFACE
A method of forming a nanocrystalline surface on an implant is disclosed. The method comprises the act of roughening at least a portion of the implant surface to form a roughened surface. The method further comprises the act of, without forming an alkoxide on the roughened surface, depositing nanocrystals on the roughened surface. The nanocrystals comprise a material having a property that promotes osseointegration.
DENTAL IMPLANT HAVING ENHANCED EARLY STABILITY AND METHOD FOR MANUFACTURING SAME
A dental implant and a method for manufacturing same which assure early stability and fixation power of an implant by suppressing early osteolysis after an implant procedure, and allowing better bone coherence of the implant surface during an osteogenic period by controlling the speed of bone remodeling.
DENTAL IMPLANT
An implant, particularly a dental implant is provided, having an anchoring region (12) for anchoring in a bone, which preferably includes a thread (14) for screwing in the bone, and a fastening region (22) for attaching a supra-construction, wherein an abutment region (16) adjoins the anchoring region (12), the abutment region (16) having a guide structure with a plurality of outwardly projecting ridges (18) provided thereon, and preferably, grooves (20) being formed between the ridges (20). The guide structure of the anchoring region (12) allows a better osseointegration and counteracts periimplant bone loss.
