POROUS IMPLANT DEVICE WITH IMPROVED CORE
An implant device has an exterior portion forming an exterior surface of the implant. The exterior portion is made of a porous material defining passages through the exterior portion. An inner portion has an outer surface with a treated area that is accessible from the exterior surface through the passages. The treated area has a treatment for direct attachment to bone or soft tissue.
SURFACE-MODIFIED HYBRID SURFACE IMPLANT AND METHOD FOR MANUFACTURING THE SAME
The present invention relates to an implant having a nanotube on a surface thereof and a method for manufacturing the same, and more particularly, to an implant having excellent stability and effectiveness because a nanotube is provided on the surface of the implant and a nanocapsule loaded with a medicine or the like is attached to the nanotube, thereby strengthening the adhesive force with the peripheral soft tissue and allowing to stably load factors related to osteogenesis and inflammation prevention and treatment or the like, thus not making them lost during an implant procedure and therefore not only having an increased lifespan but also preventing almost all occurrences of side effects caused by the implant.
SURFACE MODIFICATION FOR ENHANCED BONDING OF CERAMIC MATERIALS
A fluoride treated medical implant, such as a dental component, is provided, the medical implant comprising fluorinated metal oxide on the substrate surface. A method for the preparation of such treated implants is also provided, the method involving exposure of the medical implant to a fluorine-containing reagent. A dental structure is also provided, which includes a first dental component comprising a fluorinated metal oxide layer on its surface, a silane coupling agent, a dental cement, and a second dental component having a surface bonded to the dental cement. An additional dental structure, which includes a first dental component comprising a fluorinated metal oxide layer on its surface, a dental cement, and a second dental component having a surface bonded to the dental cement is also provided.
IMPLANT AND MANUFACTURING METHOD THEREFOR
Provided is an implant including a base material composed of magnesium or a magnesium alloy and an anodized membrane formed on a surface of the base material. The anodized membrane has 8,000 to 250,000 pores with an average diameter of 0.1 m to 1 m within 1 mm.sup.2.
METHOD FOR PRODUCING A SURFACE STRUCTURE ON AN IMPLANT, AND SUCH AN IMPLANT
A surface structure is produced on an outer surface of an implant or a fixture and forms a base structure in a range of implants related to different types and qualities of jaw bone. During production of the surface, parts of a turning tool are placed against the implant or against a blank which is intended to form the implant. The parts and/or the implant are assigned controls which give rise to mutual displacements between the parts and the implant so that the parts follow a substantially spiral trajectory along the outer surface. By means of said controls, a long wave pattern is formed with successive peaks and with through lying between these. In this connection, a through can be arranged adjacent to the outer parts of an existing thread. The controls are chosen so as to produce through depths in the range of 25 to 250 m, preferably 50 to 200 m. The invention also relates to an implant which bas the same character as the implant produced by the method.
Implant body, method of manufacture of same, and dental implant
To obtain improved bio-affinity and high bone attachment in an implant body, a method of manufacture for the implant body, and a dental implant. The implant body is fixed in a contact configuration to bone, and includes the base material formed from zirconia, and a surface layer formed on the surface of the base material and having a lower hardness than the base material. Therefore, in addition to having superior mechanical strength due to the zirconia base material, the soft and flexible surface layer functions as a buffer layer to mitigate the difference in the degree of hardness between the bone and the base material, and therefore the soft surface further improves the bone adhesion characteristics.
Deposition of discrete nanoparticles on a nanostructured surface of an implant
A method of forming an implant to be implanted into living bone is disclosed. The method comprises the act of roughening at least a portion of the implant surface to produce a microscale roughened surface. The method further comprises forming a nanoscale roughened surface on the microscale roughened surface. The method further comprises the act of depositing discrete nanoparticles on the nanoscale roughened surface though a one-step process of exposing the roughened surface to a solution including the nanoparticles. The nanoparticles comprise a material having a property that promotes osseointegration.
DENTAL IMPLANT, COMPONENT FOR DENTAL APPLICATIONS, IMPLANT SYSTEM FOR DENTAL APPLICATIONS, METHOD FOR FORMING A PROTECTIVE LAYER ON THE SURFACE OF AN IMPLANTABLE OR IMPLANT COMPONENT, IMPLANTABLE OR IMPLANT COMPONENT HAVING A PROTECTIVE LAYER, AND USE OF A PROTECTIVE LAYER
