A dental implant made of a material comprising titanium. The implant includes a head portion having a non-rotational feature, a lowermost end opposing the head portion, and a threaded bottom portion for engaging bone between the head portion implant and the lowermost end. The implant further includes a nanocrystalline surface formed on at least a portion of the implant. The nanocrystalline surface includes discrete nanocrystals deposited on a roughened surface of the implant. The roughened surface includes at least one of a grit-blasted surface or an acid-etched surface. A portion of the roughened surface is exposed between at least some of the discrete nanocrystals such that the exposed roughened portion between the discrete nanocrystals is capable of contacting bone.

Provided is a medical device including a porous portion and a dense portion, wherein an arithmetic average roughness of a surface of the porous portion is 2.0 μm or greater but 20 μm or less, and wherein an arithmetic average roughness of a surface of the dense portion is less than 2.0 μm.

A dental implant unit includes a layer of synthetically created titanium dioxide. The dental implant unit has one end for connection and a lateral surface covering the implant unit except for the end for connection. The lateral surface includes a layer of synthetically created titanium dioxide while the end for connection is free from synthetically created titanium dioxide. Also, a method produces a whitened implantable dental unit. The method includes thermal oxidation of a dental implant unit that includes titanium.

The invention features bone screws having a threaded screw body and a screw head attached to one end of the screw body, the bone screw further including: a) an interior channel extending longitudinally through the screw head and through at least a portion of the screw body, wherein the interior channel has a width of less than 5.0 millimeters; and b) a plurality of radially-disposed delivery channels connecting the interior channel to the exterior of the screw body, each delivery channel having exterior openings. The invention further features devices that include a bone screw and a delivery manifold detachably attached to the screw head of the bone screw. In addition, the invention features methods of treating a patient having a bone defect by using a bone screw described herein.

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.

A bone foundation guide system has a bone foundation guide including a body that is contoured to reversibly affix to a bone segment of a dental implant surgical site. The body is further contoured to guide the cutting of a portion of the bone segment from a dental implant surgical site and alternatively support a dental implant surgical guide. The body is further contoured to support a bone foundation guide prosthesis as an alternative to the dental implant surgical guide. The bone foundation guide prosthesis combines with the body to accommodate the bone segment portion as placed through the body prior to the bone segment portion being removed from the dental implant site through the use of the body.

A dental implant supported on the cortical bone is implanted in the socket from which the tooth was extracted, if this hole still exists, or in the remaining socket when the tooth was extracted some time before, or alternatively in a hole made for placement of the implant, at cortical bone level, and externally, between the cortical bone and the gingiva, slightly embracing the mandible and the maxilla.

In one embodiment, in order to enhance the fixation and implant lifetime vascularization, the implant of the present disclosure for fitting in an intraosseous zone of a dental socket includes a plurality of raised platforms with a flat top such that said tops form an external surface of the implant for contacting with the intraosseous zone and the spaces between said platforms form a network of channels for revascularisation fluid flow with capillarity properties.

A scaffold (12) for tissue engineering comprises an inner portion (14), an outer portion (16), and a base portion (22) connecting the inner portion and the outer portion. The inner portion (14) comprises a channel (18) surrounded by a first set of one or more walls. The outer portion (16) comprises a second set of one or more walls. The portions are arranged such that the second set of one or more walls substantially surrounds the first set of one or more walls with a spacing between the first and second sets of walls defining a cavity (20) between the inner portion (14) and the outer portion (16). The inner portion (14) and the outer portion (16) may have different shapes; and/or the scaffold (12) may further comprise a filler material in the cavity (20) defined between the inner and outer portions.

The present disclosure relates to a method of manufacture of a dental implant for a molar, including acquiring, structural data corresponding to bones of the facial skeleton, the bones of the facial skeleton being proximate the molar, selecting, as a dental implant fixation surface, a surface of the bones based upon a determined thickness of the bones, generating, based on the selected dental implant fixation surface, a contoured surface of the dental implant, and fabricating, based upon an instruction transmitted by processing circuitry, a bone plate extending from a buccal end of a cylindrical plate of the dental implant, the cylindrical plate having support lattices extending therefrom, at least one support lattice of the support lattices being arranged on a lingual end of the cylindrical plate, the cylindrical plate having an opening in a central region thereof, the opening being configured to receive a dental post.
