摘要:
A self-tapping dental implant for implantation into bone. The implant includes multiple flutes disposed around the tapping end. Each flute has a helical configuration. During tapping, bone chips are directed upwardly and away from the tapping end.
摘要:
A dental implant system that dramatically simplifies implantation of a dental implant at an implant site. The dental implant system includes a threaded dental implant having a mounting end with an internal, threaded, axial bore. A healing cap is threadably engaged with the internal, axial bore prior to implantation. The healing cap also includes engagement features, such as a plurality of indentations, that permit secure engagement of a dental driving tool with the healing cap. Thus, upon engagement with a dental driving tool, the dental implant system can be threaded into engagement with the alveolar bone at the implant site and covered by gingival tissue, without any additional components or process steps.
摘要:
A device for retaining and delivering dental implant components includes a retainer-delivery member which may be pivotally attached to a handle member and selectively detached therefrom. The retainer-delivery member has a plurality of multi-sized stepped down portions for hands-off insertion into, and frictional engagement with various dental implant components. The retainer-delivery member can retain one or more of the components for delivery to the implant site and can be manipulated for initial connection to the implant.

A patient-specific bone implant has a porous body with a core material covered with tantalum. It is made with unique outer dimensions selected to match a specific patient.
摘要:
Disclosed within is a dental restorative system including a dental fixture component having a longitudinal axis, a body portion, and an emergence profile portion adjacent to the body portion. The dental fixture component also has a tapered coronal portion adjacent to the emergence profile portion, with the tapered coronal portion having one end adjacent to the emergence profile portion and a terminal end with a non-frustoconical surface and a non-circular cross section. The emergence profile portion may include one or more concave surfaces. The dental fixture component may further include an interproximally sloping margin shoulder. Certain embodiments of the dental fixture component include threaded body portions. Alternative embodiments of the dental fixture component are also disclosed.
摘要:
Dental implants made at least in part of a highly porous biomaterial such as porous tantalum for enhancing the osseointegration of the dental implant into surrounding bone. For example, there is provided a dental implant which includes a core formed of with a head portion having an abutment interface and a stem portion extending from the head portion. A porous tantalum sleeve is disposed about the stem portion and occupies a substantial portion of the implant/bone interface of the implant. After implantation of the implant, bone tissue may osseointegrate into the porous tantalum sleeve to anchor the implant in position within the surrounding bone. Other embodiments of implants are provided, each implant including at least a portion thereof formed of porous tantalum for improved osseointegration.
摘要:
A composite interbody vertebral implant for facilitating fusion of adjacent vertebrae. The implant includes a first endplate of a porous metal material and a second endplate of a porous metal material which are configured to allow bone in-growth. The implant also includes a polymeric body positioned between and bonded to the first and second endplates such that polymeric material of the polymeric body is impregnated into pores of the first and second endplates to bond the components together. The implant may include a cavity extending through the composite implant configured to receive bone growth material to facilitate fusion between a first vertebra and a second vertebra.
摘要:
Disclosed within is a dental restorative system including an impression coping with a body portion having a first end, a second end, and an internal chamber having non-frustoconical side walls. The body portion also has a facial aspect and a lingual aspect and the distance between the first end and second end on the facial aspect is greater than the distance between the first end and second end on the lingual aspect. The first end of the impression coping may include an opening and an interproximal, continuous slope. Certain embodiments of the impression coping include means for engaging an abutment or implant, located on the internal chamber. Other embodiments include external flange portions for retention of the coping in impression material. Alternative embodiments of the impression coping are also disclosed.
