A dental assembly is provided, which includes an endosseous dental implant, a retention member, and a cap configured for securing in a dental appliance and engaging the retention member. The endosseous dental implant may have an external projection extending from the top of the first end portion for releasable engagement with an abutment member, wherein the abutment member has an external lower bevel portion. The retention member may have a first end and a continuous, unbroken skirt extending from the first end defining an inner surface for engagement over the outer locating surface of the abutment member, the retention member being constructed from a rigid material such that it provides a retentive force of abouttopounds. The rigid material may include PEEK.

Fixed hybrid dental attachment assembly and methods of use

A fixed hybrid dental attachment assembly is provided. The fixed hybrid dental attachment assembly includes an abutment member, a male member, and a cap. The abutment member has an outer locating surface portion projecting downwardly from an upper end. The male member for attachment to the abutment member has an upper end for engagement within a cap in a recess in a dental appliance, and a continuous, unbroken skirt projecting from the upper end of the male member for engagement over the outer locating surface of the abutment member. The skirt may have a rounded, convex outer surface, and the male member may be constructed from a PEEK material.

A dental attachment assembly is provided, including an abutment member and a male member. The abutment member may include an outer locating surface portion having at least two axially spaced retention portions having two generally rounded, annular projections. The male member for engagement over the outer locating surface of the abutment member may include an upper end and a continuous, unbroken skirt having a rounded, convex outer surface. The male member may be constructed from a rigid material and have at least two axially spaced, snap engaging formations on the inner surface of the skirt for snap engagement with the respective retention portions of the abutment member.

An exemplary apparatus for connecting surgical rods according the principles of the present disclosure includes an elongate first arm, an elongate second arm, and a clamping assembly. The elongate first arm includes a first end that couples with a first rod and a second end with a first engagement portion. The elongate second arm includes a first end that couples with a second rod and a second end terminating in a second engagement portion. The clamping assembly includes a passageway that slidably receives the first engagement portion and that retains the second engagement portion and an adjustment member offset from the passageway that adjusts a clamping force to restrict positioning of the second engagement portion relative to the first engagement portion.

Apparatus and method for connecting surgical rods

An instrument for breaking off and retaining the tab of a reduction screw is provided. The instrument includes a breaking arm and a retaining mechanism. The breaking arm is configured to break off an excess portion of the tab of the reduction screw about a weakened section. The retaining mechanism is configured to retain the broken off tab and preventing the tab from falling into a surgical site. The retaining mechanism is further configured to allow the instrument to engage another tab while simultaneously holding a predetermined number of previously broken off tabs. Accordingly, the instrument reduces surgical time as the surgeon may simply move from one reduction screw to another while breaking off the tabs until the instrument can no longer retain additional broken off tabs.
