An implant support cap extending along a longitudinal axis between ends (14, 16) of the implant support cap, and comprising: a wall defining a cavity and including mating grooves, the mating grooves defining a first longitudinal passageway and a second longitudinal passageway, characterized in that the implant support cap further comprises: a guide including an angled distal surface of wall, engageable with an implant support member including spaced apart extender tabs (152, 152a), the guide further including an extension having a first slot disposed coaxial with the first passageway and a second slot disposed coaxial with the second passageway, the angled distal surface including a first opening communicating with the first passageway and a second opening communicating with the second passageway to orient the tabs (152, 152a) with the passageways (68, 74) such that the implant support member is connectable with the wall, wherein the angled distal surface is disposed at an angle relative to the longitudinal axis such that surface is disposed in a transverse orientation relative to the passageways (68, 74) to define a ramp, wherein the guide, along the ramp, is open in a transverse direction to the longitudinal axis, thereby exposing the first slot and the second slot in the transverse direction to the longitudinal axis. a wall defining a cavity and including mating grooves, the mating grooves defining a first longitudinal passageway and a second longitudinal passageway, characterized in that the implant support cap further comprises: a guide including an angled distal surface of wall, engageable with an implant support member including spaced apart extender tabs (152, 152a), the guide further including an extension having a first slot disposed coaxial with the first passageway and a second slot disposed coaxial with the second passageway, the angled distal surface including a first opening communicating with the first passageway and a second opening communicating with the second passageway to orient the tabs (152, 152a) with the passageways (68, 74) such that the implant support member is connectable with the wall, wherein the angled distal surface is disposed at an angle relative to the longitudinal axis such that surface is disposed in a transverse orientation relative to the passageways (68, 74) to define a ramp, wherein the guide, along the ramp, is open in a transverse direction to the longitudinal axis, thereby exposing the first slot and the second slot in the transverse direction to the longitudinal axis. a guide including an angled distal surface of wall, engageable with an implant support member including spaced apart extender tabs (152, 152a), the guide further including an extension having a first slot disposed coaxial with the first passageway and a second slot disposed coaxial with the second passageway, the angled distal surface including a first opening communicating with the first passageway and a second opening communicating with the second passageway to orient the tabs (152, 152a) with the passageways (68, 74) such that the implant support member is connectable with the wall, wherein the angled distal surface is disposed at an angle relative to the longitudinal axis such that surface is disposed in a transverse orientation relative to the passageways (68, 74) to define a ramp, wherein the guide, along the ramp, is open in a transverse direction to the longitudinal axis, thereby exposing the first slot and the second slot in the transverse direction to the longitudinal axis.
