Claim:
1. An implantable dental device comprising: a root member for implantation into a cavity in either alveolar bone or a root canal space of a tooth, wherein the root member includes at least one first portion comprising a polymeric shape memory material defining a collar portion which encapsulates an internal support structure, at least one second portion comprising a non-shape memory material, and an abutment mount for receiving a dental prosthesis, wherein the collar portion defines a non-threaded outer surface extending from the at least one second portion to the abutment mount, the polymeric shape memory material is activatable from a deformed state to a relaxed state upon input of energy to the polymeric shape memory material, wherein the deformed state is sized and shaped for insertion into the cavity, wherein the relaxed state has a size and shape that is laterally expanded relative to the deformed state for sealing engagement of the non-threaded outer surface of the collar portion with an inner wall of the cavity adjacent the abutment mount to thereby anchor the root member in position and to provide a seal between the root member and the inner wall of the cavity.
