摘要:
Most surgical implants today require a two stage surgical protocol for placement of the implant. The procedure is time consuming, expensive and requires extensive technical skill. It can also be possible to place the dental implant directly into an extraction socket but requires deeper drilling. Many general dentists often don’t carry out such procedures due to the risk and high skill level required. The disclosure is directed to a dental device comprising: a dental implant comprising a core enveloped by an expandable anchor comprising a plurality of joined segments. Prior to insertion of the core into the expandable anchor a carrier apically displaces within the expandable anchor, generating an expansion force causing the plurality of joined segments to be displaced away from the central axis of the implant where the coronal and apical ends of each joined segment are displaced in parallel paths normal to the central axis of the implant. The core inserts into the expandable anchor to lock the plurality of joined segments in their expanded configuration. The carrier is used to generate an expansion force to expand the segments normal to the central axis of the implant. By displacing the segments normal to the central axis of the implant by the carrier and then inserting the core into the expanded segments, torque exerted by the dental implant on the tooth socket during installation is decreased, which reduces the risk of damage to the tooth socket due to excessive torque and/or unwanted fixture rotation, to make the surgical procedure for placement of the implant easier.
