摘要：
A frictionally-retained detachable dental attachment assembly or anchor device is designed to attach a dental appliance with a tooth root or implant. The assembly includes a denture attachment housing for securing in the dental appliance, an abutment attached with a tooth root or implant, and a compressible retention member with a first end in fixed attachment with the cap and a second end in snap engagement with the abutment via a frictionally-retained ball secured within a cavity of the abutment. The retention member is formed using a compressible material to allow the ball to compress and the retention member to flex while inserting the ball into the cavity. Additional friction-retained and fixed attachment configurations of the dental anchor device are provided, along with methods of securing a dental appliance in a subject's mouth by means of the friction-retained and fixed attachment dental anchor devices.
