Fixed hybrid dental attachment assembly and methods of use

A dental attachment assembly, comprising:

• an abutment member with a first end shaped to attach to a tooth root, implant or adjacent tooth, and a second end with an outer locating surface, wherein the outer locating surface of the abutment member has at least two axially spaced retention portions comprising two generally rounded, annular projections;
• a first retention member having a first end and a continuous, unbroken skirt extending from the first end defining an inner surface for fixed, non-patient removable 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 about 10 to 75 pounds, such that upon engagement over the outer locating surface of the abutment member, the retention member is non-patient removable from the abutment member, wherein the first retention member has 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, and wherein the axially spaced, snap engaging formations on the inner surface of the skirt comprise two spaced, annular grooves for snap engagement over the annular projections on the abutment member, and wherein the rigid material comprises polyetheretherketone (PEEK);
• and
• wherein the abutment member is sized and dimensioned for engagement with a second retention member made of a more resilient material than the first retention member and having a second end and a continuous, unbroken skirt extending from the second end defining a second inner surface for patient removable engagement over the outer locating surface of the abutment member,
• a cap with a rounded, concave inner surface defining a cavity to receive the retention member;
• wherein the cap is configured for securing in a dental appliance.
