Flexible abutment for use with dental implant

An abutment for use in combination with a dental prosthesis and with a dental implant configured for implantation in an osseous structure, the abutment comprising:

• an abutment wall having an outer surface and an inner surface, the inner surface defining a longitudinally extending abutment channel configured to receive a retention assembly therein to engage the abutment with the dental implant;
• and
• a flexural region defined by the abutment wall and forming a monolithic structure with a remainder of the abutment, the flexural region comprising:
• a shoulder portion extending outwardly such that the abutment has a widest outer diameter at the shoulder portion;
• and
• an abutment recess located below the shoulder portion when the abutment is in an upright position, the abutment recess defining a reduced outer diameter of the abutment compared to the shoulder portion, each one of the shoulder portion and the abutment recess extending along at least a portion of a circumference of the abutment wall;
• the inner surface of the longitudinally extending abutment channel defining an abutment cavity at the shoulder portion, the abutment cavity remaining as a void once the abutment is engaged with the retention assembly:
• wherein the longitudinally extending abutment channel has a diameter that is larger at the shoulder portion than at the abutment recess;
• and
• wherein the flexural region is configured to enable at least a vertical movement of an upper portion of the abutment relative to a lower portion of the abutment when the abutment is subjected to a loading force during mastication.
