The invention relates to a dental fitting (1, 1', 101, 101', 101") attachable to a dental component (30), such as a dental implant. The dental fitting (1, 1', 101, 101', 101") comprises a main body (2, 2') and a retention element (4, 104, 104', 104") provided apically to the main body (2, 2'). The retention element (4, 104, 104', 104") comprises an attachment portion (6, 106, 106', 106") for attaching the dental fitting (1, 1', 101, 101', 101") to the dental component (30). The retention element (4, 104, 104', 104") has a closed ring shape or an open ring shape in a cross-section perpendicular to the direction from the attachment portion (6, 106, 106', 106") towards a coronal end (8) of the main body (2, 2'). The attachment portion (6, 106, 106', 106") comprises at least one projection (10, 110, 110', 110") extending in one or more directions substantially perpendicular to the direction from the attachment portion (6, 106, 106', 106") towards the coronal end (8) of the main body (2, 2'). The at least one projection (10, 110, 110', 110'') has a coronal surface which is inclined relative to the direction from the coronal end (8) of the main body (2, 2') towards the attachment portion (6, 106, 106', 106'') at an angle of less than 90°. The retention element (4, 104, 104', 104") is integrally formed with or integrally attached to the main body (2, 2').L'invention concerne un appareil dentaire (1, 1', 101, 101', 101") pouvant se fixer à un élément dentaire (30), tel qu'un implant dentaire. L'appareil dentaire (1, 1', 101, 101', 101") comprend un corps principal (2, 2') et un élément de retenue (4, 104, 104', 104") disposé au sommet du corps principal (2, 2'). L'élément de retenue (4, 104, 104', 104") comprend une partie de fixation (6, 106, 106', 106") pour fixer l'appareil dentaire (1, 1', 101, 101', 101") à l'élément dentaire (30). L'élément de retenue (4, 104, 104', 104") a une forme annulaire fermée ou une forme annulaire ouverte dans une section transversale perpend
