The invention relates to a dental fitting (1) attachable to a first dental component (30), such as a dental implant, and to a second dental component (40), such as a dental prosthesis. The dental fitting (1) comprises a main body (2) and an attachment member (4) which is at least partly received within the main body (2). The dental fitting (1) is configured so that movement of the attachment member (4) relative to the main body (2) along a longitudinal axis of the main body (2) is restricted in the apical and coronal directions. The attachment member (4) and the main body (2) are securely aligned with each other so that the longitudinal axis of the main body (2) is substantially parallel to a longitudinal axis of the attachment member (4). An apical portion of the main body (2) is attachable to the first dental component (30). A coronal portion of the attachment member (4) has a threaded section (6) for attaching the dental fitting (1) to the second dental component (40). The dental fitting (1) comprises an attachment element (8) for attaching the dental fitting (1) to the first dental component (30). The attachment member (4) and the attachment element (8) are separate components. The invention further relates to a dental assembly comprising the dental fitting (1) and a first dental component (30) and/or a second dental component (40).L'invention concerne un appareil dentaire (1) pouvant se fixer à un premier composant dentaire (30), tel qu'un implant dentaire, et à un second composant dentaire (40), tel qu'une prothèse dentaire. L'appareil dentaire (1) comprend un corps principal (2) et un élément de fixation (4) qui est au moins partiellement logé à l'intérieur du corps principal (2). Le corps principal (2) est configuré de telle sorte que le mouvement de l'élément de fixation (4) par rapport au corps principal (2) le long d'un axe longitudinal du corps principal (2) est limité dans les directions apicale et coronaire. L'élément de fixation (4) et le corps princi
