Abstract: Oral cavity model and manufacturing method manufactured by 3D printing, milling and/or sintering that incorporates the connection of a patient's dental implant and enables it to be used without traditional or digital replicas. The oral cavity model preferably incorporates an internal channel and can incorporate a retaining body used in some embodiments of the oral cavity model, and which has the geometry of the internal orifice or channel of the oral cavity model and an element with an internal thread (used in some form of embodiment) for patients with dental implants and without using traditional or digital replicas. A manufacturing method for oral cavity models by machining, preferably 3D printing, milling and/or sintering, which incorporate or integrate the connection of a dental implant placed in a patient without the need for replicas, whether traditional or digital.
