A system and method of automated formation of a preparation stub, based on an a priori created computational geometrical model, configured to conform to a prefabricated fixed dental prosthesis, is described. The system includes a digital imaging facility with an image acquiring device and a three-dimensional data digitizer, a modeling facility with an exterior surface design module and an interior surface design module, a fabrication facility operatively with a computer-aided manufacturing module, as well as an application facility including an ablation tool and in-situ preparation module; application facility preferably includes an intra-oral feedbacking appliance with a distance measurement probe for automated feedback-controlled formation of a preparation stub.

A protection device for use in oral surgery. The device comprises; a body having a first part which locates outside a patient's mouth and a second part which, during use, locates inside the mouth. The body is arranged such that at least a part of the body is resiliency deformable to enable manual shaping to accommodate an anatomical shape of at least part of a patient's mouth, thereby providing a physical barrier between surgical instrumentation and a patient's soft tissue.

The disclosed apparatus, systems and methods relate to devices, systems and methods relating to a negative pressure face shield comprising a housing defining a lumen, at least one anterior access port defined within the housing, and a suction port defined within the housing.

A film tensioning element is provided for dental applications with a film extending between tensioning rings. The film has a modulus of elasticity of less than 2 KN/mm.sup.2. The film is made of a tough plastic with a modulus of elasticity of more than 1 KN/mm.sup.2, in particular of PP, or optionally of PA. The film tensioning element is manufactured together with the tensioning rings.

A protection device for transoral surgery includes: a main body configured to be fitted into an oral cavity of a human body and to expand a mouth vestibule between teeth and a lip of the human body; and at least one insertion device provided to the main body and having a through hole formed therethrough to enable insertion of a trocar required for a surgery. The main body includes: a tooth coupling part configured to be fitted on the teeth of the human body; an expansion part to be disposed on an outside of the tooth coupling part and configured to expand the mouth vestibule to allow the teeth and the lip to be spaced apart from each other; and an extension part configured to connect the tooth coupling part and the expansion part.
