Part of the printed human tooth structure is rooted in the printed human jaw structure, and both structures are designed to have at least one analogous physical property to their corresponding human structures. The self-assessment includes a pictorial array of procedural outcomes of a procedural step so that a user can identify which image in the pictorial array best represents the user's own procedural outcome of the procedural step performed by the user on the training device and at least one feedback instruction.

The present innovation relates to an Advanced Training System Mannequin Simulators of a complete newborn baby with facial and intraoral features of the CLP malformation, AMACS. It is intended for use in medical training of dental professionals, doctors, emergency medical support personnel and parents or caregivers. Furthermore, it can be adopted in several common therapies and in maneuvers such as intraoral impressions. It can also be used by any other person who requires a model simulator to learn the anatomy, practice procedures or surgery of the lip, nose and palate. The invention avoids unsettling a real newborn patient for training proposes. This mannequin simulator, as an innovative training resource, significantly shortens the learning curve of the trainees, since the procedures can be repeated over and over again. The AMACS comprises: (a) trunk and limbs, having as reference the weight and height of a real newborn, (b) a complete head (skull, face and neck), having as reference the facial and intraoral features of the CLP malformation, (c) the anatomy of the lips, nose, oral and nasal cavities with the actual dimensions and proportions of a newborn with CLP deformity. The most remarkable feature is a very accurate representation of the entire body but, in particular, the oral and facial anatomical features of a newborn with CLP deformity, thus allowing for a high-level and realistic training experience. In the facial and intraoral region of the mannequin the lips, tongue, cheeks, maxillary segments, palatal rugae, labial and lateral frenulum, nasal cavity, palate, hemi uvulae, tongue and lingual frenulum, columella, nostrils, alar cartilage, dome and nasal tip are faithfully reproduced. On the outer surface of the mannequin the skin, the route of the veins, the relief of the ribs and clavicles are also scrupulously represented. The mannequin may include the alteration of one or more anatomical parts to simulate the different types of congenital anomalies that affect the facial and intraoral region. One or more parts of the mannequin simulator may be disposable or replaceable. The careful design of the AMACS follows the process of: (a) computed tomography, scan, or photogrammetry images of the full skull and face of a human newborn with CLP; (b) generating the cleft lip and palate based on a three-dimensional reconstruction of the buccal area. The manufacture process involves methods independent and indispensable but not in sequence: (a) parts made by injection of polymer-based material; b) parts made by 3D printing, and (c) assembly. Both body and head are perfectioned using realistic painting techniques.

The present disclosure is directed to a system and method for surgical training with low cost, reusable materials and a highly customizable virtual environment for skill-building. According to various embodiments, a surgical training tool is usable in conjunction with a support structure configured to at least partially constrain the tool movement. Meanwhile, the tool is tracked in real-time with off-tool detectors to generate a tool path driving a virtual rendering of the surgical training tool in an operative environment. The virtual rendering may be visually observable via a display device and may include a customizable and/or selectable operative environment with one or more structures that can be operated on by the virtual surgical training tool. By tracking the virtual tool interaction with the virtual structures, a task path may be established for documenting and/or objectively assessing the performance of one or more operative tasks.
