“…The convergence of haptics and virtual reality technology and integration with 3D imaging data resulted in the emergence of dental haptic simulators. Created virtual oral anatomy and facilitated the simulation of dental procedures offer real-time visual, tactile and auditory planning as well as feedback [ 67 , 68 ]. Combination of haptic instruments with 3D printing contributed towards the development of patient-specific instrumentation, in particular, surgical guide instruments that increase accuracy during surgery while decreasing the risk of infections and operation time/cost.…”

Three-dimensional (3D) printing technology allows the production of an individualized 3D object based on a material of choice, a specific computer-aided design and precise manufacturing. Developments in digital technology, smart biomaterials and advanced cell culturing, combined with 3D printing, provide promising grounds for patient-tailored treatments. In dentistry, the “digital workflow” comprising intraoral scanning for data acquisition, object design and 3D printing, is already in use for manufacturing of surgical guides, dental models and reconstructions. 3D printing, however, remains un-investigated for oral mucosa/gingiva. This scoping literature review provides an overview of the 3D printing technology and its applications in regenerative medicine to then describe 3D printing in dentistry for the production of surgical guides, educational models and the biological reconstructions of periodontal tissues from laboratory to a clinical case. The biomaterials suitable for oral soft tissues printing are outlined. The current treatments and their limitations for oral soft tissue regeneration are presented, including “off the shelf” products and the blood concentrate (PRF). Finally, tissue engineered gingival equivalents are described as the basis for future 3D-printed oral soft tissue constructs. The existing knowledge exploring different approaches could be applied to produce patient-tailored 3D-printed oral soft tissue graft with an appropriate inner architecture and outer shape, leading to a functional as well as aesthetically satisfying outcome.

“…Haptics is a science pertaining to the sense of touch and its interaction with the virtual environment. Haptic devices linked with virtual reality simulation systems, haptic simulators, stimulate a sensory tactile experience through real-time robotic feedback systems capable of generating vibrations and counter-forces [15,69]. Most haptic devices provide 6 degrees of freedom (DOF) for spatial location but 3 DOF for force feedback, which limits realism.…”

“…The convergence of haptic and virtual reality technology and integration with 3D imaging data in dentistry had resulted in the emergence of dental haptic simulators that can create virtual oral anatomy, and facilitate simulation (3D virtual planning) of dental procedures with real-time visual, tactile, and auditory feedback [15,70]. Thus, these devices are primarily used in dental education for 3D virtual planning [71].…”

“…The automated processes involve devices (3D printers), which utilise various 3D printing techniques to fabricate objects [14]. Haptic simulators are computer systems that create interactive 3D virtual simulations of teeth and skeletal tissues by mimicking likely challenges of various treatment procedures and providing real-time multi-sensory perioperative feedback [15]. The design and production of 3D printed objects and operation of haptic simulators rely on the exchange of digital information (data) between 3D imaging, 3D virtual planning and/or 3D printing technologies.…”

The adoption and adaptation of recent advances in digital technology, such as three-dimensional (3D) printed objects and haptic simulators, in dentistry have influenced teaching and/or management of cases involving implant, craniofacial, maxillofacial, orthognathic and periodontal treatments. 3D printed models and guides may help operators plan and tackle complicated non-surgical and surgical endodontic treatment and may aid skill acquisition. Haptic simulators may assist in the development of competency in endodontic procedures through the acquisition of psycho-motor skills. This review explores and discusses the potential applications of 3D printed models and guides, and haptic simulators in the teaching and management of endodontic procedures. An understanding of the pertinent technology related to the production of 3D printed objects and the operation of haptic simulators are also presented.

The central Tauern Window and the adjacent Austroalpine Unit are characterized by complex tectonic, geological and geomorphologic settings that result in a variety of different hillslope processes. Most scientific studies in the literature about slope instabilities in the Tauern Window focus on single slopes only. The present work is a first attempt, to give a regional overview about gravitational mass movements and predispositional factors, which are typical for the Sub-Penninic, Penninic and Austroalpine units. The varying anisotropy in rock material caused by a highly diversified foliation and the presence of brittle fault zones affects the stability of the slopes within the study region significantly, thus leading to spatial pattern of different types of gravitational mass movements. Mountain slope deformations are the most characteristic morphologic feature and occur throughout the study area. The Sub-Penninic and Penninic units show a higher susceptibility of to rockslides and mountain slope deformations in the southwest dipping slopes. TheUpper Austroalpine sub-unit is more susceptible to rockfalls in addition to mountain slope deformations. The Lower Austroalpine sub-unit is primarily susceptible to mountain slope deformations, the dominant mechanism being creep. Some areas of the slopes are covered by moraine deposits or scree due to the glacial and postglacial landscape evolution. Rockfall activity, due to the remobilization of boulders caused by erosion processes, mass movements or wind throw, is a common process. Such "secondary"
