“…To the authors' knowledge, very few prior studies exist on bone-sawing simulators [12][13][14][15][16]. Sohmura et al [12] developed a simulation of orthognathic surgery using a virtual reality haptic device. The major use of this study was to determine the optimal repositioning of separated bones using a virtual cutting tool with a long, wide blade.…”

Bone sawing is widely used in orthognathic surgery to correct maxillary deformities. Successful execution of bone sawing requires a high level of dexterity and experience. A virtual reality (VR) surgical simulator can provide a safe, cost-effective, and repeatable training method. In this study, we developed a VR training simulator with haptic functions to simulate bone-sawing force, which was generated by the experimental force model. Ten human skulls were obtained in this study for the determination of surgical bone-sawing force. Using a 5-DOF machining center and a micro-reciprocating saw, bone specimens with different bone density were sawed at different feed rates (20, 40, and 60 mm/min) and spindle speeds (9800, 11,200 and 12,600 cycles per minute). The sawing forces were recorded with a piezoelectric dynamometer and a signal acquisition system. Linear correlation analysis of all experimental data indicates that there were significant positive linear correlations between bone-sawing force and bone density and tool feed rate and a moderate negative linear correlation with tool spindle rate. By performing multiple regression analysis, the prediction models for the bone-sawing procedure were determined. By employing Omega.6 as a haptic device, a medical simulator for the Lefort I osteotomy was developed based on an experimental force model. Comparison of the force-time curve acquired through experiments and the curve computed from the simulator indicate that the obtained forces based on the experimental force model and the acquired data had the same trend for the bone-sawing procedure of orthognathic surgery.

“…The examiner used a haptic VR system, as the measurement could be made using the virtual bur and adjacent teeth. The participant ID (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) was used with random order. All tooth surfaces (incisal, facial, mesial, distal and lingual) were evaluated and graded using three evaluation parameters -depth, inclination, smoothness -as assessment criteria.…”

“…Several VR programs have been developed to simulate surgical procedures such as the navigation of endoscopes, 4 a surgical simulator for planning and performing repair of cleft lips, 5 a simulation of orthognatic surgery. 6 Virtual reality is a sophisticated technique for realizing an experience by supplying variable 3D images by computer graphics. In particular, the haptic interface is the cutting edge technology.…”

“…However, it is worth mentioning here that haptic interfaces for virtual environments, which provide the surgeon with a "feeling" he or she would have when handling physical tissue, are already available and their development and improvement are currently on going. 12,63 When computer aided manufacturing (CAM) techniques were first introduced to the medical field, it became possible to extract geometric information from CT scan images to manufacture physical biomodels. 4,6 Now the surgeon could prepare, simulate, and assess surgical procedures, with normal surgical tools, on a reproduction of the actual anatomy of a living person.…”

In this paper, a definition of a biomodel is presented, based on which different specific types of biomodels are identified, viz., virtual biomodels, computational biomodels, and physical biomodels. The paper then focuses on both physical and virtual biomodels of bone, and presents a review of model generation methodologies, giving examples of typical biomodel applications. The use of macroscale biomodels for such issues as the design and preclinical testing of surgical implants and preoperative planning is discussed. At the microscale, biomodels of trabecular bone are examined and the link with scaffolds for tissue engineering is established. Conclusions are drawn on the state of the art, and the major developments necessary for the continued expansion of the field are identified. Finally, arguments are given on the benefits of integrating the use of the different types of biomodels reviewed in this paper, for the benefit of future research in biomechanics and biomaterials.
