“…The paper forms a contribution to the increasing role of the computational intelligence and visualization tools in surgery. The direct consequence of the very fast technological progress is the more extensive use of the three-dimensional treatment planning with 3D reconstruction, especially in connection with 3D printing and experimental robotic-assisted surgery [40], [41].…”

Anthropometric studies focusing on facial metrics and their proportions form an important research area devoted to observations of the appearance of the human skull. Many different applications include the use of craniometry for maxillofacial reconstruction and surgery. This paper explores the possibility of using selected craniometric points and associated metric to observe spatial changes during the maxillofacial surgery treatment. The experimental dataset includes observations of 27 individuals. The proposed method is associated with the processing of measurements by selected methods of signal processing and computational intelligence. The statistical results point to changes of facial measures before and after the maxillofacial surgery. The proposed method conclusively demonstrates that the area of the mean upper law triangle after surgical treatment is decreased by 8.5%, at the 5% significance level of the two-sample t-test. The classification of selected measurements by a neural network model reached an accuracy of 84.9%.

“…Traditional oral surgery relies entirely on the manual operation of the surgeon, so the accuracy, safety, and prognosis quality cannot be well guaranteed. The development of robotics provides new ways for oral surgery, which has great potential to assist surgeons to provide highquality surgery and become the mainstream solution in the future [8][9][10].…”

In robot-assisted oral surgery, the surgical tool needs to be fed into the target position to perform surgery. However, unmodeled extraoral and complex intraoral environments bring difficulties to motion planning. Meanwhile, the motion is operated manually by the surgeon, causing relatively limited accuracy as well as the risk of misoperation. Moreover, the random movements of the patient’s head bring additional disturbance to the task. To achieve the task, a motion strategy based on a new conical virtual fixture (VF) was proposed. First, by preoperatively specifying a conical guiding cone as the VF, virtual repulsive forces were applied on the out-of-range end effector. Then, based on the two-point adjustment model and velocity conversion, the effect of VF was established to prevent the end-effector from exceeding the constraint region. Finally, a vision system corrects the guiding cone to compensate for the random movement of the patient’s head to feed to a dynamic target. As an auxiliary framework for surgical operation, the proposed strategy has the advantages of safety, accuracy, and dynamic adaptability. Both simulations and experiments are conducted, verifying the feasibility of the proposed strategy.

“…Dental implant surgery, by placing an implant into the hole on the jaw bone, can restore almost all the function of teeth, 3,4 and is the most powerful therapy. Currently, dental implant surgery still mainly relies on the skill of doctors and computed tomography (CT) images, 5 with some problems existing. Firstly, due to the narrow workspace, not only is the view field limited, 6 but also the operation is not comfortable, and it is easy to get tired.…”

BackgroundThis study aims to develop a new dental implant robotic system (DIRS) to relieve the burden and enhance the quality of dental implant surgery.MethodsThe implanting actuator and system controller are two parts. The implanting actuator is designed on the basis of the RCM mechanism, with its kinematics modelled. Besides, a multi‐DOF admittance control strategy and a hybrid position‐admittance control strategy were designed, endowing the actuator with environmental compliance.ResultsIn force sensing, about 97% of mixed force/torque are eliminated. Then, 30 groups of implantation are done, of which 15 groups are simple implantation, while another 15 groups are force‐based implantation. The results show that the average contact force/torque can be reduced by 73.03% and 62.66%, and the peak contact force/torque can be reduced by 68.26% and 50.46%.ConclusionsThe results of preliminary experiments validate the effectiveness of DIRS, which has great potential to assist dentists with higher efficiency, better quality, and lower burden.
