“…Intraoperative CBCT further reduces the risk of intraoperative extension of the surgical approach for a better view of the reduction and consequently reduces the risk of damaging surrounding anatomic structures. Pohlenz et al has hypothesized that intraoperative CBCT may enable good repositioning in condylar process despite the small operative access with a limited overview (Pohlenz et al, 2008). This has been proven in the present study.…”

“…The first studies were carried out on zygomaticomaxillary complex fractures (Heiland et al, 2004). We have previously demonstrated that the 3D C-arm delivered high-quality imaging with good information for the surgeon (Heiland et al, 2004;Pohlenz et al, 2008;Pohlenz et al, 2009). In this study we further demonstrate the usefulness of intraoperative CBCT for condylar process fractures, which have similar anatomical complexity to zygomaticomaxillary complex fractures.…”

“…However, the information it provides is limited by its two-dimensional (2D) nature, resulting in a lack of perspective, errors in projection and superimposition, imaging artifacts, variations in magnification, information voids, and head position errors (Liang et al, 2006;Pohlenz et al, 2008). Furthermore, the 2D images fail to represent the complex curving structures of the tooth-alveolar complex.…”

Abstract:Objective: To investigate the relationship between growth patterns and mandibular posterior tooth-alveolar bone complex morphology in a Chinese population with normal occlusion. Methods: Forty-five patients with normal occlusion (23 males, 22 females) were included in this study. Among these patients, 20 displayed the vertical growth pattern, and 20 had the horizontal growth pattern, while the remaining patients displayed the average growth pattern. All of the patients underwent dental cone beam computed tomography (CBCT), which included the region of the mandibular posterior teeth and the alveolar. A linear regression analysis and a correlation analysis between the facial height index (FHI) and the alveolar bone morphology were performed. Results: The inclination of the molars, the thickness of the cortical bone, and the height of the mandibular bone differed significantly between patients with the horizontal growth pattern and those with the vertical growth pattern (P<0.05). Significant positive correlations were found between: the FHI and the inclination of the molars; the FHI and the thickness of the cortical bone; and the FHI and the height of the mandibular bone. Conclusions: The mandibular posterior tooth-alveolar bone complex morphology may be affected by growth patterns.

“…This technique is particularly suitable for differentiating the bones from other tissues and thus has been often used in the image-guided surgery such as oral surgery [7], orthopedic surgery [8], neurosurgery [9] as well as the prostate brachytherapy [10] However, due to the cost and the radiation exposure associated with such techniques, they are not ideal for intraoperatively measuring the tissue deformation during a minimally invasive surgery.…”

Abstract-This paper presents a novel miniaturized force-indentation depth (FID) sensor designed to conduct indentation on soft tissue during minimally invasive surgery. It can intra-operatively aid the surgeon to rapidly identify the tissue abnormalities within the tissue. The FID sensor can measure the indentation depth of a semi-spherical indenter and the tissue reaction force simultaneously. It make use of with fiber optical fiber sensing method measure indentation depth and force and is small enough to fit through a standard trocar port with a diameter of 11 mm.The created FID sensor was calibrated and tested on silicone block simulating soft tissue. The results show that the sensor can measure the indentation depth accurately and also the orientation of the sensor with respect to the tissue surface whilst performing indentation. . I. INTRODUCTIONThere ). Distinct advantages of these robotic systems include high distal dexterity, enhanced 3D vision, motion scaling and tremor filtering as well as direct hand-eye coordination eliminating reversed tool motions. These advances result in improved ergonomics and also allow complex surgical procedures, which are usually difficult to be conducted by conventional minimally invasive means such as coronary artery bypass grafting [3] and mitral valve repair[4] to be effectively performed. However, the lack of haptic feedback in current robot-aided minimally invasive surgery systems is still one of the major downsides of such systems.Manuscript
