Computer-assisted Surgery system (CAS) is an effective medical imaging simulation tool, which is widely used in preoperative planning of surgery. The objective of this study is to investigate the clin...
This retrospective study investigated 74 children who underwent mediastinal tumor resection between June 2008 and June 2022 at the pediatric surgical center of the Affiliated Hospital of Qingdao Unive...
The median operative duration was 119.00 min in the CAS-assisted group and 140.50 min in the control group. The median intraoperative blood loss of the CAS-assisted group and the control group was 14....
Hisense CAS could effectively assist surgeons to clearly determine the anatomical site of tumors and provide accurate preoperative simulation for surgeons, so as to assist surgeons to specify effectiv...
Using computer-assisted surgery (CAS) and patient-specific plates (PSP) in orthognathic surgery has shown improved accuracy and efficiency compared with traditional techniques. This study analyzed cur...
A survey of 29 multiple choice questions was distributed to AO Foundation Craniomaxillofacial e-mail subscribers biweekly between July 14, 2021 and September 2, 2021. Questions focused on specifics of...
Of the 557 responses, 420 (75.4%) participant responses were eligible for analyses. Most (302/420, 71.9%) respondents used CAS when performing orthognathic surgery, although regional differences were ...
Our study shows differences in use regionally and with surgeon experience. Surgeons primarily use CAS and PSP in orthognathic surgery to increase accuracy and efficiency, minimize intraoperative devia...
Computer-assisted procedures are becoming increasingly more relevant in orthopedics and trauma surgery. The data situation on these systems has improved in recent years but still has a low level of ev...
Technological advancements in optoelectronic motion capture systems have allowed for the development of high-precision computer-assisted surgery (CAS) used in cranial and spinal surgical procedures. E...
Computer-assisted high tibial osteotomy (HTO) is a frequently used treatment technique for lower extremity orthopedics, and its small incision and low exposure area are major limitations in tibial reg...
After the initialization stage, the bone surface and skin surface data are combined to construct registration features. Then, a steepest perturbation search method is performed after the ICP algorithm...
Phantom experiments including simulated human tissue show that the proximal fiducial registration error (FRE) of our method can reach 0.80 ± 0.30 mm (mean ± SD) with an overall rotational error < 1° a...
The approach fully describes a well-defined framework without additional imaging acquisition equipment for Computer-assisted HTO. By the experiment on the basis of a phantom with simulated soft tissue...
This technique report describes an alternative method to stabilize surgical templates throughout full-arch static computer-assisted implant surgery (FA s-CAIS). In FA s-CAIS, remaining teeth, mucosa, ...
To assess the accuracy and patient reported outcome measures (PROMs) of the computer-guided "double factor" technique for treating fully edentulous patients....
A proof of concept prospective study was designed. Ten consecutive patients requiring full arch dental implant supported rehabilitation in a private practice were enrolled between October 2021 and Mar...
A total of 48 implants were placed using the "double factor" technique, and 12 full-arch immediate loading prostheses were delivered. The mean angular deviation was 3.74° (standard deviation [SD]: 2)....
The "double factor" technique is a valid and accurate treatment approach for fully edentulous patients....
The double factor technique merges the advantages of both the dynamic and static computer assisted surgery approaches, affording accurate and predictable results when treating fully edentulous patient...
To evaluate the accuracy of implant placement using a dynamic navigation system in fully edentulous jaws and to analyze the influence of implant distribution on implant position accuracy....
Edentulous patients who received implant placement using a dynamic navigation system were included. Four to six mini screws were placed in the edentulous jaw under local anesthesia as fiducial markers...
A total of 13 edentulous patients with 13 edentulous maxillae and 7 edentulous mandibles were included, and 108 implants were placed. The average linear deviations at the implant entry point and apex ...
The dynamic navigation system provides high accuracy for implant placement in fully edentulous jaws, while the distribution of the implants showed little impact on implant position accuracy....
Osteoid osteoma is a benign osteogenic tumor that occurs mostly in the femoral stem, while osteoid osteoma occurring in the lumbar vertebral body is a relatively rare case. To minimize treatment-relat...
We report a 19-year-old adult male with low back pain that worsened at night and CT, MRI imaging showed an abnormal signal shadow at the posterior margin of the lumbar vertebral body. Due to the proxi...
In this case, we report an osteoid osteoma that occurs less frequently in the lumbar vertebral body. Using computer-assisted navigation with fully visualized spinal endoscopy, we successfully resected...
Dynamic Computer Assisted Implant Surgery (CAIS) systems have been shown to improve accuracy of implant placement, thus training in the use of such systems is becoming increasingly important. There is...
To determine the effectiveness of two modes of CAIS training programs on motor skill acquisition of novice surgeons....
Thirty-six postgraduate students without experience in dynamic CAIS systems were randomly assigned to a distributed training program (3 training sessions over 3 days) or a massed training (3 training ...
Both groups reached the accuracy benchmarks expected by current standards in the use of CAIS. No significant differences with regards to accuracy were found between the groups, but a trend was documen...
Novice students reached the accuracy benchmarks with the use of CAIS through both a massed and a distributed training program, while there was a strong but marginally not significant trend for higher ...
