NCT ID: NCT06001515 Recruiting - Clinical trials for Computer-Assisted Surgery

Effect of Face Scanning on Accuracy of Dental Implant Placement in Fixed Implant Supported Maxillary Prostheses

Start date: November 1, 2023
Phase: N/A
Study type: Interventional

The study will compare the accuracy of surgical guides fabricated by two different scanning protocols; facially driven scanning versus dual scanning protocol regarding the deviation of implant placement.

NCT ID: NCT05656053 Active, not recruiting - Glioma, Malignant Clinical Trials

Intraoperative Rapid Diagnosis of Glioma Based on Fusion of Magnetic Resonance and Ultrasound Imaging

Start date: November 15, 2021
Phase:
Study type: Observational [Patient Registry]

The aim of this observational study is to enable rapid diagnosis of molecular biomarkers in patients during surgery by medical imaging and artificial intelligence models, to help clinicians with strategies to maximize safe resection of gliomas. The main questions it aims to answer are: 1. To solve the current clinical shortcomings of intraoperative molecular diagnosis, which is time-consuming and complex, and enables rapid and automated molecular diagnosis of glioma, thus providing the possibility of personalized tumor resection plans. 2. To implement a neuro-navigation platform that combines preoperative magnetic resonance images, intraoperative ultrasound signals and intraoperative ultrasound images to address real-time molecular boundary visualisation and molecular diagnosis for glioma, providing an approach to improve glioma treatment. Participants will read an informed consent agreement before surgery and voluntarily decide whether or not to join the experimental group. they will undergo preoperative magnetic resonance imaging, intraoperative ultrasound, and postoperative genotype identification. Their imaging data, genotype data, clinical history data, and pathology data will be used for the experimental study. The data collection process will not interrupt the normal surgical process.

NCT ID: NCT05221554 Recruiting - Clinical trials for Total Hip Arthroplasty

Pre-Op THA Modelling

Start date: August 1, 2022
Phase: N/A
Study type: Interventional

Replacing diseased hip joints with prosthetic implants in a procedure called total hip arthroplasty (THA) is associated with high rates of patient satisfaction, pain relief, and functional improvement when the implant is appropriately placed. Incorrect implant size or placement may lead to a breadth of negative outcomes, which could result in the need for implant revision. It is difficult to assess the precise orientation of patient hips on the operating table, with one study revealing that only 26% of acetabular cups placed without technological assistance are correctly positioned. Using computer navigation as a guide to achieve optimal implant alignment may improve successful placement rates. The additional incorporation of real-time modeling software may further help realize higher rates of successful implant placement. This study, therefore, aims to investigate a computer navigation system coupled with real-time modeling software to establish the benefit of such technology in the operating room, and further improve positive patient outcomes following THA. We hypothesize that including technological assistance in THAs will yield better patient outcomes compared to surgeries performed freehand.

NCT ID: NCT04950491 Completed - Quality of Life Clinical Trials

Patient-reported Outcome Measures Comparing Static Computer-aided Implant Surgery and Conventional Implant Surgery

Start date: July 9, 2019
Phase: N/A
Study type: Interventional

The aim of this randomized controlled trial was to compare PROMs in patients receiving single tooth replacement in posterior sites by s-CAIS and CIS.

NCT ID: NCT04895319 Completed - Clinical trials for Maxillofacial Abnormalities

Adherence to Computer-assisted Maxillofacial Reconstructions

Start date: January 1, 2014
Phase:
Study type: Observational

The study was approved by the Local Ethics Committee and was conducted in compliance with the World Medical Association Declaration of Helsinki on medical research. A total of 335 patients who underwent oral and maxillofacial reconstruction were recorded from Jan 2014 to Jun 2020. Reconstruction with computer-assisted surgery ( CAS), which included, virtual surgical planning, computer-aided design-computer-aided manufacturing (CAD-CAM) surgical guides/templates and pre-bent plates on 3D printed models. Reasons for tissue defect were oncologic, osteoradionecrosis, trauma and osteoporosis. Patients undergoing dental implant placement and orthognathic surgery were excluded. Finally, 136 patients were selected and the reasons for partial or abandon surgical plan performance were described and analyzed.

NCT ID: NCT03391089 Enrolling by invitation - Clinical trials for Computer-assisted Surgery

Non-contact Intraoperative Optical Imaging During Spinal Procedures

Start date: January 21, 2016
Phase: N/A
Study type: Interventional

Current spine procedures can suffer from a variety of complications resulting in a high incidence (up to 55%) of misplaced screws and implants. This can lead to devastating clinical consequences, including neurologic and vascular injury, and extensive physical, mental, and economic damage. Surgical navigation has a great potential to reduce these risks through accurate guidance; however present technologies rely on intraoperative imaging that uses ionizing radiation (e.g. computed tomography, or fluoroscopy), which limits surgical anatomy registration updates to less than 3-4 time points during surgery. They also require cumbersome and lengthy set-up and registration of fiducial markers and have limited abilities to account for motion that occurs during surgery and patient positioning. Therefore, the investigators propose a real-time intraoperative optical topographical imaging based surgical guidance system capable of accurately guiding the placement of implanted devices such as screws.

NCT ID: NCT03391024 Completed - Clinical trials for Computer-assisted Surgery

Non-Contact Intraoperative Optical Imaging During Instrumentation Procedure

Start date: September 24, 2013
Phase: N/A
Study type: Interventional

For a significant number of patients suffering from back pain, even basic daily activities become impossible. It is at this time that spinal surgery becomes necessary in order to improve the patient's quality of life. To combat these symptoms, surgical implants (e.g. pedicle screws, rods, etc.) are used to aid in stabilizing and correcting the deformities of the spine, particularly after spinal decompression. Surgical navigation has a great potential to improve the accuracy of correctly implanting these devices; however, present technologies rely on intraoperative imaging that uses ionizing radiation (e.g. computed tomography, fluoroscopy, etc.), require cumbersome set-ups, the physical attachment of fiducial markers, and cannot account for patient motion. Therefore, the investigators propose a real-time intraoperative optical topographical imaging based surgical guidance system capable of accurately guiding the placement of implanted devices such as pedicle screws.

NCT ID: NCT03391011 Enrolling by invitation - Clinical trials for Computer-assisted Surgery

Non-contact Intraoperative Optical Imaging During Neurosurgical Procedures

Start date: March 13, 2015
Phase: N/A
Study type: Interventional

For a significant number of patients suffering from back pain, even basic daily activities become impossible. It is at this time that spinal surgery becomes necessary in order to improve the patient's quality of life. To combat these symptoms, surgical implants (e.g. pedicle screws, rods, etc.) are used to aid in stabilizing and correcting the deformities of the spine, particularly after spinal decompression. The clinical need for spinal surgery is compounded by current and continuing demographic trends. As the general population continues to age, the number of orthopaedic surgical interventions is expected to rise drastically. Therefore, a significant opportunity exists for the implementation of surgical guidance technologies, for orthopaedic procedures, to combat this overwhelming health care burden.
