Objectives: To investigate the performance of a deep learning (DL) model for segmenting cone-beam computed tomography (CBCT) scans taken before and after mandibular horizontal guided bone regeneration (GBR) to evaluate hard tissue changes.
Materials And Methods: The proposed SegResNet-based DL model was trained on 70 CBCT scans. It was tested on 10 pairs of pre- and post-operative CBCT scans of patients who underwent mandibular horizontal GBR.
Is a greater degree of constraint really harmful? Clinical biomechanical comparative study between condylar constrained knee and rotating hinge prosthesis.
Clin Biomech (Bristol)

Article Synopsis
- The study compares the tibial rotation between two types of knee implants: rotating hinge knee prostheses and constrained condylar prostheses, focusing on clinical outcomes in revision knee arthroplasty.
- It included 20 patients, with 10 receiving each type of prosthesis, and tibial rotation was measured at various degrees of knee flexion using accelerometers.
- Results showed that the rotating hinge knee group had significantly higher tibial rotation and better postoperative Knee Injury and Osteoarthritis Outcome Scores, suggesting it may offer greater clinical satisfaction due to its lower rotational constraint.
This work analyzed the use of Microsoft HoloLens 2 in orthopedic oncological surgeries and compares it to its predecessor (Microsoft HoloLens 1). Specifically, we developed two equivalent applications, one for each device, and evaluated the augmented reality (AR) projection accuracy in an experimental scenario using phantoms based on two patients. We achieved automatic registration between virtual and real worlds using patient-specific surgical guides on each phantom.

- Image-guided surgery and advanced technologies like 3D printing are transforming head and neck cancer surgeries by enhancing reconstructive methods and improving patient outcomes.
- A study with 11 patients utilizing a new workflow showed that the accuracy of implant placement improved significantly using a combination of intraoperative navigation and 3D-printed guides, leading to a deviation of only 1-1.5 mm from the virtual plans.
- Despite initial challenges with accuracy in early cases, the integration of augmented reality and stable guides helped achieve successful, virtually planned dental prostheses for all patients.
