Article Abstract
Background: Biocompatible computer-assisted design (CAD) implants for cranioplasty are associated with high costs and considerable waiting time. We present the results of the first cranioplasty experience in our country using polymethylmethacrylate (PMMA) with customized 3D molds of the cranial defect.
Methods: We present a case series describing five patients with extensive cranial defects who underwent cranioplasty with PMMA using customized 3D molds. From tomographic studies, a bone implant model for the cranial defect was virtually designed and a mold was built according to the specifications of the defect. The mold was printed in 3D using acrylonitrile-butadiene-styrene. With the sterile mold, the implant could be designed intraoperatively with PMMA to perform the cranioplasty. The evolution, complications, and cost of the implant were evaluated.
Results: No postoperative complications were observed. Good aesthetic and functional results were achieved in all patients. The cost of the implant per patient using our technique was approximately $350 USD. In our country, the cost of CAD implants varies between $10000 and $20000 USD.
Conclusions: Cranioplasty with PMMA and 3D custom mold is a safe and low-cost technique that would benefit patients in middle- and low-income countries. Compared to CAD implants, the cost was reduced by 95%-97%. This technique can be implemented on a large scale with remarkable benefits in low- and middle-income countries.

Two Million Cycle Fatigue Performance of Custom and Stock Conical-Hex Abutments: A Removal Torque and SEM Study.

Introduction: Screw loosening remains a frequent mechanical complication in implant-supported prostheses, primarily caused by the gradual loss of abutment-screw preload. The aim of this study was to evaluate the mechanical performance of CAD-CAM custom and stock abutments by measuring removal torque values (RTV) at multiple time points and assessing surface morphology by scanning electron microscopy (SEM), following prolonged loading up to 2 × 10 cycles.
Methods: Forty-four implant-abutment assemblies with an internal conical-hex connection were divided into two groups: Stock abutments (SA) and custom abutments (CA).

Purpose: The kinematic alignment (KA) technique aims to restore native joint anatomy; however, the extent to which it restores posterior femoral condylar morphology after total knee arthroplasty (TKA) remains unclear. The posterior longitudinal overhang in the femoral condyle (PLOF) has been reported to affect clinical outcomes. This study aimed to compare the PLOF after medial pivot TKA performed using KA and mechanical alignment (MA) techniques.

Statement Of Problem: Immediate implant and interim restoration placement in the maxillary anterior esthetic zone presents challenges in achieving optimal implant positioning, esthetics, and peri-implant tissue stability. A more accurate and efficient clinical workflow is needed to address these demands.
Purpose: This study aimed to establish a fully digital workflow that combines autonomous robotic-assisted immediate implant placement and prefabricated interim restorations in the maxillary anterior esthetic region and to evaluate its accuracy and short-term clinical outcomes.

Craniofacial rehabilitation demands a multidisciplinary approach where prosthodontists play a pivotal yet often underutilized role in the continuum of care. Traditionally, prosthetic rehabilitation is considered a postsurgical step, leading to delays in functional restoration and compromised outcomes. This editorial emphasizes the need to redefine prosthodontics as an integral component of craniofacial surgical planning, from the operating room to the dental chair.

Background: Super-resolution deep learning reconstruction (SR-DLR) algorithm has emerged as a promising image reconstruction technique for improving the image quality of coronary computed tomography angiography (CCTA) and ensuring accurate CCTA-derived fractional flow reserve (CT-FFR) assessments even in problematic scenarios (e.g., the presence of heavily calcified plaque and stent implantation).
