AI Article Synopsis

  • * Six design variables were studied simultaneously to assess their impact on stress distribution, with the Young's modulus of cancellous bone having the most influence, followed by implant thickness and placement angles.
  • * A one-dimensional CAE solver was developed to create a digital twin for dentists, allowing real-time evaluation of implant placement plans by integrating tooth image data for more objective decision-making.

Article Abstract

Real-time stress distribution data for implants and cortical bones can aid in determining appropriate implant placement plans and improving the post-placement success rate. This study aims to achieve these goals via a parametric reduced-order model (ROM) method based on stress distribution data obtained using finite element analysis. For the first time, the finite element analysis cases for six design variables related to implant placement were determined simultaneously via the design of experiments and a sensitivity analysis. The differences between the minimum and maximum stresses obtained for the six design variables confirm that the order of their influence is: Young's modulus of the cancellous bone > implant thickness > front-rear angle > left-right angle > implant length. Subsequently, a one-dimensional (1-D) CAE solver was created using the ROM with the highest coefficient of determination and prognosis accuracy. The proposed 1-D CAE solver was loaded into the Ondemand3D program and used to implement a digital twin that can aid with dentists' decision making by combining various tooth image data to evaluate and visualize the adequacy of the placement plan in real time. Because the proposed ROM method does not rely entirely on the doctor's judgment, it ensures objectivity.

Background: The number of people undergoing maintenance hemodialysis is increasing rapidly worldwide. Central vein stenosis (CVS) is a common vascular complication in undergoing hemodialysis, especially those with a history of catheterization. This study aimed to investigate the characteristics of CVS and the clinical effectiveness of percutaneous transluminal angioplasty (PTA) alone and sequential percutaneous transluminal stenting (PTS) in hemodialysis patients with CVS.

Objectives: To analyze the trends in the context of implant therapy in a 3-year patient population and compare it with data obtained over the last 20 years.

Materials And Methods: All adult subjects who received treatment in the context of implant therapy between 2020 and 2022 were included in this retrospective study. Data regarding patient demographics, indications and location of implant therapy, implant characteristics, surgical techniques, complications, and early implant failures were recorded and compared to data obtained in the years 2002-2004, 2008-2010, and 2014-2016.

Guided Bone Regeneration in the Posterior Mandible Using a Resorbable Metal Magnesium Membrane and Fixation Screws: A Case Report.

Case Rep Dent

Due to bone loss, implant placement in the posterior mandible is often impossible without prior augentative procedures. The reconstruction of bone defects with horizontal and vertical components using particulated bone grafts requires the placement of a mechanically stable structure for stabilization of the grafting material. Although titanium-reinforced membranes and titanium meshes have been shown to be effective in this indication, the necessity of their removal, often in a separate surgical procedure, is seen as a disadvantage.

Background: The coronary sinus reducer (CSR) is a therapeutic option for patients with coronary artery disease who are not eligible for further revascularization and experience refractory angina. Cardiac resynchronization therapy (CRT) improves symptoms and prognosis in heart failure with reduced ejection fraction, but the presence of a CSR may complicate left ventricular lead placement. Only four cases have been reported so far in this context.

Coronary artery anomalies (CAAs) are rare and challenging, with increased diagnoses due to advanced cardiovascular imaging, even in low-income countries where diagnostic and therapeutic approaches can be difficult. This case report details a 65-year-old Black male patient with a history of hypertension and smoking who presented with a myocardial infarction. Despite no significant abnormalities apart from the infarction, invasive coronary angiography revealed a dominant right coronary artery (RCA) and an anomalous left main coronary artery (LMCA) originating from the right coronary sinus, bifurcating into the left anterior descending artery and circumflex artery.
