Prosthetically CAD-CAM-Guided Bone Augmentation of Atrophic Jaws Using Customized Titanium Mesh: Preliminary Results of an Open Prospective Study.

This study evaluated the outcomes of computer-aided design-computer-aided machining (CAD-CAM)-customized titanium mesh used for prosthetically guided bone augmentation related to the occlusion-driven implant position, to the vertical bone volume gain of the mandible and maxilla, and to complications, such as mesh exposure. Nine patients scheduled for bone augmentation of atrophic sites were treated with custom titanium mesh and particulate bone grafts with autologous bone and anorganic bovine bone in a 1:1 ratio prior to implant surgery. The bone volume needed to augment was virtually projected based on implant position, width, and length, and the mesh design was programmed for the necessary retaining screws.

Giant coronary artery aneurysm in association with systemic arterial ectasia. A case report.

Since the advent of coronary angiography, coronary artery aneurysm has been diagnosed with increased frequency. The etiology of coronary artery aneurysm is atherosclerosis in 50%, followed by other causes. In a 71-year-old man with previously documented abdominal aortic aneurysm of 6 cm diameter and ectasia of both left and right middle cerebral arteries, thoracic magnetic resonance imaging (MRI) demonstrated a large hollow para-cardiac mass (maximum diameter of 7 cm) lying in the anterior-lateral part of the atrio-ventricular sulcus.
