Thoracic endovascular aortic repair (TEVAR) is an established treatment option, though some anatomical challenges require a through-and-through wire technique, and subsequently transapical access via minithoracotomy can be required. It is clear that an objective tool to facilitate decision-making is needed. A 3D print of a severely angulated aortic arch was used as a template to advance a stent-graft and this was achieved after pulling the top of the wire. This simulation assisted in decision-making relating to transapical access with a wire externalization...

A pediatric mandibular fracture can cause a child severe pain and the parent or caregiver extreme worry. While the pattern of fractures in children is similar to adults, however, due to a number of factors, including the anatomical complexity of the developing mandible, management of such fractures differs from that of adults and can greatly challenge the pediatric dentist. Various treatment modalities of managing mandibular fracture are available, such as closed/open cap splint with circummandibular wiring, arch-bar fixation, and cementation of the cap splint...

Circumpalatal wiring has 2 negative points. The first is premature loosening of the wire and the second is tongue irritation caused by exposed wire in roof of the mouth. In this article, a modified technique (palatal wiring) is introduced in which these 2 problems are targeted. In this technique, a small bur hole is created into the hard palate, without the need for flap reflection and wire is passed through it, grasps in the nose, and returns to the oral cavity via sublabial puncture point then 2 ends are twisted in labial vestibule...

This case report demonstrates the treatment of a skeletal Class II high-angle adult patient with bimaxillary protrusion, angle Class I occlusion, and crowded anterior teeth. A ribbon-wise arch wire and a customized lingual appliance with anterior vertical slots were used to achieve proper torque control of the maxillary anterior teeth. An orthodontic anchor screw and a palatal bar were used for vertical control to avoid increasing the Frankfort-mandibular plane angle (FMA) by maxillary molar extrusion. Through the combined use of the ribbon-wise customized lingual appliance, palatal bar, and orthodontic anchor screw, vertical control and an excellent treatment result were achieved without the vertical and horizontal bowing effects peculiar to conventional lingual treatment...

INTRODUCTION: The main causes of failures in canine traction are anchorage defects, incorrect direction of force, uncontrolled forces. An adolescent female (10 years, 9 months) presents with two included canines on the maxillary arch, in a palatal position and her lateral incisors (12 and 22) are microdontic. Two mini-screws are inserted on the palate, in a mesial position to 16 and 26 to secure the traction of 13 and 23; in general, braces are bonded after this first step. After debonding, mini-screws remain to help stabilize the palatal plate during the retention period and to avoid unaesthetic metallic wires and hooks which sometimes cause occlusal interferences...

Space gaining is frequently required in orthodontics. Multiple loops were initially used for space gaining and alignment. The most common used mechanics for space gaining is the use of nickel-titanium open coil springs. The disadvantage of nickel-titanium coil spring is that they cannot be used until the arches are well aligned to receive the stiffer stainless steel wires. Therefore, a new method of gaining space during initial alignment and leveling has been developed and named as sleeve push technique (SPT)...

Thromboembolism occurs commonly in general practice and leads to significant health burden. Apart from cardiac sources, aortic atherosclerotic plaques contribute considerably to thromboembolism. A 63-year-old diabetic hypertensive woman referred to our center due to exertional chest pain unresponsive to optimal medical therapy and underwent coronary angiography. Owing to resistance during guide-wire advancement, an aortography was performed. Aortic arch injection demonstrated a large suspended mass distal to the left subclavian artery with free movement in the descending thoracic aorta...
