Purpose is to emphasize the danger and necessity for the treatment of clinical complications from dental trauma without appropriate reimplantation and applied space maintainer. Two clinical cases with dental trauma without appropriate reimplatation and used space maintainer resulting in complications of the dental arch were treated with different orthodontic techniques. The first clinical case ...

To present an uncommon disturbance of root development with ingrowth of bone and periodontal tissue into the pulp space in a delayed replanted immature permanent incisor at five years of follow-up. Severe arrest of root formation with uncommon healing of an immature permanent maxillary incisor after delayed replantation is reported. Continued development of a tooth root separate from the body o...

PURPOSE The purpose of this animal study was to perform a histological and histomorphometric analysis in order to elucidate the effect of fibroblast growth factor-2 (FGF-2) on injured periodontal ligament (PDL) and cementum after tooth replantation in dogs. METHODS The roots of 36 mandibular premolars from six mongrel dogs were used in this study. The roots were randomly divided into three gr...

The corresponding video is an aortic valve (AV) reimplantation using the Kuban Cuff modification technique (Video 1). The patient is a 36-year-old male with acute (3 days) DeBakey type I aortic dissection. He has Marfan syndrome, aortic root aneurysm of 65 mm, tricuspid aortic valve with aortic grade 3 insufficiency. The patient had a previous abdominal aortic replacement without any other sign...

Valve-sparing aortic root replacement (David reimplantation) has been recently used for treating annulo-aortic ectasia (AAE), and is associated with excellent survival and a low risk of late aortic valve replacement (AVR). However, the associated long-term durability of the repair remains uncertain because of the complexity of the aortic root and valve function. Previous studies have reported t...

O UT OF THE SEVERAL REPORTED EXperiments of lung reimplantation, a few basic concepts have been derived. A number of dogs have survived for long periods of time after reimplantation of one lung; however, the animals do not live for more than a few weeks after complete one stage removal of the contralateral normal lung.”#{176} The ventilatory function and oxygen consumption value of the transpla...

BACKGROUND The misplacement of electrodes is a possible explanation for suboptimal response to bilateral subthalamic nucleus (STN) stimulation in patients with Parkinson disease. OBJECTIVE To evaluate whether reimplantation of electrodes in the STN can produce improvement in patients with poor results from surgery and with suspected electrode misplacement based on imaging findings. DESIGN P...
