Skeletal and dental effects of tooth-borne versus hybrid devices for mandibular symphyseal distraction osteogenesis. Angle Orthod. 2013 Jun 20; Authors: Niculescu JA, King JW, Lindauer SJ Abstract Abstract Objective: To evaluate and compare, retrospectively, the skeletal and dental effects of mandibular symphyseal distraction osteogenesis (MSDO) achieved through the use of tooth-borne versus hybrid distractors. Materials and Methods: Pretreatment (T1), predistraction (T2), postdistraction (T3), and posttreatment (T4) orthodontic records were collected and analyzed for 47 patients (20 tooth-borne, 27 hybrid). At each time point, records included intraoral photographs, study models, postero-anterior cephalometric radiographs, and lateral cephalometric radiographs. Submental vertex radiographs were taken at T2, T3, and T4. Changes in a total of 18 measurements were analyzed to compare patients undergoing tooth-borne versus hybrid distraction. Results: The cumulative effects of orthodontics and MSDO produced similar gains in measured arch widths, with a decreased irregularity index in both groups (P> .05). However, there were differences in the timing during which the expansion was achieved. The hybrid distractor group gained space during the distraction phase of treatment. The tooth-borne group showed greater gains during pre- and postdistraction orthodontics. Comparisons of intercanine and interbone marker widths demonstrated a more parallel separation of bo...
Conclusions: Radial head arthroplasty with a monoblock UHMW-PE RHP is safe and effective at short-term follow-up for treating acute unreconstructable radial head fractures with satisfactory functional and radiographic outcomes. Level of Evidence: Level IV.
Conclusions: For one-level ACDF, the anchored cage with screws has some advantage compared to the stand-alone PEEK cage in avoiding dysphagia and restoring disc space height and cervical lordosis. We suggest the anchored spacer may be a good substitute for the stand-alone cage in one-level ACDF. Level of Evidence: Level II
ConclusionsGTR of intrabony defects in AgP with either standard or modified CM yielded similarly successful and maintainable clinical benefits for compromised teeth 4 years following the surgery. The use of MPM showed no additional benefit.Clinical relevanceThis study demonstrates that most of the positive outcomes of GTR in AgP may be preserved over 4 years. Periodontitis recurrence might influence long-term outcomes.
Ysio Max, model no. 10762470 - Product Usage: The Ysio Max is a radiographic system used in hospitals, clinics, and medical practices. Ysio Max enables radiographic and tomographic exposures f the whole body including: skull, chest, abdomen, and extremities and may be used on pediatric, adult and bariatric patients. It can also be used for intravenous, small interventions (like biopsy, punctures, etc.) and emergency (trauma, critical ill) applications. Exposures may be taken with the patient sitting, standing, or in the prone position. The Ysio max system is not meant for mammography.
ARTIS Pheno-Interventional Fluoroscopic X-Ray System Model Number: 10849000 - Product Usage:AXIOM Artis is a family of dedicated angiography systems developed for single and biplane diagnostic imaging and interventional procedures including, but not limited to, pediatric and obese patients. Procedures that can be performed with the AXIOM Artis family include cardiac angiography, neuro angiography, general angiography, rotational angiography, operating room angiography, multipurpose angiography and whole body radiographic/fluoroscopic procedures. Axiom Artis can also support the acquisition of position triggered imaging for...
ConclusionAlthough rare, osteoid osteoma may occur in the hallux. Even if the patient age, pain pattern, and radiographic findings do not exactly meet the classical definitions for osteoid osteoma, this tumor should always be included in the differential diagnosis list in patients presenting with foot pain.
Assess the efficacy of deep convolutional neural networks in segmentation of peripherally inserted central catheters (PICC) and the location of the catheter tip relative to the superior vena cava (SVC) and right atrium (RA).
Polydioxanone (PPDO) is a resorbable polymer that has been shown to be effective resorbable inferior vena cava filters (IVCF) in preventing pulmonary embolism (PE). However, PPDO is radiolucent with no intrinsic capability for radiographic visualization. Here, we synthesized bismuth nanoparticles (BiNPs) and infused unto PPDO, making it visible by x-ray and computed tomography (CT). This enhanced radiopacity will allow placement accuracy during device implantation and continuous monitoring of the structural integrity of the device to check for fracture or device failure post implantation.
