The value of computer-aided implant planning using cone-beam computerized tomography (CBCT) for single immediate implants was explored. Eighteen patients requiring extraction of a tooth followed by a single immediate implant were enrolled. Small volume preoperative CBCT scans were used to plan the position of the implant. A taper screwed-type implant was immediately placed into a fresh socket using only the final 1 or 2 drills for osteotomy. Postoperative CBCTs were used for the analysis of actual implant placement positioning. Measurements of the planned and the actual implant position were made with respect to their position relative to the adjacent teeth. Mesio-distal displacements and the facial-lingual deviation of the implant from the planned position were determined. Changes in the angulation of the planned and actual implant position in relation to the clinical crown were also measured. To statistically summarize the results, box plots and 95% CIs for means of paired differences were used. The analysis showed no statistical difference between the planned position and final implant placement position in any measurement. The CBCT scans coupled with the computer-aided implant planning program along with a final 1-to-2 drill protocol may improve the accuracy of single immediate implant placement for taper screwed-type implants.

Background And Objectives: A typical workflow for deep brain stimulation (DBS) surgery consists of head frame placement, followed by stereotactic computed tomography (CT) or MRI before surgical implantation of the hardware. At some institutions, this workflow is prolonged when the imaging scanner is located far away from the operating room, thereby increasing workflow times by the addition of transport times. Recently, the intraoperative O-arm has been shown to provide accurate image fusion with preoperative CT or MR imaging, suggesting the possibility of obtaining an intraoperative localization scan and postoperative confirmation.

The Berlin Heart EXCOR is a pulsatile paracorporeal ventricular assist device (VAD) for neonates, infants, children and adults with congenital or acquired severe ventricular dysfunction. Berlin Heart EXCOR VADs are routinely used as either a bridge to a cardiac transplantation, or occasionally as a bridge to ventricular recovery. Our programmatic philosophy is to bridge neonates and infants with functionally univentricular ductal-dependent systemic circulation or functionally univentricular ductal-dependent pulmonary circulation who are at high risk for staged palliation because of important cardiac risk factors with a single-ventricle VAD (sVAD) as a bridge to a cardiac transplant.

Leptin increases focal inflammation and osteolysis induced by polyethylene particles in leptin-deficient ob/ob mice suggesting the adipokine, an important immune modulator, contributes to orthopedic implant failure. Focal inflammation leads to bone loss at distant skeletal sites, and it is plausible that leptin also contributes to this response. We tested this possibility in 6-week-old female ob/ob mice (6-8/group) by evaluating bone architecture, turnover, and gene expression 12 days following surgical placement of polyethylene particles over calvaria.

Background: Mastopexy combined with implant placement is a complex cosmetic surgery due to the dual nature of the procedure. Various mammoplasty techniques and implant types add to its intricacy. This study aimed to evaluate the effectiveness of an internal breast lift in correcting pseudoptosis, grade 1 breast ptosis, and asymmetries, thereby offering a safer alternative with reduced morbidity and avoiding the creation of an inverted T scar.

Many patients with neurofibromatosis type 2 (NF2) suffer from sensorineural hearing loss, and associated cochlear nerve compromise in NF2 patients makes auditory brainstem implant (ABI) an attractive treatment option. The long-term outcomes and benefits of the device are still being explored. A retrospective review was conducted for 11 ABI recipients at a single-institution tertiary center between November 2017 and August 2022.
