The optimal position of the implant in 3 dimensions in space is the most important factor to ensure the long - term success of dental implants. Through 3D printing technology, it is possible to transfer the virtual implant position to the surgical field using a static surgical guide. This study aims to evaluate the accuracy of 3D printed surgical guides when performing implant when performed using 3D printed surgical guides.

Hydrogels loaded with chemotherapeutics are promising tools for local tumor treatment. In this work, redoxresponsive implantable hydrogels based on gellan gum were prepared as paclitaxel carriers for HER2-positive breast cancer therapy. To achieve different degrees of chemical crosslinking, hydrogels were synthesized in both acetate buffer and phosphate buffer and crosslinked with different concentrations of L-cysteine.

The importance of the tip-apex distance (TAD) to predict the cut-out risk of fixed angle hip implants has been widely discussed in the scientific literature. Intra-operative determination of TAD is difficult and can be hampered by image quality, body habitus, and image projection.

There are few Scandinavian studies on the effect of computer assisted orthopedic surgery (CAOS) in total knee arthroplasty (TKA), compared to conventional technique (CON), and there is little information on effects in pain and function scores.

Despite good results of primary total knee arthroplasty (TKA), the number of revision total knee arthroplasties (rTKAs) is rising. Proper implant position is essential, since malposition leads to worse clinical outcome.

The evaluation of postoperative total knee arthroplasty (TKA) alignment mainly relies on measurement data obtained from plain radiographs. The aim of this retrospective observational study was to document the intra- and inter-observer reliability in assessment of TKA component positioning after surgery using a three-dimensional (3D) computed tomography (CT) image matching system.

Minimal invasive surgery (MIS) has gained growing popularity in total hip arthroplasty (THA) but concerns exist regarding component malpositioning. The aim of the present study was to evaluate femoral and acetabular component positioning in primary cementless THA comparing a lateral to a MIS anterolateral approach.

In total hip arthroplasty (THA), tilting of the pelvis alters the cup placement angles. Thus, the cup angles need to be planned with consideration of the effects of pelvic tilt. In the present study, we evaluated the efficacy of preoperative planning for implant placement with consideration of pelvic tilt in THA, and the accuracy of a CT-based computer navigation for implant positioning.

Little is known about the strains at the glenoid near the bone-implant interface in reverse shoulder arthroplasty. The purpose of the current study was to evaluate the strains on the glenoid bone under a compressive load after implantation of three different sizes of metal-backed baseplates in either inferior or superior position in combination with three different sizes of glenospheres and three different glenosphere designs.

Due to the high anatomical variability and limited visualization of the scapula, optimal screw placement for baseplate anchorage in reversed total shoulder arthroplasty (rTSA) is challenging. Image quality plays a key role regarding the decision of an appropriate implant position. However, these data a currently missing for rTSA and were investigated in the present study.

Computer Assisted Surgery (CAS) has proven to improve the accuracy in several orthopedic procedures. Therefore we used this technique to evaluate femoral component positioning in Hip Resurfacing Arthroplasty (HRA). The aim of this study was to evaluate imageless CAS compared to manually implanted femoral components and subsequently evaluates Patient Related Outcome Measures (PROMs).

Modern metal-on-metal (MOM) arthroplasties were performed for over a decade before alarming reports of adverse metal reactions dramatically reduced their use. Failures are seen more often with high-wearing implants, but also well-positioned components with more favourable wear patterns can cause problems.

Endophthalmitis is an event which is considered to be quite rare nowadays. There are many studies on post cataract endophthalmitis but very few studies have come up on post cataract Bacillus endophthalmitis and our study focuses on a similar event. Our aim was to evaluate an outbreak of post operative endophthalmitis which took place in a hospital in north Kashmir and lasted over a period of three weeks. Elective cataract surgery was performed on patients, all above 50 years of age with intra ocular lens implantation.

Our memory access mechanism provides hardware sup- port for unprivileged malicious software by allowing ac- cess to privileged memory regions. Malicious software triggers the attack by forcing a sequence of bytes on the data bus to enable the memory access circuits. This se- quence can be arbitrarily long to avoid false positives and the particular sequence must be agreed upon be- fore deployment.

The specic robotic system considered is a vehicle whose kinematic model approximates the mobility of a car. The conguration of this robot is repre- sented by the position and orientation of its main body in the plane, and by the angle of the steering wheels. Two velocity inputs are available for motion control. This situation covers in a realistic way many of the existing robotic vehicles. Moreover, the car-like robot is the simplest nonholonomic vehicle that displays the general characteristics and the dicult maneuverability of higher- dimensional systems, e.g.

All this information was important for the determination of the villous height /crypt depth ratio that may indicate the proper development of intestinal epithelia regulated by probiotics. Authors also deliberate on the villous surface area parameter that may contribute to the enhancement of the intestinal absorptive area which seems to be positively regulated by probiotics in a majority of the available evidence.

Timing of Cardiac Surgery In general, when indications for surgical treatment of infective endocarditis are identified, surgery should not be delayed simply to permit additional antibiotic therapy, since this course of action increases the risk of death (Table 118-6). Delay is justified only when infection is controlled and congestive heart failure is fully compensated with medical therapy. After 14 days of recommended antibiotic therapy, excised valves are culture-negative in 99% and 50% of patients with streptococcal and S. aureus endocarditis, respectively.
