PURPOSE Clinical success of implant prosthodontics is dependent in part upon the type of implant thread design. The selection of implant thread design plays an important role in the outcome of the treatment. This study was undertaken to evaluate the pattern of stress distribution using a finite element analysis; hence, the area which would be bearing maximum load for a given design would be arr...

Introduction: Adequate reconstruction of the skull base is the key to avoiding cerebrospinal fluid (CSF) leak following endonasal skull base surgery. The use of an endocranial “gasket” plug has been reported for this and is used in our institution. We present a simple refinement of the “gasket” technique using commonly available materials that helps ensure proper size and positioning of the gas...

Introduction Intertrochanteric (IT) fractures are most common fractures seen in elderly osteoporotic, usually due to simple fall in the house. With increasing number of elderly patients its number is estimated to be double by 2040 [1]. Understanding important factors in management of IT fracture like stability, reduction, role of posteriomedial wall, lateral wall, will help in choosing implant ...

Many animal species use vocal and nonvocal acoustic signals to communicate over large distances. Wild chimpanzees, Pan troglodytes, drum on the buttress roots of trees, generating low-frequency sounds that can reach distances 1 km. Buttress drumming is produced in bouts beats often accompanied by pant hoots, species-typical long-distance vocalization. We investigated whether individual differen...

Colony counting by spreading bacterial suspensions on plating media by various techniques is of general concern. Comparative studies between hand plating (Drigalski-spatula technique) for different time intervals and spiral plating resulted in significant differences in colony counts. Lower counts of Gram-negative bacteria were obtained by using hand plating for more than 10s, compared with sho...

BACKGROUND Posterior fusion of the spine to the pelvis in paediatric and adult spinal deformity is still challenging. Especially assembling of the posterior rod construct to the iliac screw is considered technically difficult. A variety of spinopelvic fixation techniques have been developed. However, extreme bending of the longitudinal rods or the use of 90-degree lateral offset connectors prov...

The purpose of this study was to determine the optimal thread shape for an experimental cylinder implant. Twelve three-dimensional finite element models with an implant of different thread shape were created: 1mm, 2mm, and 3mm square designs (S-1, S-2, and S-3); 90, 60, and 30 V-shaped designs (V-1, V-2, and V-3); 45, 30, and 15 buttress designs (B-1, B-2, and B-3); 45, 30, and 15 reverse buttr...
