Microimplants have changed the face of orthodontic clinical practice. One most important factors in a practice is reduced chairside time for patient as well clinician. This article presents short tip accurate placement microimplant.

Finite element analysis (FEA) has been proven as a useful design tool to model corrugated paperboard boxes, and is capable of accurately predicting load capacity. The in-plane deformation, however, usually significantly underpredicted. To investigate this discrepancy, panel compression test jig, that implemented simply supported boundary conditions, was built individual panels. panels were then...

Abstract Introduction Organoid models serve as a robust platform for investigating injury and disease in vitro. Currently, representative of are lacking to investigate the effects traumatic damage organs tissues. Here we describe three-dimensional vitro model high strain rate loading seen blast injury. Method 3D printing resins were tested Young's Modulus & Poisson Ratio using universal tes...

Patient-specific instrumentation (PSI) enables better restoration of the mechanical axis in total knee replacement (TKR) than conventional instrumentation (alignment guides) does. We verified the accuracy of the PSI by computer navigation. The PSI jigs were accurate only if they were pinned accurately onto the distal femur and proximal tibia. Any slight malposition of the jigs leads to malalign...

This paper describes some methods for producing developable surfaces with practical applications for creating useful lightweight, rigid, jig-less and elegant structural forms from sheet materials. Multiple related techniques based on the same fundamental principle can be used to generate a variety of interesting singly curved and doubly curved shapes. The system requires a minimum of specialist...

selecting an appropriate manufacturing machine is a very important and complex problem for firms, which usually have to deal with both qualitative and quantitative criteria. taking into account the differences among machines in terms of cost, speed, quality and after sale services, type and number of machines are important parameters to consider. therefore, the goal of this paper is to propose ...

In this paper, we propose an occupant sensing system using the sensor fusion composing of PIR (pyroelectric infrared) sensor, USD (ultrasonic distance) sensor and IRD (infrared distance) sensor for the smart airbag. These sensors are used to detect the position and body classification of occupants. By mounting these sensors within vehicles jig, the proposed system is experimentally evaluated in...

Methods: Three different methods for partial canine retraction were evaluated: retraction with elastic chain directly attached to bracket; elastic chain connected to bracket hook and with sliding jig activated with the aid of an elastic chain attached to a mini-implant. For this evaluation, a Typodont was adapted to simulate the desired movements when exposed to a heat source. After obtaining t...
