precise registering and transferring of the selected path of insertion and withdrawal of removable, partial dentures is a critical step in designing and fabricating their framework and determining the retention, stability, and support of the completed prosthesis. many authors have addressed this issue in their studies. in this study we present a new technique for registering and reproducing par...

We characterize the removability of Hölder-α graphs with respect to continuous Sobolev W 1,2 functions. For α > 2/3 these graphs are removable, while for α < 2/3 there exist graphs which are not removable.

We address the redundancy allocation of a series repairable system with multiple k-out-of-n subsystems with each subsystem following shut-off rule. The objective of the problem is to find the optimal number of repairmen and redundant components in each subsystem for optimization of steady-state availability subject to weight, cost and volume constraints. We propose a Particle Swarm Optimization...

Lack of adequate support (tooth/soft tissue) results in displacement of bilateral and unilateral distal extension removable partial dentures. Placement of implants is one option for managing this problem. The aim of this report is to describe fabrication of a mandibular removable partial denture supported by 2 unilateral distal implants with locater attachments. The patient was a 70-year-old ma...

The absence of lower posterior teeth makes the planning and control of removable partial dentures difficult since support is provided by teeth and mucosa, which present different anatomical characteristics. The planning of removable partial dentures supported on a distal implant renders tooth-implant-supported rather than tooth-mucosa-support dentures an option in distal extension cases. In the...

In a classic 1978 Memory & Cognition article, Geoff Loftus explained why noncrossover interactions are removable. These removable interactions are tied to the scale of measurement for the dependent variable and therefore do not allow unambiguous conclusions about latent psychological processes. In the present article, we present concrete examples of how this insight help...

A removable edge in a 3−connected cubic graph G is an edge e = uv such that the cubic graph obtained from G \ {u, v} by adding an edge between the two neighbours of u distinct from v and an edge between the two neighbours of v disctinct from u is still 3−connected. Li and Wu [3] showed that a spanning tree in a 3−connected cubic graph avoids at least two removable edges, and Kang, Li and Wu [4]...

background  and  objectives:  long-term  usage  of  fixed and  removable  orthodontic  appliances  creates  a  favorable environment for the augmentation of oral normal microflora particularly candida species, which can increases the risk of periodontal lesions. the aim of this study was to assess quantitative and qualitative alterations in the carrier rate of candida spp. after placement of fi...

A collaboration between the developer of a Removable Hard Disk Drive (RHDD) storage technology product and academics presents an accelerated life test of non-spinning powered down hard disks. The results are used to predict the reliability of removable disk cartridges stored in shirtsleeve environments as archival media. The contributions of this paper include an initial study of the reliabilit...

the routine treatment for rotated maxillary incisor is a fi xed appliance, but in some instance the use of this method is impossible. in addition, in only limited cases of rotation, removable appliance is applicable. in this study, the use of a semi-removable appliance is presented, which has some benefi ts over the other methods. in this study, the corrections of about 70 -90° rotation of the ...
