an impacted tooth can be performed with either fixed or removable appliances. Fixed appliances do not require special patient cooperation and can produce precise coronal and root movements.1,2 On the other hand, the wire attached to the impacted tooth may be more easily deflected than with removable appliances, causing undesirable movements of adjacent teeth.3 Such movements are minimized with ...

UNLABELLED While utilizing removable dentures, regardless of whether the dentures are acrylic or fabricated of eclipse resin, the need for their filling-relining or their repair frequently arises. The purpose of this study is to display the technicalities of the procedure for rebasing and relining of removable light curing eclipse denture resin. MATERIAL AND METHODS This study presents cases ...

A group of destructive changes occurring in jaws in patients with maxillary complete dentures and mandibular removable partial dentures (bilaterally) has been described in the literature as the combination syndrome. However, this condition is not clinically observed in all patients. The aim of this study was to establish the prevalence index on signs of combination syndrome and to verify whethe...

The paper deals with a development of the rolling horizon approach introduced recently for grouping maintenance strategies of multi-component systems by integrating two efficient optimization algorithms. The proposed approach can help to construct an optimal maintenance planning with a given availability constraint under limited repairmen. Thanks to the rolling horizon spirit, the maintenance p...

Optimal preventive maintenance and repairmen policies for a system of machines subject to degradation with age and intermittent breakdowns and repairs are derived using optimal control theory. When this system of machines forms part of a dynamic process control system, a method of obtaining optimal closed-loop control law is indicated. I . INTRODUC~ON Many large industrial systems have two dist...

We study variants of the capacitated vehicle routing problem. In the multiple depot capacitated k-travelling repairmen problem (MD-CkTRP), we have a collection of clients to be served by one vehicle in a fleet of k identical vehicles based at given depots. Each client has a given demand that must be satisfied, and each vehicle can carry a total of at most Q demand before it must resupply at its...

PURPOSE The relationship between unhealthy body mass index (BMI) and adherence to orthodontic treatment with removable appliances has not previously been evaluated. OBJECTIVE The aim of this study was to quantify the association between BMI and wear time of removable orthodontic appliances and to evaluate BMI changes during orthodontic treatment. PATIENTS AND METHODS Fifty-three normal-weig...
