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 ...

In the idea of improving the performances of both full and removable partial dentures, new materials and technologies are coming on the market, promising a better quality. Thermoplastic materials are used more and more widely in the technology of complete or removable partial dentures due to their superior qualities. Thermoplastic resins are suitable for manufacturing a wide range of removable ...

Aim: The aim of this study was to quantify secretory immunoglobulin A (S-IgA) in the saliva of children with type 1 diabetes, asthma, no systemic disease, and no systemic disease but wearing a removable orthodontic appliance. Methods: The study recruited 116 children who had either type 1 diabetes or asthma, were systemically healthy, or were systemically healthy but wore a removable orthodonti...

Freshly coated aluminum mirrors have excellent reflectivity at far ultraviolet wavelengths. However, reflectivity rapidly degrades when the mirror surfaces are exposed to atmosphere. In order to avoid this problem, freshly coated aluminum surface can be protected by over-coating of a removable volatile protecting coating. This protecting coating can be re-evaporated by controlled heating or by ...

A compact set E ⊂ C is said to be removable for bounded analytic functions if for any open set containing E, every bounded function analytic on \ E has an analytic extension to . Analytic capacity is a notion that, in a sense, measures the size of a set as a non removable singularity. In particular, a compact set is removable if and only if its analytic capacity vanishes. The so-called Painlevé...

Using PAR index / Peer Assessment Rating Index / effectiveness of orthodontic treatment was assessed in the group of patients treated with fixed and removable appliances. The group consisted of 83 patients after the end of the active phase of treatment. 34 patients were treated with removable appliances and 49 patients were treated with fixed appliances. Patients came from three orthodontic wor...

In the present study, we analyze the multi-channel service system with ordered entryfrom finite-source and finite-storage at each channel. The arrival and service rates are assumedto be state dependent. The steady state probabilities of the system are obtained by usingChapmann-Kolmogorov equations. Some other performance indices viz. utilization of servers,expected number of units in the system...
