BACKGROUND This study compared the oral hygiene and caries risk of patients treated with labial and lingual orthodontic appliances throughout a prospective evaluation of the status of the oral environment before and after bracket placement. METHODS A total of 20 orthodontic patients aged 19 to 23 years were included in the study and were divided into two groups: 10 patients wore Roth labial a...

Objective: The aim of this study was to analyze quantitatively the serum fluid levels of nickel and chromium in orthodontically treated patients due to biodegradation of the appliance over a period of time using an inductively coupled plasma emission spectrometry (ICP). Materials and methods: This cross-sectional study included 24 patients undergoing Begg’s fixed appliance mechanotherapy betwee...

There is still controversy regarding the efficacy of functional appliances when treating malocclusion at an early age. Although a good outcome from treatment is important, the stability of the results over time becomes a major concern. This paper presents the results of three open bite cases treated with the Bimler type-A appliance in the mixed dentition. The open bite cases presented here demo...

Non-intrusive appliance load monitoring is the process of breaking down a household’s total electricity consumption into its contributing appliances. In this paper we propose an approach by which individual appliances are iteratively separated from the aggregate load. Our approach does not require training data to be collected by sub-metering individual appliances. Instead, prior models of gene...

The purpose of this article is to introduce a simple appliance that uses a setup model and a nickel-titanium (Ni-Ti) wire for correcting the mesial rotation and drift of the permanent maxillary first molar. The technique involves bonding a Ni-Ti wire to the proper position of the target tooth on a setup model, followed by the fabrication of the transfer cap for indirect bonding and its transfer...

Anterior sectional twin bracket appliance (ASTBA) is a sectional mechanism that involves two brackets on upper central incisors. This appliance is previously been used for correction of rotated incisors and midline spacing. But, detail biomechanics for single tooth crossbite correction is not previously explained. Here, in this article, we are presenting a detailed biomechanics of ASTBA for ant...

Pseudo Class III malocclusion is characterized by an anterior crossbite with functional forward mandibular displacement. Various appliances have been devised for early treatment of a pseudo Class III. The aim of this article is to highlight the method of construction and use a simple removable appliance termed as "Modified Hawleys appliance with inverted labial bow" to treat psuedo class III ma...

Recently, smartphones have been used as remote controllers for home appliances through connectivity of mobile telecom network or Wi-Fi. To control several home appliances in a room, a mechanism is required for a smartphone to correctly select the target appliance. Through the built-in electronic compass function in the smartphone, we propose a scheme called Point-and-Control (PnC) that allows a...

Twin Block appliance has been widely used for the treatment of Class II malocclusions in growing subjects, due to its versatility and its highly compliance nature. There are certain clinical indications where functional appliances can be used successfully in Class II malocclusion as in a growing patient. In using these appliances, the main concern is compliance of patients. This appliance simpl...

The plug-in electric vehicle (PEV) has attracted more and more attention because of the energy crisis and environmental pollution, which is also the main shiftable load of the residential users’ demand side management (DSM) system in the future smart grid (SG). In this paper, we employ game theory to provide an autonomous energy management system among residential users considering selling ener...
