This paper proposes a service-centric framework for the feature interaction problem in integrated services of the home network system (HNS). To formalize the HNS, we extensively use an object-oriented approach where each networked appliance (or the HNS environment) is modeled as an object consisting of properties and methods. Based on the model, we define two types of feature interactions: appl...

INTRODUCTION The effects of orthodontic treatment are considered to be successful if the facial harmony is achieved, while the structures of soft tissue profile are in harmony with skeletal structures of neurocranium and viscerocranium. In patients with skeletal distal bite caused by mandibular retrognathism, facial esthetics is disturbed often, in terms of pronounced convexity of the profile a...

Tongue thrusting and thumb sucking are the most commonly seen oral habits which act as the major etiological factors in the development of dental malocclusion. This case report describes a fixed habit correcting appliance, Hybrid Habit Correcting Appliance (HHCA), designed to eliminate these habits. This hybrid appliance is effective in less compliant patients and if desired can be used along w...

The 2 x 4 appliance comprises bonds on the maxillary incisors, bands on the first permanent maxillary molars and a continuous archwire. The appliance is used in the early mixed dentition for treatment of both anterior crossbites and alignment of ectopic incisors. Four cases using this appliance are presented. This appliance offers many advantages over alternative techniques as it provides compl...

AIM To evaluate the dentoskeletal effects produced by Fränkel-2 (FR-2) appliance during the treatment of patients with Class II malocclusion by mandibular retrusion and to verify the long-term stability of these changes. MATERIALS AND METHODS Pre-treatment, post-treatment and long-term serial cephalograms (at least 10 years after the end of treatment) of patients treated with FR-2 were comp...

abstract background: the aim of this study is to evaluate the dimensional accuracy of mbt (mclaughlin, bennett and trevisi ) brackets manufactured by two different companies (american orthodontics and ortho organizers) and determine variations in incorporation of values in relation to tip and torque in these products. methods: in the present analytical/descriptive study, sixty-four maxillary ri...

Objectives: An appliance to correct unilateral Class II molar relationship was described, the clinical and laboratory procedures for the construction of the appliance were explained. The clinical application for the unilateral molar distalization was illustrated by a case report. Other methods of distalizaton were reviewed and compared with the present appliance. The advantages and disadvantage...

Oral appliance therapy is an alternative to continuous positive airway pressure (CPAP) for treating the obstructive sleep apnea-hypopnea syndrome. However, the ability to pre-select suitable candidates for either treatment is limited. The aim of this study was to assess the value of relevant variables that can predict the outcome of oral appliance and CPAP therapy. Fifty-one patients treated wi...

the present report describes orthodontic treatment of a patient with skeletal class iii malocclusion and maxillary hypoplasia. to correct the retrusive maxilla, the treatment plan included an intra-oral removable device. it had the advantages of good patient cooperation, ease of construction and effective modification. forward growth of the maxilla, minimal downward and backward rotation of the...

INTRODUCTION Maxillary canine-first premolar transposition (Mx.C.P1) is an uncommon dental positional anomaly that may create many orthodontic problems from both esthetic and functional points of view. OBJECTIVE In this report we show the orthodontic management of a case of Mx.C.P1 associated with bilateral maxillary lateral incisor agenesis and unilateral mandibular second premolar agenesis ...
