Introduction & Objective: The aim of this study was todeterminetheamount of external apical root resorption(EARR)within two orthodontic appliances (standard edgewise and MBT). Material & Methods In this retrospective study, panoramic radiographs of 83 orthodontic patients (27 male and 56 female) were evaluated. 46 patients had been treated with standard edgewise appliance (29 patients with e...
Obtaining long term stability allied to functional and aesthetic balance is the main goal of any orthodontic-orthopedic therapy. This case report describes the orthodontic therapy applied to a 7-year-9-month old child, who presented a Class II, division 1 malocclusion associated to skeletal open bite. Functional and skeletal corrections (sagittally and vertically) were obtained by means of mand...
Introduction: Patients receiving orthodontic treatment get some alterations in their oral cavity environment such as an increase in the levels of microorganism in oral cavity and dental biofilms. Therefore, this study aimed to evaluate as well as to compare the colonization of mutans streptococci in different parts of removable orthodontic appliances. Methods: In this descriptive analytic stu...
background and aims. this in vitro study was designed to evaluate the effect of composite resin types and orthodontic debonding pliers on the amount of adhesive remnants and enamel damages using a novel method of measurement. materials and methods. 120 extracted human premolars were randomly divided into four groups (n = 30). the standard edgewise metallic brackets were bonded to the teeth with...
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...
UNLABELLED This randomized split-mouth study was aimed at evaluating whether an orthodontic appliance per se or orthodontic tooth movement can induce detectable changes in gingival crevicular fluid (GCF) volume, and thus whether GCF volume is a predictable biomarker for tissue remodelling incident to orthodontic tooth movement. MATERIALS AND METHODS Sixteen healthy orthodontic patients (7 fem...
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 ...
Traditionally oral appliances i.e. removable orthodontic appliances, bite splints and snoring / sleep apnea appliances are made with alginate impressions and wax registrations. Our aim was to describe the process of manufacturing customized oral appliances with a new technique i.e. rapid tooling method. The appliance should ideally be custom made to match the teeth. An orthodontic patient, sche...
Relevance . For many years studies have evaluated the possibilities of modifying growth maxillofacial complex during orthodontic treatment with functional appliances. Despite large number devoted to distal occlusion in children and adolescents, there is no consensus among orthodontists on appropriateness, timing tactics such treatment. Material methods. The article presents results adolescents ...
