Filter by:Orthodontic appliances can affect changes in the relationships of members of the oral microbiome. Microbiome imbalance can result in oral infections and complicate treatment. The focus is on the microbiological profile of dental biofilm and its control. The effects of metals released by corrosion of alloys for oral use on the microbiome and the extent to which they modify the effectiveness of gingivitis therapy by mechanical and chemical control of biofilm will be investigated. Early and late colonizers of the tooth surface will be analyzed. The condition of gingiva will be assessed, and the results will show the specifics of biofilm and gingiva exposed and unexposed, and differences in the response of individual bacteria to therapy. Molecular biology techniques will be used to quantify the total bacterial biomass (16s rRNA) and the proportion of specific bacterial species within the dental biofilm.
Patients who have severe crowding that requires four premolars extraction will be treated in this study. The efficacy and effectiveness of in-house clear aligners therapy compared with vestibular fixed appliances in the treatment of severe crowding malocclusion cases requiring the extraction of first premolars will be evaluated using Little's irregularity index (LII), Peer assessment rating index (PAR), and treatment duration. There are two groups: First group (Experimental): the patients in this group will be treated using clear aligners. Second group (Control): the patients in this group will be treated using fixed appliances.
Carriere Motion appliance (CMA) was designed to change a Class II molar relationship into a Class I relationship by distalizing the whole posterior maxillary segment by means of class II elastics and mandibular anchorage. To eliminate the adverse effects of CMA with class II elastics, we can use the CMA to distalize the maxillary posterior segment with intra-arch anchorage using infrazygomatic miniscrews. The aim of this study is to evaluate skeletaly anchored CMA for distalization of the maxillary buccal segment vs. conventionally anchored CMA by comparing skeletal and dental measurements obtained from lateral cephalometric radiographs obtained prior to treatment (T0) and immediately after correction of class II and remval of the appliance (T1).
This study will aim to evaluate the effect of skeletally anchored extrusion arch on the dentofacial structures in patients with anterior open bite (AOB).
Objective: To compare the cementation precision of self-ligating brackets between two indirect bonding materials: polyvinylsiloxane and thermal glue. Methods: Split-mouth randomized clinical trial study, with 15 participants. The study will be divided into two groups, Group 1: Polyvinylsiloxane and Group 2: Thermal glue.
the PowerScope appliance is found to be efficient for the treatment of class II malocclusion. Accordingly, it appears valuable to investigate the efficiency of skeletally anchored powerScope in the treatment of class III malocclusion
this study was to compare the changes in arch parameters after molar distalization; hybrid hyrax distalizer versus Pendulum distalizer using CBCT.
To evaluate the effect of the low power density 940nm diode laser in the total relief of dental crowding during the alignment phase and the perception of pain in patients who initiate orthodontic treatment.
There is currently no information on how mandibular advancement therapy could influence three-dimensionally the condylar and mandibular morphology in growing patients affected by Juvenile Idiopathic Arthritis (JIA). Therefore, the aim is to assess the three-dimensional morphological mandibular changes produced by the Invisalign® Mandibular Advancement (MA) (Align Technology, San José, CA, USA) in growing subjects affected by juvenile idiopathic arthritis with unilateral and bilateral JIA and to compare them with not-JIA control subjects
This study will be directed to evaluate The effect of two different types of fixed functional appliances on the temporomandibular joint. Study design: Prospective randomized clinical study. Study setting and population: This study will be conducted on twenty orthodontic patients. The number of patients was dependent on a power study. Sample size calculation was based on the observed average effect size derived from previous article addressing "the effect of skeletally anchored Forsus FRD using miniplates for the treatment of Class II malocclusion
