Dental aesthetics have become highly important nowadays. Treating aesthetic needs with non-invasive and minimal techniques can preserve tissues. Invisalign aligners are an comfortable option too for orthodontic treatment. The increased demand treatment in adults has widened the upper age limit intervention. antero-posterior skeletal relationship of maxilla mandible is determined by ANB angle. V...

Abstract Lanthanide doped nanocrystals capable to emit higher energy photons under excitation with lower radiation are promising for a broad range of applications including biodetection, biosensing, and bioimaging. However, the adaptation these nanoparticles biological environment that requires good water-solubility, stability ease further functionalization still remains challenge. The applicat...

Materials and methods: A 10-year-old male patient, in the mixed dentition stage, presented with anterior crossbite, Class I skeletal base with an ANB angle of 1 degree, retroclined maxillary incisors and an anterior mandibular slide from the point of initial contact to maximum intercuspation. A modified quad helix appliance, made of 0.036" Blue Elgiloy with anterior extension arms, was fabricat...

Early treatment for Class II malocclusion was undertaken with the objective of correcting skeletal disproportion by altering the growth pattern. A case of Class II, Division 1 malocclusion in the mixed dentition was corrected to Class I molar relationship using orthopedic cervical headgear, with nonextraction edgewise therapy. Cephalometric analysis indicated a reduction in the maxillomandibula...

In a cross-sectional cephalometric study of over 800 normal white American children we show that the average ANB angle is roughly twice as large as the currently employed norms for that variable. The angle is relatively the same in females from 6 to 20 years of age, but there is a definite tendency for older males to exhibit a smaller ANB angle. The dynamics of this decrease is essentially the ...

The accessory navicular bone (ANB) is a secondary ossification center of the navicular bone and is rarely observed. Three distinct types of accessory navicular bones have been described. The type III, known as the cornuate navicular, is a rare morphological entity of the accessory navicular bone. We report the case of a patient, 48 years old, who presented with chronic swelling and pain in her ...

Introduction:Orthodontic treatment is associted with a risk of root resorption.The aim of this study was to determine the risk of moderate and sever root resorption in orthodontic patients treated with fixed orthodontic appliance.   Method:A case-control study was performed on 70 orthodontic treated patients with moderate and sever root resorption and 70 controls matched for age,sex,duration ...

Materiales métodos: estudio enfoque cuantitativo, relacional, retrospectivo corte transversal. La muestra estuvo conformada por 400 radiografías cefálicas laterales años, se determinó biotipofacial mediante índice Vert, clase esqueletal ángulo...

the painful nature of fractures has made it inevitable to use various anesthetic techniques to reduce or immobilize fractured parts. in the present study, axillary nerve block was compared with intravenous midazolam/fentanyl to induce anesthesia for painless reduction of upper extremity fractures. the subjects in the present clinical trial consisted of 60 patients with upper extremity fractures...
