OBJECTIVES/HYPOTHESIS Determine the feasibility and accuracy of using virtual surgical planning (VSP) to direct the surgical and polysomnography (PSG) outcomes of patients with obstructive sleep apnea (OSA). STUDY DESIGN Prospective case series. METHODS Skeletal and soft tissue dimensions were measured from computed tomography (CT) to include posterior airway space (PAS) diameters at the oc...

PURPOSE The aim of this study was to evaluate the clinical response and safety of immediately loaded single-tooth implants placed in the posterior region of the maxilla and mandible. MATERIALS AND METHODS Single-tooth implants were placed in healed extraction sites in 20 adult patients. Temporary pre-fabricated acrylic resin crowns were prepared and adjusted. The crown occlusion was adjusted ...

A dentigerous cyst is a benign lesion arising from the odontogenic epithelium associated with crown of an impacted tooth. They are radiolucent and unilocular, usually asymptomatic diagnosed in clinical routine or radiographic examinations. The lower third molars upper canines most affected teeth, also odontomas supernumerary teeth. slow-growing but can reach considerable dimensions, causing fac...

Parathyroid hormone (PTH)-related protein (PTHrP)-knockout mice die at birth with a chondrodystrophic phenotype characterized by premature chondrocyte differentiation and accelerated bone formation, whereas overexpression of PTHrP in the chondrocytes of transgenic mice produces a delay in chondrocyte maturation and endochondral ossification. Replacement of PTHrP expression in the chondrocytes o...

INTRODUCTION Orthodontic-surgical treatment was performed in patient with skeletal Class III malocclusion due to exceeding mandibular growth. Patient also presented upper and lower dental protrusion, overjet of -3.0 mm, overbite of -1.0 mm, congenital absence of tooth #22, teeth #13 and supernumerary impaction, tooth #12 with conoid shape and partly erupted in supraversion, prolonged retention ...

AIM The aim of this report was to show the management of a case with an impacted central maxillary incisor caused by odontoma in a young patient with two mesiodentes in the region of the nasal floor. CASE REPORT A 9-year-old girl was seen in the Department of Orthodontics of the University of Rome 'Tor Vergata'. Radiographic images showed intraosseous impaction of the maxillary right central ...

S upernumerary teeth occur most commonly in the maxillary anterior region. When in the midline area, such a tooth is commonly referred to as a mesiodens with most remaining unerupted. 1, 2 The prevalence of supernumerary teeth is reported to be from I to 3%. 3‘4 Supernumerary teeth may cause or be related to over-retention of primary teeth, impaction, or ectopic eruption of nearby permanent tee...

The purpose of this study was to evaluate the position and aspects of maxillary canine impactions in the Korean population and investigate its comparison with the previous reports, while aiding in the establishment of diagnosis and treatment planning by revealing the influential factors of root resorption associated with such impactions. The subjects of this study consisted of 186 teeth from 14...
