This case report describes the treatment of a patient with a horizontally impacted maxillary central incisor, a canine in the same quadrant, and an inclusion tendency. Due to severe crowing in the maxilla and the Class II molar relationship on the impaction side, a 2-stage treatment plan was developed. In the first stage, the right first premolar and deciduous canine were extracted; this allowe...

statement of the problem: the stability of orthodontic treatment depends on preserving the patient’s pretreatment arch form and arch size during and after treatment. purpose: this investigation was aimed to study the size and shape of iranian mandibular dental arch and evaluate the correlation of their average dental arch with commercially available preformed rectangular nickel-titanium arch wi...

OBJECTIVES To test the applicability of the Tanaka and Johnston prediction method in a Saudi population. METHODS The current study was conducted at the College of Dentistry, King Saud University, Riyadh, Saudi Arabia from September 2013 to January 2014, on a sample of 409 pairs of orthodontic study models. The mesiodistal width of the mandibular permanent incisors, permanent canines, and perm...

BACKGROUND Few dentists have seen an impacted mandibular canine and first premolar, and there is little information in the literature on the treatment of this rare condition. CASE REPORT A 13-year-old Japanese male with an impacted mandibular right canine and first premolar was treated orthodontically. We discuss both the surgical and orthodontic options and present the successful orthodontic...

The aim of this case-control study was to test the hypothesis that maxillary morphology differs between obstructive sleep apnoea (OSA) patients and non-snoring, non-apnoeic subjects. Forty randomly selected patients [36 M, 4 F; mean age 49 +/- 2 (SEM) years] with varying degrees of OSA (mean Apnoea/Hypopnoea Index 32 +/- 4/hour) were compared with 21 non-snoring, non-apnoeic control subjects (1...

Introduction: Myectomies of the lower-lip depressor muscles, with aim to improve facial balance in unilateral paralysis, have unexplained high recurrence rates. A potential explanation is that these recurrences are due inadequate resection through muscle width, leaving lateral fibers intact. Aim: Revisit anatomy muscles and suggest an optimization surgical technique. Perform a literature review...

OBJECTIVE Orthodontic diagnosis and treatment planning for growing children must involve growth prediction, especially in the treatment of skeletal problems. Studies have shown that a strong association exists between skeletal maturity and dental calcification stages. The present study was therefore taken up to provide a simple and practical method for assessing skeletal maturity using a dental...

OBJECTIVE The aim of the study was to evaluate patients treated for impacted mandibular canines through a combined surgical and orthodontic approach. STUDY DESIGN The cases which were made button operations of impacted mandibular canines were selected from 5100 panoramic radiographs taken from patients who made use of our oral and maxillofacial surgery services between January 1998 to April 2...

The aim of this study was to evaluate the biomechanical effects of mandibular midline distraction osteogenesis on the mandibular complex by using a 3-dimensional finite element model, whose construction was based on computer tomography scans of the mandible of a 22-year-old man. The computer tomography pictures were transferred and converted to the finite element model by means of a procedure d...

A 17 years old male patient presented with impacted mandibular right canine and partially erupted left canine, overjet of 0.5mm 100% overbite. He was treated fixed orthodontic treatment disimpaction using skeletal anchorage in maxillary arch to avoid undesirable effects on dentition. Pre-treatment post records were taken evaluate the changes.
