Influence of conventional and skeletal anchorage system supported fixed functional appliance on maxillo-mandibular complex and temporomandibular joint: A preliminary comparative cone beam computed tomography study.

Aim: Fixed functional appliance (FFA) used in the treatment of Class II malocclusion, lead to mandibular anterior teeth proclination, thus limiting the skeletal effects of the appliance. To counter this side effect, FFA is anchored in the lower anterior region of the mandible using the skeletal anchorage system. This pilot study was done to evaluate treatment and one-year post-treatment maxillo-mandibular, and temporomandibular joint (TMJ) effects of conventional fixed functional appliance (FFA) and skeletal anchorage system supported fixed functional appliance (SAS-FFA) using cone beam computed tomography (CBCT) images.

Comparison of speech performance in labial and lingual orthodontic patients: A prospective study.

Background: The intensity and duration of speech difficulty inherently associated with lingual therapy is a significant issue of concern in orthodontics. This study was designed to evaluate and to compare the duration of changes in speech between labial and lingual orthodontics.

Materials And Methods: A prospective longitudinal clinical study was designed to assess speech of 24 patients undergoing labial or lingual orthodontic treatment.

Volumetric pulp changes after orthodontic treatment determined by cone-beam computed tomography.

Introduction: The purpose of this study was to observe and evaluate 3-dimensional pulp cavity changes during orthodontic treatment.

Methods: Eighty-seven patients formed the study sample and were divided into an experimental group (48 patients) and a control group (39 patients). Cone-beam computed tomographic (CBCT) records were obtained before the start of the treatment (T0) and after space closure for the experimental group, whereas for the control group CBCT images were obtained approximately 17-18 months (T1) after obtaining the first image (T0).

A camouflage treatment of Class II division 1 malocclusion complicated by missing lateral incisor.

This case report describes the treatment of a male patient, aged 16 years and 5 months, with a Class II division 1 malocclusion, who showed severe anterior protrusion and lower anterior crowding along with missing upper left lateral incisor. Treatment plan consisted of extraction of upper right first premolar and lower second premolars. No extraction was performed on the upper left quadrant instead canine was substituted as lateral incisor and premolar as canine to establish a good occlusion.

Quantitative assessment of interradicular bone density in the maxilla and mandible: implications in clinical orthodontics.

Background: Bone density at the interradicular area plays an important role during orthodontic treatment. In view of this fact, the study was designed to quantitatively evaluate the bone density at the interradicular areas of the alveolar and basal bones of maxilla and mandible by computed tomography.

Methods: One hundred and nine computed tomographic images were randomly selected, and bone density was measured in Hounsfield units (HU) with bone mineral density software (Siemens VA20A_SP3A).

Comparison of the effects of ibuprofen and acetaminophen on PGE2 levels in the GCF during orthodontic tooth movement: a human study.

Background: Pain is among the most cited negative effects of orthodontic treatment. Non-steroidal anti-inflammatory drugs seem to be an effective option for minimizing this but can have adverse effects on tooth movement owing to their ability to block prostaglandin synthesis. Acetaminophen has been suggested as the analgesic of choice during orthodontic treatment as it showed no effect on orthodontic tooth movement in previous animal studies.

Non-extraction treatment of skeletal class II malocclusion.

Every orthodontist at some point in his clinical practice has faced the dilemma of how 'best' to manage a mild to moderate Class II malocclusion. To demonstrate the efficacy of Forsus™ Fatigue Resistant Device in the management of Class II malocclusion. A patient having Class II division 1 malocclusion with functional jaw retrusion was treated using MBT 0.

Comparison of different parameters for recording sagittal maxillo mandibular relation using natural head posture: A cephalometric study.

Background: Commonly used parameters for anteroposterior assessment of the jaw relationship includes several analyses such as ANB, NA-Pog, AB-NPog, Wits appraisal, Harvold's unit length difference, Beta angle. Considering the fact that there are several parameters (with different range and values) which account for sagittal relation, and still the published literature for comparisons and correlation of these measurements is scarce. Therefore, the objective of this study was to correlate these values in subjects of Indian origin.

Evaluation of Parental Nasomaxillary Asymmetry as a Risk Factor for Development of Palatal Clefts in their Offsprings.

Background and Objectives : It has been suggested previously that increased width of midfacial structure is associated with the development of palatal clefting. One of the most important heritable characteristics predisposing towards the development of orofacial clefting in an embryo is craniofacial morphology. The aim of the study was to compare nasomaxillary width of parents of children with unilateral complete cleft lip alveolus and palate with parents of noncleft children.

WiPics: wireless and beyond.

A WiPics transmitter allows wireless tranfer of images from the camera to the computer as the photos are being shot. This article describes this novel technological approach and its application in orthodontic imaging.

Correction of a severe skeletal Class II occlusion with a fixed functional appliance anchored on mini-implants: a patient report.

This report describes the treatment of a patient with a severe skeletal Angle Class II occlusion with a 14-mm overjet, crowding, and protrusion of the mandibular anterior teeth. The Class II relationship was caused mainly by a short corpus of the mandible. A fixed functional appliance was directly anchored on mini-implants, which were inserted in the mandible.

"Oops, I deleted it"--a solution for recovering deleted or reformatted digital images from memory cards.

Capturing patient photographs on digital flash cards rather than film has several advantages, but also a few disadvantages. Among the latter, the primary disadvantage is the possibility of accidentally deleting or corruping the files before they are downloaded from the memory card. In this article, we describe utilities that enable image recovery from deleted, reformatted, or physically damaged flash memory cards.
