Orthopedic appliances such as palatal expanders and facemasks have been successfully used for young patients with Class III malocclusions. A modified rapid palatal expansion (RPE) appliance in conjunction with a facemask can be used for correction of transverse and sagittal discrepancies in the initial phase of treatment for these patients.

OBJECTIVE Several appliances have been used for palatal expansion for treatment of posterior cross bite. The purpose of this study was to evaluate the stress induced in the apical and crestal alveolar bone and the pattern of tooth displacement following expansion via removable expansion plates or fixed-banded palatal expander using the finite element method (FEM) analysis. MATERIALS AND METHO...

The aim of this paper is to familiarize the readers with some of the clinical considerations necessary to ensure successful use of mid-palatal implants. Both surgical and technical aspects will be discussed along with a description of impression techniques used.

Two cases of severely atrophic maxilla with poor palatal vault form treated by Kitayama's modified palatal vault osteotomy technique are described. The advantages of this osteotomy technique are outlined in comparison with other surgical methods.

In the past, relationships in the sagittal plane have dominated orthodontic thinking to such an extent that the great majority of clinicians did not even bother to procure frontal radiographs (images, headplates). However, several factors have awakened the current clinician to a deeper interest in the transverse dimension1: (1) maxillary palatal dysjunction expansion (rapid palatal expansion [R...

The laryngeal mask airway (LMA) is an airway management device that is used to establish and maintain a patent airway for the patient. A palatal torus is a common benign bony exostosis, usually located in the midline of the palate, beneath the palatal mucosa. It should be recognized by the CRNA during the preoperative anesthetic assessment. A palatal torus can hinder insertion of the LMA when u...

Relationships between changes in arch perimeter and arch width resulting from rapid palatal expansion with the Hyrax appliance were analyzed with the use of dental study casts of 21 adolescent patients. Photographs and measurements from the dental casts obtained before treatment and approximately 3 months after stabilization were used. Regression analysis indicated that changes in premolar widt...

Conventional devices used for surgically assisted rapid palatal expansion are tooth-borne. Dental fixation entails a number of possible drawbacks such as loss of anchorage, skeletal relapse during and after the expansion period, cortical fenestration and buccal root resorption. A bone-borne titanium device with interchangeable expansion modules, used with a callous distraction policy, is presen...

BACKGROUND The aim of this experimental study was to investigate the effects of strontium ranelate on bone regeneration in the mid-palatal suture in response to rapid maxillary expansion (RME). METHODS Thirty-six male 6-week-old Wistar rats were randomly divided into three groups, ie, an expansion only (EO) group, an expansion plus strontium ranelate (SE) group, and a control group. An orthod...
