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...

Background: Rapid maxillary expansion (RME) is a dentofacial orthopedic treatment often used to treat patients with narrow palate and transverse growth deficiency. Introduction: This leads correction of posterior dental crossbites, coordination the upper lower arches gaining arch perimeter in tooth size/arch size discrepancies. To stabilize results obtained RME limit or avoid relapse, use Trans...

Objective: To evaluate the initial forces generated by two types of palatal expansion appliances, through fiber optic sensors, in elastomeric models. Materials and Methods: An model simulating upper dental arch was fabricated. The sensors were placed adjacent to first premolars molars roots (apical, cervical, vestibular, palatal). Hyrax Haas expanders fitted onto arch. Activation screw performe...

To evaluate and compare the speech in unilateral and bilateral cleft lip and palate children treated with and without presurgicalorthopaedics based on their palatal dimensions.Perceptual and digital evaluation of speech in cleft lip and palate childrencompared with there palatal dimensions.Twenty subjects with a history of cleft lip and palate or velopharyngeal dysfunction and speech disorder.G...

The purpose of this study was to compare the mesio-distal and vertical position impacted maxillary canines on panoramic radiographs with labio-palatal root resorption adjacent teeth CBCT (ConeBeam Computed Tomography). A total 54 patients 69 were included in study. On radiographs, (Sector I - V), position, angulation evaluated. Labio-palatal evaluated CBCT. Labial impaction most frequent sector...

OBJECTIVES To evaluate area- and gender-related differences in the soft tissue thickness of potential areas for installing miniscrews in the buccal-attached gingiva and the palatal masticatory mucosa. MATERIALS AND METHODS The sample consisted of 61 Korean young adults. An ultrasonic gingival-thickness meter was used to measure the soft-tissue thickness in the buccal-attached gingiva just adj...

STATEMENT OF THE PROBLEM Nasal breathing is the major pattern of air intake. Changes in breathing pattern alter the posture of the head, jaws and tongue that could change pressure on the jaw and teeth and affect their growth. PURPOSE This study aimed to investigate the relationship between septal deviations (SD) per se and in combination with concha bullosa (CB) on maxilla; particularly the d...

Background: to analyze the dento-alveolar effects induced by two treatment appliances (i.e., RME and Clear Aligners) in growing subjects presenting with early mixed dentition mild maxillary deficiency. Methods: digital casts of 32 children treated (RG: 17 subjects) or aligners (CAG: 15 were collected. Linear angular values measured both groups on upper arch for pre- (T1) post-treatment (T2) mod...

Premature and low birth weight infants often require neonatal oral intubation for resuscitation and to relieve respiratory distress. The endotracheal tube exerts pressure on the developing palate, which can result in palatal groove formation, a high-arched palate, and palatal asymmetry. The purpose of this investigation was to determine whether such intubation can have a long-term effect on pal...

INTRODUCTION The aim of this prospective study was to analyze the postexpansion positional changes of the maxillary halves and their initial stability after transpalatal distraction with a bone-borne distractor and standard corticotomies of the anterior, lateral, and median bony supports of the maxilla without pterygomaxillary disjunction. METHODS The sample consisted of 21 patients (15 femal...
