Facial soft tissue esthetics is a priority in orthodontic treatment, and emerging of the digital technologies can offer new methods to help orthodontist toward an esthetic outcome. This prospective study aimed assess changes face after six months retention following Rapid Maxillary Expansion (RME). The sample consisted 25 patients (13 females, 12 males, mean age: 11.6 years) who presented with ...

OBJECTIVE To evaluate the changes in cortical bone thickness, alveolar bone height, and the incidence of dehiscence and fenestration in the surrounding alveolar bone of posterior teeth after rapid maxillary expansion (RME) treatment using cone-beam computed tomography (CBCT). METHODS The CBCT records of 20 subjects (9 boys, mean age: 13.97 ± 1.17 years; 11 girls, mean age: 13.53 ± 2.12 year) ...

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...

Introduction: Maxillary constriction is a dentoskeletal deformity characterized by discrepancy in maxilla/mandible relationship in the transverse plane, which may be associated with respiratory dysfunction. Objective: The objective of this study was to evaluate the skeletal effects of RME on maxillary and nasal transverse dimensions and compare the differences between males and females. Me...

INTRODUCTION The aim of this study was to apply low-dose computed tomography (CT) to evaluate treatment and posttreatment effects produced by rapid maxillary expansion (RME) at the levels of the midpalatal suture and the pterygoid processes. METHODS A sample of 17 subjects (7 boys, 10 girls; mean age, 11.2 years) was analyzed. Multi-slice CT scans were taken before RME, at the end of the acti...

Objective: This study aimed to compare the skeletal and dentoalveolar effects of expansion force created by semi-rapid rapid activation protocols. Material Methods: The comprised 54 patients (26 female 28 male) with transverse maxillary insufficiency. Of these patients, 22 were treated (SRME) 32 (RME). SRME group consisted 6 prepubertal, 8 pubertal, postpubertal RME 11 10 patients. Treatment bo...

The present study evaluated rapid maxillary expansion (RME) periodontal effects by means of computed tomography (CT), comparing the tooth-tissue-borne and the tooth-borne expanders. The sample comprised 8 girls aged between 11 to 14 years, presenting with Class I or II malocclusions with unilateral or bilateral posterior crossbite. The sample was randomly divided into two treatment groups (Haas...

BACKGROUND The study aimed to evaluate and compare the stress distribution and 3-dimensional displacements along the craniofacial sutures in between the Rapid maxillary Expansion (RME) and Implant supported RME (I-RME). METHODS: Finite element model of the skull and the implants were created using ANSYS software. The finite element model thus built composed of 537692 elements and 115694 nodes ...

Introduction: The palatal expansion may be a challenging treatment in late adolescents who has passed the peak of skeletal growth. success rate these patients decreases due to decreased growth potential.
 Aim: It was aimed determine any clinical/radiological indicator used as predictor failure rapid maxillary (RME) adolescence.
 Materials and methods: records had undergone RME therapy...

Post-retention effects of rapid maxillary expansion on nasal cavity and on periodontal structures Aim. The aim of this study was to apply low-dose CT scans to evaluate the treatment and post-retention effects of RME on nasal cavity and periodontal effects. Materials and methods. CT scans of 17 subjects (7 males 10 females, mean age 11.2 years) were taken before RME (T0), at the end of the expan...
