o bjectives: the aim of this study was to investigate the displacement and stress distri- bution during surgically assisted rapid maxillary expansion under different surgical conditions with tooth- and bone-borne devices. materials and methods: three-dimensional (3d) finite element model of a maxilla was constructed and an expansion force of 100 n was applied to the left and right molars and pr...

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...

Introduction: Maxillary sinuses are among the largest paranasal sinuses with various shapes and volumes. The dimensions and volumes of maxillary sinuses play an important role in the surgical treatment plan. The higher levels of pneumatization of alveolar bone lead to the increase of odontogenic sinusitis which cause problems in dental implantation. Therefore, this study aimed to evaluate...

Maxillary transverse discrepancy usually requires expansion of the palate by a combination of orthopedic and orthodontic tooth movements. Three expansion treatment modalities are used today: rapid maxillary expansion, slow maxillary expansion and surgically assisted maxillary expansion.This article aims to review the maxillary expansion by all the three modalities and a brief on commonly used a...

Introdouction: Cone-beam computed tomography (CBCT) scanning is a technological innovation developed in recent years with potential use in oral surgery and many other dental procedures. The aim of this study is to determine the maxillary sinus mucosal thickening in the maxillary premolar-molar area using the CBCT technique. Materials and methods: In this retrospective study, a total of 105 c...

BACKGROUND We report a rare case of fatty tissue within the maxillary sinus in a 21-year-old woman, with a history of several previous punctures of the maxillary sinus. CASE PRESENTATION Clinical data of the patient was analysed retrospectively. The patient presented with symptoms of left-sided chronic maxillary sinusitis and had undergone several punctures of the left maxillary sinus 18 mont...

AIM The purpose of this report is to present two cases of totally impacted maxillary deciduous molars, considered a rarity in dental practice. BACKGROUND Primary tooth impaction is quite rare during the development of primary dentition. Various factors contribute to the impaction of a deciduous tooth, including anklyosis, congenitally missing permanent teeth, defects in the periodontal membra...

The purpose of this study was to investigate the possible predictors success microimplant-assisted rapid palatal expansion (MARPE) in skeletally mature patients. Additionally, factors associated with amount maxillary were analyzed. Factors MARPE analyzed 53 adult patients (27 males, 26 females, mean age 25.8 ± 8.9 years, and range 18.0 56.6 years) who had a transverse deficiency greater than 2 ...
