Does Rapid Maxillary Expansion Affect the Eruption of Upper Third Molars?

Effect of extraction of permanent first molars on the development and eruption of third molars

BACKGROUND AND AIM: It is required in many young patients that permanent first molars (PFMs) be extracted due to poor prognosis. This study investigates whether the extraction of such teeth is effective on the development of third molars and even their crown and root morphologies.METHODS: A total of 7000 panoramic radiographs were evaluated and 128 radiographs showing a history of extraction of...

Eruption of third molars: relationship to inclination of adjacent molars.

The purpose of this study was to determine the relationship between the sagittal inclination of the first and second maxillary molars and the eruption of the third molars. The sample consisted of 2 groups. The subjects in the first group (n = 28) had complete normal dentitions including third molars; those in the second group (n = 32) had impacted right and left third molars. The sagittal incli...

Delayed eruption of maxillary permanent first and second molars due to an ectopically positioned maxillary third molar.

Association between ectopic eruption of maxillary canines and first molars.

The purpose of this study was to elucidate a possible association between ectopic first molar eruption causing root resorption on the distal root of the primary maxillary second molar, and ectopic canine eruption causing root resorption on the permanent maxillary incisors. The subjects consisted of 30 patients, 22 females and eight males in the age range 8.3-15.0 years in whom root resorption o...

Bone-Borne Maxillary Expansion and Traditional Rapid Maxillary Expansion: A Systematic Review and Meta-Analysis

Introduction: The aim of this study was to perform a systematic review and meta-analysis to compare the effect of bone-borne expansion (BBE) and tooth-borne expansion (TBE) in patients with maxillary constriction. Methods: Electronic databases, including MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials, were searched up to February 2019. Elig...
