Feasibility of mini-implant insertion between mesial and distal buccal roots of a maxillary first molar: A cone-beam computed tomography imaging study.

Introduction: Mini-implant insertion in the maxillary posterior region can be influenced by anatomic limitations, thus increasing the failure rate. We explored the feasibility of a new implantation site: the region between the mesial and distal buccal roots of the maxillary first molar.

Methods: Cone-beam computed tomography data from 177 patients were collected from a database.

Clinical analysis of successful insertion of orthodontic mini-implants in infrazygomatic crest.

Background: The insertion positions of mini-implant in infrazygomatic crest has been reported, but due to the anatomical variation, the precise location of this site is not clear yet. This study used cone-beam computed tomography (CBCT) to analyze the position and angle of mini-implants successfully inserted in the infrazygomatic crest, with the goal of providing reference data for clinical practice.

Methods: CBCT was used to image 40 mini-implants and their surrounding tissues in adult orthodontic patients who successfully underwent mini-implant insertion in the infrazygomatic crest.

Investigation of periodontal status and bacterial composition aroundmini-implants.

Introduction: Mini-implants are now widely used in orthodontic treatment. Soft-tissue inflammation around the mini-implant is an important factor affecting its stability. This study aimed to investigate the periodontal status and the bacterial composition around mini-implants.

secretion leads to dysplasia of normal esophageal epithelial cells the Sonic hedgehog pathway.

Objectives: To investigate the pathogenic effect of cultured media on the esophagus and the mechanism underlying the effect.

Background: Periodontitis is strongly associated with esophageal squamous cell carcinoma (ESCC). The cultured media of may act on healthy esophagus to trigger a malignant transformation; however, this has not been confirmed.
