Suture Anchor and Reverse Suture Anchor show Superior Biomechanical Efficacy to Transtibial Pull-out Repair for Posterior Medial Meniscus Root Tears in Porcine Model.

Purpose: To investigate the biomechanical efficacy of the reverse suture anchor (RSA) technique compared with the transtibial pull-out (TP) and suture anchor (SA) techniques using in vitro porcine knee models of PMMRTs.

Methods: 32 fresh frozen porcine tibiae with medial meniscus intact were randomly assigned to four groups (eight specimens each). A standardized posterior medial meniscus root tear (PMMRT) was established in 24 specimens.

Predicting temporomandibular disorders in adults using interpretable machine learning methods: a model development and validation study.

Introduction: Temporomandibular disorders (TMD) have a high prevalence and complex etiology. The purpose of this study was to apply a machine learning (ML) approach to identify risk factors for the occurrence of TMD in adults and to develop and validate an interpretable predictive model for the risk of TMD in adults.

Methods: A total of 949 adults who underwent oral examinations were enrolled in our study.

A nomogram for predicting the risk of temporomandibular disorders in university students.

Objectives: Temporomandibular disorders (TMDs) have a relatively high prevalence among university students. This study aimed to identify independent risk factors for TMD in university students and develop an effective risk prediction model.

Methods: This study included 1,122 university students from four universities in Changchun City, Jilin Province, as subjects.

The displacement of teeth and stress distribution on periodontal ligament under different upper incisors proclination with clear aligner in cases of extraction: a finite element study.

Objectives: To investigate the displacement of dentition and stress distribution on periodontal ligament (PDL) during retraction and intrusion of anterior teeth under different proclination of incisors using clear aligner (CA) in cases involving extraction of the first premolars.

Methods: Models were constructed, consisting of the maxilla, PDLs, CA and maxillary dentition without first premolars. These models were then imported to finite element analysis (FEA) software.

Three-dimensional finite element study of mandibular first molar distalization with clear aligner.

Objectives: This study aimed to construct the finite element model of the mandibular first molar with the invisible appliance and explore the dentition movement characteristics of the mandibular first molar when using micro-implant anchorage and different initial positions of the first molar.

Methods: Models of the mandible, tooth, periodontal membrane, and invisible appliance were constructed using cone beam computed tomography (CBCT) data. The two groups were divided into the non-anchorage group and the micro-implant group (between the roots of the first molar and the second molar) based on whether the elastic traction of the micro-implant was assisted or not.

Mandibular advancement with clear aligners and functional appliances in the treatment of skeletal ClassⅡmalocclusion: a systematic review and meta-analysis.

Objectives: This study aimed to conduct a meta-analysis of the efficacy of mandibular advance clear alig-ners with traditional functional appliances as the control group.

Methods: PubMed, Web of Science, Embase, Cochrane Library, China Biomedical Abstracts Database, China Knowledge Network Database, Wanfang Database, and Weipu Database were used in this study. The two groups of researchers screened the literature and extracted data based on the inclusion and exclusion criteria established by PICOS entries, and used the ROBINS-I scale for quality evaluation.

Repair of rotator cuff tears in patients aged 75 years and older: Does it make sense? A systematic review.

Background: Rotator cuff injuries are common, and morbidity increases with age. The asymptomatic full-thickness tear rate is 40% in the over 75-year-old population.

Purpose: This study aimed to systematically review the literature on the outcomes of rotator cuff repair among >75 years old patients.
