Remodeling of the Temporomandibular Joint After Mandibular Setback Surgery: A 3D Cephalometric Analysis.

Background: Condylar adaptations following orthognathic surgery remain an area of interest. Prior studies do not use 3-dimensional imaging modalities and lack standardization in the choice of osteotomy and movement when assessing condylar changes.

Purpose: The purpose of this study was to use 3-dimensional cephalometry to measure the association between osteotomy type (sagittal split osteotomy [SSO] vs vertical ramus osteotomy [VRO]) and changes in condylar volume and position.

Multimodality imaging in cardiogenic shock: state-of-the art.

Purpose Of Review: There is emerging evidence on the role of the multimodality imaging in the setting of cardiogenic shock. The utility of different imaging modalities, along with their pitfalls and limitations, and their integration in a multiparametric approach are discussed in the current review.

Recent Findings: The evaluation of congestion and perfusion in patients with shock has allowed a better understanding of the underlying physiopathological mechanisms.

Does implant placement using a minimally invasive technique increase early failures among trainees at an academic center?

Purpose: This study aims to identify whether dental implants placed using a flapless technique have a higher early failure rate, defined as failure within 6 months of placement, compared to implants placed with flap elevation when a surgical guide is not used.

Methods: A retrospective cohort study was conducted to evaluate implants placed with either flapless (FL) or mucoperiosteal flap (MF) surgery between 2006 and 2012 at the Philadelphia VA Medical Center (PVAMC). Implant status after FL or MF surgery was assessed using dental encounter and radiographs at subsequent follow-up appointments to assess for early implant failures within 6 months of implant placement.

What Are the Predictors of Craniomaxillofacial Injuries From Hoverboard Accidents?

Purpose: A hoverboard, or self-balancing scooter, is a battery-powered vehicle with 2 wheels connected by a longboard that requires handsfree operation. The purpose of the present study was to characterize the emergency department visits for hoverboard-related craniomaxillofacial trauma and determine predictors of injuries and hospital admission.

Materials And Methods: We performed a retrospective cohort study of the National Electronic Injury Surveillance System from 2015 to 2018.

Which Factors Affect the Completion and Publication of Dental Implant Trials?

Purpose: Clinical decision making in implant dentistry may be vulnerable to industry influence. The purpose of this study was to identify factors associated with the completion and publication of implant trials.

Materials And Methods: This was a cross-sectional study of dental implant trials registered with ClinicalTrials.

Are Motorized Scooters Associated With More Severe Craniomaxillofacial Injuries?

Purpose: The purpose of the present study was to compare the severity of craniomaxillofacial injuries between accidents involving motorized and nonmotorized standup scooters.

Materials And Methods: This is a 20-year cross-sectional study of the National Electronic Injury Surveillance System. Injuries from powered and unpowered standup scooters were included in this study if they involved the head, face, eyeball, mouth, or ear.

Lyme disease: diagnostic issues and controversies.

The diagnosis of Lyme disease is a controversial topic. Most practitioners and scientists recognize that Lyme disease is associated with certain objective clinical manifestations supported by laboratory evidence of infection with Borrelia burgdorferi sensu lato (the etiologic agent). There are others, however, who believe that patients with Lyme disease may have a wide variety of entirely nonspecific symptoms without any objective clinical manifestation and that laboratory evidence of infection by B.

Fluorodeoxyglucose positron emission tomography with computed tomography detects greater metabolic changes that are not represented by plain radiography for patients with osteonecrosis of the jaw.

Purpose: Imaging is important to identify subclinical changes and for treatment planning in patients with osteonecrosis of the jaw (ONJ) exposed to antiresorptive therapy. The aim of this study was to compare the findings at radiography with those at fluorodeoxyglucose (FDG) positron emission tomography (PET) with computed tomography (CT) for patients with ONJ related to antiresorptive therapy.

Materials And Methods: A cross-sectional retrospective analysis of patients with clinically identified ONJ lesions of the mandible was performed.
