Dental Student Perceptions of Distance Education over Time: A Mixed-Methods Study.

Objectives: Amid the COVID-19 pandemic, the transition to distance learning raised pertinent questions regarding advantages and challenges compared to traditional in-person learning. This study aimed to investigate dental students' perceptions of distance learning throughout the pandemic, examining its impact on their education.

Methods: This study employed a convergent mixed-methods design.

Volumetric assessment of changes in the alveolar ridge dimension following guided bone regeneration using a combination freeze-dried bone allograft with collagen membrane or novel resorbable scaffold: A prospective two-center clinical trial.

Background: The aim of this study was to examine osseous changes following lateral bone augmentation using a novel scaffold (OV) alone and compare it to combination therapy using freeze-dried bone allograft (FDBA) and resorbable collagen membrane (FDBA/CM).

Methods: Thirty patients completed this 9-months prospective two-center cohort clinical trial. Before surgery and 9-months re-entry, linear measurements were performed, and impressions taken.
