Pre-implant surgery complexity for achieving implant-supported prosthetic rehabilitation in oligodontia patients: a retrospective study.

Introduction: Oligodontia is a rare dental developmental pathology that requires prolonged, complex and multidisciplinary treatment. Although bone augmentation is frequently required during a complete implant treatment of oligodontia. Therefore, we evaluated the ability to predict pre-implant surgery complexity based on age, number of missing teeth, and number of implants required to achieve implant-supported prosthetic rehabilitation.

Augmented reality in implantology: Virtual surgical checklist and augmented implant placement.

Objectives: Aim of the present study was to create a pedagogical checklist for implant surgical protocol with an augmented reality (AR) guided freehand surgery to inexperienced surgeons using a head mounted display (HMD) with tracking.

Methods: The anatomical model of a patient with two missing mandibular teeth requiring conventional single-tooth implants was selected. The computed tomography (CT) scans were extracted and imported into segmentation and implant planning software.

System Mapping of the Production and Value Chain to Explore Beekeeping Potential in Southwest Ethiopia.

Ethiopia has a high potential for the production of honey and other apiary products due to its ideal agroecology. This potential is, however, not yet well utilized due to weak production and valorization systems. The study analyzed beekeeping systems and their honey value chain to detect the barriers and to explore ways to better exploit the existing potential.

Primary Failure of Dental Eruption Due to Variants Parathyroid Hormone Receptor 1: Retrospective Study and Proposal of Guidelines Treatment.

Objective: Primary failure of eruption is characterized by a nonsyndromic defect in tooth eruption in the absence of mechanical obstruction. It is correlated to rare heterozygous variants in the parathyroid hormone receptor 1 gene. The management of primary failure of eruption is complex because many therapies are ineffective.
