Virtual planning, guided surgery, and digital prosthodontics in the treatment of extended mandible chondrosarcoma.

Chondrosarcoma is among the most common primary bone tumors in adults. In the mandible, chondrosarcoma is a very uncommon malignant cartilage-producing tumor. This case report shows how virtual planning combined with other digital technologies may improve masticatory function rehabilitation in patients with enlarged mandibular chondrosarcoma.

Influence of Kennedy class and number of implants on the accuracy of dynamic implant navigation: An in vitro study using an X-ray free evaluation methodology.

Objectives: The aim of this in vitro study was to evaluate the accuracy of fully guided dynamic implant navigation surgery in Kennedy I, II, and III class dental arch defects with two different implant designs, using an X-ray free evaluation method.

Methods: Polyurethane resin maxillary models simulated posterior edentulous defects. Four cone beam computed tomography (CBCT) scans and four intraoral (IOS) scans were obtained for each model and a digital wax-up with the correct implant positions was made.

Importance of education on infection control and on the hand skin health of dental personnel.

Background: Hand hygiene plays a significant role in infection control, yet it is performed correctly only 40% of the time. The daily use of soap, disinfectants and gloves can also affect hand skin health. Periodical educational interventions regarding hand hygiene can improve infection control.

Model-free digital workflow and immediate functional loading of implant-supported monolithic glass-ceramic crowns: A case series.

Objectives: The aim of this study was to evaluate surgical and prosthetic outcomes of immediate functional loading of implants with glass-ceramic screw-retained single crowns.

Methods: A total of 22 implants were placed. Within 24 h, functional full-contour glass ceramic crowns were delivered to patients.

Dental pulp stem cell-derived extracellular matrix: autologous tool boosting bone regeneration.

Background Aims: To facilitate artificial bone construct integration into a patient's body, scaffolds are enriched with different biologically active molecules. Among various scaffold decoration techniques, coating surfaces with cell-derived extracellular matrix (ECM) is a rapidly growing field of research. In this study, for the first time, this technology was applied using primary dental pulp stem cells (DPSCs) and tested for use in artificial bone tissue construction.
