Objectives: To classify the complete-arch implant scanning techniques recorded by using intraoral scanners (IOSs).
Overview: Different implant scanning techniques have been described for recording complete-arch implant scans by using IOSs. However, dental literature lacks on a classification of these implant scanning techniques. Implant scanning techniques aim is to record the 3-dimensional position of the implants being scanned, while implant scanning workflows require additional scans to record all the information needed for designing an implant prosthesis. This additional information includes soft tissue information, tooth position, antagonist arch, and maxillomandibular relationship.
Conclusions: There are five complete-arch implant scanning techniques captured by using IOSs: non-splinting, non-calibrated splinting, calibrated implant scan bodies, calibrated frameworks, and reverse impression methods. The digital workflow varies depending on the implant scanning technique selected.
Clinical Significance: The understanding of the varying implant scanning techniques and the main differences among them may ease the decision criteria for recording digital implant scans by using intraoral scanners.

Effect of a metal artifact reduction algorithm on cone-beam computed tomography scans of titanium and zirconia implants within and outside the field of view.

Department of Neurosciences, Reproductive and Odontostomatological Sciences, University of Naples Federico II, Naples, Italy.
Purpose: This study aimed to evaluate the impact of a metal artifact reduction (MAR) algorithm on cone-beam computed tomography (CBCT) scans of titanium and zirconia implants, both within and outside the field of view (FOV).
Materials And Methods: In this study, a dry human mandible was positioned in a CBCT scanner with only its left quadrant included in the FOV. Each type of implant (titanium and zirconia) was placed once in the right second premolar extraction socket and once in the left second premolar extraction socket of the mandible.
Vestibular Implant Surgery: How to Deal With Obstructed Semicircular Canals-A Diagnostic and Surgical Guide.
J Otolaryngol Head Neck Surg
January 2025
Division of Otorhinolaryngology-Head and Neck Surgery, Department of Clinical Neurosciences, Geneva University Hospitals, University of Geneva, Geneva, Switzerland.
Background: A vestibular implant can partially restore vestibular function by providing motion information through implanted electrodes. During vestibular implantation, various obstructions of the semicircular canals, such as protein deposits, fibrosis, and ossification, can be encountered. The objective was to explore the relationship between preoperative imaging and intraoperative findings of semicircular canal obstruction and to develop surgical strategies for dealing with obstructions of the semicircular canal(s) in patients eligible for vestibular implantation.

Background: Hemorrhage is a dangerous complication of deep brain stimulation (DBS) surgery, but a comprehensive explanation of the associated risk factors remains inconclusive, particularly application of microelectrode recording (MER) compared to macrostimulation (non-MER) based DBS procedures. We conducted a comparative analysis of MER and macrostimulation techniques, evaluating the impact of brain penetrations by microelectrode guiding cannulas on the occurrence of intracranial hemorrhagic events.
Methods: This retrospective study included all DBS procedures (MER-based and non-MER based) performed at a single medical center from November 2008 to June 2023.
Longitudinal volumetric analysis of compartments in chicken eggs using ultra-high-field magnetic resonance imaging.

Department of Ophthalmology, Rostock University Medical Center, Rostock, Germany.
Introduction: The chicken egg, with its compartments, is a widely used and popular animal model in experimental studies. This study aimed to quantify the volumes of the yolk/yolk sac, amniotic fluid, and chicken embryo using non-invasive ultra-high-field magnetic resonance imaging (UHF-MRI).
Materials And Methods: In total, 64 chicken eggs were examined using a 7 T UHF-MRI scanner, acquiring T2-weighted anatomical images of the entire egg from developmental day 1 to 16 (D1-D16).
Electrophoretic Deposition of Gentamicin Into Titania Nanotubes Prevents Evidence of Infection in a Mouse Model of Periprosthetic Joint Infection.

Periprosthetic joint infection (PJI) is a leading cause and major complication of joint replacement failure. As opposed to standard-of-care systemic antibiotic prophylaxis for PJI, we developed and tested titanium femoral intramedullary implants with titania nanotubes (TNTs) coated with the antibiotic gentamicin and slow-release agent chitosan through electrophoretic deposition (EPD) in a mouse model of PJI. We hypothesized that these implants would enable local gentamicin delivery to the implant surface and surgical site, effectively preventing bacterial colonization.
