Unlabelled: Accurate impressions provide a foundation for successful implant prosthodontics. This paper is aimed at the general dental practitioner (GDP) who would like to start restoring dental implants and demystifies the terminology, introduces the basic armamentarium and discusses the relative merits of different implant impression techniques. Detailed, step-by-step instructions for making impressions using the closed and open tray techniques are provided and the importance of verification jigs are highlighted.
Clinical Relevance: A successful restoration is dependent upon proper planning and meticulous clinical processes. An understanding of impression techniques is therefore fundamental for the GDP wishing to restore implant-supported prostheses.
Objectives: The reader should be familiar with different implant components and understand the impression techniques used in implant dentistry.

Purpose: This study aimed to compare different treatment modalities to correct ill-fitted maxillary complete denture either by the conventional relining method or by scanning the relining impression and digitally construct a new denture regarding patient satisfaction, denture retention, and adaptation.
Materials And Methods: Twelve edentulous patients suffering from loose maxillary complete dentures were selected, dentures' borders and fitting surfaces were prepared, and relining impressions were taken, the impressions were scanned and the STL files were used for CAD/CAM milling ( computer aided designing/ computer aided manufacturing) of new maxillary dentures (Group A), then the relining impression went through the conventional laboratory steps to fabricate (Group B) maxillary dentures. Both groups were evaluated regarding patient satisfaction by a specially designed questionnaire, retention values were measured by a digital force gauge at denture insertion appointment and two weeks later, geomagic software was used to evaluate dentures adaptation to oral tissues.

Background: Effective evidence-based physical activity and nutrition interventions to prevent overweight and obesity and support healthy child development need to be sustained within Early Childhood Education and Care (ECEC) services. Despite this, little is known about factors that influence sustainability of these programs in ECEC settings. Therefore, the aim of this study was to describe the factors related to sustainability of physical activity and nutrition interventions in ECEC settings and examine their association with ECEC service characteristics.

Latent fingerprints (LFPs) are invisible impressions that need to be developed before being used for criminal investigation; however, existing fingerprint visualization techniques face challenges, such as complex preparation and poor contrast. To advance practical fingerprint detection, green-emissive micron-sized curcumin/kaolin composites were synthesized a facile and cost-effective one-step physical cross-linking method, which exhibited unprecedented performance in developing diversified marks, including LFPs, knuckle prints, palm prints, and footprints, with clear three-level details on various substrates. Notably, the powders successfully developed LFPs that were aged for 30 days and even up to 100 days, meeting the stringent requirements for comprehensive forensic application.

Background: Due to the shortage of healthcare professionals with expertise in diagnosis and treatment of Alzheimer disease and related dementias, there are long wait times to be evaluated in dementia specialty clinics and no clear guidance about how to allocate limited resources. The purpose of this study was to examine utility of cognitive screening measures administered by clinic staff to determine level of cognitive impairment to aid in decisions about which patients may benefit from full diagnostic services.
Methods: Participants were 169 older adults who completed an intake interview, including a brief cognitive screening test, conducted by a neuropsychologist at a dementia specialty clinic.

Aim: The aim of this study was to compare the marginal accuracy of polyetheretherketone (PEEK) and zirconia copings fabricated using computer-aided design/computer-aided manufacturing (CAD/CAM) technology, and to assess the impact of their material properties on accuracy when produced with a 4-axis milling system under controlled conditions.
Settings And Design: The study employed an in vitro design with a stainless steel die model featuring a 6 mm axial wall height, a 6-degree total occlusal convergence, and a radial shoulder finish line.
Materials And Methods: Thirty stone dies were created from silicone impressions of the metal die and poured using type-IV dental stone.
