Implant Placement and Immediate Provisionalization After Alveolar Ridge Reconstruction in the Aesthetic Zone Using a Digital Workflow: A 1‐Year Prospective Case Series Study

Clinical Oral Implants Research, EarlyView.
ABSTRACT Introduction In single‐tooth replacement in the aesthetic zone, extensive bone defects require alveolar ridge reconstruction. A digital workflow involving CBCT and intraoral optical scanning enables a three‐dimensional assessment, prosthetically driven implant positioning, computer‐assisted implant surgery, and prefabrication of a temporary ...

Prevalence and Risk Indicators of Peri‐Implant Diseases in China: A Multicenter Cross‐Sectional Study

Clinical Oral Implants Research, EarlyView.
ABSTRACT Aim To evaluate the prevalence and risk indicators of peri‐implant diseases in a randomly selected Chinese population. Materials and Methods A total of 819 patients with 1412 implants from eight university hospital databases were clinically and radiographically evaluated along with medical records to assess the prevalence of peri‐implant ...

Emergence Profile Angle Matters—Restoring Peri‐Implant Health by Adjusting Prosthetics—A Narrative Review

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To review the biological and clinical relevance of prosthetic design, specifically the emergence profile and restorative angle in influencing peri‐implant tissue health, and to illustrate how biologically driven prosthetic modifications can resolve inflammation and support peri‐implant stability.

Soft‐tissue volume augmentation during early, delayed, and late dental implant therapy: A systematic review and meta‐analysis on professionally determined esthetics and self‐reported patient satisfaction on esthetics

Periodontology 2000, EarlyView.
Abstract The objective of the study was to assess the effect of soft‐tissue volume augmentation during early, delayed, and late dental implant therapy in terms of professionally determined esthetics and self‐reported patient satisfaction on esthetics. For this, a comprehensive electronic literature search was performed to identify randomized clinical ...

Three‐dimensional digital quantitative analysis of periodontal and peri‐implant phenotype—A narrative review

Periodontology 2000, EarlyView.
Abstract 3D digital evaluation of the periodontal and peri‐implant tissue, including CBCT, intraoral scanning, optical surface scanning, and ultrasonography, is being used in the clinical arena with increasing frequency. Thus, to validate the utilization of 3D digital analysis for this purpose, a critical evaluation of the reliability of digital ...

Acute intermittent hypercapnic hypoxia augments left ventricular contractility

The Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...

Sensitivity of zenith total delay accuracy to GPS orbit errors and implications for near‐real‐time GPS meteorology [PDF]

Journal of Geophysical Research: Atmospheres, 2002
Global Positioning System (GPS) measurements have been demonstrated to provide precipitable water vapor (PWV) estimates with a level of accuracy that is comparable to that of radiosondes and microwave radiometers. GPS measurements therefore have the potential to become a significant source of data for operational weather forecasting, provided that PWV (
