Comparative trueness of complete‐arch implant position acquisition using auxiliary geometric device–aided and noncalibrated scanbody–based intraoral scanning versus smartphone‐based and dedicated extraoral photogrammetry

Journal of Prosthodontics, EarlyView.
Abstract Purpose To compare the trueness of four techniques for complete‐arch implant position acquisition: intraoral implant scanning (IOIS) using auxiliary geometric devices (AGDs), IOIS using horizontally extended noncalibrated scanbodies (NCSBs), smartphone‐based extraoral photogrammetry (EPG), and EPG with a dedicated scanner, with the null ...

Finite element modelling and load share analysis for involute worm gears with localised tooth contact [PDF]

, 2001
A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Soft Tissue Substitutes: Current Biomaterials and Indications at Teeth and Implant Sites

Journal of Periodontal Research, EarlyView.
This manuscript provides an updated overview of the current evidence on soft tissue graft substitutes for teeth and dental implants. When appropriately indicated, these biomaterials offer a reliable, less invasive alternative to autogenous grafts, effectively improving root coverage, keratinized mucosa width, and soft tissue thickness with reduced ...

Localized Periodontitis in Young Individuals: Aggregatibacter JP2 Clone, Immunological Dysfunctions and Other Stories

Journal of Periodontal Research, EarlyView.
This review describes the features of grade C molar‐incisor pattern periodontitis and discusses the role of A. actinomycetemcomitans in its pathogenesis and why molars and incisors are preferably affected. Possible future studies on this aggressive disease in primary and permanent dentition and emerging omics techniques for diagnosis and management are

Tooth Loss and Edentulism Are Associated With Poorer Quality of Life: A Systematic Review and Meta‐Analyses

Journal of Periodontal Research, EarlyView.
Tooth loss compromising functional dentition doubles the odds of poor oral health‐related quality of life (OR 2.08), while complete tooth loss nearly quadruples them (OR 3.99). These findings from a systematic review of population‐based studies underscore tooth preservation as a critical public health priority.

Volume‐Stable Collagen Matrix With or Without Platelet‐Rich Fibrin Impregnation for Multiple Gingival Recessions: A Randomized Clinical Trial

Journal of Periodontal Research, EarlyView.
This split‐mouth randomized clinical trial showed that platelet‐rich fibrin impregnation of a volume‐stable collagen matrix did not improve clinical, esthetic, or patient‐reported outcomes compared with collagen matrix alone for multiple gingival recession treatment after 6 months. ABSTRACT Aim This split‐mouth randomized clinical trial aimed to assess

A Novel Method for the Fault Diagnosis of a Planetary Gearbox based on Residual Sidebands from Modulation Signal Bispectrum Analysis [PDF]

, 2014
This paper presents a novel method for the fault diagnosis of planetary gearboxes based on an accurate estimation of residual sidebands using a modulation signal bispectrum (MSB).

Periodontal Diseases as a Public Health Challenge: Rationale, Prevention, Equity, and Sustainable Care—A Global Call for Action

Journal of Periodontal Research, EarlyView.
Periodontal diseases affect over a billion people worldwide, yet remain weakly integrated into global non‐communicable disease agendas. We propose reorienting periodontal care around three public health opportunities—upstream prevention, diagnosis fit for both clinical and population use, and value‐based treatment—prioritizing prevention, value, and ...

Digital Implant Dentistry: The Past, the Present, the Future

Journal of Periodontal Research, EarlyView.
This narrative review examines the evolution of digital implant dentistry across the entire clinical workflow, comparing historical and contemporary approaches at each stage. Particular emphasis is placed on distinguishing truly disruptive innovations from more gradual technological advances, while also critically discussing emerging developments ...
