Seismic Analysis for Design or Retrofit of Gravity Bridge Abutments

, 1997
Depending on their seismic resistance, existing bridge abutments may be vulnerable to earthquakes. Seismic resistance may be quantified in terms of a threshold acceleration level beyond which permanent deformation will occur.

Implant therapy in older patients: Prosthetic considerations and biomechanical implications for frailty/aging

Periodontology 2000, EarlyView.
Abstract Background Population aging is reshaping prosthodontic care for both partially and completely edentulous individuals. In older adults, conditions such as frailty, comorbidities, polypharmacy, and cognitive decline can have a direct impact on the biological and biomechanical demands of implant therapy, thereby influencing the success of implant

Three‐Dimensional Analytical Model of a Free‐Standing Square Rocking Column

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 8, Page 1710-1727, 10 July 2026.
ABSTRACT A three‐dimensional analytical two‐degree‐of‐freedom (2DOF) model is developed to describe the bounded rocking response of free‐standing rigid square columns subjected to bidirectional seismic excitation. The formulation extends Housner's classical planar theory by deriving the full three‐dimensional equations of motion for a column ...

Dental Implants in Adults With Intellectual Disabilities: A Multicenter Retrospective Study. Part 1: Implant Outcomes

Journal of Oral Rehabilitation, Volume 53, Issue 7, Page 1259-1274, July 2026.
This multicenter retrospective study evaluated implant survival and peri‐implant health in adults with non‐syndromic intellectual disability. Among 453 implants with long‐term follow‐up, survival exceeded 92%, with tissue‐level implants and cement‐retained restorations associated with healthier peri‐implant conditions. These findings support the use of

Critical Acceleration Levels for Free Standing Bridge Abutments

, 1995
An analytic procedure for predicting threshold accelerations for movement of gravity wall bridge abutments due to earthquake loading is described. The method draws on previous work related to the sliding mode of failure, and a newly developed theory on ...

Treatments of unesthetic amalgam tattoo: A literature review and a case report

Clinical Advances in Periodontics, Volume 16, Issue 2, Page 365-373, June 2026.
Abstract Background An amalgam tattoo is an iatrogenic lesion that can lead to esthetic concerns. This paper presents a literature review aimed at exploring treatment options available to clinicians for addressing this unesthetic issue. Methods The initial search identified 209 potentially relevant publications.

A rare mental foramen variation and the role of cone‐beam computed tomography in preventing nerve injury: A case report

Clinical Advances in Periodontics, Volume 16, Issue 2, Page 374-380, June 2026.
Abstract Background The interforaminal space is frequently used for dental implant placement due to its strategic location between the bilateral mental foramina. However, neurosensory disturbances following surgical intervention near the mental foramen (MF) can occur in up to 43% of cases.

Monitoring of a bridge with integral abutments [Elektronisk resurs]

, 2009
Preliminary results obtained from short term test-loading are used to illustrate possibilities of FEM used to calibrate complex interaction characteristics between a pile and soil in a bridge with integral abutments.

Aging, Dauer, and Stature Phenotypes Are Conferred by Structure‐Directed Missense Mutations in the Endogenous AGE‐1/Phosphatidylinositol 3‐Kinase Catalytic Subunit

Aging Cell, Volume 25, Issue 6, June 2026.
Structure‐guided missense mutations in the C. elegans AGE‐1/PI3Kinase catalytic subunit and its LET‐60/Ras‐binding interface reveal separable signaling outputs from the Ras‐bound PI3K complex. Enhanced canonical catalytic activity, conferred by a gain‐of‐function mutation modeled on oncogenic human p110⍺ PI3K variants, promotes aging, reproductive ...
