Periodontal treatment and peripheral arterial disease severity - a retrospective analysis of health insurance claims data.

: Although epidemiological data suggest an association between periodontitis (PD) and peripheral arterial disease (PAD), it is currently unclear whether treatment of PD influences the severity of PAD. : Whether periodontal treatment is associated with PAD disease severity was examined by analysing health insurance claims data of patients insured by the German health insurance fund, BARMER, between January 1, 2012 and December 31, 2016. The presence of PAD was determined in individuals using International Classification of Diseases (ICD) 10 revision codes for intermittent claudication (IC) or chronic limb threatening ischaemia (CLTI).

Stabilizing mandibular complete dentures by a single midline implant-influence on quality of life: 2-year results from a randomized clinical trial comparing different loading protocols.

The aim of this multicenter randomized controlled clinical trial was to assess the effect of stabilizing an existing complete denture, by means of a single mandibular implant, on HRQoL. Furthermore, the impact of the loading protocol, i.

Tooth loss after periodontal treatment-Mining an insurance database.

Objectives: The aim of this study was to evaluate tooth loss after periodontal treatment.

Methods: The data was collected from the digital database of a major German national health insurance company. Periodontal treatment was the intervention in the treatment group.

Clinical Fit of Monolithic Zirconia Single Crowns.

Purpose: To analyze the clinical fit of monolithic zirconia single crowns (MZSCs) in a prospective cohort study.

Materials And Methods: A total of 30 posterior teeth were restored with MZSCs. Silicone replicas were made to measure the clinical fit using a stereomicroscope.

The single mandibular implant study - Short-term effects of the loading protocol on Oral Health-related Quality of Life.
