Objectives: Clinical data on the performance of double-crown-retained removable dental prostheses (dcRDPs), especially beyond university studies, are rare. The objective of this retrospective clinical study was to evaluate the survival and complication-freeness probabilities of dcRDPs and to identify risk factors for failure and complications in a dental practice setting.
Materials And Methods: Anonymized practice data of 174 patients (56.
The rehabilitation of free-end situations is a frequent indication in prosthetic dentistry. Cantilever fixed dental prostheses (cFDPs) made of 1st and 2nd generation zirconia are one treatment option. Due to a unique gradient technology, combinations of different zirconium dioxide generations are thus feasible in one restoration.

The aim of this study was, therefore, to evaluate the reliability and validity of the German version of the OIDP in patients of a private practice.
Material And Methods: Translation of the original OIDP version was performed by a forward-backward process.
Objectives: To investigate the impact of the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) pandemic on stress and anxiety of preclinical and clinical dental students.
Materials And Methods: Dental students (participants) in their clinical course (CC; = 64) or preclinical course (PCC; = 53) were included in the study. The subjective perceived levels of stress and anxiety were evaluated using the Dental Environment Stress (DES) questionnaire and the Depression, Anxiety and Stress Scales (DASS) questionnaire.
Aims: To develop a German version of the Dental Environment Stress (DES) questionnaire, and to evaluate its reliability and validity.
Methods: The original English DES questionnaire was translated into German using a forward-backward translation process. To evaluate construct stability, a subgroup of dental students (n = 43) completed the DES twice (interval: 1 week).
Objectives: To investigate the long-term performance, over a period of up to 11 years, of tooth-implant-supported and solely implant-supported double-crown-retained overdentures (DCRDs) for complete restoration of the jaw.
Materials And Methods: Between 2002 and 2015, patients were consecutively enrolled in the study at Heidelberg University Hospital's Department of Prosthodontics. Scheduled and unscheduled visits were both documented on standardized forms.
Objectives: To determine implant survival and success of four conventionally but initially asynchronously loaded implants in implant-supported overdentures for the edentulous maxilla, in participants with opposing mandibular two-implant overdentures.
Material And Methods: Twenty-six participants received four implants in the region of the maxillary canines and molars. After healing, 24 of these participants (mean age: 68.
Objective: To evaluate how changes in oral health and chewing efficiency affect the changes in oral-health-related quality of life (OHRQoL) of nursing-home residents over six months.
Methods: The study was conducted in nine nursing homes. Sociodemographic and general data were collected for all eligible individuals (n = 150).
In the past few years the oral health of seniors has improved and more seniors retain their natural teeth until old age; however, the prevalence of oral diseases among seniors is still very high and a serious problem. Good oral health is, however, relevant for seniors as it influences the chewing function, the nutritional status and general satisfaction. In addition, diseases of the oral cavity show interactions with general health.

Methods: Thirty acrylic typodont teeth with root canals (10 each of tooth numbers 11, 14, and 17) were randomly allocated to a study or control group (15 teeth per group). In the study group, teeth were fixed in acrylic resin and subsequently digitized using a laboratory scanner.
Objective: The aim of this study was to evaluate the effects of dental status and chewing efficiency on the oral-health-related quality of life (OHRQoL) of nursing-home residents.
Materials And Methods: The study was conducted in nine nursing homes. All eligible participants were included, and general and medical data, information about nutritional status and their dental and prosthetic status were collected.
Background: There is limited information available about the oral and denture hygiene and oral health of nursing-home residents with cognitive and motor impairments.
Aims: The purpose of this study was to identify factors influencing the oral and denture hygiene and oral health of nursing-home residents with cognitive and motor impairments.
Methods: The study was performed in nine nursing-homes in Germany.
Purpose: The purpose of this study was to identify how changes to general health might affect the oral health of nursing-home residents over a six-month period.
Materials And Methods: The study was conducted in nine nursing homes in Germany. Sociodemographic and general data were collected at baseline and after six months.
Objectives: To evaluate the reliability and accuracy of spectrophotometric shade determination of premolars and to compare the results with those for incisors.
Material And Methods: Fifty-seven participants with natural maxillary incisors and premolars were recruited to investigate the research question. The colour of test teeth (incisors, n = 210; premolars, n = 192) was measured by use of the Vita Easyshade Advance (ES-A) and Vita Easyshade V (ES-V).
Purpose: To assess the extent of differences between the oral health of people aged 50 and 70 years in a community-based setting.
Materials And Methods: This research is part of the Interdisciplinary Study on Adult Development (ILSE). All participants lived in the city of Heidelberg, Germany.
Background: The oral health of seniors in nursing homes is compromised. Furthermore, reduced chewing efficiency is described to be associated with reduced cognition. However, studies investigating how prosthetic status affects the chewing efficiency of nursing home residents are not available.
