Dental Prosthesis Failure, Edentulous Mouth
Conditions
Brief summary
This retrospective study investigates the longevity of dentures with SR Phonares II teeth after a wearing period of more than 10 years. The primary objective is to assess the survival rate of dentures with SR Phonares II teeth after more than 10 years. The secondary objectives asses the quality of the dentures concerning aesthetic, functional and biological properties.
Interventions
DEVICEExamination of dentures with SR Phonares II teeth
The intraoral situation will be examined similar to a standard dental examination. The dentures are then removed, cleaned and examined extraoral. Pictures and an impression of the dentures are taken.

| Survival Rate of Dentures With SR Phonares II Teeth | 10 years | After a wearing time of 10 years dentures with SR Phonares II teeth were examined by a dentist |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Quality of the Dentures Concerning Aesthetic, Functional and Biological Properties | 10 years | After a wearing time of 10 years dentures with SR Phonares II teeth were evaluated by a dentist according to adopted FDI criteria. Aesthetic properties (surface luster, surface staining, plaque accumulation, color match (to a reference), functional properties (fracture of material, marginal adaption, occlusal contour and wear, patient's view (evaluated during discussion) and biological properties (adjacent mucosa, oral health) were eveluated according the following FDI grades: * FDI grade 1: clinically excellent * FDI grade 2: clinically good * FDI grade 3: clinically satisfactory * FDI grade 4: clinically unsatisfactory |

Secondary
Quality of the Dentures Concerning Aesthetic, Functional and Biological Properties
After a wearing time of 10 years dentures with SR Phonares II teeth were evaluated by a dentist according to adopted FDI criteria. Aesthetic properties (surface luster, surface staining, plaque accumulation, color match (to a reference), functional properties (fracture of material, marginal adaption, occlusal contour and wear, patient's view (evaluated during discussion) and biological properties (adjacent mucosa, oral health) were eveluated according the following FDI grades: * FDI grade 1: clinically excellent * FDI grade 2: clinically good * FDI grade 3: clinically satisfactory * FDI grade 4: clinically unsatisfactory
Time frame: 10 years
Population: As only the denture was made available for some examinations in the clinical investigation, it was not possible to examine the oral health of these patients.
