Deformation of implant abutments after framework connection using strain gauges.

When a cylinder is connected to an abutment it is expected that abutment and cylinder will be subjected to compression forces throughout their periphery because of the clamping force exerted by the screw. The deformation resultant of this compression should be measurable and uniform along the periphery of the abutment. Considering that multiple retainers connected to each other can affect the fit of a framework, as well as the use of different alloys, it is expected that the abutments will present different levels of deformation as a result of framework connection.

[The impact on life quality due to oral conditions in people fifty years or above].

The objective of this work was to evaluate the influence of socio-demographic variables and oral health conditions in the quality of life of non-institutionalized people aged 50 or above, living in Bauru, São Paulo State. Clinical oral examinations were conducted on a sample of 224 people including dental caries, periodontal disease and usage or need of dental prosthesis according to WHO suggestions for community dental health surveys. They were also asked to answer a questionnaire comprised of 49 questions about the impact of their oral status on the activities of daily living (OHIP).
