TL;DR: It was suggested that the platform switching configuration has the biomechanical advantage of shifting the stress concentration area away from the cervical bone-implant interface and has the disadvantage of increasing stress in the abutments or abutment screw.

TL;DR: Declines in the number of residual teeth, occlusal force and salivary flow were associated with a reduction of masticatory performance in older adults, suggesting that tooth loss is not considered as an attribute of physiological ageing, then ageing by itself may not be a risk factor for masticatories dysfunction.

TL;DR: Within limitations of the model study, it was suggested that fixtures with internal-hex showed widely spread force distribution down to the fixture tip compared with external hex ones.

TL;DR: This study investigated the development of a computer-aided system for designing and fabricating removable complete dentures by obtaining anatomical and morphological information of edentulous residual ridges and surrounding tissues from maxillomandibular double impressions mounted on a high-speed, three-dimensional laser scanner.

TL;DR: Declines in occlusal contact, Occlusal force and salivary flow appear to be associated with reduction of masticatory performance in older adults, however, the crucial factors for masticatories performance varied, depending on the phase of occlical collapse.
