Posted on 9 Ottobre 2018 by amminsitodelprof

1) To analyze how surface roughness and staining affect the mechanical strength of zirconia-based ceramic materials, which are used in combination with CAD/CAM technologies. 2) To compare the type of failure of eight commercially available ceramics for aesthetic coating of zirconia structures; 3)...

Osseoperception: a clinical study on 24 patients

Posted on 9 Ottobre 2018 by amminsitodelprof

Between 1950 and 1960, Branemark established that bone is a dynamic living tissue. The importance of nervous fibers accompanying the bone vessels was recognized only 10 years later. These fibers, among other things, release neuropeptides like CGRP and s(P), which orchestrate bone remodeling proce...

Split crest – a case report

Posted on 9 Ottobre 2018 by amminsitodelprof

The advances in oral surgery allowed us to compensate for the anatomical loss which arise from several diseases and cause negative clinical conditions to implant rehabilitation. Among pre-implant techniques there is the split crest: through expanders, it makes rehabilitation possible when the red...

Posted on 9 Ottobre 2018 by amminsitodelprof

The maxillary sinus, also called Higmoro antrum, is a cavity within the maxillary bone which joins the alveolar crest to form the outer wall, while the lower wall is normally contiguous with molars and first premolars, and its walls are covered by Schneiderian membrane. Initially, Scialom needles...

INTEGRAL CERAMICS – a case report

Posted on 9 Ottobre 2018 by amminsitodelprof

The continuous research for a good aesthetic, biological and functional integration of dental restorations has produced satisfying results in the field of ceramics. This material, without metallic structure, can transmit the light very similarly to natural teeth. The general term “integral cera...

Facets

Posted on 9 Ottobre 2018 by amminsitodelprof

Facets are the strong point of esthetic, less-invasive dentistry. They are extremely-thin prosthetic manufactures, such as Lumineers, which can be around 0,1 – 0,3mm thick and sacrifice little tissue of affected teeth. Therefore, they can soon solve those problems caused by dyschromia, fractures ...
