When implants are installed immediately after tooth extraction may occur anchoring primary decreased, delay or failure of osseointegration process. This occurs because of the large interface between the surrounding walls of the socket and the surface of the implant. For reconstruction, replacement or filling of bone defects the solution can be obtained with the use of autogenous, heterogenous or allogeneic bone grafts. However, these grafts suffer certain drawbacks, particularly a high rate of donor site morbidity, limited amounts of available bone, and the additional operative time required for harvest. For these reasons, intensive efforts have been directed toward developing alternative substances for to either augment or substitute. In this paper, we will examine some of the commonly used materials : fibrin and calcium phosphate.

The following is a clinical case report of a patient whose main complaint was the presence of a generalized spacing in the anterior maxillary segment. After meticulous clinical analysis and discussions of the clinical procedures to be adopted, a labial frenectomy was our first choice, so that we could reduce the diastemas directly using composite resin. It was observed that the association of clinical and restorative procedures was capable of giving back shape, function and dental aesthetics, allowing to the young patient the satisfaction of smiling without any fear.

Wood is a renewable material and has unique characteristics that stem from its orthotropic properties. The objective of this study was to develop and implement an informational Selection of Materials and Manufacturing Processes appropriate to the activity of Product Design - Woods. Composed of a Digital Information System, distributed, and an ordered collection of samples. The design of a product, carries with it the choice of material, and the choice of a manufacturing process. Information on materials and manufacturing processes are available with different content, media and interfaces. However, such information is not systematized so that they can be recovered, as the need for the designer, especially on wood. This set of methods is called the Selection of Materials and Manufacturing Processes. It is hoped through this study that the methodologies for SMPF are employed by product designers, architects and engineers in Brazil.
