• Abstract

  The objective of this study is to evaluate the histological response of perimplant bone tissue contact with two different surfaces of dental implants placed in bone defects filled or not with biomaterial. Ninety-two titanium implants will be divided into four groups according to the type of surface treatment and the presence of biomaterial in the implant site: (G1) porous-hydrophilic surf…

• Abstract

  There several studies concerning osteosynthesis of mandibular angle fractures with conventional straight or curved plates. However, few studies deal with grid plates. The geometry of such plates allows to use increased number of screws, three-dimensional stability, torque resistance, malleability and low-profile. This study will evaluate the use of grid plates for internal stable fixatio…

• Abstract

  The objective of this study will be to compare, through histomorphometric analysis, the tissue repair of wounds on the back of rats produced by incisions with different types of instruments (conventional blade, electrocautery - knife tip, Colorado tip and Thin-Cut type) at different periods of the healing process. For this purpose, 30 male rats (Rattus norvergicus albinus, Holtzman variet…

• Abstract

  Among surgical protocols for the repair/reconstruction of critical-size bone defects, the use of bone grafting or biocompatible materials are indicated for these cases. However, the presence of alloplastic materials may in some way positively or negatively affect the repair process into respective host. The aim of this study is to evaluate, by histologic, immunohistochemistry, and imaging…

• Abstract

  The extensive bone defect or critical defect has been widely studied in recent decades, especially when we think about implant rehabilitation. The main procedure to restore a local architecture is Guided Bone Regeneration (GBR). Among various materials used in procedure, absorbable membranes have fundamental importance to avoid undesirable tissues formation in defects area. The aim of thi…

• Abstract

  Orbital fractures are highly prevalent and represent 40% of all midface fractures. Their treatment is challenging due to the difficulty of anatomic reconstruction. They can be isolated or associated with other facial fractures, resulting in bone defects with a variety of locations, sizes and severity. Those orbital wall defects create changes in the orbital volume and anatomy and result i…
