Conservative Surgical Approach to Restore Necrotic Columella in Patients Undergoing Neonatal Usage of Nasogastric Tube.

Context: A common complication, related to the use of nasogastric tube during the 1 day of life, is the necrosis of the columella. Esthetic damage in the early age typically leads to a healing request with very high result expectations.

Aims: We aimed to develop and use an innovative surgical technique.

Metals used in maxillofacial surgery.

The goal of maxillofacial surgery is to restore the shape and functionality of maxillofacial region. In the past years, there has been a tremendous progress in this field because of significant advances in biotechnology that provided innovative biomaterials to efficiently reconstruct the maxillofacial injured region. By using appropriate selection of the implant biomaterial, it is possible to reconstruct the native tissue, both in form and function.

Biomechanical behaviour of a jawbone loaded with a prosthetic system supported by monophasic and biphasic implants.

Modern implantology is based on the use of endosseous dental implants and on the study of osseointegration processes. The loss of marginal bone around a dental implant can be caused by many factors; the proper distribution of the masticatory loads is important and is closely dependent on the quality and quantity of bone tissue surrounding the implant. In fact, bone has the ability to adapt its microstructure, through processes of resorption and neoformation of new bone matrix, as a result of the mechanical stimuli that are generated during the chewing cycles.

Retrospective Analysis of the Correlation Between the Facial Biotype and the Inclination of the Upper Canine Cusp Axis to the Occlusal Plane.

Permanent maxillary canines are the second most frequently impacted teeth and the prevalence of this clinical condition is estimated to be 1-2% in the general population. The diagnosis of maxillary canine impaction should be based on both clinical and radiographic examinations. The aim of this study was to evaluate the presence of a correlation between the facial biotype and the inclination of the upper cusp axis.
