The application of positron annihilation spectroscopy for the studies of defects produced by different types of charged particles and ions in a variety of materials is discussed with specific examples. The ability to detect and quantify the information th... see more

Titanium nitride and/or nitrogen ion implanted coated dental materials have been investigated since the mid-1980s and considered in various applications in dentistry such as implants, abutments, orthodontic wires, endodontic files, periodontal/oral hygien... see more

The creation of new non-toxic materials that combines high osteointegration and strength characteristics is an urgent contemporary challenge. The use of complex oxides, such as lanthanum zirconate (La2Zr2O7), as non-reservable alloplastic implant material... see more

Ion beam sources for material processing in their working are no different from those required for space thrusters, ion implanters or for fusion experiments. They are scaled down versions of the devices earlier developed for space research. However, they ... see more

Objectives: Fracture strength is an important factor influencing the clinical long-term success of implant-supported prostheses especially in high stress situations like excessive crown height space (CHS). The purpose of this study was to compare the frac... see more

Objectives: Following tooth extraction, soft and hard tissue alterations occur; Different factors can affect this process. The objective of this study was to determine the effect of gap filling on buccal alveolar crestal bone level after immediate implant... see more

Objectives: The aim of this study was to compare the accuracy of dental implant impressions obtained by a combination of different impression techniques and viscosities of polyvinyl siloxane (PVS).Materials and Methods: Four parallel fixtures were placed ... see more

Introducción: La artroplastía cervical es una cirugía que implica el uso de implantes discales con la capacidad de conservar el movimiento del segmento. Constituye un reto para paises como el nuestro desarrollar alternativas a los altos costos d... see more

This study regarding the fundamental research in silicone materials field used by facial prosthesis and implanto- prosthetic therapy. The aim of the study is concerned with the synthesis and analysis of a new siliconic material with various excess materia... see more
