The implant-abutment connection of a two-piece dental implant depicts a complex micro-mechanical behavior: a micro-gap is evident at the implant-abutment interface, even in the virgin state. Its width varies when external mechanical load is applied. High resolution synchrotron-based radiography in combination with hard X-ray phase contrast to image this gap and estimate its size is deployed. Th...

Breast augmentation with implants is one of the most commonly performed plastic surgery procedures. The goal of the operation is to increase the size, shape or fullness of the breast. It is accomplished by placing silicone, saline or alternative composite breast implants under the chest muscles, fascia or the mammary gland. This type of operation is no exception concerning the occurrence of com...

Purpose: This study investigates the effect of two different attachment size in the single implant retained over denture on the muscle activity. Materials and Methods: Twenty completely edentulous patients were selected for the study with normal ridge size and divided into two groups. In all patients single implant was placed at the area of midline after cone beam taken. Three months later low ...

BACKGROUND Accumulating evidence suggests that alveolar crestal bone resorption occurs as a result of the microgap that is present between the implant-abutment interface in dental implants. The objective of this longitudinal radiographic study was to determine whether the size of the interface or the microgap between the implant and abutment influences the amount of crestal bone loss in unloade...

Fast and reliable methods for predicting and monitoring in-vivo bone strength are of great importance for hip joint replacement. To avoid adaptive remodeling with cortical thinning and increased porosity of the bone due to stress shielding, in a preoperative planning process the optimal implant design, size, and position has to be determined. This process involves interactive implant positionin...

Short stemmed hip endoprostheses represent a relevant alternative to standard sized total hip stems. Especially in terms of bone stock preservation and minimal invasiveness the reduced length of such implants is beneficial. However, the smaller implant size is linked to a reduced surface geometry and thereby bone-implant-interface to provide implant stability. In order to evaluate the interfaci...

The use of mini-implants have made a major contribution to orthodontic treatment. Demand has aroused scientific curiosity about implant placement procedures and techniques. However, the reasons for instability have not yet been made totally clear. The aim of this article is to establish a relationship between implant placement technique and mini-implant success rates by means of examining the f...
