Geopolymer Composites-In Environmentally Friendly Aspects.

In the present work, a new, low energy consumption sol-gel synthesis route has been developed for geopolymer composites. Instead of the typically published 0.1-1.

Hierarchical Porous SiO Cryogel via Sol-Gel Process.

The aim of this research work was to develop a new, low-cost and low-energy-consuming preparation route for highly porous silica systems. The precursor gel systems were synthesized by sol-gel chemistry. The starting materials were TEOS and water glass in the sol-gel syntheses.

Midfacial Advancement Line-A Comparative Evaluation of a New Measurement Method in Orthognathic Surgery.

Purpose: In planning intraoral quadrangular Le Fort II osteotomy (IQLFIIO), simulation of hard and soft tissue changes will be important at the infraorbital, Le Fort I, and incisor level. The aim of our study was to evaluate a new method for visualization and quantification.

Materials And Methods: Three different methods of quantification were compared: the point-to-point (PTP) measurement, which has been viewed as the reference standard; part comparison analysis (PCA); and a new method, the midfacial advancement line (MFAL) measurement.

Perception of aesthetics and personality traits in orthognathic surgery patients: A comparison of still and moving images.

It is common in practicing orthognathic surgery to evaluate faces with retruded or protruded chins (dysgnathic faces) using photographs. Because motion may alter how the face is perceived, we investigated the perception of faces presented via photographs and videos. Two hundred naïve raters (lay persons, without maxillo facial surgery background) evaluated 12 subjects with varying chin anatomy [so-called skeletal Class I (normal chin), Class II (retruded chin), and Class III (protruded chin)].

Facial esthetics and the assignment of personality traits before and after orthognathic surgery rated on video clips.

Typically, before and after surgical correction faces are assessed on still images by surgeons, orthodontists, the patients, and family members. We hypothesized that judgment of faces in motion and by naïve raters may closer reflect the impact on patients' real life, and the treatment impact on e.g.
