Implementation and Evaluation of a Dynamic Neck Brace Rehabilitation Device Prototype.

Rehabilitation assistive devices for head/neck pain treatment cannot allow dynamic changes in position and orientation of the head/neck. Moreover, such devices can neither be used simultaneously nor can they assess the patients' head/neck conditions. This paper aims at designing and implementing a novel dynamic head/neck brace that provides static and dynamic support and/or traction at symmetric and asymmetric positions.

A systematic review of screw- versus cement-retained implant-supported fixed restorations.

Purpose: To systematically evaluate the survival and success of screw- versus cement-retained implant crowns.

Materials And Methods: The authors performed an electronic search of nine databases using identical MeSH phrases. Systematic evaluation and data extraction of the articles from 1966 through 2007 were completed by three reviewers and two clinical academicians.

Clinician- and patient-reported long-term evaluation of screw- and cement-retained implant restorations: a 5-year prospective study.

The purpose of this study was to evaluate the survival and success of screw- versus cement-retained implant crowns over a 5-year period. This was a multi-center prospective cohort study, consisting of patients who had ≥1 dental implant placed and restored in the anterior maxilla over a 5-year period. The primary predictor variable was the type of restoration (screw- versus cement-retained).
