  • transfer information enhancement with a 2 d tactile stimulator array for acoustic vision Substitute System
    Annual International Conference of the IEEE Engineering in Medicine and Biology - Proceedings, 2006
    Co-Authors: Hirofumi Taki, Toru Sato
    Abstract:

    Existing vision Substitute Systems provide insufficient information as a navigation System. To present spatial information in detail, we propose a stimulation method for transfer information enhancement by using a 2-D tactile stimulator array. Stimulators are divided into several groups. Since each stimulator group is activated alternately, the interval of stimulators can be shortened to less than the two-point discrimination threshold. In the case that stimulators are divided into two and four groups, the number of stimulators increase to twice and four times of that in the case of the two-point discrimination threshold. We examine and confirm this method experimentally.

  • the effect of permanent grafting materials on the preservation of the buccal bone plate after tooth extraction an experimental study in the dog
    Clinical Oral Implants Research, 2012
    Co-Authors: Haitham Bashara, Johan Caspar Wohlfahrt, Ioannis Polyzois, Staale Petter Lyngstadaas, Stefan Renvert, Noel Claffey
    Abstract:

    Objectives: The aim of the present study was to evaluate the effects of a novel bone Substitute System (Natix®), consisting of porous titanium granules (PTG) and a bovine-derived xenograft (Bio-Oss®), on hard tissue remodelling following their placement into fresh extraction sockets in dogs. Material and methods: Six modalities were tested; Natix® granules with and without a covering double-layered Bio Gide® membrane; Bio-Oss® with and without a covering double-layered Bio Gide® membrane; and a socket left empty with and without a covering double-layered Bio Gide® membrane. Linear measurements, indicative of buccal bone height loss, and an area measurement indicative of buccal bulk bone loss were made. The statistical analysis was based on the Latin Square design with two blocking factors (dog and site). Tukey's post hoc test was used to adjust for multiple comparisons. Results: Histological observation revealed that while bone formed around both the xenograft and the titanium particles, bone was also noted within titanium granules. Of the five modalities of ridge preservation techniques used in this study, no one technique proved to be superior. Conclusion: The titanium granules were observed to have promising osseoconductive properties. To cite this article: Bashara H, Wohlfahrt JC, Polyzois I, Lyngstadaas SP, Renvert S, Claffey N.
