    Notes: Purpose This study investigated the effects of various polymerization methods and of various types of silane coupling agents on the intefacial bond strengths of Molloplast-B and of two types of heat-processed polymethyl methacrylate (PMMA).Materials and Methods Standardized blocks of PMMA were processed and stored in 100% humidity for 14 days. Silicone of equal dimensions was flasked and processed with premixed and fresh-mixed silane coupling agents interposed. Processing utilized both a typical heated-water system and a dry-heat oven. Following recovery, the specimens were peel-tested at an angle of 180° in an Instron machine.Results There was no significant difference between the test variables of Lucitone (Dentsply/York Division, York, PA) versus Lucitone 199 (Dentsply/York Division), nor with wet versus dry heat polymerization methods. However, the mean bond strengths for premixed silane improved slightly in a wet polymerization environement. Conversely, fresh-mixed silane's mean bond strength increased slightly with dry-heat polymerization.Conclusions The bond strength between a methyl methacrylate denture base and a silicone soft liner varies only slightly when either Lucitone, Lucitone 199, or polymerization in a wet or dry environement is used. Under the conditions of this study, a fresh-mixed silane coupling agent produced a distinctly superior bond strength.

    Adapting a Dental Surveyor to Function in Two Planes (1993)

    Notes: Many bilateral distal extension removable partial dentures possess insufficient guidance to control their dislodgement. When such a situation is observed, the tips of retentive clasps must be located in both an occlusogingival and mesiodistal (away from the denture base area) undercut. The specific location can be identified with a dental surveyor that has been adapted to function in two planes. Details of the adaptation process and use of the surveyor are described.

    Retention for a Removable Partial Denture (1992)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of prosthodontics 1 (1992), S. 0 
    Details
    ISSN: 1532-849X
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: This article addresses the complex nature of retention in a removable partial denture. Retentive features range from magnets and springs to clips, clasps, and interfacial surface tension. The retentive quality of an extracoronal clasp varies with the alloy, physical form, location on the abutment, and positional relationship to other elements. Surveying to identify both occlusogingival and mesiodistal undercuts when the path of random dislodging forces are not definitely controlled is needed for effective retention. Augmentation of ineffective retention in existing clasps should concentrate on methods of deepening the undercut or increasing the suprabulge. Tightening of clasps already in contact with a tooth frequently produces adverse changes.

    Notes: [Auszug] Symbiotic systems are long-period binaries consisting of a cool giant primary and a hot secondary star. R Aquarii is a unique symbiotic system because it contains as a primary a Mira variable with a period of 387 days. From its variability a distance of 250 pc has been estimated4. Kinematic ...
