Abstract:

Purpose The McGill Consensus (2002) recommends two-implant over denture as the first choice for treatment for the edentulous mandible. There have been numerous methods described to aid the retention of complete lower dentures. Recently plastic low-profile attachments have become available for use with implant supported dentures. Other than their low profile they are advertised as being simpler to maintain and more economic than their ball and clip or O-ring counterparts. However, there appears to be a lack of data on the retentive forces these for these systems. Two over denture retaining systems the Locator and the Southern Implant-incorporating plastic retaining components were tested and compared. This in vitro study set out to measure the retentive forces created by the Southern Implant ball and clip and the Zest Anchor Locator press-stud. Each system tested offered several different strengths of attachment. Methodology: A custom built jig was used to hold the various components for each attachment system and mount the monacyclic testing machine. Thisenabledmeasurementofthe retentive forces created by each attachment system 3,000 cycles of insertion and removal in a simulated oral environment. Results: The retentive forces created by the Southern Implants plastic clips and Locator nylon inserts fell exponentially with the number of the test cycle. After 100 cycles, the retentive forces created by the Southern Implant plastic clips ranged between 7.5 - 11.0N; for the Locatornyl on inserts the range was between 7.2 - 15.7N. Conclusion: The retentive forces of the Southern Implant clips and Locator inserts provide values within the range normally suggested as necessary to resisted is placement of a denture when chewing sticky food. However, the data from this study is not entirely consistent with that of the manufacturers.
