Effect of Soft Liner Female Housings Retaining Mandibular Two Implant-Supported Overdentures on Hand Grip Strength and Patient Satisfaction in Egyptian Males

Abstract

Introduction: Loss of natural teeth could make food consumption very difficult and leadsto malnutrition that is associated with muscle wasting. It is well known that implant-supportedmandibular overdentures increase the functional outcome, masticatory performance, nutritionalstatus and patient’s satisfaction compared with conventional complete dentures. The study aimedto evaluate the satisfaction and hand grip strength (HGS) for patients treated with two implantsupportedmandibular overdentures retained by soft liner female housings with either bar or ballattachments and opposed by maxillary conventional dentures.Materials and Methods: Twenty-one completely edentulous Egyptian males were selectedwith a mean age of 59.4 years and ranged between 53 and 67 years. Patients were allocatedrandomly into two groups: Group A (n=12) patients received Hader bar design connecting bothimplants in a straight line with soft liner female housing to retain the overdentures. Group B(n=9) patients received two ball patrices with soft liner female receptacles to retain the implantoverdentures. Patient satisfaction was measured by using 100 mm VA S questionnaire and Handgrip strength (HGS) was recorded by using handheld JAMAR dynamometer. Patients were recalledfor measurements at baseline with conventional dentures before implant placement (T0) and then6 months (T6) and 12 months (T12) after overdenture insertion. All statistical tests were 2-tailed atthe 5% level of significance.Results: From the pairwise statistical analysis, it was noticed that significant satisfaction VASvalues for bar group were higher in comparison to ball group in relation to retention and stability.Bar group revealed significantly higher HGS values from the baseline, while, Ball group exhibitedno significant differences between times of observation.Conclusion: Overdentures retained by soft liner around Hader bars splinting two implants maybe beneficial for edentulous patients with impaired nutritional status manifested by weak hand grip.
