ABSTRACT
Dental Implants Have Completely Altered The World Of Edentulism; Despite The Tremendous Efforts Exerted, There Are Still Many Controversies Regarding The Retention Of Implant Attachments To Be Used In Implant Supported Overdentures Which Will Affect The Patient Satisfaction And Preference. The Question Here Arises - Will The Mandibular Magnet Implant Overdentures In Comparison To Mandibular Ball And Socket Retained Implant Overdentures Result In An Improvement On Retention?

Materials and Methods: Patients Were Randomly Assigned Into Two Equal Groups. Patients Of Group I Were Allocated To Two Implants Supported Overdenture Retained With Ball And Socket Attachment While Those Of Group II Were Allocated To Two Implants Supported Overdenture Retained With Magnet Attachment. Retention Was Measured For Each Group At Baseline, 1month, 3months And 6 Months By Using A Digital Force-meter While Patients� Satisfaction Was Assessed Using Oral Health Impact Profile Questionnaire (OHIP 14). The Assessment Was Made At Baseline (1 Week) After Denture Insertion And Six Months Follow-up Period. Result: Ball And Socket Group Showed Higher Retention Values Than Magnet Group, With No Statistically Significant Difference Between Mean Retention Loss Values In The Two Groups. Patient�s Satisfaction Was High In Both Groups With Statistically Significant Decrease In Mean OHIP-14 Scores After 6 Months In Each Group Conclusion: Implant Retained Mandibular Overdenture With Magnet Or Ball And Socket Attachments Is A Successful Treatment Option Regarding The Retention, Improved Overall Function And Patient Satisfaction Over Six Months Observation Period But With Higher Retention Values For Ball And Socket Attachments.
