ABSTRACT
This Study Was Conducted To Evaluate The Difference Between Conventional Acrylic And Soft Lined Implant Partial Overdenture In Mandibular Kennedy Class I. The Aim Of This Work Was To Evaluate The Effect Of Using Soft Liner On Denture Base In Lower Kennedy Class I Partially Edentulous Patients Restored With Implant Supported Partial Overdenture Fourteen Partially Edentulus Patients Were Selected Patients And Divided Into Two Equal Groups. For Both The First And Second Groups: Endosseous Implant Was Placed In The Edentulous Region And Loading Was Done After Three To Four Month. In The First Group Conventional Acrylic Was Used While In The Second Group The Overdenture Was Lined With Soft Liner.For Each Patient, Radiographic Evaluation Has Been Done Immediately After Denture Insertion And After 6 And 9 Month From Prosthesis Construction. The Results In This Study Showed That There Was Statistically Significant Difference Between Both Groups In Radiographic Evaluation Regarding Bone Height But Not Bone Density.
