Influence of Ball Attachment Diameter and Inter-implant Distance on Retention of Mandibular Overdenture: An in Vitro Study
Advanced Dental Journal
Objectives: To assess the effect of three different diameters of ball/ socket attachments and inter-implant distances (IIDs) on the retention of 2 implants as compared with single implant retained mandibular overdentures. Materials and Methods: Four transparent acrylic resin casts simulating a completely edentulous mandible were fabricated. The forces (N) needed to dislodge single and 2 implant retained mandibular overdentures were estimated by a universal testing machine. Four main groups weredoi:10.21608/adjc.2020.25279.1060 fatcat:sn5jo3sxtnbube2r6bidaipj4a
