Abstract
The aim of this in vitro study was to evaluate, by means of strain gauge analysis, the effect of different implant diameters on strain around two-implants retaining a mandibular over denture with locator attachments Three acrylic models with silicon mucosal simulation was fabricated and two laboratory implnts were inserted in canine areas. According to implant diameter, the experimental casts were randomly divided into 3 groups, groupI(GI)(large)(4.2mm), groupII(GII) (medium)(3.7mm) ,groupIII(GIII)(small)(3.3mm) and all implants had a length of 13mm. Three dentures were fabricated and connected to implants with locator attachments. Four linear strain gauges were bonded to the acrylic resin at mesial, distal, buccal, lingual surfaces of each implant. 100 N static load was applied uni laterally over first premolar and molar positions. Strains were measured at mesial, distal, buccal, lingual peri-implant sites. Loading side (right) and non loading side (left)
