520 _aThis study was conducted to investigate the effect of implant platform switching on strains developed around implants with straight and angled abutments. Samples of this study were divided into two groups: Group I: (n = 10) ten straight implants with five straight abutments with matching diameter to that of the implant (4.5 mm) (sub- group A) and five straight abutments with platform switched smaller diameter (3.75) than that of the implant.(sub- group B). Group II: (n = 10) ten inclined implants with five 15{u00BA} angled abutments with matching diameter to that of the implant (4.5 mm) (sub- group A) and five 15{u00BA} angled abutments with platform switched smaller diameter (3.75) than that of the implant.(sub- group B). All implants were inserted in epoxy resin blocks with the aid of a specially designed mould and paralleling device following a standardized protocol. The abutments were then screwed to the implants with the hex tool and torque wrench. All abutments received Ni-Cr full metal crowns representing upper premolar with non-anatomical occlusal surface following a standardized protocol. Crowns were cemented on their corresponding abutments using temporary eugenol-free cement. Epoxy resin models were prepared to receive four strain gauges around each implant. Then strain gauges were luted on the prepared epoxy blocks. After connecting the strain gauges to the strain meter, a 300 N load was applied axially on each crown using a universal testing machine at a rate of 1N/sec. The developed microstrains around each implant were recorded using a four channel strain meter
