Aim: The Aim of this InVitro Study is to compare Retention of Ball Abutment and Locator Abutment Based On various Angulation of the Implants at 0,5,10 degree. Materials and method: A metal die is prepared according to the dimension (60*30*15mm) and the counterpart also prepared to the same dimension with the vertical stops. The die is duplicated with elastomeric impression material and the auto polymerising acrylic is poured and 3 pairs of acrylic block is prepared (Block A, Block B, Block C). Two implants are placed in acrylic Block A of which one implant is placed at 0 degree and the other implant is placed at angulation of 0 degree to the distal aspect from the mid line. In Block B two implants are placed of which one implant is placed at 5 degree and the other implant is placed at 5 degree to the distal aspect from the mid line, in the same manner in Block C two implants are placed of which one is placed at10 degree and the other implant is placed at 10 degree angulation. Angulation is measured by a device called Goniometer. Three pairs of ball abutment were hand tightened in three acrylic blocks (Block A, B, C) and the retentive component is placed in the counter part of acrylic and subjected to pull test, in the same way 3 pairs of locator abutment were tightened in 3 acrylic blocks (Block A, B, C) and the retentive component is placed in the counter part of acrylic, and subjected to pull test. Pull test is done using push /pull force measuring guage. (LUTRON FG 5000 A LT, ISO 9001, Made in Taiwan). Results: Significant difference found at locator attachment placed at 5 and 10 degree compared to ball attachment. Conclusion: As the angulation increases within locator attachment there is no significant difference in retention when placed at 0,5,10 degrees. It shows in locator attachment retention is not altered as there is increase in angulation.
