Abstract

Background: The main objective of the present study was to evaluate clinically and radiographically the effect of two dental implant thread designs on implant primary stability and efficacy. Methods: Twenty dental implant units (20 non-submerged tissue levels, simple line implants with two different thread designs) were inserted in 8 patients (4 males and 4 females) with an average age of years (ranged from 22 to 43 years) were included in this study. Patients were randomly divided in two equal groups: Group 1: Patients received implants with buttress shaped thread design. Group 2: Patients received implants with combination threaded square and v-shaped Results: After 6 months; Combination Square and V- shaped thread design group showed a statistically significant increase in Osstell measurements. After 6 months; there was a statistically significant difference between Modified plaque index measurements in the two groups. There was no statistically significant difference between Crestal bone losses in the two groups. Conclusion: The use of Combination Square and V- shaped thread designed implants did not differ significantly than the use of buttress shaped threaded implants, in terms of implant stability values as well as limitation of crestal resorption, usually seen after implant loading.
