Background and Aims: To find out the primary stability in maxillofacial implant with two different thread designs. Methods: Two group of implants were selected for the study – Group I maxillofacial implant with V-shape thread, and Group II implant with buttress thread. The drills for placing the implant were made indigenously. Goat skull was selected for placing the implant. Group I, II implant was placed in the goat skull at five different sites to find the primary stability. The primary stability was measured using Resonance Frequency Analysis (RFA) device. The transducer was screwed to the implant and made to vibrate by magnetic pulse. The vibration was recorded as Implant Stability Quotient (ISQ). Results: The ISQ values of Group I range from 32-46 and Group II range from 57-67. The results were subjected to statistical test and found to be significant at 95% level. Conclusion: The ISQ values for the buttress (Group II) is more than (Group I) which is observed in this study. Hence this study supports the buttress thread as the favourable thread pattern for the craniofacial implant.
