The implant osteotomy will be initiated by pilot drill entries followed by sequential drills via the radiographic stent's sleeves to position the fixtures precisely into the pre-determined recipient sites. The Implant stability quotient (ISQ) will then be measured using an Osstell device after attaching intelligent implant pigs. Finally, the mucoperiosteal flaps will be sutured in place with 4-0 Prolene.
