Osseodensification enables bone healing chambers with improved low-density bone site primary stability: an in vivo study

Abstract Primary implant stability is a prerequisite for successful implant osseointegration. The osseodensification technique (OD) is a non-subtractive drilling technique that preserves the bone tissue, increases osteotomy wall density, and improves the primary stability. This study aimed to invest...
