Background: Primary stability is crucial to implants used for orthodontic anchorage. Bone condensing to enhance primary stability is controversial. Material and methods: Fourteen Frialit‐2 ® ‐stepped screw and cylinder implants were placed in the median palatine sutures of 22 cadaveric human heads. In half of both types, the implant bed was prepared using a Frialit ® Bone Condenser. Primary implant stability was evaluated using non‐invasive resonance frequency analysis. Moreover, the bone–implant contact area was examined histomorphometrically and radiographically. Results: Bone condensing yielded a slightly, yet not significantly increased implant stability quotient compared with a conventional technique. In spongy bone, a significant histomorphometric increase of bone–implant contact ( P <0.0001) and a significant increase of radiographic density was revealed for both implant types, while no significant changes were observed within the compact area. Conclusion: The study shows that bone condensing yields an improved histologic implant–bone contact only in spongy bone, which was paralleled by radiographic–densitometric findings.
