Comparison of histomorphometry and microradiography of different implant designs to assess primary implant stability.

Objectives: To contribute toward optimizing the long-term stability of dental implants. Our working hypothesis was that the degrees of immediate implant-bone contact, and hence of primary stability, would demonstrably differ between implant systems due to their different external geometries and thread designs (macro-design). This demonstration was provided in a bovine model (ex vivo) by employing and comparing histomorphometry and microradiography as evaluation methods.

Distribution of endosseous bony canals in the mandibular symphysis as detected with cone beam computed tomography.

Purpose: The purpose of this article was to investigate the distribution of endosseous bony canals in the anterior mandible using cone beam computed tomography (CBCT) technology.

Materials And Methods: Two hundred ninety-nine images based on CBCT of the anterior mandible were analyzed for the presence of endosseous canals. The bony canals were observed in relationship to the adjacent anatomical structures, and relationships between their topographic variability and patient age and gender were analyzed.
