Clinical Trial Summary

Patients who need more than 2 dental implants will be treated by the same implant type (conical 4mm diameter IBT Southern implants) but with different thread pitch design (0,6mm en 1,0mm type). In a 3 year clinical follow up period, the bone remodelling on X-rays is registered around these implants. The role of the thread pitch design will be investigated.
