What is the Influence of a Different Thread Pitch Design on Bone Remodelling Around Conical Southern Oral Implants?

Ghent University Hospital (UZ)

Status: Completed

Conditions: Dental Implants

Treatments: Device: 0.6 mm tread pitch implant; Device: 0.1 mm tread pitch implant

Study type: Interventional

Funder types: Other

Identifiers

NCT01158664

Details and patient eligibility

About

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.
