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

A Prospective Multicenter Randomized Controlled Clinical Study on Conical Southern Implants With Different Thread Pitch

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.

Inclusion Criteria:

• At least 18 years old
• Periodontally-healthy or periodontally-treated patients
• Smokers are included
• All types of prosthetic indications are accepted but 2 IBT type implants with different threads have to be placed in one patient on the same day. Implants can be connected or not connected in the same jaw.

Exclusion Criteria:

• All other contra indications for implant surgery
• Guided bone regeneration or use of any substitutes
• No implantation in regenerated or augmented bone
• No immediate loading cases
