Brief 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.

Interventions

Healthy volunteers

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

Design outcomes

Primary

Measure	Time frame
To document the outcome of bone remodeling around IBT implants	3 years after implantation

Secondary

Measure	Time frame
To clinically and radiographically document the placement of both IBT implant thread types in the same patient	over 2 years
3. Outcome differences will be detected per implant center, per treated area in the mouth, per case of prosthetic rehabilitation	over 2 years
