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.

Drug Information available for: Rosin

Arm Intervention/treatment
Experimental: 0.6 mm tread pitch implant Device: 0.6 mm tread pitch implant
0.6 mm tread pitch implant will be used

Experimental: 0.1 mm tread pitch implant Device: 0.1 mm tread pitch implant
0.1 mm tread pitch implant will be used

Primary Outcome Measures :
  1. To document the outcome of bone remodeling around IBT implants [ Time Frame: 3 years after implantation ]

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