ClinicalTrials.gov Identifier:
NCT01158664
First received: July 7, 2010
Last updated: December 4, 2014
Last verified: December 2014
  Purpose
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.

Condition Intervention
Dental Implants
Device: 0.6 mm tread pitch implant
Device: 0.1 mm tread pitch implant

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Subject)
Primary Purpose: Treatment
Official Title: A Prospective Multicenter Randomized Controlled Clinical Study on Conical Southern Implants With Different Thread Pitch

Further study details as provided by University Hospital, Ghent:

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

Secondary Outcome Measures:
  • To clinically and radiographically document the placement of both IBT implant thread types in the same patient [ Time Frame: over 2 years ]
  • 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 ]

Estimated Enrollment: 50
Study Start Date: January 2010
Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
