Brief Summary:

Patients that may participate in this case-control study underwent dental implant surgery in the University Hospital in Ghent in 2004-2007.

According to one of our recent papers based on this patient group, 34/461 patients lost one or more implants. The goal is to invite these 34 patients, to update the anamnesis, to perform a brief clinical oral examination and to have a blood sample. The latter is necessary to identify relevant genetic polymorphisms of the patient that are associated with implant loss. Among the remaining patients that did not lose implants, another 34 'controls' will be invited for the same examinations.

Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: A Case-control Study on the Impact of Genetic Polymorphisms on Dental Implant Loss.
Study Start Date : June 2011
Estimated Primary Completion Date : December 2015
Estimated Study Completion Date : December 2015

Arm Intervention/treatment
Active Comparator: CONTROL: no dental implants lost
Group of patients who received an implant during a dental implant surgery in the University Hospital in Ghent in 2004-2007, who did not lose their implants.
Other: anamnesis
To update the anamnesis.
Procedure: oral examination
A brief clinical oral examination will be performed.
Procedure: Blood sample
A blood sample will be taken to identify relevant genetic polymorphisms.
Experimental: CASE: patients lost one or more implants
Group of patients who received an implant during a dental implant surgery in the University Hospital in Ghent in 2004-2007, but who lost one or more implants.
Other: anamnesis
To update the anamnesis.
Procedure: oral examination
A brief clinical oral examination will be performed.
Procedure: Blood sample
A blood sample will be taken to identify relevant genetic polymorphisms.



Primary Outcome Measures :
  1. genetic polymorphisms associated with implant loss [ Time Frame: after 3 to 6 years ]
    Identification of genetic polymorphisms that are associated with implant loss. It concerns only one evaluation (1 blood sample).
