Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
beta-TriCalcium Phosphate granules will be placed in the socket of one of the bilaterally extracted M3. After six months a first set of x-rays will be done to observe bone level at the cemento-enamel junction of the chronOS filled socket versus the non-filled socket. A second set of x-rays will be done at 12 months.

Summary
Brief summary
The primary purpose of this study is to confirm that chronOS (bone substitute) can decrease the risk of peridodontal defects following extraction of their wisdom tooth/teeth (M3) extraction.
It has been reported that by extracting the mandibular M3 bony peridontal defects can occur on the distal surface of the adjacent second molar. These bony defects are particularly present in patients who had their wisdom teeth extracted when over 26 years of age.
