chronOS Implant Evaluation Study. The Canberra Surgicentre and Synthes Australia are conducting a clinical study to evaluate the performance of chronOS granules (bone substitute) following the extraction of wisdom tooth/teeth to prevent the risk of periodontal defects.
To measure the efficacy of beta-TriCalcium Phosphate (TCP) bone graft filler in preventing periodontal defect on the distal aspect of the M2 following M3 extraction.

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.
Eligibility
Inclusion Criteria4
- Age >= 18 years

- Agreement for return follow-up for at least 12 months.
Exclusion Criteria7
- Age < 18 years
- No adjacent M2
- Diabetic
- Chronic steroid use.
- Malignant condition
- Previous radiotherapy to the maxilla or mandible.
- Significant difference between the cementoenamel junction (CEJ) bilaterally, defined as attachment level variance of 1mm or more.

Interventions
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.
