Alveolar ridge augmentation using dystopic autologous tooth material
A recent study has examined the clinical outcomes of using dystopic autologous dental material for alveolar ridge augmentation and for filling jaw defects. The study, from researchers in Austria, reported on the results two years following implant placement.
The authors note that previous studies using crushed dental material to encourage bone formation had shown positive results. The present study involved 20 patients who were treated over a period of five years.
Extracted teeth were crushed using a manual bone mill. The crushed material was then used for augmentation of bone defects. In some instances, the fragments were shaped to fit the form of the defect and fixed with traction screws.
Cone-beam computed tomography (CBCT) scans were taken before and after augmentation and implantation. In total 28 implants were placed, as planned, and no issues arose during the healing period. After three months all implants were prosthetically restored. None of the implants experienced any inflammation and the average peri-implant bone loss was 0.37mm in year one and 0.58mm in year two. After the two-year period the peri-implant pocket depth was an average of 1.7mm.
Overall the study showed that the use of autologous tooth material can be used for reconstructions of defects in the alveolar ridge preceding implant placement.
This study was presented as an e-poster at the 2018 EAO Congress.
