Introduction: Intra-oral bone grafting is a common procedure used to reconstruct the alveolar ridge and enable rehabilitation with dental implants.

Extensive alveolar bone loss can result from trauma, follow post-ablative surgery for cysts and tumours, or in cases of congenital hypodontia. Such cases provide a challenge as the defects can be of complex morphology and because patients may have limited intra-oral donor sites.

The authors describe techniques for achieving intra-oral particulate bone grafting using the safescrape device and a method of using regenerated autogenous bone blocks from third molar sockets following an atraumatic removal technique.

Cases: Bone can be harvested intraorally from are the zygoamtic buttress, mandibular ramus, body and chin. The alveolar crest can also be used. Clinical examples are used to demonstrate the versatile nature of the safescrape device and the large amount of particulate bone that can be collected and used to reconstruct alveolar defects and for sinus lifts. We also show the atraumatic technique for third molar removal to maximise bone regeneration fir subsequent block harvest.

Conclusion: Traditionally bone had been retrieved from the iliac crest for the purposes of intra oral bone grating. An extra-oral donor site has many morbities.

The authors show intra-oral sites can be donor sites and using the particulate bone can be placed in defects. We also highlight an innovative approach to in vivo bone regeneration from healed third molar sockets so blocks of bone can be used in cases where it is required.
