Safe Harvesting of Outer Table Parietal Bone Grafts Using an Oscillating Saw and a Bone Scraper: A Refinement of Technique for Harvesting Cortical and “Cancellous”-Like Calvarial Bone

A prospective study on the morbidity resulting from calvarial bone harvesting for intraoral reconstruction

“…Although potentially severe complications can occur when grafting calvarial bone, such as accidentally entering the superior sagittal sinus, dural tears, intracranial lesions, and coup/contrecoup lesions, 6 it seems that these complications are rare 6 and can be avoided by using the correct technique, as used in this study. 11 The dura was exposed in four cases during removal of the complete graft. The diploic space was difficult to identify in these cases.…”

Comparative finite element analysis of skull mechanical properties following parietal bone graft harvesting in adults

“…Since the first description of calvarial bone harvest using burrs, chisels, hammer, and trepan (Raulo and Baruch, 1990;Tessier, 1982), other tools have been developed, including oscillating saw, bone scraper (Schortinghuis et al, 2012), and piezoelectric devices (Gonzalez-Lagunas and Mareque, 2007). Our model was built on the basis of an ideal harvesting with no irregularity and with a homogeneous thickness of the remaining parietal bone, thus underestimating mechanical behavior changes as compared to actual clinical practice.…”

Patients’ appreciation of pre-implant augmentation of the severely resorbed maxilla with calvarial or anterior iliac crest bone:a randomized controlled trial

“…The scraper was used to collect copious amounts of cancellous-like bone. To remove the graft without breaking, parallel saw cuts were made in situ [16]. Next, the graft was removed piece by piece.…”
