Laser ablation of bone for implant osteotomy preparation-modeling and an ex vivo validation study.

Mechanical drilling is currently a universal standard for implant osteotomy site preparation. Without proper cooling, high frictional heat can be generated inside the bone during drilling which may be detrimental for osteocyte survival. Mechanical fracture of bone near a drill bit surface can also impede the osseointegration process.

Use of the versatile sternocleidomastoid flap in oral and maxillofacial surgery: our experience.

Our aim was to evaluate the reliability of sternocleidomastoid (SCM) flaps in the reconstruction of defects after oral and maxillofacial resections, and summarise the ways in which morbidity can be reduced. We retrospectively enrolled 65 patients who had malignant tumours resected, and assessed the postoperative viability of the SCM flap. All complications were recorded during a follow up period of 1-64 months.
