BACKGROUND The aim of the present study was to evaluate the relationship between insertion torque and stability of miniscrews in terms of resistance against dislocation, then comparing a self-tapping screw with a self-drilling one. METHODS Insertion torque was measured during placement of 30 self-drilling and 31 self-tapping stainless steel miniscrews (Leone SpA, Sesto Fiorentino, Italy) in s...

PURPOSE The authors evaluated, under conditions simulating implant placement, the cutting efficiency, durability, heat production, and wear of implant drills. MATERIALS AND METHODS Osteotomies were performed on bovine ribs using a surgical unit mounted in a testing apparatus. A software program controlled the apparatus and recorded temperatures, depths, and drilling times. Seven brands of dri...

In bone cutting, the tissue is exposed to necrosis due temperature elevation, which can significantly influence postoperative results in orthopaedic surgeries. This damage usually revealed through histological analysis show necrotic extent; however, this technique does not capture mechanical damage, essential for a full material integrity assessment. Here, with micro-mechanics, it demonstrated ...

Inferior Alveolar Nerve (IAN) transposition is an option for prosthetic rehabilitation in cases of moderate or even severe bone reabsorption for patients that do not tolerate removable dentures. The aim of the present report is to describe an inferior alveolar nerve transposition with involvement of the mental foramen for implant placement. The surgical procedure was performed under local anest...

This case report discusses a case of aseptic osteonecrosis in a cranioplasty bone flap after decompressive craniectomy, which is a known, but rare complication after autologous cranioplasty. We suggest that the pathophysiology of cranial bone flap necrosis may have a similar pathophysiology to free flap necrosis/failure. The key suggested problem causing the osteonecrosis is vessel thrombosis w...
