BACKGROUND The objective of this pilot study was to evaluate the effect of local application of low-magnitude high-frequency vibration (LMHFV) on the bone healing of rabbit calvarial defects that were augmented with different grafting materials and membranes. METHODS Four calvarial defects were created in each of two New Zealand rabbits and filled with the following materials: biphasic calciu...

Background/Aim. The materials used nowadays for bone replacement do not fully meet the requirements complete regeneration, which is why new ones are being tested. Despite numerous attempts to improve tissue no fulfilling material has been found yet. This study investigated influence of poly-lactide-co-glycolide (PLGA) and polyethyleneimine (PEI) as coatings hydroxyapatite (HAP) carriers on rege...

PURPOSE To quantify the amount of bone formation in the calvarial region of Wistar rats after craniotomy using bone wax as a haemostatic agent. METHODS Surgery to produce bilateral, symmetric, full-thickness cranial defects (area: 18 mm(2)) was performed in eight animals. The right side of the cranium remained open and the edges of the left side osseous defect was covered with bone wax. Calva...

OBJECTIVES The purpose of the present study was to evaluate bone healing in rabbit critical-sized calvarial defects using two different synthetic scaffold materials, solid biodegradable bioactive glass and tricalcium phosphate granules alongside solid and particulated autogenous bone grafts. MATERIAL AND METHODS Bilateral full thickness critical-sized calvarial defects were created in 15 New ...

BACKGROUND Alloplastic materials are increasingly being used in augmentation of craniofacial defects because of its ready availability, good aesthetic outcome and absence of donor site morbidity. This paper highlights experience in the use of heat-cured acrylic in augmentation cranioplasty. SUBJECTS AND METHODS The management of three patients with anterior skull defect who presented at the D...

PURPOSE The purpose of this study was to determine the biological effects of cyanoacrylate-combined calcium phosphate (CCP), in particular its potential to act as a physical barrier - functioning like a membrane - in rabbit calvarial defects. METHODS In each animal, four circular calvarial defects with a diameter of 8 mm were prepared and then filled with either nothing (control group) or one...

LEARNING OBJECTIVES After studying this article, the participant should be able to: 1. Identify the fascial layers of the temporalis region. 2. Understand the three-dimensional nature of the orbit and upper maxillectomy defects. 3. Understand the surgical harvest of temporalis flaps and temporoparietal flaps with vascularized bone. 4. Appreciate preoperative risk factors and postoperative compl...
