background and aims. resonance frequency analysis (rfa) offers a noninvasive clinical measurement of stability and osseointegration of implants; it is a useful tool to establish implant loading time. the rfa values are represented by a quantitative unit called the implant stability quotient (isq) on a scale from 1 to 100. the aim of the present study was to measure the stability of astra tech a...

We present the use of deproteinized bovine bone mineral and a non-crosslinked collagen membrane for reconstruction significant alveolar defect in this clinical case report,. The patient had extensive loss anterior maxillary region, posing challenge implant placement. Therefore, ridge preservation was performed following tooth extraction, resulting horizontal regeneration. Two implants were subs...

Restoration of bone defects in the oral cavity is one of the major challenges for dental surgeon. A common example is handling of bone defect after simple tooth extraction for ridge preservation. Often delivering prosthodontic and implant treatments face difficulties during oral rehabilitations in bone defect site. Bone defect site needs to be restored in such a way to support further treatment...

Craniofacial reconstructive surgery requires a bioactive bone implant capable to provide a gradual resorbability and to adjust to the kinetics of new bone formation during healing. Biomaterials made of calcium phosphate or bioactive glasses are currently available, mainly as bone defect fillers, but it is still required a versatile processing technique to fabricate composition-gradient bioceram...

Mice are the small animal model of choice in biomedical research due to the low cost and availability of genetically engineered lines. However, the devices utilized in current mouse models of implant-associated bone infection have been limited to intramedullary or trans-cortical pins, which are not amenable to treatments involving extensive debridement of a full-thickness bone loss and placemen...

INTRODUCTION: We have previously reported on the osteogenic stimulating effect of applying rhBMP-2 in a THR defect model using a calcium phosphate paste carrier, (aBSM). This study was designed to determine the role of the aBSM carrier alone in the healing process. The specific aim was to determine whether aBSM can be used to improve bone ingrowth under two conditions 1) when uniform contact ex...

BACKGROUND Bone tissue engineering requires materials that are biocompatible, mechanically suited for bone function, integrated with the host skeleton, and support osteoinduction of the implanted cells for new bone formation. The aim of this study was to compare the osteogenic potential of xenograft with hydroxyapatite/β- tricalcium phosphate (HA/β-TCP) scaffold. METHODS New Zealand rabbits (...

parotid stafne bone defect is a very rare and infrequent variant, which is located on the buccal or lingual surface of the mandibular ascending ramus. in this paper, a case of parotid stafne defect, which was incidentally discovered during dental radiographic examination, is reported. this bone defect was observed as a lucent oval-shaped defect on the lingual aspect of the right mandibular ramu...

Total knee arthroplasty (TKA) often deal with bone defect localized in areas corresponding to tibial and femoral articular surfaces, a condition that is often observed in revision knee prosthetic surgery but occasionally in primary arthroplasty of the knee too. Such intraoperative situation, could create a main problem in maintaining proper alignment of the implant components and in establishin...
