many materials have been introduced for apexification each having their own advantages and disadvantages. this case report aims to present a new method of apexification using a combination of deproteinized bovine bone mineral (dbbm) and enamel matrix derivative (emd). after irrigating the canal of the maxillary right canine with 2.5 % sodium hypochlorite, a mixture of bio-oss and emd was packed...

PURPOSE This study was performed to evaluate the periodontal wound healing effect of particulate equine bone mineral on canine alveolar bone defects. METHODS Twelve adult male beagle dogs were used as study subjects. The mandibular second and fourth premolars were extracted prior to the experimental surgery, and the extraction sites were allowed to heal for 8 weeks. After periodontal probing,...

Following tooth extraction, socket grafts are commonly used to prevent incomplete healing and to optimize the bony site for implant placement (1). Many particulate, composite, and putty-like bone grafting materials either with or without a membrane have been used as socket grafts. This article introduces the layered socket grafting technique for socket grafting without the use of a membrane or ...

PURPOSE The aim of the present study was to evaluate the healing of post-extraction sockets following alveolar ridge preservation clinically, radiologically, and histologically. METHODS Overall, 7 extraction sockets in 7 patients were grafted with demineralised bovine bone mineral and covered with a porcine-derived non-crosslinked collagen matrix (CM). Soft tissue healing was clinically evalu...

The elastic modulus of cancellous bone is derived based on the measured elastic properties of separate mineral and protein phases. Adopting the mechanics of cellular solids approach, the moduli of elasticity of cancellous, deproteinated and demineralized bone are expressed in terms of the trabecular moduli of elasticity and the corresponding density ratios using the power law expressions. The Y...

Deproteinized bovine bone mineral (DBBM) and human freeze-dried bone allograft (FDBA) were compared in five patients undergoing bilateral maxillary sinus floor augmentation using DBBM on one side and FDBA on the contralateral side. After 9 months, core biopsy specimens were harvested. Mean newly formed bone values were 31.8% and 27.2% at FDBA and DBBM sites, respectively (P = .451); mean residu...

The mechanical properties of bone tissue are reflected in its micro- and nanostructure as well as in its composition. Numerous studies have compared the elastic mechanical properties of cortical and trabecular bone tissue and concluded that cortical bone tissue is stiffer than trabecular bone tissue. This study compared the progression of microdamage leading to fracture and the related local st...

statement of problem: the guided bone regeneration (gbr) technique does not always produce consistent results. bone filling within the space provided by the membrane can be incomplete. purpose: the aim of this study was to evaluate the effect of a collagen membrane (bio-gide) in combination with or without deproteinezed bovine bone mineral (bio-oss) on the healing of calvarial defects in rabbit...
