introduction : osteon® is an alloplastic material containing 70% hydroxyapatite and 30% β-tcp. calcitonin, a hormone produced by the thyroid gland, not only prevents bone resorption by reducing both the number and the activity of osteoclasts, but also stimulates bone formation. considering the favorable effects of calcitonin on bone formation, we hypothesized that the addition of calcitonin to ...
background: perioglasâ (pg) is an alloplastic material used for grafting periodontal osseous defects since 1995. in animal models, it has been proven that pg achieves histologically good repair of surgically created defects. in clinical trials, pg was effective as an adjunct to conventional surgery in the treatment of intrabony defects. because the molecular events due to pg that are able to al...
types of biomaterials. Two were of xenogenous origin, consisting of deproteinized bovine bone, while the other was alloplastic, based on biphasic calcium phosphate. Five New Zealand white rabbits weighing between 2900 and 3500 g were submitted to four standard 8 mm-diameter perforations at the parietal bone. Three perforations were filled with three grafts and biomaterials, of which two receive...
BACKGROUND AND AIM The maxillary sinus augmentation procedure is the most frequent method used to prepare the posterior maxillary area, with bone deficit, for the placement of dental implants. For this purpose, several types of materials have been used as bone grafts, each of these materials having a number of advantages and disadvantages. The present study is aimed at evaluating the histologic...
Augmentation of the partially edentulous ridge can significantly improve the final prosthodontic rehabilitation. For enhancing soft tissue contours in the anterior region, the subepithelial connective tissue graft is the treatment of choice. The combination of connective tissue grafts with alloplastic bone graft material can optimize the ridge augmentation and reduce post extraction defects. Th...
This article is limited to a review of bone replacement graft materials used in periodontal therapy. The source, mode of bone regeneration and the respective advantages and disadvantages of autogenous, allogenic, xenogenic and alloplastic materials are discussed.
Abstract Biomaterials are routinely used in dentistry for tissue engineering. The purpose of the present work is to compare performance a new alloplastic biomaterial (Blue-Bone®), xenogeneic (Bio-Oss®), and mixture both biomaterials with 50% autogenous bone. 32 Wistar rats underwent surgical procedure which circular disc bone was removed from calvaria trephine drill 10 mm diameter create critic...
OBJECTIVE Soft tissue (ST) dehiscence with graft exposure is a frequent complication of vertical augmentation. Flap dehiscence is caused by failure to achieve tension-free primary wound closure and by the impairment of flap microcirculation due to surgical trauma. Soft tissue expansion (STE) increases ST quality and quantity prior to reconstructive surgery. We hypothesized that flap preconditio...
BACKGROUND To date, no studies have been published in which histomorphometric data from a large group of patients comparing various biomaterials for sinus floor augmentation procedures were evaluated. MATERIALS AND METHODS A meta-analysis of the English literature from January 1993 till April 2009 was carried out. Out of 147 titles, according to our criteria, 64 articles were selected for ana...
A robust method for inducing bone-formation without an autograft has not been established. Currently, both platelet-rich plasma (PRP) and bone morphogenetic protein (BMP) have been widely investigated for their clinical use in such cases. However, their synergistic effect is still controversial and previously shown diversity of this effect depends on various factors such as the bone substitutes...
