OBJECTIVES Considering the importance of bone augmentation prior to implant placement in order to obtain adequate bone quality and quantity, many studies have been conducted to evaluate different techniques and materials regarding new bone formation. In this study, we investigated the bone healing capacity of two different materials deproteinized bovine(More)
OBJECTIVE Interleukin-1β (IL-1β) is one of the most important cytokines which seems to have an important role in the inflammatory process in gingival and peri-implant tissues. The aim of this split-mouth study was to investigate the relationship between the concentration of IL-1β in gingival crevicular fluid (GCF) and peri-implant crevicular fluid (PICF)(More)
OBJECTIVE Reconstruction methods are an essential prerequisite for functional rehabilitation of the stomatognathic system. Plasma rich in growth factors (PRGF) offers a new and potentially useful adjunct to bone substitute materials in bone reconstructive surgery. This study was carried out to investigate the influence of PRGF and fibrin membrane on(More)
OBJECTIVE Both anorganic bovine bone (ABB) and β-tricalcium phosphate (β-TCP) are used in clinical practice as bone substitute materials, but there is limited data comparing these two materials in standardized defects. The aim of this study was to histologically evaluate the effectiveness of ABB and β-TCP in the healing of experimentally induced bone(More)
OBJECTIVE The purpose of this study was to evaluate the efficacy of two types of bone substitutes, Bio-Oss and NuOss, for repair of bone defects. MATERIALS AND METHODS This study was performed on the calvaria of 14 New Zealand rabbits. The 6mm critical size defect (CSD) models of bone regeneration were used. Three CSDs were created in each surgical site.(More)
OBJECTIVE The aim of this study was to compare the lateral window and osteotome techniques for sinus lifting using histological and histomorphometric methods. MATERIALS AND METHODS In this clinical trial 10 patients (a total number of 14 sinus areas) who needed implant treatment in the atrophic posterior maxilla were enrolled. In all the cases the(More)
BACKGROUND Recent studies have shown that lactoferrin promotes the proliferation and differentiation of osteoblasts and inhibits osteoclast-mediated bone resorption. Anorganic bovine bone (ABB) graft has been extensively used as an osteoconductive material in the bone reconstructive surgeries. The purpose of this study was to examine whether the combination(More)
BACKGROUND The success of combined periodontal and orthodontic approach in the treatment of aggressive periodontitis patients with the pathologic extruded anterior teeth is a main concern and stability of the treatment results is an important factor to evaluate the treatment. The present study investigated the periodontal parameters at the end of the(More)
OBJECTIVE(S) Gingivitis is an inflammatory disease that affects tooth-supporting tissues and is caused by a microbe-immune response. The aim of this study was to evaluate the effects of omega-3 fatty acids on immune system regulation and the prevention and treatment of gingivitis using an animal model. MATERIALS AND METHODS Gingival inflammation was(More)
