Abstract This study investigates the shrinkage of two sustainable aluminosilicate blends with fly ash or limestone-calcined clay (LC3). Paste and concrete were prepared using these SCMs for highest possible replacement binder without compromising strength. The chemical autogenous assessed paste samples further investigation conducted on hydration by thermogravimetric analysis (TGA) Fourier tran...

Early-age cracking continues to be a significant problem for new concrete construction. Two of the major contributors to such cracking are the heat released by cement hydration during the first few days of curing and the autogenous shrinkage that often occurs during the same timeframe. In this paper, three potential alternatives for reducing these contributions by modifying the concrete mixture...

In the twenty-first century, most high-performance concretes, and many other ordinary concretes, are now based on blended cements that contain silica fume, slag, and/or fly ash additions. Because the chemical shrinkage accompanying the pozzolanic and hydraulic reactions of these mineral admixtures is generally much greater than that accompanying conventional portland cement hydration, these ble...

When hard tissue augmentation is scheduled as a part of an oral rehabilitation, prior to the treatment, it is important to assess if the quality of the underlying gingiva at the recipient site can support the bone grafting procedure. The most frequent complication during autologous onlay grafts are wound dehiscences in the recipient site, so the integrity of soft tissues is a basic aspect of su...

Mandibular fractures have a high incidence among facial bone fractures that necessitated prompt treatment. The use of autogenous graft as a fixation device for mandibular fracture may have an important role in bone healing with accepted biological effect, and normal bone growth especially in pediatric patients. Moreover it avoids the side effect of both inter maxillary fixation (IMF) and bone p...

The authors describe a new material termed mineralized plasmatic matrix (MPM), a combination of platelets, fibrin concentrate, and autogenous bone to repair alveolar cleft defects. Autogenous cancellous bone is widely used to this end because such bone affords the functionalities (osteogenesis, osteoinduction, and osteoconduction) required for successful outcomes. To optimize these features, au...

PURPOSE Obtaining an answer to the question whether autogenous bone in combination with PRP give a therapeutical effect in the form of periodontal ligament attachment regeneration. Defining the degree of elimination of a convenient environment for subgingival bacterial plaque by reduction of periodontal pocket depth and periodontitis. MATERIAL AND METHODS Twenty-six systematically healthy pat...

PURPOSE To assess the esthetic and functional outcome, as well as the volume maintenance, of autogenous block grafts placed in anterior sextants of thin periodontal biotype subjects over a long-term period. MATERIALS AND METHODS Fifteen consecutive patients were followed up yearly for an average of 40 months after autogenous block grafting. Preoperative and postoperative cone beam computed to...

For the reconstruction of extensive craniofacial bony defects, autogenous bone is the material of choice because of its potential for revascularization and its osteoconductive and osteoinductive properties. In the present study, the results obtained after grafting with autogenous bone grafts in 233 patients with facial bony defects are analyzed retrospectively. At the Department of Maxillo-Faci...
