BACKGROUND To compare the different resorption patterns between resorbable membrane barrier and periosteum after iliac block bone grafting radiographically and histologically. METHODS Eighteen mature male rabbits weighing from 2.0 to 2.5 kg were used. The recipient site was the rabbit skull, and autogenous iliac bone was used as the grafting material. The harvested iliac block bones were divi...

Bone graft and bone graft substitutes are used to provide structural support and enhance bone healing. Autogenous, allogeneic, and artificial bone grafts each have advantages and drawbacks. The development of allografts, synthetic bone grafts, and new operative techniques may have influenced the use of bone grafts in recent years. The goal of this study was to analyze the use of bone grafts and...

Interest in self-healing techniques that can enhance the performance of cementitious materials has been ever increasing over past two decades. Alongside experimental developments, a great deal progress made on development numerical models for simulating behavior. In spite this, many do not consider coupled physical processes govern healing response. addition, few are developed 3D setting is nec...

Cracking is a major concern in building applications. Cracks may arise from shrinkage, freeze/thawing and/or structural stresses, amongst others. Several solutions can be found but superabsorbent polymers (SAPs) seem to be interesting to counteract these problems. At an early age, the absorbed water by the SAPs may be used to mitigate autogenous and plastic shrinkage. The formed macro pores may...

This study reviews the outcome of implant placement in 61 patients after augmentation of severely atrophic alveolar bone with a bovine bone mineral, Bio-Oss. Bone augmentation was performed at 4 different sites: alveolar crest width, alveolar crest height, antral cavity, or nasal cavity. After a mean healing time of 11.9 months, 231 implants were placed in Bio-Oss bone. The time of loading of t...

• Water penetration in concrete with different cracks is evaluated by chloride penetration. The evaluation of self-healing through presents reliable results. UHPFRC shows better than conventional and high-performance concretes. This study a novel methodology to evaluate the capability Ultra High-Performance Fiber-Reinforced Concrete (UHPFRC) designed compare types. procedure used combines loadi...

Aim and objectives: The aim of the present study was to and xenograft combined with PRP ( after a period of six months in periodontal intra Material and methods: A split mouth design was followed, where two sites in the contra lateral quadrants with probing pocket depth of were chosen. Patients were grouped as 2, Issue 3, March, 2015. – 6 months study 1* , Sugumari Elavarasu 2 , Thangakumaran 4...

Thirteen patients were treated for elevation of the maxillary sinus floor with autogenous or composite (autogenous bone + hydroxyapatite granules) bone grafts and endosseous implants. Bone biopsies were taken both at graft positioning and at implant placement. Histologic and histomorphometric results suggest that graft architecture, conformation, and composition may influence the mean bone cont...
