PURPOSE This prospective, controlled split-mouth study evaluated the stability of dental implants placed in the augmented mandibular areas with alveolar segmental "sandwich" osteotomies using nonceramic hydroxyapatite (ncHA) or autogenous bone. MATERIAL AND METHODS This study included 11 bilaterally partially edentulous mandibular patients in a split-mouth design. Alveolar augmentation osteot...

Bone morphogenetic proteins are a necessary component of the fracture healing cascade. Few studies have delineated the efficacy of iliac crest bone graft and recombinant human bone morphogenetic protein 2 (rhBMP-2), especially, in comparison with the gold standard treatment of nonunion, which is autogenous bone graft alone. This study compared the outcome of patients with fracture nonunion trea...

Purpose: To investigate the periapical tissue response after root end filling with intermediate restorative material (IRM) and filling of the root-end resection bone defects with autogenous bone or a bone graft substitute in comparison to empty controls. Materials and Methods: Vital roots of the second, third and fourth mandibular premolars in six healthy mongrel dogs were apectomized. The root...

Numerous studies have been carried out to determine the effect of various types of bone transplants on the healing pattern of experimentally produced defects in animals (Maatz, Lentz and Graf 1954; Burwell 1963; Heipel, Chase and Herndon 1963; Melcher and Irving 1963; Buring and Urist 1967; Raina 1968). These have repeatedly shown that autogenous bone grafts are better than homogenous and heter...

An animal study is presented, evaluating a method of mandibular reconstruction using a poly(D,Llactide) (PDLLA) scaffold. Six goats underwent a continuity resection of the mandibular angle. The defect was bridged with a preshaped PDLLA scaffold, filled with an autogenous particulate bone graft from the anterior iliac crest, and fixed with two preshaped titanium plates. To accelerate bone healin...

Introduction: Anterior corpectomy with instrumentation and fusion is common in the treatment of fractures, tumors, infections, and kyphotic deformities of the thoracic and lumbar spine. Both autogenous (iliac crest, rib or fibula) as well as allogenous strut grafts are utilized in the reconstruction. One of the advantages of autogenous bone is thought to be the endogenous cells and growth facto...

J Korean Assoc Oral Maxillofac Surg 2012;38:221-30) Objectives: This study sought to evaluate the efficacy of collagen graft materials, as compared to other graft materials, for use in healing calvarial defects in rabbits. Materials and Methods: Ten mm diameter calvarial defects were made in ten rabbits. The rabbits were then divided into 4 groups: control, autogenous bone graft, SureOss graft,...

We prospectively evaluated the percutaneous injection of autogenous bone marrow for the treatment of active simple bone cysts in ten consecutive children with cysts in the proximal humerus, proximal femur or tibia. The treatment included percutaneous biopsy, aspiration of fluid and the injection of autogenous bone marrow aspirated from the iliac crest. All the patients became painfree after a m...

The autogenous healing potential of cement-based materials is affected by multiple factors, such as mix composition, crack width, pre-cracking age and external environmental conditions. In this study, the effects curing conditions supplementary cementitious (SCMs) on self-healing early cracks in cement mortar were investigated. Three conditions, i.e., standard curing, wet–dry cycles incubated w...
