Objective- Bone regeneration is a multifactorial phenomenon which contributed to several factors. It is reported that risedronate is effective for musculoskeletal diseases. The current study was to determine effectiveness of the risedronate-loaded nano capsules for calvaria healing in rabbit.Design- Experimental study.Procedures- 15 white adult male New Zealand rabbits were used. Fo...

The current paper presents a bacteria-based self-healing cementitious composite for application in low-temperature marine environments. The composite was tested for its crack-healing capacity through crack water permeability measurements, and strength development through compression testing. The composite displayed an excellent crack-healing capacity, reducing the permeability of cracks 0.4 mm ...

PURPOSE To evaluate bone healing in the extraction socket of the feline mandibular canine tooth after grafting. METHODS Eighteen adult cats were submitted to unilateral extraction of mandibular canine tooth and divided into three groups. In group 1 (n=6), control, the extraction socket was left empty. In group 2 (n=6), the extraction socket was filled with autogenous cancellous bone from the ...

Immunoexpression of PPAR-γ and osteocalcin proteins was evaluated for bone repair of critical-size defects (CSDs), created in rat calvaria (n=42) and treated with fragmented abdominal autogenous adipose tissue graft. Three groups (n=14) were formed: C (control - blood clot), AB (autogenous bone) and AT (fragmented adipose tissue). The groups were divided into subgroups (n=7) for euthanasia at 3...

INTRODUCTION The main problems of autogenous bone transplants are their unpredictable atrophy and their loss of structure. One key factor lies in the poor revascularization of simple onlay grafts. The the aim of this study was to evaluate the revascularization processes in autogenous bone grafts from the iliac crest to the alveolar ridge. METHODS In a sheep model, autogenous bone grafts were ...

Introduction: Structural bone allografts are frequently used to reconstruct bone defects in the extremities as well as for spinal fusion surgery. Failed healing at the graft-host junction is one of the most frequent complications of allograft surgery. However, the factors that regulate healing and graft incorporation remain poorly understood. The goal of these studies is to examine the molecula...

This paper analyzes the autogenous self-healing capacity of early-age Ultra-High-Performance Fiber-Reinforced concretes (UHPFRCs) by measuring crack closure and possible mechanical recovery on healed specimens. The main parameters considered in this research were healing exposure conditions (humidity chamber, immersion tap water, seawater heat curing) precracking levels (microcracks macrocracks...

AIM To analyse the morbidity arising from autogenous bone graft harvesting, graft resorption and implant survival in grafted sites. MATERIALS AND METHODS Only comparative clinical trials on the harvest of autogenous bone grafts were selected. Studies were excluded if they compared autogenous bone grafts to bone substitutes or vascularised free bone grafts. RESULTS A total of 24 studies were...
