Restoration of mandible discontinuity defects continues as a challenge for maxillofacial surgeons. Despite the development of algorithms for reconstruction plates fixation and autogenous grafting techniques, complications are still encountered including screw loosening, bone resorption or delayed/incomplete union. The aim of the study was to analyze the possibility of obtaining bone union in th...

Abstract This study aimed to investigate the effect of autogenous healing capacity with addition expansive and crystalline agents on mechanical fracture behaviors fiber-reinforced (FR) mortar specimens crack mouth opening displacement (CMOD) controlled test set-up. The experimental results a self-healing approach FR were analyzed in terms first cracking peak load (FCPL) increase, index toughnes...

Background: Although some surgical techniques have been described for the operative treatment of unstableOsteochondritis dissecans (OCD) of the knee, outcomes are variable and are not satisfying totally. The aim of thepresent study is to evaluate the outcomes of autogenous osteochondral grafting for OCD of the knee.Methods: In a case series study, from June 2014 to July 2015, ...

In the present study, effect of autogenous peritoneum graft (PG) with platelet rich fibrin (PRF) was evaluated on intestinal anastomosis healing in dogs. Eighteen local breed adult dogs were anesthetized then jejunal resection and created all animals. Animals divided into 3 equal groups (6 for each). first group (control): An end-to-end performed using simple interrupted suture pattern only. PG...

BACKGROUND An increased rate of pseudarthrosis has been documented following posterolateral lumbar spine grafting in patients who smoke. This same relationship has been assumed for anterior cervical interbody grafting, but to our knowledge it has never been proven. This study compared the long-term radiographic and clinical results of smokers and nonsmokers who had undergone arthrodesis with au...

Concrete is very sensitive to crack formation. As wide cracks endanger the durability, repair may be required. However, these repair works raise the life-cycle cost of concrete as they are labor intensive and because the structure becomes in disuse during repair. In 1994, C. Dry was the first who proposed the intentional introduction of self-healing properties in concrete. In the following year...

BACKGROUND The optimal treatment option for osteochondritis dissecans of the knee is still controversial. We report the case of a boy who developed osteochondritis dissecans in the lateral femoral condyles of his bilateral knees requiring repeat surgical procedures. There has been no literature reporting juvenile osteochondritis dissecans of bilateral knees requiring repeat surgical procedures....
