简要总结
Autogenous bone graft is considered to be the golden standard for grafting as it has osteoconductive , osteoinductive and osteogenic functions , however it has the problems of donor site morbidity , the need for two surgeries as well as post operative swelling and discomfort of the patient , so alternative bone grafts as alloplast has been introduced.
Coral bone has a structure which is similar to that of cancellous bone , its mechanical properties is similar to that of bone and it consists of high content of calcium carbonate scaffolds that has the advantages of being biodegradable , biocompatible and osteoconductive , they act as a carrier for growth factors and allow cell attachment , growth , spreading , differentiation and has been found to be effective bone graft
详细描述
Immediate implant placement has the advantages of better esthetics , reduction in the number of surgeries (one surgery is needed) and reduction in the time of treatment so it is more suitable and comfortable for patients .
Immediate implant placement in fresh extraction socket after tooth extraction may reduce the incidence of bone loss compared to implant placement in the healed bone.
Certain studies showed that bone resorption occurs with immediate implant placement and there is high risk of failure and complications.
The gold standard for immediate implant placement is placing bone graft around the implant to fill the jumping gap between the implant and the socket.
Certain studies showed that if the jumping gap is 1-2 mm so no grafting is needed , but if the gap is more than 2mm then bone grafting is needed .
