简要总结
Immediate implant placement has proven to be a successful treatment procedure that is preferred by patients because of being less traumatic, more time-efficient. Nowadays, the main goal of a successful immediate implant treatment has ceased to be gaining stability and osseointegration, but achieving long-term dimensional stability has become the optimal challenge. Various soft tissue and hard tissue augmentation techniques have been investigated in order to maintain the ridge dimensions following extraction and immediate implant placement.
详细描述
It has been noted that the different augmentation procedures aid in decreasing the dimensional changes occurring after immediate implant placement in the esthetic zone. Even though immediate implant placement is a predictable procedure, however, labial bone resorption following tooth extraction is inevitable. The available surgical techniques present do not entirely prevent dimensional variations of the peri-implant hard and soft tissues over time. Furthermore, substantial evidence showed that immediate implant placement failed to halt the resorption of the thin buccal bony plate with subsequent gingival recession, particularly in patients with thin gingival phenotype
