Summary

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.

Detailed description

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

Interventions

Type	Name	Description
PROCEDURE	immediate implant placement with The Dual-Zone Therapeutic Concept	After tooth removal, implant placement, bone grafting, and screw retained provisional restoration, the contour of the ridge can change. Using dual zone grafting was claimed to minimize contour change associated with immediate anterior implants. In this technique. The implant should be placed in an optimal 3 dimensional mode . Xenograft, will be used in the gap to graft the bone and tissue zones, . The graft material helps serve as a scaffold to maintain hard- and soft-tissue volume as well as blood clot for initial healing.
PROCEDURE	Immediate implant placement with the bone shielding concept	After atraumatic tooth extraction using periotomes and luxators , socket curettage and cleaning simultaneously using an irrigation curette will be performed. Sulcular dissection of the attached tissue close to the socket orifice incisal and apically will be done using periotome to create a tunnel via the socket orifice. Dental implant will be placed. complete access of the labial plate of bone where all the regenerative materials will be performed to have the bone sheild delivered. A membrane will be inserted to the labial tunnel and tacked using 2 membrane tacks.
