Summary

Tooth extraction is followed by ridge alteration and soft tissue collapse and recession. Different strategies were proposed to limit this collapse however, the ability of these techniques to mimic the original soft tissue level and to maintain long term stability is unclear (Slagter et al., 2014). Using customized contoured healing abutments at the time of immediate implant placement is a treatment modality to improve esthetics by maintaining the soft tissue level and contour (Ruales-Carrera et al, 2019, Perez et al, 2020). Using connective tissue grafts has been suggested to enhance and maintain soft tissue stability, however, the effect of the combined procedures for maintenance of the soft tissue morphology compared to customized healing abutments alone remains unclear (Atieh et al, 2019). In patients with non-restorable teeth in the esthetic zone, will the use of bone grafts to the dual zone with customized healing abutment vs the use of connective tissue graft with customized healing abutment in immediately placed implants shows better buccal contour avoiding horizontal collapse?

Conditions

  • Immediate Dental Implants

Interventions

PROCEDURE

immediate implant placement with particulate bone graft using the dual zone technique.

Tooth extraction and immediate implant placement as mentioned, then particulate bone graft will be packed in the gap between the implant and the buccal plate of bone and the tissue (dual zone), then will be covered by a customized healing abutment.

PROCEDURE

immediate implant placement with connective tissue grafting

Tooth extraction and immediate implant placement as mentioned. Connective tissue grafts will be harvested from the hard palate and placed at the implant sites in a supraperiosteal partial dissection pouch prepared at the buccal aspect without using vertical incisions and without flap elevation. Sutures will be used to stabilize the graft in its desired place. Followed by customized healing abutment.
