简要总结
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?
