About
Dimensional changes, including the loss of labial soft tissues and midfacial gingival recession, seem to be inevitable following immediate placement. The clinical relevance of this study is proposing a treatment modality namely customized healing abutment with immediate implant placement that is proposed to minimize and control midfacial gingival recession and support buccal soft tissue contour, and maintain long term stability of these tissue, which might enhance the esthetics
Full description
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).
