Ridge preservation using demineralized freeze-dried bone allograft and chorion membrane

Abstract

Socket and ridge preservation are emerging as innovative techniques to minimize the postextraction hard and soft tissue collapse. The exaggerated tissue loss in case of compromised sockets often presents an esthetic and prosthetic dilemma to the clinician. This case report shows the potential of demineralized freeze-dried bone allograft (DFDBA) in conjunction with human chorion membrane to manage such a case. A 22-year-old male patient underwent a tooth extraction due to a failed endodontic treatment. A missing buccal wall of socket was managed by using ridge preservation using DFDBA in conjunction with the human chorion membrane. Six months follow-up revealed that the loss of tissue height was 0.36 mm, and loss of tissue width was found to be 2.04 mm. Use of DFDBA in conjunction with human chorion membrane proved to be effective in minimizing soft/hard tissue loss and also helped in some amount of tissue gain.
