Expansion of the Zone of Keratinized Tissue for Healthy Implant Abutment Interface Using De-epithelialized Amnion/Chorion Allograft

Keratinized tissue around implants is beneficial for soft tissue stability and esthetics. The aim of this investigation is to show the use of amnion/chorion membrane to increase the keratinized tissue. Fifteen patients were grafted with the allograft at the first or second stage of implant surgery....

Description
Summary:Keratinized tissue around implants is beneficial for soft tissue stability and esthetics. The aim of this investigation is to show the use of amnion/chorion membrane to increase the keratinized tissue. Fifteen patients were grafted with the allograft at the first or second stage of implant surgery. The mean values of keratinized tissue were 1.27 ± 0.46 mm, 2.00 ± 0.38 mm, 2.80 ± 0.78 mm, and 3.27 ± 0.80 mm at the initial evaluation and 7, 15, and 60 days postsurgery (prosthetic delivery was at day 60), respectively (P <.001). Most increase occurred between 7 days up to the prosthetic delivery. Use of the amnion/chorion membrane seems to improve keratinized-tissue expansion. © 2019 by Quintessence Publishing Co Inc.
