The preservation of height and width dimensions and the soft tissue around the postextraction socket is very significant to place an implant. After teeth extraction, the newly formed bone in the alveolar ridge cannot reach the original level in three dimensions, particularly in bone level of the buccal which results in the scarcity of bone when the implants are placed. The purpose of the preservation of the sites of the alveolar ridge and the soft tissue will help maintain height and width dimensions and soft tissue around the alveolar ridge. The method will provide the enough three-dimension capacity of bone and the aesthetic shape. The purpose of this article is to summarize the method and transplantable material of the preservation of the sites of the alveolar ridge and the soft tissue in the field of dental implant.
