Abstract:
After tooth extraction,significant absorption occurs in the soft and hard tissues of the alveolar ridge.The goal of alveolar ridge preservation is to maintain the volume and shape of the alveolar ridge's soft and hard tissues as much as possible so as to provide suitable conditions for implant placement.Currently,there are challenges in classify-ing the socket for alveolar ridge preservation,such as the difficulty in directly guiding the selection of graft materials and clinical procedures and the insufficient space for particle xenograft maintenance,resulting in poor bone regenera-tion.Plasmatrix is an autologous blood derivative that effectively enhances tissue regeneration.This article introduced the characteristics of soft and hard tissue defects after tooth extraction and the primary applications of plasmatrix for al-veolar ridge preservation(liquid plasmatrix,solid plasmatrix membrane/plug,and plasmatrix bone blocks)as well as the proposed methods for the reclassification of sockets for alveolar ridge preservation based on soft and hard tissue defects at the extraction site to facilitate the creation of clinical recommendations.The proposed classifications are as follows:Class Ⅰ,extraction socket without bone defect,with or without soft tissue defect;Class Ⅱ,extraction socket with bone defect,both sides with bone wall defect less than 50％,with or without soft tissue defect;Class Ⅲ,extraction socket with bone tissue defect,at least one side with bone wall defect greater than 50％,with or without soft tissue defect.For the Class Ⅰ socket,a solid plasmatrix membrane or plug is inserted,followed by injection of liquid plasmatrix,using a double-layer solid plasmatrix membrane for socket closure;for the Class Ⅱ socket,plasmatrix bone blocks are inserted,followed by injection of liquid plasmatrix and secondary solidification,using absorbable collagen membrane and double-layer solid plasmatrix membrane for socket closure;for the Class Ⅲ socket,tenting screws are used to maintain height,followed by implantation of plasmatrix bone blocks,injection of liquid plasmatrix and secondary solidification,using ab-sorbable collagen membrane and double-layer solid plasmatrix membrane for socket closure.The aim of this article is to provide comprehensive knowledge of plasmatrix for oral clinicians to serve as a reference to simplify the clinical deci-sion-making process and procedures for alveolar ridge preservation.
