Multiple biomaterials for immediate implant placement tissue repair: Current status and future perspectives

Abstract

AbstractImmediate oral implant placement is a widely accepted technique, known for its efficacy in reducing treatment duration, surgical visits, and overall healing time. One of the primary challenges associated with immediate implant placement is the attainment of initial stability. The inevitable loss of bone and soft tissue after extraction poses a risk to implant osseointegration in both vertical and horizontal dimensions. Guided tissue regeneration/guided bone regeneration (GTR/GBR) is a well‐established method for periodontal regeneration. However, current GTR/GBR membranes lack tissue inherent regeneration properties and necessitate combination with grafts to enhance tissue recovery. In this context, biomaterials have emerged as a promising option due to their good biocompatibility, biodegradability, and bioactive properties. They present a potential alternative to standard autologous/allograft procedures. The field of biomaterials for bone regeneration has rapidly evolved, developing new guiding materials and engineering techniques. These advances have become integral in addressing tissue defects at the immediate implant site. Various materials such as bioceramics, natural polymers, and synthetic polymers have been used for tissue repair. This article undertakes an etiological examination of tissue deficiency associated with immediate implant placement. Additionally, it reviews the advantages and disadvantages of a variety of biomaterials, aiming to provide references for clinical treatment and areas for further investigation.
