AuthorsAbstractDental implant placement in post-extraction sites remains a critical aspect of contemporary implant dentistry, with the timing of implant insertion significantly influencing clinical and esthetic outcomes. Immediate and delayed implant placement protocols are widely utilized, each presenting distinct biological, surgical, and prosthetic considerations. Immediate implant placement involves insertion at the time of extraction and aims to preserve alveolar bone architecture, reduce treatment duration, and enhance patient satisfaction. In contrast, delayed implant placement allows for complete healing of the extraction socket, providing a more stable and predictable environment, particularly in cases with infection, bone defects, or compromised soft tissue conditions. The biological processes following tooth extraction, including bone remodeling and soft tissue healing, play a fundamental role in determining implant success. Immediate placement relies on achieving primary stability within the residual bone, whereas delayed placement benefits from secondary stability through bone maturation. Comparative clinical evidence indicates that both protocols demonstrate high survival rates when appropriate case selection and surgical principles are followed. However, differences may exist in marginal bone loss, esthetic outcomes, and complication risks, which are influenced by factors such as implant positioning, soft tissue biotype, and loading protocols. Advancements in surgical techniques, biomaterials, and digital technologies have enhanced the predictability and accuracy of implant placement, allowing clinicians to tailor treatment approaches to individual patient needs. A comprehensive understanding of biological principles, clinical protocols, and modifying factors is essential for optimizing outcomes. The selection between immediate and delayed implant placement should therefore be guided by an evidence-based and patient-centered approach to achieve long-term functional and esthetic success.
IntroductionThere is now predictability and general acceptance in the use of dental implant therapy as a replacement of missing teeth in this modality which provides high levels of survival chances and good functional and esthetic outcomes. The time of exposing the tooth to the implant after the removal of the tooth is a decisive factor of the outcome of the treatment and it still is a subject of clinical controversy. Instead, immediate implant placement, which is the insertion of the implant in the extraction socket during the extraction stage, has been advocated to save on treatment time and maintain alveolar bone structure as opposed to delayed implant placement where the extraction site is completely healed before the implant can be inserted. Choosing between these methods involves taking a keen interest in the biological, mechanical and patient factors [1]. A number of clinical and retrospective studies have shown that immediate and delayed implant placements can result in high survival rates in cases of proper selection of cases and surgical practices.
