the type 2 protocol (early implant placement), implant placement is done approximately 4-8 weeks after tooth extraction.In the type 3 protocol (early-delayed or conventional implant placement), implant placement is done usually after 12-16 weeks, once most of the dimensional changes in the alveolar ridge have occurred. 1 IntroductIonEver since the introduction of the concept of osseointegration, implants have gained significant ground in the field of dentistry.Osseointegration, being the mainstay in implant dentistry, has been the ultimate goal for dentists to achieve, and one of the prerequisites for this to happen is that the immediate milieu around the dental implant must be conducive to proper healing and tissue regeneration.Traditionally, compromised teeth were removed, and the resultant sites were left to heal for at least 4-6 months before dental implants could be placed.However, as time evolved, researchers began to re-evaluate and scrutinize the various protocols stated by Brnemark as prerequisites for implant success.Newer discoveries have paved the way for challenging old preset protocols and replacing them with newer ones.This has mainly been made possible by a marked increase in the understanding of the physiology of bone healing.According to the International Team for Implantology (ITI) consensus, 3 basic protocols for implant placement are defined according to the time relation between tooth extraction and implant placement.In the type 1 protocol (immediate implant placement), implants are placed in fresh extraction sockets, with the aim to engage the remaining socket walls with the implant.In
