As their name suggests, “immediate implants” are embedded in the dental sockets immediately after tooth extraction. The advantages of these “same-day implants” over “delayed implants” (which are placed in partially or completely healed bone) is that they sustain bone formation that provides the best aesthetic results and enable treatment time to be shortened. Good bone quality and quantity are needed for immediate implants to be successful. The gums and adjacent teeth must be in good health, and there must be a stable and favorable relationship between opposing teeth that meet to form an occlusion (bite). Patients meeting these and other criteria who are faced with extraction of decayed or fractured teeth may want to consider the advantages of immediate implants.
P.S. Immediate implants can sometimes be outfitted with replacement teeth immediately after extraction.
