The technique of immediate implant placement was first described by Lazzara in 1989. This one-step surgical procedure reduces treatment time, improves esthetic out-comes, increases comfort during healing, and has proven to be a predictable strategy with a high success rate in absence of periapical lesions. The presence of active infection in the extraction site is considered one of the main contraindications to immediate implant insertion in the socket because of the increased possibility of infection spreading to peri-implant tissues during the healing period. Photodynamic therapy is based on the idea that nontoxic photosensitive agent, called photosensitizer activated by light with susceptible wavelength and produces singlet oxygen and free radicals, which are cytotoxic for the target cells. This technique has proven to reduce periapical infection and so provide more success rate for immediate implant in infected sockets.
