Effect of photo activated disinfection on osseointegration of immediate implants placed in infected sockets

Abstract

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.

Clinical applications of antimicrobial photodynamic therapy in dentistry

“…Although, this method comes with the risk of infection spreading to the implant's surrounding tissues in cases of active infection in extraction sockets (Quirynen et al, 2005). It is worth mentioning that aPDT has shown to be effective in reducing periapical infection in these cases and thus elevating the success rate of immediately inserted implants in infected sockets receiving this adjunctive treatment (Alghandour et al, 2018).…”
