Distinct differences in the incidence and prevalenceof peri-implantitis have been reported by a
numberof previous studies. In longitudinal study of 10 years including 101 subjects with 246 implants showed
prevalence rate of periimplintitis 4.7%, 11.2% & 15.1% respectively, among periodontally healthy, moderate &
severe periodontal compromised individuals.[3]A recent meta-analysis of nine studies with 1,497 participants
and 6,283 implants estimated for the frequency of peri-implant mucositis were 63.4% of participants and 30.7%
of implants, and those of peri-implantitis were 18.8% of participants and 9.6% of implants. A higher frequency
of occurrence of peri-implant diseases was recorded for smokers.[4]Findings show that peri-implant diseases are
not uncommon following implant therapy.
