Partial and total edentation has been a real problem worldwide and at all times. The realization of an individualized treatment plan for each form of edentation takes into account the particularities of the edentulous prosthetic field and the materials used as well as the conventional or modern techniques applied. The study group consisted of 220 patients in whom dental implants were inserted; the control group was randomized from 10 patients with a favorable evolution out of the 210 (94.55%). At 7 and 60 days after the insertion of the dental implants and 6 months after their prosthetic loading, crevicular fluid and peri-implant fluid was harvested, for the quantitative determination of Osteoprotegerin (OPG) and Interleukin 1β (IL1-β). Of the 220 patients studied, 10 developed peri implantitis (5.45%) as follows: 4 patients with mucositis and 6 patients with severe form. The results obtained show that there are differences with statistical significance between the OPG values obtained in crevicular fluid in healthy compared to patients with mucositis after 7 days (p <0.001). Regarding IL1-β, there are differences with high statistical significance between the levels in healthy patients and those with peri-implantitis after 7 days (p <0.001). Our results show the existence of a high correlation between the clinical status and these two parameters, especially after the determinations performed at 7 and 60 days. In conclusions, the present study shows that the OPG and IL1-β can be considered useful markers in the evaluation of the patient after the insertion of the dental implant and after its prosthetic loading.
