Purpose: Peri-implantitis and periodontitis are inflammatory and infectious diseases of implant and tooth-supporting tissues. Recently, the role of gene polymorphisms of immune response components in the relevant pathogenesis has been investigated. The present study was the first to evaluate the relationship between two known single nucleotide polymorphisms (SNPs) of the receptor activator of nuclear factor kappa-β (RANK) gene (rs3018362 and rs35211496) in chronic periodontitis and peri-implantitis patients in an Iranian population.
Methods: Eighty-one periodontally healthy patients, 38 patients with peri-implantitis, and 74 patients with chronic periodontitis were enrolled in this study. DNA was extracted from blood arm vein samples by using Miller's salting out technique according to the manufacturer's instructions given in the extraction kit. The concentration of DNA samples was measured using a spectrophotometer. The genetic polymorphisms of the RANK gene were evaluated using a competitive allele specific polymerase chain reaction (KBioscience allele specific PCR) technique. Differences in the frequencies of genotypes and alleles in the diseased and healthy groups were analyzed using chi-squared statistical tests (P<0.05).
Results: Analysis of rs35211496 revealed statistically significant differences in the expression of the TT, TC, and CC genotypes among the three groups (P=0.00). No statistically significant difference was detected in this respect between the control group and the chronic periodontitis group. The expression of the GG, GA, and AA genotypes and allele frequencies (rs3018362) showed no statistically significant difference among the three groups (P=0.21).
Conclusions: The results of this study indicate that the CC genotype of the rs35211496 RANK gene polymorphism was significantly associated with peri-implantitis and may be considered a genetic determinant for peri-implantitis, but this needs to be confirmed by further studies in other populations.

Purpose: This retrospective clinical study aims to analyze single-unit implant-supported restorations' clinical and radiographic outcomes comprehensively.
Materials And Methods: In this retrospective study, patients who had undergone 12 months of implant-supported singleunit fixed prosthetic treatment were scanned from the archives, and a hundred patients were included in the study. Implant success and survival rates were assessed according to the consensus decisions published at the International Oral Implantology Congress in 2007.

Purpose: The available scientific evidence on the effectiveness of the surgical treatment of peri-implantitis is limited. The aim of this study was to assess the risk of recurrence or disease progression in patients with peri-implantitis that underwent surgical treatment.
Materials And Methods: A retrospective cohort study was carried out in patients subjected to peri-implant surgery between 2015 and 2021, and with a minimum follow-up of 12 months.

Objective: To evaluate the effects of tinidazole (TNZ) combined with minocycline (MINO) on therapeutic effectiveness, bone resorption, and inflammation in peri-implantitis (PI).
Methods: This retrospective study included 96 PI patients admitted between January 2023 and February 2024. Patients were divided into a control group (n = 46) treated with MINO and a research group (n = 50) treated with TNZ plus MINO.

Dental implants are now a standard solution for replacing missing teeth, even in patients with a history of chronic periodontitis. India is often referred to as the "diabetic capital of the world," a title that reflects the country's alarming rates of diabetes prevalence. However, the risk of complications, such as peri-implantitis and implant failure, remains a concern for these patients.

Aim: To propose a modified method for establishing a peri-implantitis murine model, assess the gene expression profile and immune cell infiltration of the gingiva and alveolar bone, and evaluate the transcriptomic similarity between patients with peri-implantitis and the corresponding murine model.
Materials And Methods: A ligature-induced peri-implantitis murine model was established using an immediate implant placement approach. RNA sequencing was performed to determine the transcriptomic profiles of peri-implant tissues from mice, patients with peri-implantitis and healthy individuals.
