Abstract

Background and Aims: With increasing age and inability to maintain good oral hygiene, the chances of tooth loss increase and the need for dental implants will increase in the future. It also increases the risk of developing peripheral implants, especially at older ages in the failure of implant treatments. Recently, the high prevalence of cardiovascular disease and peri-implantitis in the elderly has been reported. The aim of this study was to investigate the effect of cardiovascular disease on the peri-implantitis in people with failed dental implants.
Materials and Methods: In this retrospective study, the files of patients referred to Shahid Montazeri Dental Clinic from 2009 to 2018 whose their failed implants were extracted, were collected. There were a total of 793 people with failed dental implants. The variables of this study were demographic information including age and sex, health status in terms of cardiovascular disease and peri-implantitis, which were identified and then statistically analyzed by examining the files of patients with these two variables. Data were statistically analyzed by SPSS25 statistical software and Chi-square was used to determine the effective variables.
Results: A total of 793 patients had failed dental implants, including 368 women (46.4%) and 425 men (53.6%) with an average age of 50.79 years. 42 patients (5.3%) had heart disease and 44 (5.5%) had peri-implantitis. According to the Chi-squared test, the significance level was less than 0.05 (P=0.011).
Conclusion: The results of this study showed that the cardiovascular disease and peri-implantitis were significantly related.

Abstract

Background and Aims: Although dental implants have become a successful and predictable ong-term treatment for patients, not all implant treatments are necessarily successful and pre-implant diseases are spreading. The aim of this study was to determine the prevalence of peri-implantitis in patients one year after prosthetic loading in Khorramabad in 2021.
Materials and Methods: In this cross-sectional study, 53 patients who had implants and undergone prosthetic loading for one year were studied. In each of the 53 patients, the probing depth (PD) and bleeding during probing (BOP) around the implant and the characteristics of the surrounding soft tissue, including gingival redness and tissue sensitivity were evaluated and recorded. To assess the bone level or possible bone resorption, a P.A. graph was taken from the patient using a parallel technique. Information such as demographic characteristics and specialized information about the disease were collected through a checklist. Data were collected using SPSS22 software. Frequency tables and chi-square and t-tests were used to analyze the data.
Results: The mean age of patients participating in the present study was 46.5±10.63 years. The number of women was 33 (62.3%). The prevalence of peri-implantitis was 17% at the patient level and 9.3% at the implant unit level. There was a significant relationship between the age (P<0.03) and systemic disease (P<0.03) with the prevalence of peri-implantitis. However, there was no statistically significant relationship between the prevalence of peri-implantitis and other demographic variables (P<0.05).
Conclusion: The results of the present study showed that the prevalence of peri-implantitis was higher in people with a higher mean age. In addition, systemic diseases are a protective factor for peri-implantitis.

Abstract

Background and Aims: Nowadays, the best choice for replacing missing teeth are dental implants, however, failure is not unexpected. One of the factors that plays an important role in the implant failure is bacterial microleakage which could cause biological complication. The aim of this study was to compare the bacterial microleakage between the two types of implants.
Materials and Methods: In the present interventional study, SPI and Dentis implants were placed bilaterally in the premolar-molar area of the patients' mandible. One day and 14 days after the delivery of the crown, by removing the crown and removing the abutment, sampling was performed using a sterile paper cone from four areas. One day after sample culturing, the number of colonies was counted. All data were entered into SPSS 23 and were analyzed using independent samples t-test and paired t-test with a significance level of 0.05.
Results: The amount of bacteria in implant sulcus was significantly different between the two types of implants (P=0.003). After 14 days, the amount of bacteria in SPI implant sulcus significantly decreased more than Dentis implant sulcus (P=0.001). After 14 days, the amount of bacteria also decreased in all other areas which there were no significant difference between the two types of implants (P>0.05).
