Factors associated with the loss of dental implants and the impact on the quality of life / Fatores associados com a perda de implantes dentários e o impacto sobre a qualidade de vida

Abstract

Introduction: Several factors can be associated with loss of dental implants and this loss can affect the quality of life. Objective: The objective of this work was to evaluate the factors involved in the loss of dental implants as well as the impact of the loss on the individual's quality of life. Methods: This study included 25 patients who reported the loss of at least one dental implant. Personal data were collected and regarding the medical and dental history. Data such as medication use, presence of systemic diseases, smoking, and consumption of alcoholic beverages were noted. In the dental history, the items relevant to this study were whether patients installed dental implants and whether or not they were lost and how long after installation. To assess the quality of life, oral health-related quality of life, quality of sleep and anxiety trait were used the WHOQoL-bref questionnaire, oral health-related quality of life questionnaire, Sleep Assessment Questionnaire (SAQ) questionnaire and the trait-state anxiety inventory (STAI-T), respectively. In addition, the presence of dental crowding, incisal spacing, and anterior open bite were evaluated. The time elapsed between installation and implant loss was counted in months. The data were submitted to statistical analysis (Spearman, Mann-Whitney, and Kruskal-Wallis correlation and Adjusted Generalized Linear Regression). Values of p 0.05 were considered significant. Results: 25 patients participated in this study. The correlation test showed a significant moderate negative correlation between the Physical Domain of the WHOQoL-bref Questionnaire and Implant Loss Time in Months (r = -0.4689 p = 0.024). Patients with schooling up to high school lost their implants more quickly compared to patients with schooling up to higher education (? = -8.48; p = 0.047). When evaluating Implant Loss Time as an independent variable, no significant results were observed. Conclusion: The early loss of dental implants affects the general quality of life of individuals in the physical domain and this event is associated with low schooling.
