数据说明

Conditions: Peri-Implantitis, Sinusitis, Sinusitis, Acute, Sinusitis, Chronic, Implant Infection, Dental Implant Failure Nos. Background Scientific evidence regarding the influence of peri-implantitis on Schneider’s membrane thickening is scarce and limited. Similarly, to date, there is no literature documenting the resolution of implant-associated maxillary sinusitis with peri-implantitis after treatment of peri-implantitis or removal of the implant. Objectives Therefore, the aim of this case-control study is to investigate the association between peri-implantitis and maxillary sinusitis. On the other hand, the changes that occur at the level of the maxillary sinus membrane after treatment of peri-implantitis or after implant explantation will be evaluated. Hypothesis H01: The presence of implants placed in the posterior maxillary region affected by peri-implantits is associated with sinus membrane thickening or maxillary sinusitis. H11: The presence of implants placed in the posterior maxillary region affected by peri-implantits is not associated with sinus membrane thickening or maxillary sinusitis. H02: Treatment of peri-implantitis in implants placed in the posterior maxillary region can resolve maxillary sinusitis or reduce sinus membrane thickening. H12: Treatment of peri-implantitis on implants placed in the posterior maxillary region cannot resolve maxillary sinusitis or reduce sinus membrane thickening. Material and methods Study design The study will present a case-control design. Patients will be retrospectively recruited from a private clinic exclusively dedicated to periodontics and implantology (Clínica CICOM, Badajoz, Spain). Study setting The study will be conducted in a private practice associated with the Universitat Internacional de Catalunya (UIC). The study protocol and informed consent will be reviewed by the Ethics Committee of the Universitat Internacional de Catalunya (UIC, Barcelona, Spain) and the Declaration of Helsinki, 1975, revised in 2013, will be followed. Study population All patients included in the study will sign the corresponding informed consent form
