{"title":"How often should implant-supported full-arch dental prostheses be removed for supportive peri-implant care to maintain peri-implant health? A systematic review.","authors":"Jacopo Lanzetti, Armando Crupi, Umberto Gibello, Giulia Ambrogio, Beatrice Longhi, Andrea Roccuzzo, Francesco Pera","doi":"","DOIUrl":"","url":null,"abstract":"<p><strong>Purpose: </strong>To systematically screen and summarise the available literature on when and how often it is advisable to perform supportive peri-implant care on implant-supported full-arch dental prostheses to maintain peri-implant health.</p><p><strong>Materials and methods: </strong>The authors employed the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement and the Population, Intervention, Comparison and Outcomes tool. A literature search was conducted on PubMed for randomised controlled trials, controlled clinical trials and cohort studies, reporting results on supportive peri-implant care for full-arch dental prostheses with a follow-up period of at least 1 year.

Although no specific indications can be drawn with respect to the frequency at which supportive peri-implant care should be delivered and the regime used to do so, practitioners should consider performing professional oral hygiene measures every 6 months and removing prostheses at least once per year. All interventions should be tailored to the patient's risk profile and characteristics.</p>","PeriodicalId":73463,"journal":{"name":"International journal of oral implantology (Berlin, Germany)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140159714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This clinical report presents the diagnosis, treatment planning and oral rehabilitation of a young woman with failing dentition in the anterior maxilla due to orthodontically induced root resorption. The patient's chief complaint was mobile maxillary anterior teeth 2 years after discontinuing orthodontic treatment. Radiographic and clinical evaluations revealed a missing right first premolar and left premolars and grade III mobility from the right canine to the left lateral incisor. Due to a hopeless prognosis, extraction of the maxillary anterior teeth was planned, followed by grafting procedures. Four implants were immediately placed in the fresh sockets of the canine and central sites, and a removable provisional appliance was delivered to contour the soft tissues involved. The final restorations consisted of two three-unit layered zirconia implant-supported fixed dental prostheses. Well-planned immediate implant therapy and zirconia restorations can successfully replace mobile teeth with severe root resorption caused by external surface resorption from incomplete orthodontic treatment. Combining grafting procedures during implant placement can replace hard tissue lost due to extractions, whereas provisional restorations can re-establish optimal tissue architecture in the aesthetic zone.
