Preventive measures include patient education and motivation, supportive peri-implant therapy and routine assessment of the hard and soft tissues.

As such, the primary purpose of the present review was to gain further insight into the diagnostic accuracy of probing as a clinical tool to monitor dental implants and assist clinicians in preventing peri-implant diseases. Studies have recommended periodic probing to monitor the condition of the peri-implant tissues. Increased probing pocket depth, profuse bleeding on probing and suppuration at implants are clinical signs that have been associated with peri-implantitis; thus, if these clinical parameters are present, radiographic assessment is encouraged to make a definitive diagnosis considering potential inaccuracies related to local and/or systemic factors identified in the present review.</p>","PeriodicalId":73463,"journal":{"name":"International journal of oral implantology (Berlin, Germany)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39850056","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}

First, the preoperative data were collected from intraoral, extraoral facial and CBCT scans. Then, the aesthetic appearance of the anterior teeth was planned digitally and implant insertion was simulated. Next, virtual bone augmentation was carried out with reference to the simulated implant position, and according to the virtual augmentation, the templates for bone shell harvesting (also used for apical osteotomy and root tip resection during endodontic microsurgery) and bone shell grafting of the edentulous area were designed and fabricated. The templates for combined surgery (endodontic microsurgery and horizontal bone augmentation) consisted of one basal template and multiple interchangeable attachments via a plugin design to make guided endodontic microsurgery and digitally guided bone augmentation more efficient. Combined surgery was then carried out using the templates for guidance.
