The aim of research is the assessment of functional and esthetic results of implantoprosthetic treatment in patients subject to immunosuppressive treatment after organ transplants.Materials and methods: The study encompassed a group of 21 patients in the course of maintenance immunosuppression after transplantation procedures, in whom altogether 24 implants were inserted. The control group comprised 15 people with 15 implants in place. The research protocol assumed replacing a single missing tooth with a titanium implant. After 4 months, a prosthetic reconstruction in the form of a single crown was performed. After 24 months, the preliminary assessment of treatment results was attempted. The measured parameter was crestal bone level (CBL). The mechanical assessment was performed by measuring the torque indispensable to locate the implant and by an objective measurement of implant stability.Results: The basic measured parameter of CBL median in the experimental group and in the control group amounted to 0.325 mm (min 0-max 0.95) and 0.5 mm (min 0.15-max 1.8), respectively. The comparison of CBL medians revealed lack of significant differences between the experimental group and the control group (P = 0.089).Conclusion: Patients with organ transplants can safely and effectively undergo dental implant treatment.","PeriodicalId":13309,"journal":{"name":"Implant Dentistry","volume":"28 5","pages":"447-454"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/ID.0000000000000916","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37160051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Animal and clinical studies that evaluated the association between the drilling technique and proper implant integration and survival in low-density bone were included.Results: Fifteen studies met the inclusion criteria, including 7 experimental and 8 clinical. Undersized, osteotome, Piezosurgery, and osseodensification drilling were the 4 techniques found in the literature to enhance osseointegration of implants in low-density bone. Owing to the methodological variation, meta-analysis was not performed. The 4 drilling protocols were effective in increasing primary stability, but the long-term outcome is comparable with that of the conventional surgical drilling protocol.Conclusion: There is weak evidence suggesting that any of the previously mentioned surgical techniques could enhance successful osseointegration and survival of the implants placed in low-density bone.","PeriodicalId":13309,"journal":{"name":"Implant Dentistry","volume":"28 5","pages":"500-509"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/ID.0000000000000917","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37340318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Periapical radiographs were taken at the time of implant surgery, at 3-month follow-up, and at 1-year follow-up. Univariate analysis and multiple logistic regression were performed to investigate the associations between marginal bone loss and study variables. The mRNA expression levels of 21 bone-remodeling- and tissue-healing-associated genes were analyzed by subgroup.Results: Thirty-one patients with 98 implants were followed. The incidence and mean amount of bone loss were higher for overdentures than for other prosthesis and higher for the maxilla than for the mandible. The bone loss group showed lower mRNA expression levels of runt-related transcription factor-2, bone morphogenetic protein-2, and peroxisome proliferator-activated receptor gamma-2 and higher receptor activator of NKκB ligand/osteoprotegerin (RANKL/OPG) ratio.Conclusion: Within the limitations of the study, certain genes involved in bone remodeling (runt-related transcription factor-2 [Runx-2], bone morphogenetic protein-2 [BMP-2], and peroxisome proliferator-activated receptor gamma-2 [PPARγ-2]) and RANKL/OPG are correlated with early periimplant bone loss, with the type of suprastructure and the involved jaw being significant clinical factors.","PeriodicalId":13309,"journal":{"name":"Implant Dentistry","volume":"28 5","pages":"421-429"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/ID.0000000000000904","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37160052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
