Questa selezione è stata effettuata tramite il motore di ricerca bibliografica PubMed. PubMed è un database bibliografico contenente oltre 23 milioni di riferimenti dalla letteratura scientifica biomedica ed è prodotto presso la National Library of Medicine (NLM) dei National Institutes of Health (NIH) degli Stati Uniti. Factors related to peri-implantitis: a retrospective study Renvert S, Aghazadeh A, Hallström H, Persson GR. Department of Oral Sciences, Kristianstad University, Kristianstad, Sweden; School of Dental Sciences, Trinity College, Dublin, Ireland; Blekinge Institute of Technology, Karlskrona, Sweden. June 2013, Clinical Oral Implants Research Objectives: retrospectively, we as- sessed the likelihood that peri-im- plantitis was associated with a history of systemic disease, perio- dontitis, and smoking habits. Methods: Data on probing pocket depth (PPD), bleeding on probing (BOP), and radiographic bone lev- els were obtained from individuals with dental implants. Peri-implan- titis was defined as described by Sanz & Chapple 2012. Control indi- viduals had healthy conditions or peri-implant mucositis. Informa- tion on past history of periodontitis, Anti-infective therapy of peri-implantitis with adjunctive local drug delivery or photodynamic therapy: 12-month outcomes of a randomized controlled clinical trial Bassetti M, Schär D, Wicki B, Eick S, Ramseier CA, Arweiler NB, Sculean A, Salvi GE. Department of Periodontology, School of Dental Medicine, University of Bern, Bern, Switzerland. April 2013, Clinical Oral Impalts Research Objective: the objective of the study is to compare the clinical, microbiological and host-de- rived effects in the non-surgical treatment of initial peri-implantitis with either adjunctive lo- cal drug delivery (LDD) or adjunctive photodynamic therapy (PDT) after 12 months. Materials and methods: forty subjects with initial peri-implantitis, that is, pocket probing depths (PPD) 4-6 mm with bleeding on probing (BoP) and radiographic bone loss ≤ 2 mm, were randomly assigned to two treatment groups. All implants were mechanically debrided with titanium curettes and with a glycine-based powder airpolishing system. Implants in the test group (N = 20) received adjunctive PDT, whereas minocycline microspheres were locally deliv- ered into the peri-implant pockets of control implants (N = 20). At sites with residual BoP, treat- ment was repeated after 3, 6, 9 and 12 months. The primary outcome variable was the change in the number of peri-implant sites with BoP. Secondary outcome variables included changes in PPD, clinical attachment level (CAL), mucosal recession (REC) and in bacterial counts and crevicular fluid (CF) levels of host-derived bi- omarkers. Results: after 12 months, the number of BoP-positive sites decreased statistically sig- nificantly (P < 0.05) from baseline in both groups (PDT: 4.03 ± 1.66-1.74 ± 1.37, LDD: 4.41 ± 1.47-1.55 ± 1.26). A statistically significant (P < 0.05) decrease in PPD from baseline was observed at PDT-treated sites up to 9 months (4.19 ± 0.55 mm to 3.89 ± 0.68 mm) and up to 12 months at LDD-treated sites (4.39 ± 0.77 mm to 3.83 ± 0.85 mm). Counts of Porphyro- monas gingivalis and Tannerella forsythia decreased statistically significantly (P < 0.05) from baseline to 6 months in the PDT and to 12 months in the LDD group, respectively. CF lev- els of IL-1b decreased statistically significantly (P < 0.05) from baseline to 12 months in both groups. No statistically significant differences (P > 0.05) were observed between groups after 12 months with respect to clinical, microbiological and host-derived parameters. Conclusions: non-surgical mechanical debridement with adjunctive PDT was equally effective in the reduction of mucosal inflammation as with adjunctive delivery of minocycline micro- spheres up to 12 months. Adjunctive PDT may represent an alternative approach to LDD in the non-surgical treatment of initial peri-implantitis. Incidence of surgery related to problems with peri-implantitis. A retrospective study on patients followed-up between 2003 and 2010 at one specialist clinic Jemt T, Gyzander V, Britse AO. Department of Prosthetic Dentistry/Dental Material Science, Institute of Odontology, Sahl- grenska Academy at Göteborg University, Göteborg, Sweden; Brånemark Clinic, Public Dental Health Service, Region of Västra Götaland, Sweden. June 2013, Clinical Implant Dentistry and Related Research Background: little knowledge is available on incidence of patients treated for peri-implantitis problems in routine follow-up protocols. Purpose: the aim was to report the incidence, and clinical and radiographic characteristics related to routine follow-up patients who are surgically treat- ed for peri-implantitis problems during 8 years of inclusion. Materials and methods: patients with a history of peri-implantitis sur- gery were identified from patients examined on routine basis at one clin- ic (Brånemark clinic) between January 2003 and December 2010. Data on included patients were retrospectively retrieved and reported from dental records and radiographs. Results: on an average, 1,294 patients per year (SD 96) were followed up dur- ing inclusion period. Altogether, 134 patients had surgery related to peri-im- plantitis problems, corresponding to an average of 1.2% of followed-up pa- tientsperyear.Noprosthesiswascompletelylost,butaltogether,37implants (6% of included implants) were removed in 34 patients (25%) during these surgical interventions. Peri-implantitis surgery was observed more often in the edentulous upper jaw (p<.05), and there was a tendency that surgery increased by time of follow-up. No significant differences were found between patients provided with machined or medium-rough implant surfaces. Conclusions: incidenceofperi-implantitissurgerywasonanaverage1.2%offollowed-uppatients per year during an 8 years period of inclusion. As no data were available on patient compliance, it could be assumed that the result may underscore the clinical need. Significantly, more eden- tulous upper jaws were included compared with other treated jaw situations. Data also indicated that the need for surgery may increase by time of follow-up, but no significant differences were observed between patients provided with machined and medium-rough implant surfaces.
