Surgical treatment of peri‐implantitis: Prognostic indicators of short‐term results

Abstract

Aim: To evaluate the clinical and radiographic short-term (6 months) effect of surgical treatment of peri-implantitis, and to identify prognostic indicators affecting the outcome using a multilevel statistical model. Materials & Methods:A total of 143 implants (45 patients) with a diagnosis of progressive peri-implantitis (progressive bone loss (PBL) ≥2.0 mm and bleeding on probing (BoP)/suppuration) received surgical treatment. Clinical and radiographic parameters were assessed 6 months postoperatively. Potential prognostic indicators on subject, implant and site level prior to surgery were analysed to evaluate the effect on individual and composite outcomes using multilevel logistic regression analysis.Results: At the 6-month evaluation, none of the implants demonstrated PBL and 14% of the implants were registered with the absence of bleeding and no pocket probing depth ≥6 mm. Multilevel regression analysis identified, among others, suppuration, pocket probing depth >8 mm, bone loss >7 mm and the presence of plaque as criteria associated with the outcome. Conclusion:Resective peri-implantitis surgery seemed to reduce the amount of periimplant inflammation. However, most of the sites continued to have BoP/suppuration. Thus, long-term maintenance and evaluation is warranted. The effect of treatment was reduced by some prognostic indicators such as the presence of suppuration prior to interception and peri-implant bone loss exceeding 7 mm.

Influence of keratinized mucosa on the surgical therapeutical outcomes of peri‐implantitis

“…Following treatment, BOP was yet measured at 90% of sites in both groups after either therapies. Noticeable variations between the incidence of BOP and clinically manifested peri-implantitis was previously reported (Mombelli, Muller, & Cionca, 2012 (Koldsland, Wohlfahrt, & Aass, 2018). Both findings in addition to the results of the current study agree with the conclusions of a recent systematic review; that the extent to which BOP can identify peri-implantitis seems to be limited (Hashim, Cionca, Combescure, & Mombelli, 2018).…”

“…Noticeable variations between the incidence of BOP and clinically manifested peri‐implantitis was previously reported (Mombelli, Muller, & Cionca, ). More recently, another group reported that following surgical peri‐implantitis therapy, no BOP was demonstrated in only 14% of implants treated, and almost only 2% at patient level (Koldsland, Wohlfahrt, & Aass, ). Both findings in addition to the results of the current study agree with the conclusions of a recent systematic review; that the extent to which BOP can identify peri‐implantitis seems to be limited (Hashim, Cionca, Combescure, & Mombelli, ).…”

Surgical Treatment of Periimplantitis With Non–Augmentative Techniques

“…Finally, 10 articles were included in this review. Six prospective randomized controlled trials, 9,10,16-18, 22 1 prospective cohort study, 8 2 retrospective controlled studies, 15,23 and 1 case series 24 were designed with follow-up periods of 6 months, 9,24 1 year, 8,10,15,22,23 and 3 years. [16][17][18] The risk of bias across studies was classified as unclear risk in 5 cases (1 or more criteria missing), 8,9,17,18,22 as moderate risk in 1 case, 10 and as high risk in 4 studies (2 or more criteria missing).…”

Simulated damage of two implant debridement methods: Nonsurgical approach with Teflon and stainless steel hand scalers

“…Mechanical scaling with periodontal hand scalers and ultrasonic tips is the most common treatment of periodontal and peri-implant tissue infections. [ 7 9 10 ] Periodic scaling and cleaning of biofilm accumulation niches are a noninvasive option, acting in prevention and production of excellent clinical results. [ 7 11 12 13 ] In general, the combination of this control therapy associated with instruction and patient hygiene motivation culminates in preventing the disease progression.…”
