Treatment of Peri-implantitis Using a Combined Decontaminative and Regenerative Protocol: Case Report
No full textPeri-implantitis is a long-term complication that frequently occurs after implant surgery. Several treatment methods have been proposed that are aimed at arresting the disease and potentially regenerating bone defects related to it. The use of a combination of proposed decontaminative treatments could possibly improve outcomes. In this case report the authors describe a combined mixed protocol, in which chemical decontamination and a laser-assisted decontamination technique are used in a surgical regenerative approach to successfully manage and treat a case of peri-implantitis. The combined surgical and antimicrobial protocol described can be a suitable treatment option in cases in which implants show severe bone resorption as a result of peri-implant disease
On Generalized Petrovsky Parabolic Systems
No full text[Madguerova Andreana S.; Маджуерова Андреана С.]A generalization of the Petrovsky parabolic systems is proposed in this article; “a priori” estimates for them are examined; their characterizing inclusions for some spaces of complex-valued functions with strong generalized derivatives of L. Schwartz-Sobolev type are given
Peri-implant disease: What we know and what we need to know
Full text linkPeri-implant disease is a serious problem that plagues today's dentistry, both in terms of therapy and epidemiology. With the expansion of the practice of implantology and an increasing number of implants placed annually, the frequency of peri-implant disease has greatly expanded. Its clinical manifestations, in the absence of a globally established classification, are peri-implant mucositis and peri-implantitis, the counterparts of gingivitis and periodontitis, respectively. However, many doubts remain about its features. Official diagnostic criteria, globally recognized by the dental community, have not yet been introduced. The latest studies using metagenomic methods are casting doubt on the assumption of microbial equivalence between periodontal and peri-implant crevices. Research on most of the features of periimplant disease remains at an early stage; moreover, there is not a commonly accepted treatment for it. In any case, although the evidence so far collected is limited, we need to be aware of the current state of the science regarding this topic to better understand and ultimately prevent this disease

Simultaneous implant placement and vertical ridge augmentation with a titanium-reinforced membrane: a case report
No full textAbstract: The present report demonstrates a clinical approach to achieve vertical ridge augmentation around endosseous implants. Two implants were placed, leaving the threads exposed, in the atrophic mandibular right posterior quadrant of a male patient. Both implants were covered with a titanium-reinforced expanded polytetrafluoroethylene (e-PTFE) membrane. Second-stage surgery was performed 12 months after implant placement Upon membrane removal, growth of mineralized tissue was observed around both implants, covering areas previously not covered by bone. Implants were then progressively loaded and restored. Titanium-reinforced e-PTFE membranes can be satisfactorily used for vertical augmentation of atrophic ridges
Active implant peri-apical lesion: a case report treated via guided bone regeneration with a 5-year clinical and radiographic follow-up.
No full textImplant peri-apical lesion (IPL) is a periapical lesion, usually asymptomatic, in which the coronal portion of the implant achieves a normal bone to implant interface. A case of IPL following immediate implant placement and treated with guided bone regeneration (GBR) principles is described. Five-year clinical and radiographic follow-up with cone-beam assessment showed complete healing of the bone. GBR principles applied to IPL could completely solve the lesion
