Radiographic bone level and soft tissue dimensional changes following explantation of implants affected by peri-implantitis: A retrospective exploratory evaluation.

Background: While the dimensional alteration of alveolar bone following tooth extraction have been extensively descripted in the literature, no information is available regarding potential hard and soft tissues changes following implant explantation.

Aim: To evaluate the radiographic bone healing and the horizontal and vertical soft tissue dimensional alterations at implant extraction alveoli, 6 months following implant explantation.

Material And Methods: Data from 31 patients scheduled for extraction of one implant with persisting peri-implantitis despite treatment were analysed.

Longitudinal study on the effect of keratinized mucosal augmentation surrounding dental implants in preventing peri-implant bone loss.

Background: Dental implant therapy is a well-established method of prosthetic rehabilitation of missing teeth. To maintain the health of the surrounding tissue, management of risk factors/indicators and daily maintenance are important. It still remains controversial whether a certain amount of keratinized mucosal width is essential for maintaining the health of peri-implant tissue.

The secretion of cytokines by peripheral blood mononuclear cells of patients with periodontitis and healthy controls when exposed to HS.

Hydrogen sulfide(HS) is a bacterial metabolite produced as a result of bacterial growth in subgingival pockets, suggested to partake in the pathogenesis of periodontitis. HS has previously been shown to induce the secretion of the pro-inflammatory cytokines IL-1β and IL-18 via the NLRP3 inflammasome in monocytes. To investigate the non-NLRP3 inflammasome-dependent immunological response of human peripheral blood mononuclear cells (PBMCs) of periodontitis patients and healthy controls exposed to HS .

Two- and ten-year follow-up of patients responding and non-responding to the surgical treatment of peri-implantitis: A retrospective evaluation.

Material And Methods: Following peri-implant surgery, 41 patients (213 implants) were enrolled in a supportive peri-implant therapy. At the 2-year follow-up, two groups of patients were identified, with or without residual peri-implant pockets (responding and non-responding group).

Local risk indicators - Consensus report of working group 2.

In implant dentistry, plaque control and oral hygiene practices are essential to limit the risk of complication and failure in the long term. All conditions around an implant in function that influence the load and pathogenicity of the microbiota are considered local risk indicators. They concern the prosthetic suprastructure design and the possibility for the patient to easily access each implant for plaque removal.

HS mediates increased interleukin (IL)-1β and IL-18 production in leukocytes from patients with periodontitis.

: The mechanisms involved in the interplay between the bacteria and the host cells in periodontitis are not fully understood. : To investigate the effect of the bacterial metabolite HS on the pro-inflammatory cytokines interleukin (IL)-1β and IL-18 from periodontitis patients and healthy controls, and to evaluate the composition of the subgingival microbiota with its capacity to produce HS. : Subgingival bacterial samples from patients with periodontitis (N=32) and healthy controls (N=32) were investigated for HS production and bacterial composition.

Materials And Methods: A total of 44 patients, 27 from a specialist clinic in Sweden, and 17 from a Japanese one, were included. The 44 patients had a total of 175 implants of which 84 (48%) had clinical signs of mucositis (bleeding on probing [BoP]) and no radiographic bone loss.

Intra-surgical vs. radiographic bone level assessments in measuring peri-implant bone loss.

Objective: To evaluate the accuracy between the intra-surgical and the peri-apical radiographic measurements of bone loss at implant with peri-implantitis.

Materials And Methods: A total of 46 Brånemark implants in 24 patients with diagnosis of peri-implantitis were included in the study. The amount of peri-implant bone loss occurred at those implants was measured during peri-implant surgery and compared to the radiographic bone loss measured by three independent examiners.

Primary prevention of peri-implantitis: managing peri-implant mucositis.

Aims: Over the past decades, the placement of dental implants has become a routine procedure in the oral rehabilitation of fully and partially edentulous patients. However, the number of patients/implants affected by peri-implant diseases is increasing. As there are--in contrast to periodontitis--at present no established and predictable concepts for the treatment of peri-implantitis, primary prevention is of key importance.

Clinical and microbiological findings in patients with peri-implantitis: a cross-sectional study.
