“…This may be due to adequate oral hygiene maintenance by the patient during post-operative evaluation period. These findings are not in accordance with multicenter longitudinal study by Van Steenberghe et al who concluded that there is a decrease of probing depth over time, 23 and George et al 24 who reported significant greater probing depths with increasing time. The Consensus report of the 1996 workshop in periodontics concluded that there is no clear evidence of value of probing depth.…”

Methods: A total of 30 completely edentulous patients male or female, in the age group of 54e78 years (mean age 65 years), wearing conventional complete dentures were selected and randomly divided in to two groups. A total of 60 implants were placed in the interforaminal area of the mental symphysis (two implants per patients) in 30 patients. Two types of attachment systems namely Ball for group-A and Bar for group-B were used and immediate loading done.Implants were evaluated clinically and radiographically at baseline, 1 month, 3 months, 6 months and 9 months. All clinical and radiographic parameters were subjected to statistical analysis.Result: The implant survival rate for group-A (ball attachment) was 93.3% and implant survival rate for group-B (bar attachment) was 93.3%. The overall implant survival rate was not dependent on the attachment system. There was no significant difference in the crestal bone loss in mesial, and distal side in implants with respect to ball and bar attachment for different period of observation (F ¼ 0.25; P ¼ 0.910; F ¼ 0.07; P ¼ 0.992 respectively). m e d i c a l j o u r n a l a r m e d f o r c e s i n d i a 7 1 ( 2 0 1 5 ) S 3 4 6 eS 3 5 4

“…Therefore, the high detection rates indicate that the risk of failure is higher in patients colonized by P. gingivalis and P. intermedia, and the importance of thorough maintenance such as professional dental plaque control has been suggested. The relationship between dental plaque control conditions in the implant region and marginal bone loss has been reported 20,[30][31][32] , suggesting the importance of plaque control in the implant region. In recent years, implant treatment has been performed in patients with periodontal disease.…”

Colonization by periodontopathic bacteria is a risk factor for peri-implantitis. The purpose of this study was to investigate the colonization by black-pigmented anaerobic bacteria that occurs between the time before fixture installation and 6 months after inserting superstructures in implant treatment in partial edentulous cases. Dental plaque was serially collected from around the natural teeth and implants in 12 patients in whom a dental implant was indicated, and Porphyromonas gingivalis and Prevotella intermedia were detected using polymerase chain reaction (PCR). One month after connecting the abutment, the detection rate of P. gingivalis per site from around the implants was 63.7% and that of P. intermedia was 50.8%. Six months after superstructure setting, the detection rate per site of P. gingivalis from around the implants was 56.8% and that of P. intermedia was 41.1%. When chromosomal DNA segmentation patterns in the isolated P. gingivalis and P. intermedia were compared using pulsed field gel electrophoresis (PFGE), the patterns in the natural teeth were in accordance with those in the implants in 3 of 4 cases (75.0%) in P. gingivalis and all cases in P. intermedia. This finding suggested that bacterial colonization around implants occurred early after the implant region was exposed to the intraoral cavity and that the bacteria were transmitted from the area around the natural teeth.

The stability of titanium dental implants is determined by osseointegration. Bone is a dynamic tissue continuously remodeled through resorption and formation, processes controlled by local cytokine production. This study investigated osseotropic cytokine expression in gingival mucosa, in the intraforamina and inferior first molar zones, during rehabilitation with implant-retained overdentures. Specimens were taken from six patients prior to placement of implants in the intraforamina bone; at connection of healing abutments; and 4, 8, and 12 months after prosthetic anchorage. Through semi-quantitative reverse-transcriptase polymerase chain-reaction, the following constitutively expressed cytokines were found at first surgical stage: interleukin-1, -6, and -8; small amounts of interleukin-11; stem cell factor; and transforming growth factor-beta1, -beta2, and -beta3. From the connection of healing abutments to 12 months after prosthetic anchorage, transforming growth factor-beta1, -beta2, and -beta3 were markedly higher than initial values. Expression of interleukin-6 and -8 decreased 8 months after prosthetic anchorage, while that of interleukin-1 increased at 12 months. In cultured gingival fibroblasts, modulation of cytokine secretion was also time-dependent. Cell culture supernatants influenced osteoclast-like multinucleated cell formation in long-term human marrow culture or osteoblast function, depending on the cytokine profile produced. These results are consistent with functional contributions of cytokines to osseointegration and minimization of posterior edentulous zone bone resorption.
