“…placing a full occlusal load onto the implant via the prosthesis, within 72 hours after placement). [8][9][10][11][12][13] The advantages of immediately loading implants are clear: they allow for shorter treatment times and allow for immediate restoration of function and esthetics. These advantages, however, may be offset by an increased risk of implant failure.…”

Purpose-The purpose of this study was to estimate one-year implant survival for delayed versus immediately loaded implants and identify risk factors for implant failure.Materials and Methods-This was a retrospective cohort study, consisting of a sample of subjects who had ≥ 1 Bicon® dental implant placed over a 13-year period. The primary predictor variable was method of implant loading: delayed (3 -6 months after placement) or immediately after insertion. Secondary predictor variables were classified as demographic, anatomic, implant/ abutment and reconstructive. The outcome variable was implant failure, defined as removal of the implant and was recorded as months of survival. Descriptive, Kaplan-Meier, and univariate Cox proportional hazards statistics were computed. Univariate associations with p ≤ 0.15 and biologically relevant variables (e.g. age, gender) were included in a marginal multiple Cox regression model. In the multiple model, a p-value ≤ 0.05 was considered statistically significant.Results-The study sample consisted of 677 subjects who had 2349 delayed loaded dental implants and 178 patients who had 477 immediate loaded implants. The unadjusted one-year survival estimates for the delayed and immediate loading groups were 95.5% and 90.3%, respectively (p < 0.01). In the marginal multiple Cox regression model, immediate loading, current tobacco use, maxillary implants, and shorter implants were associated with failure (p ≤ 0.05).Conclusion-In this study, immediately loaded implants were 2.7 times (after adjusting) more likely to fail at one-year compared to delayed loaded implants.

“…In a method described by Tames et al, 20 patient driven. [4][5][6][7][8][9][10][11][12][13][14][15][16][17] The initial reports on immediate loading of mandibular implants used extra or expendable implants that were placed into function with a temporary fixed restoration at surgery. [4][5][6][7] A clinician's decision about whether to rehabilitate an edentulous patient or a patient who requires that all of his or her teeth be removed immediately is made based on evidence that this method is as successful as traditional delayed techniques.…”

“…Table 1-1 summarizes classic papers on the immediate loading of mandibular implants; these reports verify that sufficient evidence exists that this procedure is acceptable and no longer should be considered experimental. 5,[7][8][9][10][11][12][13][14][15][16][17] The reasons cited for implant failure in immediate loading of the edentulous mandible include placement of short implants into the posterior mandible, bruxism, poorly fitting prostheses, poor surgical technique, and infection of the implants. The success rates ranged from 84.7% to 100%, indicating that immediate loading of the edentulous mandible is a viable treatment.…”

“…Brånemark et al recommended a stress-free unloaded healing period in order to minimize the risk of implant failure [1,2]. However, to achieve the targeted success rate, a strict protocol needs to be followed even if patients encounter pain with prolonged use of uncomfortable interim prostheses [2][3][4]. Recently, researchers have begun to focus attention on intermediate loading at the post-surgery stage, as well as the parameters for gauging successful loading.…”

Bones adjust their structure to withstand the mechanical demands they experience. It is suggested that flow-derived shear stress may be the most significant and primary mediator of mechanical stimulation. In this study, we designed and fabricated a fluid flow cell culture system that can load shear stress onto cells cultured on 3D scaffolds. We evaluated the effect of different culture techniques, namely, (1) continuous perfusion fluid flow, (2) intermittent perfusion fluid flow, and (3) static condition, on the proliferation of osteoblasts seeded on partially deproteinized bones. The flow rate was set at 1 ml/min for all the cells cultured using flow perfusion and the experiment was conducted for 12 days. Scanning electron microscopy analysis indicated an increase in cell proliferation for scaffolds subjected to fluid shear stress. In addition, the long axes of these cells lengthened along the flowing fluid direction. Continuous perfusion significantly enhanced cell proliferation compared to either intermittent perfusion or static condition. All the results demonstrated that fluid shear stress is able to enhance the proliferation of cells and change the form of cells.© Versita Sp. z o.o.
