“…The current results suggest that 1-mm thickness of healthy gingival tissue did not significantly affect the OCT measurements, whereas 2 mm or thicker of the tissue would remarkably decrease the sensitivity of the current OCT system. Clinically, Cardaropoli et al 46 reported that the thickness of gingival covering the implant above bone is 1.3 AE 0.8 mm at the time of implant placement and 1.6 AE 0.7 mm at the time of abutment connection. On the other hand, in the anterior region of the mouth, gingival tissue is relatively thin and the implants are required to be placed as deep as possible into the bone because of aesthetic reasons.…”

Abstract. Vertical misfit of implant-abutment interface can affect the success of implant treatment; however, currently available modalities have limitations to detect these gaps. This study aimed to evaluate implant-abutment gaps in vitro using optical coherence tomography (OCT). Vertical misfit gaps sized 50, 100, 150, or 200 μm were created between external hexagonal implants and titanium abutments (Nobel Biocare, Göteborg, Sweden). A porcine gingival tissue slice, 0.5, 1.0, 1.5, or 2.0 mm in thickness, was placed on each implant-abutment interface. The gaps were evaluated by swept-source OCT at a center wavelength of 1330 nm (Panasonic Healthcare, Ehime, Japan) with beam angles of 90, 75 and 60 deg to the implant long-axis. The results suggested that while the measurements were precise, gap size and gingival thickness affected the sensitivity of detection. Gaps sized 100 μm and above could be detected with good accuracy under 0.5-or 1.0-mm-thick gingiva (GN). Around 70% of gaps sized 150 μm and above could be detected under 1.5-mm-thick GN. On the other hand, 80% of gaps under 2.0-mm-thick GN were not detected due to attenuation of near-infrared light through the soft tissue. OCT appeared as an effective tool for evaluating the misfit of implant-abutment under thin layers of soft tissue. © The Authors.

“…This corresponded with papilla harmony of 50% at CT sites and 20% at ADM sites (Table 17). Previous studies have shown improved papilla fill at 1 or more years after crown insertion (Jemt 1997, Schropp et al 2008, Cardaropoli et al 2006. In this study ~ 50% papilla fill was achieved in 83% of the CT sites compared to 80% in the ADM sites.…”

“…Hence, the concentration of stresses in the bone should be avoided to maintain stable osseointegration following implant placement. 10 Reduced crestal bone resorption has been reported with platformswitching technique in a few studies. The bone preservation noted in platform-switching technique has been attributed to inward shifting of the implant abutment junction location or the area of stress concentration between the abutment and implant.…”

Introduction:Comparison of platform switched (PS), sloping shoulder, and regular implants on stress reduction in various bone densities with finite element analysis. Materials and methods:A total of 12 three-dimensional finite element models were built to analyze the stress distribution model. Nobel Biocare 4.3 × 8 mm regular platform replace select implant with matching diameter easy abutment, Nobel Biocare 4.3 × 8 mm replace select implant PS with 3.5 mm diameter easy abutment, Bicon 4 × 8 mm implant with 4 mm diameter sloping shoulder abutments were created virtually in compact bone density using software. The 130 N axial force and a 90 N oblique loading force were applied to the abutment to analyze the stress.Results: Under horizontal and vertical loading, the sloping shoulder implant had lesser stresses in cancellous bone when compared with PS and regular implants. Sloping shoulder implant showed more stress distribution at implant-abutment interface and at crestal area, whereas with regular implants, the stresses were distributed at cortical area. Conclusion:Sloping shoulder implant in subcrestal position is much favorable for bone growth, stress distribution, and preservation of remaining bone.
