Implant Tribune United Kingdom Edition

January 201416 Implant Tribune United Kingdom Edition proven short implant on the market that was called the Driskol Precision Implant in the early 1980s, than Stryker and the Bicon Dental Implant from 1993 (Boston, USA). The Bicon implant has a bacterially-sealed 1.5o locking taper (galling or cold weld- ing) connection5,6 between the abutment and implant, with the ability for 360o of universal abutment positioning. Having a bacterially-sealed connec- tion eliminates the bacterial flux associated with clinical odours and tastes and reduces inflammation and bone loss consistently. Another unique character- istic is the sloping shoulder that facilitates the appropriate transfer of occlusal loads to the bone when positioned below the bony crest. But more prac- tically, the sloping shoulder fa- cilitates aesthetic implant res- torations, for it provides space for the interdental papillae with bony support even when an implant is contiguous to anoth- er implant or tooth. The slop- ing shoulder design has been, since 1985, the basis of a sen- sible biological width and the origin of platform switching. The 360o of universal abut- ment positioning provides for the extra-oral cementation of crowns; the use of the cement- less and screwless Integrated Abutment Crown (IAC™)7 , the intraoral bonding of fixed bridges, which eliminates the need for cutting, indexing and soldering of bridge frame- works, multiple and easy re- moval of abutments over time; and the slight aesthetic rota- tional adjustments during and prior to the seating of a resto- ration. Clinical long-term results In the following long-term case description we can ob- serve the stability of the cr- estal bone around the sloping shoulder of the plateau im- plant. Clinically, the soft tissue contour around the Integrated Abutment Crowns indicates a healthy and stable epithelial tissue. The single-tooth implant is a viable alternative for single tooth replacement.8 Single- tooth replacement with endos- seous implants has shown sat- isfactory clinical performance in different jaw locations. Minimal or no crestal bone resorption is considered to be an indicator of the long-term success of implant restora- tions. Mean crestal bone loss ranging from 0.12-0.20mm has been reported one year after the insertion of single-tooth implant restorations.9 After the first year, an additional 0.01mm to 0.11mm of annual crestal bone loss has been re- ported on single-tooth implant restorations. Some implants demonstrate no crestal bone loss and/or crestal bone gain after insertion of definitive restorations.10 Crestal bone gain has been documented on immediate and early loaded implants with a chemically modified surface after one year of follow up.11 A six-year prospective study reported that 43.8 per cent of splinted Morse taper implants experienced some bone gain.12 Crestal bone gain has been documented around immedi- ately loaded Bicon implants.13 The factors that lead to peri- implant bone gain in different page 15DTß ‘The single-tooth implant is a viable alternative for single tooth replacement’ Fig 1 Fig 2 Fig 3 Fig 4 Fig 5 Fig 6 Fig 7 Fig 8 Fig 9 Fig 10 Fig 11 Fig 12 Fig 13 Fig 14 Fig 15 Fig 16 Fig 17 Fig 18 Fig 19 Fig 20
