In routine cases it may not matter which system is chosen,this is particularly the case with treatment in the anterior mandible.However,in our experience the choice of a system in any particular case depends upon:

    The aesthetic requirements

    The available bone height,width and quality(including whether the site has been grafted)

    Perceived restorative difficulties

    Desired surgical protocol

    Therefore,we should suggest the following:

    In the aesthetic zone,choose an implant where the crown contour can achieve good emergence from the soft tissue with a readily maintainable healthy submucosal margin.

    Choose an implant of the appropriate length and width for the existing crestal morphology.Ensure that choice of a reduced width implant does not compromise strength in the particular situation.

    If the site will only accommodate a short implant or if the bone quality is poor or grafted,then choose an implant with a roughened surface rather than a machined surface.

    If there are likely to be difficulties with prosthodontic construction due to difficult angulation of the implants,choose a system that is versatile enough to cope with these difficulties,i.e. has a good range of solutions/components.

    If you wish to use a submerged or non-submerged protocol,then choose a system that has a proven published record with that particular protocol.
