These statement is ridiculous, implant fixture is not similar to natural tooth , have no periodontal membrane to discern the magnitude of occlusal force. to resist the invasion of bacteria. besides, the operator can not exactly to place implant fixture parallel to the arc of closure[curve of spee] , in order to resist vertical occlusal force, rather than lateral occlusal force . to prevent the break down of alveolar bone, with result of bone saucerization. leading loss of implant. in clinical situation , crown fixual junctional gingival sulcus. have no access to let patient thoroughly to clean plaque. thus leading to chronic peri-implantitis. eventually exacerbate break down alveolar bone result implant failure. lots of literature revealed, after seven years of implantation , there were high rate of biological and mechanic complications. In traditional superior fixed denture , constructed with gingival embrasure to facilitate interproximal cleaning have long term success rate. the masterpiece of true master . serve well for more than fifty years
