Abstract

The use of endosseous implants provides dentistry, the solution in many problems. Someone who worked in early 90's may remember (1), the full arch reconstructions in periodontal teeth, the heroic attempts for endodontic treatments, root-end resections (palatal roots of molars, mandibular premolars), root resections/root separations of molars. Today no one uses these approaches, because our patients after spending time, effort, and money, want solutions with proven durability, solutions that only endosseous implants can provide (2, 3). In fixed prostodontics, natural bone, late loading, good surgery, the failure rate is something like 2% [Friberg et al. conducted a study comprising of 4641 Branemark dental implants for a period of 3 years and reported a failure rate of 1.5%(4).] My statistics in these conditions are 1%. Failure rate in immediate loading rise (9%), also in maxillary overdentures with 4 implants freestanding [15%], and when I use implants to salvage removable partial dentures [20%] (my statistics). (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18). It is believed that in the field of general dentistry the failure rate is bigger (6, 7). Also when we use removable interim rehabilitations we have to expect high failure rates.
