cost-effective and durable product. • Phonetics – with a one-piece structure, involving a palatal bite plane, phonetic changes are always likely and, in a small number of patients, may never resolve fully. The above is a summa- tion of the most common problems encountered and should not be seen as a definitive list. Dilemmas still exist, such as young patients with advanced periodontal disease (Figure ıı). While All-on-4 can be an attractive, cost-effective solution, these patients have an expected lifespan longer than all current data on implant survival. As a practice, we meet
regularly to discuss the merits of treatment in such cases before offering defini- tive planing to patients. Advice on longevity of any

treatment offered has to be realistic and guarded.
Summary With a well-trained and experienced team, using a well-researched and docu- mented implant system, the All-on-4 technique is a predictable and cost- effective solution to full arch rehabilitation. It is not, however, a panacea and where possible, addi- tional implants should be
planned for. Problems can and do occur, patients need to be carefully counselled about the treatment journey, expected outcomes and long-term management. These three articles have
given a brief overview of the All-on-4 concept. In the scheme of implant dentistry, it is an advanced concept and should only be undertaken after the required training and experience has been gained.
