A Fixed Reconstruction and Immediate Rehabilitation of Fully Edentulous Arch Using the All-on-Four Concept: Case Series.

Abstract

The implant survival largely depends on the mechanical setting in which they work as an independent entity. The implant design, number and position markedly affect the treatment plan. Deficient bone quantity and quality and presence of a vital anatomical landmark have often led the practitioners to conduct researches to find newer ways of implant insertion. One such technique is the 'All-On-4' concept, an alternative to the conventional implant therapy; lessens the amount of strain to the alveolar bone by increasing the antero-posterior spread with distal tilting the posterior implant. It is a cost-effective procedure that decreases the treatment time and the morbidity rate allowing a higher patient quality of life. The article demonstrates clinical cases describing rehabilitation of completely edentulous arches using the All-On-4 concept.
