Neutral zone dentures versus conventional dentures in diverse edentulous periods

ABSTRACT

The objectives of this study were to compare the arrangement of teeth according to the bone support concept with the neutral zone concept, Evaluate the influence of two arrangement schemes on denture success. A total of 128 patients were equally allocated into two groups, according to period of edentulism. All groups were provided neutral zone and conventional dentures. Post insertion assessment of conventional and neutral zone dentures was compared. Both denture techniques showed satisfactory assessment results in shorter edentulous period. In longer edentulous period, neutral zone dentures showed better assessment results. Arrangement of teeth with neutral zone may improve denture success in patients with prolonged edentulous periods
