Longitudinal Denture Maintenance in the Journal of Prosthodontics

JOP_LongitudinalIn a study now online in the Journal of Prosthodontics, Drs. Ronald L. Ettinger and Fang Qian review and report the longitudinal denture maintenance needs of an overdenture population wearing complete maxillary dentures and mandibular overdentures.

This prospective cohort study was composed of patients who had received tooth-supported overdentures from 1974 to 1994 in the Department of Prosthodontics, University of Iowa; 272 patients with 662 abutments fulfilled the inclusion criteria. Drs. Ettinger and Qian found that:

  1. The three most common denture treatment needs were adjustment of the denture bases, denture relines, or denture remakes.
  2. Older participants were less likely to need two or more denture base adjustments.
  3. Those who were not taking any medications were less likely to need their dentures repaired.
  4. Participants who had worn overdentures for more than 5 years were more likely to need remakes and participants who wore their dentures continuously were more likely to need denture base repairs.
  5. Being male was statistically associated with needing teeth replaced, while being aged 50 to 64 was statistically associated with needing more denture base adjustments or occlusal adjustments.

The authors note, "It is important for dental educators and practitioners to appreciate that patients wearing overdentures need regular recalls, because they have continuing maintenance needs that require evaluation and denture services."
