Prevalence of Midline Fracture in Mandibular Complete Denture

Abstract

Patients wearing complete dentures whether both arches or a single mandibular denture pose a great problem
of midline fracture. They are more evident in patients who have retained their natural maxillary teeth. Few
reports are available on the incidence of mandibular complete denture and its management. This study aims
to evaluate the prevalence of midline fractures in mandibular complete denture .This study was designed as a
retrospective clinical study. All the patients with Complete dentures who have been treated at the department
of Prosthodontics from June 2019-March 2020 were included in the study. A total of 915 patients wearing
complete dentures in the age group 40-80 years were included in the study .Various parameters namely
midline fracture , denture age and the arch were evaluated.The data was analysed and results were recorded.
In the present study , out of 915 only 11 patients reported with complete denture fractures predominantly
within 5 years of denture use. Midline fracture was found to be more prevalent in mandibular complete
denture than maxillary complete denture.Patients wearing dentures for less than or equal to 5 years had
a higher frequency of denture fracture in both maxilla(0.22%) and mandible(0.66%).The prevalence of
midline fracture in mandibular complete denture was found to be 17.2%.
