Self perceived chewing function in locator retained mandibular implant overdentures

Purpose: To compare self reported outcomes of a chewing function in two- or four-implant mandibular overdentures (IOD) retained by locators, as well as to assess influence of patients' age. In spite of abundant literature on oral health related quality of life (OHRQoL) outcomes in different prosthodontic treatment options and various cohorts, the outcomes of a chewing function has not been studied as a single concept. Materials and Methods: Altogether 52 patients with mandibular IODs participated (mean age 66.54 ± 8.6 years). Patients were divided into 2 groups depending on the number of implants (locators) (30 patients with 4 and 22 two implants), age (31 patients older than 60 years ; 21 patients younger or equal 60 years), and gender (25 females and 27 males). The unidimensional Chewing function questionnaire (CFQ) was used to measure patient’s self-percieved chewing function. Summary scores of 10 questions were calculated. Statistical analysis comprised descriptive statistics, independent sample t test and 3 factor ANOVA. Results: Although slightly lower CFQ summary scores (better self assessed chewing function) were registered in the 2 implant IOD group, in females and in patients of higher age no statistically significant differences were found for single factor assessments (p>0.05). However, the 3 factor ANOVA revealed only one significant effect for the combination of two factors: number of implants and age group (p=0.028). Conclusions: Older people were more satisfied with 2 locator retained IODs. It seems to be acceptable treatment for completely edentulous elders considering chewing function.
