- Abstract
Purpose: The present randomized clinical trial compared the oral health‐related quality of life (OHRQoL), peri‐implant parameters, mandible movements, and maxillary complete denture movement during chewing between wearers of single‐ (1‐IOD) and wearers of two‐implant overdentures (2‐IODs) for a period of 12 months. Materials and Methods: Twenty‐one complete denture wearers were randomly allocated into two parallel groups: 1‐IOD (n = 11) or 2‐IODs (n = 10). The validated Brazilian version of the OHIP‐EDENT was used to evaluate the OHRQoL. A kinesiograph recorded maxillary complete denture movement during chewing of hard food testing (polysulphide impression material) and soft food testing (bread). Peri‐implant parameters were also recorded: plaque index (PI), bleeding on probing (BOP), and probing depth (PD). The Friedman test was used to compare the OHRQoL data and peri‐implant parameters among periods; the Mann–Whitney test was performed to compare the groups (1‐ and 2‐IODs). One‐way ANOVA and the Bonferroni test were used to compare mandible movement during chewing among periods, and the t‐test for independent samples was used to compare the groups. Maxillary complete denture movement was analyzed using three‐way ANOVA followed by the Bonferroni test. All statistical analyses were performed at α = 0.05. Results: Both treatments led to better general OHRQoL in comparison to conventional complete dentures (p < 0.001). Better OHRQoL was observed among 2‐IOD patients at the 12‐month follow up (p = 0.034). Peri‐implant parameters were similar irrespective of the group and follow‐up period. Vertical opening was significantly higher among 1‐IOD patients at 3 months (p = 0.038). Decreased maxillary denture vertical intrusions were observed with complete dentures in comparison with overdentures (p = 0.006), regardless of the food test (p = 0.251); however, vertical intrusion was significantly higher among 1‐IOD patients (p = 0.043). Conclusions: This study suggested that 1‐IOD can improve patient OHRQoL and may be similar to 2‐IODs in preservation of both peri‐implant parameters and masticatory movements.
