RESUMO:

The long-term success of implant-supported dentures is one of the supports to indicate these treatments. The aim of this study was to evaluate a set of variables that may interfere in the success of rehabilitation. The masticatory performance (PM) (granulometric method - X50 identification), oral health impact on quality of life (OHIP-EDENT), occurrence of complications and the health of the peri-implant tissues of patients with overdentures supported by 2 implants with a bar  clip retention system (G1) or with fixed complete dentures on 4 or 5 implants (G2), opposed to conventional complete denture. The peri-implant tissues were evaluated for mini-pillar biofilm (BMP), probing depth (PS), bleeding, inflammation, keratinized mucosa (MC), mucosal margin level (NMM) and bone loss (PO). Follow-up times were 3 (T1), 12 (T2), 24 (T3), 36 (T4) and 48 months (T5) after rehabilitation. To analyze the statistical differences in each group and over time the main tests used were Mann-Whitney, Wilcoxon and Friedman, with a significance level of 5%. The sample consisted of 45 patients. Among them, 32 have HE-type implants. The others (n = 13) had Cone Morse implants (CM). The mean age of the total sample, including patients with HE and CM, is 63.02 years (± 8.27). Rehabilitation groups were as follows: G1 with n = 25 (55.6%) and G2 with n = 20 (44.4%). Of these, 34 (75.6%) were women and 11 (24.4%) were men. The results showed that mean values of total OHIP increased from 5 to 6.60 and 6.71 in 2 (n = 33), 3 (n = 30) and 4 years (n = 28). In those times the same thing happened with the X50 that increased from 5.68 mm to 6.25 mm and 6.33 mm. In T4, G1 had a greater negative impact of oral health on quality of life in terms of physical dysfunction (p = 0.019). Overdenture patients experienced worsening of PM over time (p = 0.001). Regarding the complications, it is highlighted that in G1 there are 2.28 times more chances of complications occurring. Among the HE patients BMP increased over time in G2 (p = 0.042) and was higher in G2 than in G1 from T2 through T5 (p <0.05). PS values increased in G1 over time (p <0.001) and NMM was lower in G2 than in G1 at all times (p <0.05) and PO over time increased in G2 (p <0.001) and was greater than in G1 at 2, 3 and 4 years (p <0.05). When evaluating patients with HE and CM, it was possible to notice that bleeding was greater in G2 than in G1 in T3 and T4 (p <0.05) and NMM remained lower in G2 at all times (p <0 , 05). Thus, it was concluded that both treatments resemble the impact on quality of life and masticatory performance, however, patients rehabilitated with overdentures are more prone to prosthetic failure. While patients who are rehabilitated with fixed prosthesis have less favorable peri-implant tissue conditions.
