Abstract


Objective: To perform a long-term clinical evaluation of the periodontium of removable partial denture (RPD) wearers, comparing the direct pillar teeth of tooth-supported and tooth-tissue supported RPDs.
Method: Fifty patients with mean age of 45 years were enrolled in the study. The individuals were examined by a single examiner at the moment of denture installation and after 3, 6, 9 and 12 months. In each exam, the following parameters were verified: gingival recession (GR), probing depth (PD), plaque index (PI), gingival index (GI) e amount keratinized mucosa (KM). All patients received oral hygiene instructions and prophylaxis and, when necessary, scaling and root planing. An analysis from the confidence interval was done to evaluate the endpoints regarding the type of denture in the direct pillar group.
Results: The tooth-tissue supported dentures showed significantly higher GR, GI and PI values, and significantly lower KM values. Over time, neither of the types of denture presented statistically significant difference from the initial to the final examination for the parameters GR, PD, KM and GI, while the PI was significant only for the tooth-supported dentures.
Conclusion: Pillar teeth adjacent to free ends presented a less favorable periodontal condition than the pillar teeth adjacent to intercalated spaces. However, the use of RPD did not aggravate the initial condition, after a follow-up period of 12 months. The findings of the study indicate that, within 1 year, there were no significant differences between the direct pillars of the tooth-supported and tooth-tissue supported dentures, and suggest the need of professional follow up for a longer period.
