Abstract

Overdentures retained by a single implant have been presented as a treatment option for patients with problems related to lack of retention and stability of your lower dentures. However, the evidence is not conclusive about the effectiveness of this treatment compared to overdentures retained by two implants. Objectives: To evaluate aspects related to treatment with overdentures retained by one or two implants, according to the following outcomes: satisfaction of the patients with their dentures, masticatory performance, jaw movements and the maxillary complete denture movements during chewing. Methodology: Patients wearing bimaxillary complete dentures will be randomly divided into two groups and then underwent to placement of one (GI) or two (GII) implants in the anterior mandible. After four months, o'rings abutments will be installed on the implants and the attachments will be connected into the lower denture. The satisfaction of the patients with their dentures, the masticatory performance, jaw movements and the maxillary complete denture movements during chewing will be evaluated in the following periods: before surgery, 3, 6 and 12 months after activation of the implants. The results for each of the variables will be analyzed statistically with a significance level of 5%, by means of the IBM SPSS Statistics, (version 19.0), using appropriate test according to the type of the variable and the adherence of the data to normality.
