Partially edentulous patients with absence of posterior teeth have less support structures (teeth and oral mucosa) with different degrees of resilience causing difficulties in the prosthetic rehabilitation on the retention, stability and comfort of removable partial dentures. Removable Partial Denture, Mastication

Procedure/surgery

The sample will be divided into two groups of thirty patients each: group 1 (control group) whose patients will be rehabilitated with removable partial dentures convencioanl group 2 (treated group, in which patients receive dental implants (implants WAS Neodoent, Curitiba, Brazil ) installed (one on each side in the region of the 2nd molar), the removable partial dentures (RPD) will be adapted for association with these implants.
The analysis of adaptation of the prosthesis and masticatory efficiency will be held in three separate stages. The first (T1), immediately after the installation of removable partial dentures (RPDs) in both groups, the second (T2), two months after the use of PRPs for the control group and treated group, the latter still prostheses not be effectively supported on implants (implants will meet in healing period), the third (T3), six months after the use of prostheses in the control group and treated group.

Primary Outcome(s)

The evaluation of remaining alveolar ridge height will be made through the base of the saddle removable partial denture, which will serve as a tray, which will put an impression material (polyether) to copy the space between the oral mucosa and the base of the saddle.

The efficiency analysis is performed by chewing chewing tablets, containing grains fuchsin inside, and when crushed release the substance into the capsule in proportion to the energy used. The chewing efficiency is calculated by measuring, with the aid of a spectrophotometer (Ultrospec 2100 pro UV / Visible Spectrophotometer ®, GE Healthcare, USA) concentration in absorbance (ABS) of the staining intensity of fuchsin solution.

Secondary Outcome(s)

The quality of life that is well defined as physical, mental, emotional and psychological, will be assessed through the questionnaire Oral Heath Impact Profile (OHIP-14)
