Recruitment & Eligibility

• Status: Recruitment completed
• Sex: Not specified
• Target Recruitment: Not specified

Inclusion Criteria

The volunteers have to present good general health, without uncontrolled systemic diseases that prevent the surgical procedure of implants installation. Volunteers should have age between 40-80 years and present partially edentulism in the lower arch (Kennedy Class I) having only the canines and incisors (from 33 to 43) and total edentulism in the upper arch. The mandible alveolar ridge must have thickness bone volume that supports the installation of the implants (condition evaluated after X-ray and CT scan).

Exclusion Criteria

Presence of parafunctional habits, smokers, alcoholics, patients with xerostomia, patients with history of symptoms of temporomandibular joints and/or muscles of mastication pain, presence of uncontrolled systemic diseases, severe periodontal disease and/or tooth mobility.

Primary Outcome Measures

Name	Time	Method
In respect of the implant based prosthesis, it is expect to find out increasing maximum bite force, reducing the size of chewed food particle, fewer masticatory cycles, and improvements on patient satisfaction, dietary intake, and quality of life of the volunteers comparing to the use of conventional removable partial dentures. These variables is going to be evaluated after two months use of each one of the mandible prosthesis respectively by the bilateral pressure sensors installed in the molar region, by the chewing of chewable test material samples, by the counting of the chewing cycles before swallowing, and by the subjective questionnaires appliance.

Secondary Outcome Measures

Name	Time	Method
Fixed implant-retained prosthesis promote higher stability during chewing and higher comfort to the patient during their use. Thus, it is expect that the best results for all the chewing variables could be found after the use of this prosthesis in relation to the other evaluated prosthesis.
