Eligibility
Inclusion criteria
Inclusion criteria: The study will include elderly people aged 60 years or older; totally edentulous in both dental arches, having (or not) upper and / or lower PTs considered unsatisfactory, according to Vigild's criteria (Vigild et al., 1987); must have lower residual edges classified as types III and IV, according to the American College of Prosthodontics (McGarry et al. 1999); they must present a minimum anterior bone height of 11 mm (assessed by means of panoramic radiographic examination), which is considered compatible with the 9 mm long implant installation.
Exclusion criteria
Exclusion criteria: Volunteers with cognitive impairment (assessed using the Addenbrooke Cognitive Exam, ACE-R), salivary flow below 0.6 mL/min, parafunctional habits and / or temporomandibular disorders (assessed according to RDC/TMD) will be excluded from the study, uncontrolled systemic diseases (confirmed through prior medical evaluation), and who have experience with the use of prosthetic adhesives. Volunteers with a history of neurological diseases, such as ischemic or hemorrhagic stroke, traumatic brain injury, Parkinson's disease, Alzheimer's disease, smokers or alcoholics, or those who have undergone radiotherapy in the head and neck region will also be excluded.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Swallowing threshold - It is expected to find an increase in the swallowing threshold of the experimental group compared to the control group during the evaluation period in the first and second steps. It will be evaluated by chewing a portion of peanuts, followed by chewing the test material known as Optocal.;Masticatory performance and efficiency - It is expected to find increased performance and masticatory efficiency in the experimental group compared to the control group during the evaluation period in the first phase, as well as in the second phase of the study. It will be evaluated through the sieve system, and calculated using the Rosin-Rammler equation (obtaining X50 and b).;Mixing ability - It is expected to find an increase in mixing ability compared to the control group during the evaluation period in the first and second phases of the study. It will be evaluated by the ability to mix colors during chewing a chewing gum, and after chewing the gums will be evaluated through visual and colorimetric analysis (circular variance of the hue (VOH)).;Maximum bite force - It is expected to find an increase in the maximum bite force of the experimental group compared to the control group during the evaluation period in the first and second steps of the study. It will be evaluated through a force transducer composed of pressure sensors and registered in Kilogram-force (Kgf), and later, transformed into Newton (N).;Masseter and temporal thickness - It is expected to find an increase in the thickness of the masseter and anterior temporal muscles of the experimental group compared to the control group during the evaluation period in the first and second phases of the study. It will be evaluated using ultrasound equipment with a precision of 0.1 mm, and the muscle thickness (mm) will be expressed as the average values of relaxation and maximum voluntary contraction.;Nutrition and serum level of nutrients - It is expected to find improvements in the food quality of the | — |
