complete denture
Conditions
Interventions
In all 15 participants (single group) the following steps will be performed:
Step 1-Evaluation of the quality of life, perception, bite force and electromyography of the masseter, temporal and orbicu
Step 2- Repetition of the evaluations of Step 1 after the patients wear their old complete dentures for 18 days, and their lower denture is relined with a resin-based material
Step 3 - Repetition of the evaluations of Step 1 after the patient wears their old dentures for another 18 days, and their lower denture is with resin increments over her occlusal (vertical dimension
Step 4 - Repetition of the evaluations of Step 1 after 30 and 100 days of wearing new complete dentures.

Eligibility
Age
40 Years to 80 Years
Inclusion criteria
Inclusion criteria: Ages 40 to 80 years. Patients ASA (American Society of Anesthesiology) I and ASA II (controlled systemic disease). Participants must be bimaxillary edentulous, have good oral health and good cognitive ability to answer questions and follow commands. Height of the upper bone ridge must be sufficient to retain the old upper complete denture during speech, chewing, swallowing, etc. The height of the lower edge must be randomized. All participants must have a vertical dimension of occlusion reduced by at least 2mm. Acrylic teeth of complete dentures must be worn, to prove that the patient really uses the pair of complete dentures daily. Participants' old complete dentures must have some functionality, that is, they must allow chewing of food, speech, swallowing and clenching of acrylic artificial teeth. Old complete dentures cannot have fractures that make it impossible to use them, or hurt the patient. Not being undershot or overshot. Participants must have healthy mucosa, that is, no signs of inflammation, traumatic injury, candidiasis, or hyperplasia. Each participant must wear the same pair of old acrylic complete dentures (base and acrylic teeth) for at least 5 consecutive years. Absence of temporomandibular disorder confirmed by the the Research Diagnostic Criteria questionnaire.
Exclusion criteria
Exclusion criteria: Old complete dentures with porcelain teeth. Patients who required the artificial teeth of their new complete dentures to be porcelain. Patients with osseointegrated dental implants, or who required dental implants. Patients with residual roots. Old complete dentures with reline material. Participants who had xerostomia problems. Participants who used complete denture fixators routinely, as these fixators can influence the masticatory function and patient perception. Alzheimer's disease. Parkinson's disease. Immunocompromised patients (eg, human immunodeficiency virus infection). Patients with a history of psychiatric disorders (eg depression), neurological disorders and salivary gland disease. History of oral surgery in the last 3 months. Mandibular and/or maxillary torus. Bucosinusal communication. Orofacial defects or anomalies. Routinely abusive alcohol consumption. Participants with a history of neurological disease, lack of coordination or mental disorders. Use of psychiatric medications that induce bruxism and xerostomia, or medications with some influence on the muscles. Use of illegal drugs. Allergy to polymethylmethacrylate (PMMA). Tumor history, or those undergoing radiotherapy and/or chemotherapy. People who are partially or completely dependent on third-party care. Those uncooperative or unwilling to participate.
