Inclusion criteria

Inclusion criteria: Totally toothless bimaxillary patients who seek total dental prosthesis service at the Faculty of Dentistry of Pernambuco (FOP / UPE) seeking their rehabilitation; Participants who agree to participate in this research by signing the Free and Informed Consent Term (ICF); Participants over 18 years old; Completely edentulous participants for at least 1 year.

Exclusion criteria

Exclusion criteria: Patient with retentive rim; Patients with neoplastic and non-neoplastic proliferative processes in the oral mucosa; Patients with changes in the oral mucosa resulting from microbial infections; Patients with neuromuscular disorders; Xerostomia; Kelly syndrome patients

Design outcomes

Primary

MeasureTime frame
Expected outcome 1: Difference in the degree of retention of complete dentures from different functional molding techniques, measured in Newton (N)

Secondary

MeasureTime frame
Expected outcome 2: Difference in edge thickness of the total prostheses of the different functional molding techniques, measured using digital software;Expected outcome 3: Difference in the total cost of complete dentures made with different functional molding techniques, measured using financial real (R$);Expected outcome 4: Difference in cost-effectiveness of total prostheses performed with different functional molding techniques, measured using the mathematical formula that establishes the result of the ratio between the difference between cost, in financial unit (R$), and effectiveness, in this case in retentivity unit in newton (N);Expected outcome 5: Difference in the contact area of the total dentures of the different functional molding techniques, measured using digital software
