Complete Denture
Conditions
Brief summary
The objective of the trial is to compare between of polyamide and rapidly prototyped (3D-printed) complete denture bases regarding retention, patient satisfaction, masticatory efficiency and microbial adhesion.
Detailed description
completely edentulous male patients will be selected from the out patient clinic of Removable Prosthodontic Department, Faculty of Oral and Dental medicine Al-Azhar University (Boys), Cairo, Egypt. patients will be selected and divided into randomly two equal groups and each patient will receive two sets of complete dentures: Group I: First, patients will receive maxillary and mandibular complete dentures constructed by polyamide thermoplastic resin. Group II: First, patients will receive maxillary and mandibular complete dentures constructed by 3D printed. Retention will be measured for all patients at delivery day, one month after delivery and three months after delivery. After that, there will be 2 weeks as a period of rest and the two groups will be reversed with reassessment at the same time interval. Patient satisfaction will be measured for all patients after 1 and 3 months follow up through a validated questionnaire. Masticatory efficiency will be measured by measuring muscle activity of the masseter and anterior fibers of the temporalis muscle on both sides for both dentures at one week, one month and three months after delivery using electromyography with three types of test foods. Microbial adhesion Samples will be collected one month after delivery of dentures, swaps will be taken from the fitting palatal surface of the upper denture, this will be done immediately after removal of the denture.
