Masticatory Efficiency in Implant-fixed Complete Dentures Compared to the Conventional Dentures

Study Overview
=================
Brief Summary
-----------------
Purpose of this study is to compare the masticatory efficiency 'All on four' to 'Complete dentures on a class I ridge' with a color mixing analyzing test. Ten Patients with fixed complete dentures on implants and other ten patients with complete denture on a class I ridge (Atwood) had chewed a bicolor chewing gum (Hubba Bubba ®) for different number of cycles(5-10-15-20). The chewed gum is retrieved scanned and weighted to quantify masticatory efficiency

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| color analysis mixing test | a two color chewing gum is chewed for a specific number of cycles, gum is scanned and color mixing is analysed by a software called View Gum | from 5 up to 20 second | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| weight reduction | gum is weighted before each chewing cycle than dried and weighted after chewing.weight reduction is the secondary outcome for mastication efficiency analyzing | from 5 up to 20 second |
