Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The clinical effect of the three impression methods, conventional, closed-mouth and tissue conditioner, on complete denture fabrication measured objectively by the same clinician at 1, 2, 4, and 8 weeks and three months after the final denture completion. | — |
Secondary
| Measure | Time frame |
|---|---|
| Denture quality of all three groups measured objectively by the same clinician using a comprehensive evaluation of denture quality between groups based on age, sex, or Atwood classification and the Oral Health Impact Profile-Edentulous Questionnaire 3 months after the final denture completion at follow-up visits at 1, 2, 4 and 8 weeks | — |
