Primary | Incidence of defects in impression recorded to fabricate dental prosthesis as assessed by impression quality assessment scale | Outcome assessment scale: 1. Perfect impression, no voids or defects; 2. Acceptable impression, minimal defects in non critical region; 3. Unacceptable impression, defects involving critical region. | 10 minutes | |
Secondary | Incidence of prosthesis margin defects as assessed by Marginal adaptation assessment scale | Outcome assessment scale: 1. Adequate, adapted to tooth margins; 2. Inadequate, not accurately adapted to tooth margin | 14 days | |
Secondary | Incidence of prosthesis proximal contact inaccuracy as assessed by prosthesis contact assessment scale | Outcome assessment scale: 1. Acceptable, same as natural proximal contact on contralateral side; 2. Unacceptable; either tight or open proximal contact. | 14 days |
