Period 2: ARRPD

At the end of the third month of period 1, the second period began with crown preparation of the two distal abutments on both sides of the edentulous areas. Patients received a surveyed bridge with two extra-coronal attachments and a new RPD was constructed following standardized clinical procedures. The ARRPD was constructed and picked up intraorally using cold-curing resin (Figure 2). The patients were instructed how to use their dentures and the denture hygiene method was illustrated. Again, the participants were followed-up after 1, 2, and 3 months.

Attachment retained RPD, a, frontal intraoral view, b and c sides view.
