The master casts
were then mounted according to the MMR on a semiadjustable articulator (Dentatus Articulator ARH, Sweden) and the teeth setup was done (Figure 6).
A template was fabricated for maxillary and mandibular completely edentulous ridges on the prepared master cast
with clear autopolymerizing polymethylmethacrylate resin [Figure 4].
Boxing also permits enhanced control of the appearance and aspect of the master cast
To ensure the correct positioning of the master cast
and the tray, a device aimed at standardizing the position during the impressions was utilized.
Most of schools were teaching the students to carve the PPS and the depth of 1.0-1.5 mm in the maxillary master cast
. Compress-ibility of the palatal tissues was a consideration during PPS carving.
was blocked out and duplicated to obtain a refractory cast.
Pair of templates were fabricated on the master cast
and the patient was subjected to CBCT with the template in situ in order to select the desired length and diameter of the implants.
fabrication: The impression is delivered to the dental laboratory and a master cast
Before doing the final glaze of the crowns the restorations were placed on the maxillary and mandibular master cast
and surveyed for the fabrication of cast removable partial dentures [Fig 10].
was obtained from the impressions.(Fig 2).
