cast was lubricated with a separating medium. After this, modeling wax (Deepti Dental Products, Ratnagiri, India)
was melted and poured in the ocular socket on cast. (Figure 3) After the wax became hard, the wax pattern was
removed from the cast and was checked for any air entrapment and irregularities (Figure 4).

3.1.2 Wax scleral try-in
Wax pattern was placed in the patient’s the ocular socket. A protective blepharospasm was observed when the
wax pattern was first placed in the socket, thus we waited until the spasm relaxed (Kumar et al., 2014). Wax
pattern was checked for its extensions, contour, proper fit, opening and closing movement of the eyelids with
movement of the wax pattern in up, down, lateral and circular directions. Excess wax was removed from the
pattern and again, all the movements were checked until satisfactory contours for the socket and eyelids were
obtained (Cain, 1982). The position of the iris-pupil area of the natural eye in relation to the inner canthus and the
upper and the lower eyelids were transferred to the wax pattern. The center and the peripheral area of the pupil
were marked on the wax pattern with the help of a probe. The wax pattern was removed from the socket; the
markings of the pupil were sharpened by making grooves of the periphery and the center of the pupil with the help
of a carver. (Figure 4) Again the pattern was inserted in the patient’s ocular socket and checked for the visibility
of sclera, extensions of the pupil and the center of the pupil by comparing the same with the natural eye of the
patient (Bartlett and Moore, 1973). As try-in was completed, the wax pattern was flasked and dewaxing done.
(Figure 5) The next step was to reproduce scleral shade of the normal eye. For this, shade tabs were prepared by
mixing and matching different shades and proportions of the tooth-colored acrylic (Heat cure, tooth colored
acrylic resin for crown and bridge work, DPI, India) till the color of the sclera of the other eye was replicated.
Shade B2 was selected and packing done.
