AB  - One of the major purposes of making a
prosthesis based on implant is to produce a superstructure
by a Passive Fitness. If such a Passive Fitness is not met,
then the implant components will fail which will
ultimately result in the failure of the treatment. The aim of
this research is to assess the effect of Splint on the
dimensional variations of implant location transfer with a
25° angle by Open Tray Molding Method using polyether
material. The research by an experimental-laboratory
method was rendered on 15 specimens by 3 implant
systems, tantamount to 45 specimens in each group and
with 6 points (A-F). In order to produce the master cast of
Velmix gypsum type IV and a vacuumed blender were
used. By either of the Splint and Non-Splint techniques,
15 times molding was separately performed. Upon
hardening of the gypsum, for a concurrent measurement
of the casts, they were placed on the mantining plate by
use of a clamp and by a multi axes Coordinator (x-y-z), it
was used on the upper surface of the hex implant and the
base of the cast. The statistical analysis used in this
research was T-Test. The results of the research showed
that the range of the dimensional variations of the implant
location transfer by Non-Splint technique estimated at
170.2±68.4 and by Splint technique it was estimated at
169.8±71.7 and the T-Test demonstrated that statistically
such difference was not significant. Thus, given that the
Non-Splint molding method did not show a significant
effect in diminishing the dimensional variations by Splint
method and due to ease of manipulation and reduced time
of molding process, the Open Tray Non-Splint method is
recommended.
