Abstract
This in vitro study was carried out on epoxy resin models to compare
the stresses induced by two different prosthetic options for restoring long
mandibular anterior free end saddle (Class IV Kennedy classification).
The models were prepared to simulate the oral cavity. Periodontal
ligament of the artificial teeth was simulated by adding 0.3mm silicone
material around the roots. Oral mucosa simulation was also simulated by
adding an even layer of 2 mm silicone material over the ridge area.
On the epoxy resin models, different prosthetic designs were
constructed as follow:
Model A:
Lower removable partial denture with extra-coronal resilient precision
attachment on the splinted first and second premolars on both sides as a
direct retainer and lingual plate as a major connector was fabricated.
Model B:
Lower removable partial overdenture retained with single symphyseal
implant and attachment on first premolars on both sides and lingual plate as a
major connector. The implant was placed in the midline according to the
instructions of the manufacture.
The attachment used for this study was OT strategy because it is
esthetically accepted.
