PREPLESS FULL MOUTH RESTORATION WITH FELDSPATHIC CERAMICS. A CONSERVATIVE APPROACH.
Objective: Resolve an
aesthetic problem due to the presence of microdontics by a minimally invasive
treatment with no preparation veneers and overlays.
Methods: A
26-year-old female patient came to our
dental office. Her chief complaint was
about her smile. During the first visit, photos, radiographs and
full-arch impressions were taken. The patient had no medical history of
interest.The waxed-up preliminary cast was placed in the mouth for clinical
evaluation in terms of shape, size, and length.
In the
following visit, the material was loaded into a silicone
(Aquasil,Dentsply,Milford DE,USA) guide
made on the wax-up and positioned in the patient's mouth.
All
information was collected from the mock-up using digital photography and
impression to obtain a cast. The mock-up was then removed from the mouth and
the teeth were cleaned and pumiced for impression procedures with silicone and
sent to the laboratory. Feldspathic (Noritake) ceramic veneers were obtained
and prepared for bonding. Initially the intaglio surfaces of veneers were
etched with 10% hydrofluoric acid, after washing to remove the acid, with
distilled water and cleaned ultrasonically to eliminate any residual material.
The surface was air dried and a silane coupling agent was applied, the
adhesive(Prime&Bond NT-Dentsply, Milford DE,USA) was left uncured, and
previously selected resin cement (RelyX Veneer Cement, 3M, Minnesota ,USA.) was
injected carefully into the veneer. The surface of each tooth was etched with
37% of phosphoric acid (DeTrey Conditioner36,Dentsply Konstanz, Deutschland)
for 30 seconds, washed and dried. The same adhesive used for the intaglio
surface of the ceramic was applied and also left uncured. Each restoration was
positioned on the specific tooth; excess resin cement was removed, light source
was use for curing for 40 seconds, sharp scalpel was used to remove excess
adhesive and resin cement and final
adjustments were made with a polishing system (PoGo,Dentsply,Milford DE,USA).
Results: It is
possible to achieve a full mouth restoration with minimally invasive
techniques.
Conclusion: No
preparation veneers and overlay achieved satisfactory esthetic technique
maximizing tooth conservation.
