An 18-year-old female patient reported to the Department of Prosthodontics for prosthetic rehabilitation of her lost left eye. On eliciting history, it was found that the patient had sustained a shrapnel injury to her left eye, which necessitated a surgical evisceration of the eye. Clinical examination revealed a completely healed left eye socket. Her right eye had normal vision. The patient had no other relevant medical history [].\nA custom ocular tray was made by pouring autopolymerizing resin into an alginate mold made with a stock ocular prosthesis. Perforations were made in the custom ocular tray to aid in retention of the impression material, and a tunnel was cut out at the center of the custom tray to which a disposable impression tip was attached to deliver the impression material[] The impression was made by injecting light bodied addition silicone material (Aquasil Dentsply) through the prepared tunnel[] []. The patient was asked to move her eyes in all directions to facilitate flow of impression material into all aspects of the socket. Then, the patient was asked to look directly at a fixed point six feet away at the level of eye allowing impression of the site with the muscles in neutral gaze position The impression was invested first in dental stone till the height of contour and when set a second pour to create a two piece split cast mold[] [] A wax conformer was fabricated by pouring molten baseplate wax into the two pieces split cast, after which it was retrieved and the sharp edges were removed.[] The rubber stopper from a plunger tip of a tuberculin syringe was used as a removable cap which was fitted into an opening made in the posterosuperior aspect of the wax conformer A bevel was placed around the margins of the cap to help in easy removal and placement []. The wax conformer was then adjusted for the satisfactory fit, contours, and comfort An iris disk cut out from a stock eye was attached to the wax conformer using a transparent grid[] [] A needle cap was attached with cyanoacrylate adhesive to the iris disk []: To assess orientation of visual axis To stabilize and secure the iris disk during dewaxing and packing. A wire was attached to the rubber cap so that the rubber cap was retained in the same position during dewaxing and packing [] The prosthesis was invested in a dental flask. Upon separation of the flask after dewaxing, the rubber cap was retained in position by the attached wire and iris disk was retained in position by the needle cap which was attached to it [Figures and ] A mixture of clear heat cure acrylic resin and zinc oxide eugenol was packed to achieve a white scleral color.[] Lost salt technique was used to create a reservoir for the lubricant in the superior aspect of body of the ocular prosthesis[] [] A modified curing protocol (reverse curing cycle) was followed to minimize the monomer content of acrylic eye.[] In this technique, the flask was placed in water at 95°C × 20 min and thereafter in boiling water for additional 20 min The ocular prosthesis was acrylized, retrieved, and finished. All residual salt crystals were flushed out through the opening for the removable cap The prosthesis was tried to check for the extent, fit, comfort, and iris position. Characterization of the scleral part of the prosthesis was done with the help of (SR Adoro) light cure stains and (Targis Power) light curing unit so as to match the natural eye. Optiglaze protective coating agent (GC America) was applied to protect the characterization [] A 0.5 mm diameter exit hole for the lubricant was created on the anterior surface of the ocular prosthesis into the limbus with the help of a suitable bur which connected the reservoir containing the lubricant The prosthesis was disinfected in cidex :2% glutaraldehyde cidex (surgikos, Johnson & Johnson co.), and it was delivered to the patient with instructions as to how to load the lubricant (carboxymethylcellulose eye drops IP 0.5%, extralube).[] [Figures –]. The removable cap is to be replaced if there is deformation or tear such that it does not fit into the access passage or there is a leakage of lubricant. Patient was instructed to clean the prosthesis with ophthalmic irrigation solution.[] The chamber was cleaned by removing the removable cap and injecting ophthalmic irrigation solution through a syringe Patient was followed up after 24 h, 1 week, 1 month, 3 months, and then every 6 months. The removable cap was replaced after 6 months due to deformation.
The present case is about a 69-year-old male patient who reported to the Department of Prosthodontics with the chief complaint of difficulty in chewing food due to worn out dentures. History revealed that the patient was edentulous for past 11 years and has been using the same denture from 11 years. Both maxillary and mandibular ridges were edentulous with no bony spicules. His upper lip [] was long and inter-ridge distance was more than normal. The previous denture was with severely attrited teeth. Hence, it was decided to fabricate a new set of denture for the patient.\nAfter analyzing each available option, it was decided to fabricate hollow maxillary complete denture and conventional mandibular complete denture. The patient also approved the treatment plan as it was light in weight, inexpensive and a non-surgical procedure.
