A 60-year-old female patient reported to the Department of Prosthodontics, Vishnu Dental College, Bhimavaram, Andhra Pradesh, seeking a prosthetic replacement for the missing left eye []. The patient gave a history of surgical removal of the eye due to infection. Examination revealed evisceration of the eye with healthy intraocular tissue bed []. Upper and lower fornices had sufficient depth to provide retention for the ocular prosthesis. Hence, it was decided to fabricate a custom ocular prosthesis and a magnetic holder for the retrieval of the prosthesis after taking an informed consent from the patient.\nCustom-made ocular prosthesis is fabricated. The prosthesis was delivered to the patient and was instructed on the home care. The patient was instructed to report back after 4 weeks [] On reporting for checkup, the patient has expressed difficulty in removing the prosthesis with fingers. Hence, it was decided to incorporate a metallic disc in the prosthesis and to fabricate a magnetic holder A putty index of the tissue surface of the prosthesis was made, so that it will serve as a conformer in the later stages to maintain the contour [] A stainless steel disc of dimension 8 mm × 0.5 mm (Stainless Steel alloy 316 LVM) was placed in a prepared recess of dimension 9 mm × 2.5 mm on the tissue surface of the prosthesis in the iris region. This ensured a cover of acrylic resin with a thickness of 2 mm on the tissue surface. The thickness of resin on the external surface including the iris was 7 mm. The disc was totally embedded with acrylic resin. The contour of the tissue surface was maintained with the putty index [] After curing, the prosthesis was trimmed and polished [Figures and ] The finished prosthesis was splinted in plaster and was subjected to pressure pot curing A magnetic holder was then custom fabricated. Two cylinder-shaped neodymium magnets (Technotone Electronics, Mumbai) were enclosed in an acrylic cylinder. The magnetic holder when brought near the custom-made prosthesis attracted the metallic disc kept inside the eye shell and thus facilitated removal of the ocular prosthesis [Figures and ] The patient was trained to remove the ocular prosthesis using magnetic holder [].
A 51-year-old female patient reported to the department of Prosthodontics, with a chief complaint of looseness of both upper and lower dentures and desired the replacement of the same. Her history revealed that, she had been edentulous for 15 years and had been wearing dentures for 14 years.\nThe intra-oral examination revealed a narrow and constricted U-shaped flat palatal vault and severely resorbed maxillary and mandibular ridges []. The treatment plan decided for the patient was the fabrication of a hollow maxillary complete denture combined with neutral zone concept to enhance the retention and stability of dentures. Because of severely resorbed ridges and increased inter-ridge distance, fabrication of hollow maxillary complete denture with utilization of neutral zone concept was planned for better stability and retention.\nMaxillary and mandibular impression was made followed by border molding with green-stick (DPI Pinnacle tracing sticks, The Bombay Burmah Trading Corporation Ltd.,) and final impression with zinc oxide eugenol impression paste (DPI Impression paste, The Bombay Burmah Trading Corporation Ltd.,). Compound occlusal rims were fabricated by using modeling compound (DPI Pinnacle Impression Compound, The Bombay Burmah Trading Corporation Ltd.) mixed with greenstick (DPI Pinnacle Tracing sticks, The Bombay Burmah Trading Corporation Ltd.) in ratio of 3:7 i.e. 3 parts impression compound +7 parts greenstick compound) as per McCord's technique for making a neutral zone record by having the patient perform various Orofacial movements. Then index of this record was then made with plaster of Paris and rims were duplicated in wax. The maxilla-mandibular relationship was recorded using wax occlusal rims and transferred to the articulator and the artificial teeth were arranged. Try in procedure was done and then, all the wax excluding the wax surrounding the teeth was removed and replaced with light body elastomeric impression material (Aquasil Ultra LV Dentsply Caulk, Milford, USA). Trial denture bases were reinserted into the patient's mouth and she was instructed to perform various Orofacial movements so as to record the polished surface of the denture in harmony with the Orofacial musculature. After the try in procedure, wax up was done and dentures were made ready for processing. The mandibular denture was processed using the conventional procedures.\nThe Special Steps Taken for the Fabrication of Hollow Maxillary Complete Denture were as Follows:\nThe maxillary trial denture was flasked [] and dewaxed in the conventional manner []. Half of the heat cure PMMA (Trevalon, Dentsply India Pvt. Ltd., Gurgaon, India) in dough stage was positioned accurately over the dewaxed mould and then salt crystals were placed over it []. Above that, the remaining heat cure resin was packed and cured at 74 degree C for 7-8 hours []. Cured denture was retrieved [] and 2 holes were made in the thickest palatal area []. All the residual salt crystals were removed by flushing water with the high pressure syringe through the holes. After making sure that all the salt crystals have been removed, the escape holes were closed with autopolymerizing resin (Trevalon, Dentsply India Pvt. Ltd., Gurgaon, India) []. The hollow cavity seal was verified by immersing the denture in water, if no air bubbles are evident, an adequate seal is confirmed. The dentures were inserted in the patient's mouth [] and instructions regarding care, hygiene and maintainance were given. On 3-month follow up, the patient reported that she was quite comfortable with the dentures and she had encountered no problems.
