Abstract

Loss of eye can have a major psychological impact on the patient. To overcome this problem, an ocular prosthetic must have been fabricated similar with the natural eye. Various techniques are documented to determine the symme- trical bilateral iris position; these methods can be subjective and have no measurement guidelines. A 20-year-old male patient came to the Prosthodontic Clinic of Dental Hospital Universitas Sumatera Utara with the diagnosis is post enucleation socket syndrome. Determination of the iris position using the face symmetric measurement-tool by focus to the vertical and horizontal lines of the facial symmetry guide. Confirm the alignment of the vertical lines by connecting the trichion–glabella–subnasal–gnathion guide points so that they vertically divide the two sides of the face, then the two horizontal lines by connecting the left-right cheilon with the mesial-distal canthus of the right and left eyes. This tool is like a face mask with vertical and horizontal guidelines connecting the symmetrical guide points of the face accompanied by centimeters and millimetres making it easy to measure distances and sizes of the iris symmetrically. The use of this tool has given good results in determining the position of the iris because its simplicity and can see facial symmetry.

Abstract

Introduction: The disfigurement associated with the loss of an eye can cause significant physical and psychological problems. Therefore, a good ocular prosthesis is needed to restore the patient's quality of life. One of the factors that determine the quality of an ocular prosthesis is accurately impression. In the case of enucleation where the eyes socket has a soft and movable tissue bad will result inaccurate impression. The difficulty of post enuclation impression in such case is the compression of the tissue eyes socket. This case report will discuss the modification in functional impression technique using a modified custom tray. Case: A 39-year-old male patient came to Dental Hospital Universitas Sumatera Utara with chief complaint an unaesthetic and loose left stock eye that had been used for 10 years. Clinical examination shows moderate depth eye socket with soft and movable tissue. Management: The functional impression technique was modified using a self-curing clear acrylic sclera without handle as a custom tray with 2 mm reduction on the intaglio surface and light body polyvinyl siloxane as impression material. Discussion: The aim of this modification is to avoid the tendency of the eye socket to compress during impression taking and to achieve a natural contour of the eyelid convexity because of the absence of the tray handle so the patient can close their eyes. Conclusion: This technique produces an ocular prosthesis that has a good retention with excellent aesthetic result.

Abstract

Background Adhesive Bridge is a fixed denture that is attached to the tooth structure, especially the enamel, which has been etched to achieve micromechanical retention. Among other things, adhesive bridge attachment depends on, one important factor is the adhesive bond between the etched enamel and the retained metal. To increase the retention of adhesive bridges, variations of micromechanical surface treatment on metal can be carried out in the form of chemical or electrical etching, air particle abrasion (sandblasting), primary metal, tin plating, silica coating, and lasers. Objective Lasers with different energies, strengths, frequencies, wavelengths, durations and distances can create a thin layer of porous oxide which increases the bonding strength of resin cement for adhesive bridges. The role of laser power and frequency as well as the selection of the right type of resin on the metal surface of the adhesive bridge can increase the bonding strength of the resin cement on the adhesive bridge. Conclusion The selection of the type of surface treatment such as laser and the right type of resin cement can affect the bond strength of the resin cement on the adhesive bridge.
