Surgical intervention may lead to anatomical defects resulting in oro-antral communication that causes difficulty in mastication, deglutition, impaired speech and facial disfigurement. The role of a Prosthodontist in maxillary defects is to restore these defects with the fabrication of obturators. However, the extent of the obturator into these large defects necessitate bulkier, heavy prosthesis which would likely be nonretentive and uncomfortable for the patient. Hollow bulb obturators are fabricated to reduce the weight of these prostheses. The method of fabrication of hollow bulb obturators with lost salt technique in the maxillary defect is described in this case report.

However, in recent years, it has been observed that the majority of the removable prosthodontic treatment have been referred to consultants or at times even delegated to the technicians. One of the major reasons behind this trend may be the result of an individual graduate internal perception of their ability or lack of confidence in their ability to perform these procedures. Materials and Methods: A cross-sectional study was conducted among dental interns in People’s Dental College and Hospital, affiliated to Tribhuvan University, Kathmandu, Nepal after the ethical approval from PDCH-IRC. A self-designed validated questionnaire related to experience of individual intern and level of confidence pertaining to clinical procedures related to removable prosthesis fabrication ...

The need for maintenance to keep pace with these changes necessitates a regular follow up. However, in a developing country like ours, it is not unusual to find patients either delaying or completely avoiding these follow ups citing various reasons. Often, a new prosthesis is recommended in these situations without considering the prospect of relining and rebasing. This clinical report presents a scenario where one of these maintenance therapies was undertaken to improve the fit and function of the complete denture.

Such procedure often results in a post-surgical defect in the form of an intra oral opening. The patency of such defect, if not maintained can result in food accumulation which may lead to infection and thus delayed healing of the defect. Obturator is one of the modalities to facilitate closure of the resultant defect. This report presents a case where an acrylic plug obturator retained with clasp, was provided to the patient for the interim period following marsupialization on the mandibular left posterior region.

The presence of these displaceable denture-bearing tissues often poses difficulty during fabrication of complete dentures resulting in compromised support, retention and stability. Many impression techniques and materials have been proposed in various literatures to help overcome this difficulty. These techniques vary in philosophies but are often quite time-consuming to perform, and rely on materials not commonly in use in contemporary dental practice. The purpose of this paper is to describe an impression technique for flabby ridges, using conventional impression material.

It demands an equally sized ocular prosthesis to replace lost tissue volume. A conventional solid acrylic ocular prosthesis may be deterrent to retention and esthetics because of its weight, which can be reduced by eliminating the mass of material within it. This article attempts to present a simplified and accurate technique to fabricate a hollow ocular prosthesis using silicone putty cavity form. It is removed prior to final processing and serves to ensure appropriate uniform thickness of acrylic resin and optimal weight reduction of the definitive prosthesis without compromising mobility, esthetics, and structural integrity.

The precise reproduction of edentulous foundation is essential for retention, stability, and support of the removable prosthesis. Evidence suggests that there is variability in materials and techniques regarding impressions making for complete dentures. There is little published information on studies conducted among Nepalese Prosthodontists. The purpose of this study was to evaluate current materials and methods for impressions for complete denture prosthodontics in Nepal. Materials & Methods: A questionnaire based survey was conducted among Nepalese Prosthodontists from May 2017 to December 2017. Ethical approval for the beginning of the study was obtained via Institutional Review Committee, Nepal Medical College. A self-administered anonymous questionnaire was distributed to the participants. Data were analyzed by using frequency distribution. Results: Majority of responses indicated use of irreversible hydrocolloid in stock metal tray for making the preliminary impression. The selective pressure was the predominantly used impression philosophy (78.3%). The most common material for the fabrication of custom trays was autopolymerizing acrylic resin (96.7%). All respondents border molded the custom tray prior to making the final impression. The final impression materials used were zinc oxide eugenol impression paste (73.3%), polyvinylsiloxane (11.7%), polyether (11.7%) and polysulphide (3.3%). Conclusion: Although there is variability in impression materials and techniques used by Prosthodontists in Nepal for the fabrication of complete dentures, the results showed interesting trends. Most practitioners followed the traditional techniques of complete denture impression procedures.

Precise duplication of size and location of the iris is essential for the establishment of realism, symmetry, and a natural-appearing gaze. This article explores an alternative procedure for positioning the iris in a custom-made ocular prosthesis using a pupillary distance ruler (PD ruler). The orientation and mediolateral dimension of the iris of the natural eye was measured from the graduated scale on a PD ruler and transferred on to the sculpted scleral wax pattern. The iris button was positioned in the marked area, and the established orientation was evaluated for symmetry and a natural-appearing gaze. Accurate, predictable, and easy positioning of the iris with the transfer of these dimensions to the definitive prosthesis provided a good result in terms of patient esthetics and satisfaction.
