Rehabilitation of acquired mandibular defect with two-piece, magnet-retained salivary reservoir.

Resection of large tumors involving mandible is the most common reason for mandibulectomy in patients. Adjunct therapies complicate the clinical situation and advocates innovations in conventional design concepts and treatment protocols. Xerostomia is one of the most common complications arising post-radiotherapy. Incorporation of a salivary reservoir in the design has been frequently used in xerostomia patients using acrylic dentures. The purpose of the article is to highlight a technique and steps in rehabilitation of a large acquired mandibular defect using a two-piece, magnet-retained acrylic removable partial denture with salivary reservoir.

Custom-fabricated nasal conformers and surgical stents in the management of midfacial acid burn injuries: A clinical report.

Acid burn injuries in the midfacial region cause contracture of the skin and nasal aperture, which can lead to nasal airway obstruction. Management of such complicated situations requires a multidisciplinary approach, including prosthetic intervention. This article describes a clinical treatment for fabricating a custom nasal conformer for a 28-year-old man who presented with a history of an acid burn injury leading to obstructed external nares and fusion of the tip and columella of the nose with the philtrum of the upper lip. The prosthesis served the dual function of maintaining the nasal airway passage and preventing the contracture of the graft placed over the upper lip during reconstructive surgery.

Utility versus futility of facebow in the fabrication of complete dentures: A systematic review.

AIM: The aim of this review was to investigate utility or futility of facebow for fabrication of complete denture prosthesis to maximise clinical efficiency and acceptability of complete dentures. SETTINGS AND DESIGN: Systematic review following PRISMA guidelines. MATERIALS AND METHODS: A study question was designed based on PICOT model which was used to evaluate whether facebow transfer is required or not for fabrication of complete denture prosthesis. An extensive search was carried out manually and using electronic databases such as PubMed-Medline, Cochrane, Google Scholar, and Clinicaltrials.gov. Parameters under review included patient satisfaction, masticatory efficiency, occlusal adjustments, clinician time, stability and retention. Boolean operators, MeSH terms and limiters were applied to develop the search and reach to conclusive studies pertaining to study design. Literature dated between 1950 and 2019 were selected. The data extraction and assessment of the studies was done by two independent investigators. STATISTICAL ANALYSIS USED: No meta-analysis was conducted due to heterogeneity of data obtained. RESULTS: 13690 studies were shortlisted, 13672 were excluded based on title and abstract. By the end of search phase, 07 RCTs were considered relevant. 04 studies concluded comparable/ no differences in outcome with and without use of facebow for fabrication of complete denture prostheses, whereas 03 studies concluded better results without the use of facebow. CONCLUSION: The use of facebow results in fabrication of complete denture prostheses with similar results in terms of clinical efficiency and patient acceptability as compared to simplified techniques using anatomical landmarks. Variations in assessment criteria, non uniform distribution of sample size amongst different clinical trials and subjective questionnaire based criteria are the weaker links in the review. Extensive research and long term standardised studies with objective criteria for assessment are required for comprehensive and conclusive results to establish the need for change in clinical practice.
