Apical and lateral accuracy of intraradicular impressions made using the indirect and direct technique at three different locations: A comparative analysis.

Background: There is limited literature available comparing the accuracy of intraradicular impressions made with a novel hybrid impression material using the indirect and direct technique at three different locations.

Materials And Methods: For this comparative analysis, postspace was prepared in 15 recently extracted teeth and impressions made with vinyl polysiloxane, polyether (PE), vinyl polyether silicone (VPES), and pattern resin. Postpatterns obtained were re-seated on the teeth and longitudinally sectioned.

A Case Report on Iris Disk Positioning on a Custom-Made Ocular Prosthesis Using an Adjustable Trial Frame.

Trauma, cancer, and congenital defects may all result in the loss of an eye. This leads to significant emotional and physical challenges in an individual's life. In such cases, cautious preoperative, surgical, and prosthetic planning employing a multidisciplinary approach is essential for effective rehabilitation.

Aesthetic treatment planning simplified using digital smile design: A case report.

Digital smile design (DSD) plays an essential role in the planning of aesthetic treatments. However, most digital smile designing software programmes are expensive and require specialised training and skill for effective implementation. This paper illustrates the use of Adobe Photoshop and Microsoft PowerPoint, which are economical and user friendly for planning aesthetics in a clinical case.

Rehabilitation of an Orofacial Cleft through Presurgical Nasoalveolar Molding with a 1-year Follow-up.

Aim: To highlight the effectiveness of Presurgical Nasoalveolar Molding (PNAM) technique and the appliance used prior to the surgical reconstruction of cleft lip and palate in newborns.

Background: In underdeveloped and developing countries, babies born with oral clefts, are generally anemic with low birth weight and may be unfit for surgery immediately. Feeding these babies is also difficult as the air leaks through the cleft and they cannot create the suction needed for suckling.

Prosthetic rehabilitation of a midfacial defect with magnet-retained intraoral-extraoral combination prosthesis.

It may not be possible to treat large maxillofacial defects by surgical reconstruction alone. Prosthetic rehabilitation is invariably required to restore esthetics and function. Achieving adequate retention, stability, and support in these maxillofacial prostheses is a challenging task.

Setting And Design: study.

Material And Methods: This in vitro study was conducted on 25 discs (10mm in diameter and 2mm in thickness) using monolithic zirconia (Ceramill Zolid).

Effect of Chemical Disinfectants on the Color Stability of Maxillofacial Silicones: An In Vitro Study.

Purpose: To evaluate the effect of chemical disinfection on the color stability of room temperature vulcanizing (RTV) maxillofacial silicone elastomer with and without pigment addition.

Materials And Methods: Sixty specimens were obtained from a RTV maxillofacial silicone. The specimens were randomly divided into 6 groups according to pigments and disinfectant to be used (n = 10).

Functional Lingual Arch with Hinge-type Lockable Dentulous Component.

Unlabelled: The conventional lingual arch is a nonfunctional fixed space maintainer used in the mandibular arch to maintain arch length by the prevention of mesial movement of the permanent first molars. This study highlights a functional lingual arch with a hinge-type lockable dentulous component that incorporates molar tubes, with various advantages over the conventional lingual arch.

An innovative and simple approach to fabricate a hollow ocular prosthesis with functional lubricant reservoir: A solution to artificial eye comfort.

The loss of an eye is an emotional and psychological setback to the patient. An ocular prosthesis is created to restore the lost anatomical structure and to correct the cosmetic defect. The tear reflexes do not function at optimal levels in anophthalmic sockets which make prosthesis wear uncomfortable.

Iris Positioning Using a Grid Attached to a Spring Bow for a Custom Ocular Prosthesis.

Eyes are among the first features of the face to be noticed. Loss of an eye due to congenital, traumatic or pathologic aetiologies causes disfigurement and loss of sensory feedback. It leaves a psychological impact on the patient, thus prosthesis should be provided at the earliest to raise the spirits of the afflicted.

Shade Guide for the Fabrication of Acrylic Denture Based on Mucosal Colour.

This article highlights the use of a simple and convenient shade guide system which not only helps in choosing the shade tab that matches with the colour of the mucosa, but, also helps in the fabrication of the precise shade of acrylic resin for making the denture. The shade guide is fabricated by mixing specified quantities of various colours of acrylic polymer in order to obtain various shade tabs. The method for fabrication of the shade guide and the clinical procedure has been discussed.

The Hollow Maxillary Complete Denture: A Simple, Precise, Single-Flask Technique Using a Caramel Spacer.

The success of removable prostheses ultimately depends on a number of factors such as retention, stability, support, esthetics, and masticatory function. Increased intraoral inter-arch distance leads to an increase in the weight of the prosthesis. This may compromise the retention and resistance, which are key for a successful removable prosthesis.

Three-dimensional finite element analysis of the stress distribution pattern in a mandibular first molar tooth restored with five different restorative materials.

Introduction: Badly broken or structurally compromised posterior teeth are frequently associated with crown/root fracture. Numerous restorative materials have been used to fabricate indirect full-coverage restorations for such teeth. This study aims to evaluate and compare the effect of restorative materials on the stress distribution pattern in a mandibular first molar tooth, under varying loading conditions and to compare the stress distribution pattern in five commonly used indirect restorative materials.

Surgical excision and contoured custom made splint to treat helical keloid.

Helical keloids are difficult to treat as surgical excision requires effective compression of the operative scar to prevent recurrence while retaining the contour and elasticity of the helix. The authors fabricated a conforming custom made post-operative splint from a commonly used dental material. Splints could be fabricated in both pre-operative and post-operative stage.

Ocular prosthesis incorporating IPS e-max press scleral veneer and a literature review on non-integrated ocular prosthesis.

The article highlights a new method for the fabrication of an ocular prosthesis by the incorporation of a ceramic scleral veneer. The steps of fabrication include impression making, wax try-in, performing a "cut-back" on a selected stock eye, insertion of the IPS e-max press scleral veneer, finishing and insertion. It also includes a detailed review on non-integrated ocular prostheses.

Customized Cheek Plumper with Friction Lock Attachment for a Completely Edentulous Patient to Enhance Esthetics: A Clinical Report.

Prosthetic rehabilitation of a completely edentulous patient should never be restricted to the replacement of missing teeth. The ultimate aim of complete denture treatment should be restoration of the full range of oral functions and esthetics. Slumped cheeks are always a concern for esthetically demanding complete denture patients.

A Unique Flask Design for Processing Cranial Prosthesis Using Heat Cured Acrylic - A Case Report.

In a 30 year old male patient, the absence of a cranial bone fragment had left the brain covered only by dura mater, subcutaneous tissue and scalp, resulting in aesthetic and functional impairment. A prosthetic replica of the bone fragment made of PMMA (Polymethylmethacrylate) was fabricated using a unique flask design that consisted of a medium sized stainless steel instrument tray with lid, four large headed screws and a C clamp, since the prosthesis was too big to be invested in a conventional flask.

An Innovative and Simple Technique of Hollow Maxillary Complete Denture Fabrication.

Prosthetic rehabilitation of severely atrophic ridges has always been an ordeal for the clinician due to decreased support, stability and retention. Because of severe resorption the restorative space between maxillary and mandibular residual ridges is increased. Rehabilitation in such cases may result in increased height and weight of the prosthesis further compromising its retention and stability.
