Evaluation of Vertical Discrepancies in Crown Seating Using Different Glass Ionomer Cement Volume: An In Vitro Study.

Background This in vitro study aimed to assess the vertical disparities in the positioning of complete crown castings when different quantities of cement were used and to determine the optimal amount of cement for cementation while minimizing any marginal discrepancies. Methodology A total of 60 ideal nickel-chromium (Ni-Cr) crown castings were divided into three groups of experimental volumes of glass ionomer cement, with 20 castings in each group. Group I had completely filled volume with cement, group II had it half-filled, and group III had brushed up cement internally.

Effect of the Use of Die Lubricant on the Marginal Fit of Wax Patterns.

Unlabelled: The aim of this study was to evaluate the effect of die lubricant on the fit of wax patterns. An ivorine tooth was prepared to receive full-coverage metal-ceramic restoration with 360° shoulder finish line. The tooth was duplicated 40 times using additional silicone.

Prosthetic Rehabilitation of a Nasomaxillary Defect Utilizing a two-Component Prosthesis: a Clinical Report.

Nasomaxillary defects may affect patients' speech, mastication, swallowing, breathing, quality of life, psychology, and social behavior. A combination of surgical reconstruction and prosthetic rehabilitation is frequently required to restore optimal function and esthetics. Of particular concern are the size, weight and contour of the prosthesis, as they can drastically affect comfort, retention, masticatory function and ease of insertion and removal.

All about Dowels - A Review Part I. Considerations before Cementation.

The optimal way of restoring a non vital tooth with dowel-core technique has long been a controversial matter. The purpose of this review was to assess the factors that may influence the successful restoration of root filled teeth with root canal dowels. The first part of the review discusses indications and physical parameters of dowel.

Complete occlusal rehabilitation of patient with radiation caries - a case report.

One of the most distressing and dramatic causes of xerostomia is radiotherapy for the cure of maxillofacial and neck carcinomas. Patient with radiotherapy induced xerostomia presents with challenges in prosthodontic management and in unique radiation caries control. This clinical report illustrates step by step execution of complex treatment planning that lead to successful outcome in 34-year-old man, who had been treated with Radical Neck Dissection (RND) and therapeutic radiotherapy for squamous cell carcinoma of tongue and due to radiation caries, was presented with chief complaint of difficulty in mastication.

The use of newer high translucency zirconia in aesthetic zone.

Loss of anterior tooth causes aesthetic and functional disharmony. Although no restorative material can approach the appearance of intact tooth enamel, glass ceramic, at the increased risk of brittle fracture, can mimic original tooth color better than the other restorative options. The newest zirconia material comes with unparalleled individualization in aesthetics and optimal physical properties.

Epidemiological Study to Evaluate the Prevalence of Dentine Hypersensitivity among Patients.

Background: Dentine hypersensitivity (DH) is a common finding with different prevalence rate. The aim of this study was to evaluate the prevalence of DH and associated risk factors.

Materials & Methods: This cross-sectional survey was done among patients coming to dental hospital.

Comparative evaluation of shear compressive bond strength between cross-linked acrylic resin denture base and cross-linked acrylic resin teeth with different modifcations of their ridge lap surfaces.

A major problem commonly observed in denture wearer is the detachment of artifcial tooth/teeth from acrylic denture base. The problem was grave when porcelain teeth used along with the then available denture base materials. The bond formed was purely mechanical and hence debonding of teeth from denture base was a frequent occurrence.
