OBJECTIVE To investigate the effect of cavity preparation on the flexural strength of heat-curing denture resin when repaired with an auto-curing resin. MATERIAL AND METHODS Ninety-six rectangular specimens (64 x 10 x 2.5 mm) prepared from heat-curing denture base resin (Meliodent) were randomly divided into four groups before repair. One group was left intact as control. Each repair specimen...

STATEMENT OF PROBLEM Hard denture acrylic resins must maintain color stability to remain esthetic. PURPOSE The purpose of this in vitro study was to measure the color stability of denture resins subjected to staining agents and cleaned with denture cleansers MATERIAL AND METHODS Forty-five disks (10-mm diameter, 2-mm thick) fabricated from 3 denture resins (light polymerized Eclipse; heat p...

Although all-ceramic restorations have become popular, they present some biomechanical problems. Some technical failures can be repaired intraorally to help maintain the longevity of the restoration. This clinical report describes an intraoral method for repairing a fractured 4-unit posterior zirconia-based ceramic fixed partial denture using fibre-reinforced composite material.

The purpose of this study was to quantitatively evaluate the effect of staining solutions by spectrophotometric method on color stability of the commercially available acrylic denture base resins polymerized by different methods of cure, materials, and immersion periods. Commercially available heat cure resin (Travelon) and self cure resin (RR repair material) were selected for the study. In ca...

Fractures of the clasp components of removable partial dentures are commonly encountered problems in the dental office. Repair or replacement procedures are therefore, often required and may be preferred over refabrication of the entire prosthesis when it is possible to maintain the denture to serve its purpose of function, esthetics and comfort after repair. This paper reviews various procedur...

The purpose of this paper is to evaluate the incidence of denture repairs in different districts of Croatia through the year of 2002. and to analyse the percentage of different repairs (relinings, simple repairs up to 2 elements and complicated repairs-more than 2 elements) in relation to prosthodontic teams. Data on the number of dentures, and the number and types of denture repairs delivered ...

The need for repairing a removable partial denture occasionally arises in clinical practice. The common causes for repair of removal partial denture include tissue changes of the residual ridge, breakage or distortion of denture components and complications that arise in the remaining teeth. Distal extension partial dentures are particularly affected as the tissue-base relationship changes over...

BACKGROUND Repeated fracture of the denture base is a common problem in prosthodontics, and it represents a nuisance and a time sink for the clinician. Therefore, the possibility of increasing repair strength using new reinforcement materials is of great interest to prosthodontists. AIM OF THE STUDY This study aimed to evaluate the effects of incorporation of zirconia nanoparticles (nano-ZrO2...

AIM The aim of this report is to describe a quick and simple method of positioning retention magnets when deformed patients are rehabilitated with an oculopalpebral prostheses attached to a maxillary denture/obturator. BACKGROUND In patients with deformities requiring complex rehabilitations, the use of magnets is the most efficient means of providing combined prostheses with retention qualit...

UNLABELLED The denture bases made by using polymethyl methacrylates of Acrylic resin family have excellent physical properties, simple to process and easy to reline, rebase and repair. One of the inherent disadvantages of this material is the liability to break during function. The strength assessment of acrylic resins have been made generally by transverse defection tests. AIM To evaluate th...
