OBJECTIVE The aim was to answer the clinical research question: is incisal/occlusal tooth wear assessment on dental casts performed by five professionals with expertise in different fields of dentistry reliable? METHOD AND MATERIALS Five examiners with different fields of expertise in the dental profession assessed tooth wear on dental casts of 45 subjects, based on a six-degree rating of inc...

BACKGROUND Angulated implants may result in inaccurate impressions, and the impression technique may affect the accuracy of the definitive cast. This study was designed to compare the dimensional accuracy of casts obtained from three impression techniques for three definitive lower casts with implants at different angulations. METHODS Three Osseolink implants were placed in three reference mo...

STATEMENT OF PROBLEM Accurate recording of implant locations is required so that definitive restorations are properly supported and do not place additional stress on the implants. Angulated implants may result in inaccurate impressions, and the impression technique may affect the accuracy of the definitive cast. PURPOSE The purpose of this study was to determine the effect the combined intera...

BACKGROUND This study evaluated the survival of the most prevalent oral bacteria and fungi (Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli, and Candida albicans) in dental casts, and compared changes in the amounts of these microorganisms at different time intervals to determine how long dental casts may pose threat to the health of dental personnel and patients. MATERIAL AND ...

Technical advances in 3D morphometrics and other forms of digital analysis allow for detailed measurements dental metrics yet, consistently, anthropologists show a publishing preference using calipers. It is possible that this reflects the often complex field settings, wide global distribution sample collections, or simple fact calipers are relatively low maintenance cost technology. Similarly,...

The aim of this investigation was to examine the effect of pre-term birth on sagittal occlusal relationships. The subjects were 328 prematurely born white and black children and 1804 control children who participated in the cross-sectional study of the Collaborative Perinatal Project (USA) in the early 1960s and 1970s. Dental examinations, including dental casts and photographs, were performed ...

Casts with a high surface hardness and abrasion resistance are essential for conventional dental prosthesis construction procedures. The water/powder ratio is critical factor determining the physical chemical properties of gypsum casts, any modification to this may alter these properties.

Chemical cleansing by denture cleansers is the first choice for denture plaque control of tissue conditioners. This study evaluated the influences of denture cleansers on the surface quality of tissue conditioners by determining surface roughness and porosity. Three tissue conditioners (Hydro-Cast, SR-Ivoseal, Visco-Gel) and 3 types of denture cleansers (Pika [enzyme type], Polident [neutral pe...

Acrylic processing of waxed-up dentures is considered to be a crucial and technique-sensitive procedure. Polymethylmethacrylate (PMMA) has become the most commonly used material for denture bases since its introduction in 1937. The advantages of PMMA include excellent esthetic properties, adequate strength, low water sorption, low solubility, lack of toxicity, facility of repair, and constructi...

The purpose of this study was to compare maxillary canine retraction with sliding mechanics and a Ricketts canine retraction spring, using a midpalatal orthodontic implant as a measuring reference. Eight patients (three males and five females) were examined. Because maximum posterior anchorage was required in all subjects, osseointegrated midpalatal implants were used. To examine tooth movement...
