Tooth size arch length discrepancy (TSALD) is a well defined means of assessing dental crowding. In previous literature conflicting evidence exists regarding the part played by tooth size and arch dimension in causing dental crowding. The objective of present study were to; examine the relationship between tooth size and arch dimension in crowded and non crowded arches, and to find out the majo...

This letter discusses the advantages and limitations of the method used in the article “A technique for registration and reorientation of surveyed dental casts” by Majid Abolhasani, Amirhosein Shakibamehr, and Hamid Neshandar Asli for recording and reproducing the cast-surveyor relation.

Background and objectives: The study was conducted with the following aims and objectives: 1. To determine and assess the extent of bilateral dentoalveolar asymmetries in long face individuals. 2. To determine and assess the skeletal asymmetry in long face individuals. Methodology: Individuals of age group 18-25 yrs as per the inclusion criteria and exclusion criteria were selected. Lateral cep...

Statement of the Problem. Fit of prosthodontic frameworks is linked to the lifetime survival of dental implants and maintenance of surrounding bone. Purpose. The purpose of this study was to evaluate and compare the precision of fit of milled one-piece Titanium fixed complete denture frameworks to that of conventional cast frameworks. Material and Methods. Fifteen casts fabricated from a single...

Cast clasps retention is essential for maintaining and stabilizing a removable partial denture (RPD). When and where this retention is inadequate, there are a series of optimization methods to use, depending on the etiology of retention faults. Dental cast clasps optimization with the purpose of increase the mechanical resistance of the removable partial dentures and their long life was studied...

The aim of this study was to compare the shear bond strengths (SBS) of cast, machined, and laser-sintered titanium to dental porcelain. Two kinds of dental porcelains (Titankeramik and Triceram) were applied on cast (Tritan), machined (DC-Titan), and laser-sintered (EOSINT) titanium specimens (n=10). SBS test was conducted, and fracture surface analysis was also performed to determine the failu...

PURPOSE To compare prefabricated and custom-made bars used for implant-retained mandibular complete overdentures. MATERIALS Ten completely edentulous patients were selected for replacement with dental implants. Each patient received 2 (press-fit) dental implants, 1 implant on each side in the canine regions of the mandible. The implants were left submerged (unloaded) for a healing osseointegr...

Binary Ti-Fe alloys with 5-25 mass% Fe were prepared, and subjected to reciprocating wear test. The aim of this study was investigate the relationship between mechanical properties resistance titanium alloys. dimensions (length, width depth) marks on less than those observed pure Ti specimen. Wear better that titanium. It established hardness main factor influenced Single β showed α+β Increase ...
