The purpose of this study was to determine whether thermoplastic retainers need to be worn full-time for a limited period or whether part-time wear from the outset is adequate to maintain tooth position, arch form, and occlusion. This study was a randomized clinical trail, conducted in a district general hospital. Sixty-two participants were enrolled in the study. Group 1, full-time wear, consi...

Riedel (1960) recognized that after orthodontic treatment , the teeth tend to return to their original positions because the periodontal tissues have not had suf cient time to reorganize themselves. During this reorganization period , the teeth must be maintained in the position achieved orthodontically, by means of removable or  xed retention systems. When relapse is expected, a splint is of...

Objective: To evaluate the effect of deciduous teeth grinding during mixed dentition, by the control of permanent molars eruption, using contemporary MEA appliance and palatal grid for anterior open-bite treatment. Materials and Methods: The sample consisted of 31 patients with a pre-treatment mean age of 9.09 years. At the time of drawing up this manuscript, 14 patients of the entire sample re...

A method of tethering a mediator to an enzymatic membrane was studied. Glucose oxidase (GOD) and ferrocene redox polymer were immobilized in cross-linked poly (vinyl alcohol) (CLPVA) with bovine serum albumin (BSA) added as a protein stabilizer. Redox hydrogel polyallylamine ferrocene was prepared by cross-linking polyallylamine hydrochloride with glutaraldehyde and attaching the ferrocene cova...

The aim of this paper is to report a clinical case with bilateral missing mandibular second premolars that were restored by metal-ceramic inlay-retained fixed dental prostheses. The first prosthesis was of a traditional design and the second was of a modified design. The suggested design is created by modifying the retainer wings of the traditional resin-bonded inlay-retained fixed dental prost...
