This study was performed to make comparative analysis of the clinical findings between the two different types of the implant-assisted removable partial dentures: removable partial dentures using implant surveyed bridge as an abutment (ISBRPD) and overdenture type of removable partial denture using implant attachment (IARPD). Implant cumulative survival rate, marginal bone resorption, probing d...

INTRODUCTION The aim of this prospective clinical study was to cephalometrically investigate the dentoalveolar and skeletal changes produced by a removable appliance with palatal crib associated with high-pull chincup therapy in children with Angle Class I anterior open-bite malocclusions. METHODS Thirty children with initial mean age of 8.61 years and mean anterior open bite of 4.01 mm were ...

OBJECTIVES To identify the retention protocols practiced by orthodontists in Saudi Arabia, and the factors affecting retainer choice.  METHODS This cross-sectional study took place between February and March of 2015 at the College of Dentistry, University of Dammam, Dammam, Saudi Arabia. A previously tested electronic survey of 34 items was sent to all 1,200 orthodontic members of the Saudi O...

For patients with shortened dental arches, many treatment options are available. The existing situation can be maintained by stabilizing the present dentition and improving the occlusion without extending the arch. Alternatively, the shortened dental arch can be extended by either a free-end saddle removable partial denture, cantilevered fixed bridge, or by an implant-supported prosthesis. The ...

INTRODUCTION Phonetic adaptation is a complex biological phenomenon with a highly individual course, depending on the patient's motivation to use prosthesis, on the functional quality of removable dentures. The aim of the study was to estimate phonetic adaptation in patients with partial dentures, connecting it to alteration in speech quality and dentures functional value. MATERIALS AND METHO...

Objective: To assess and compare the type of complications during Herbst treatment with Cantilever Bite Jumper (CBJ) and removable mandibular splint. Methods: Twenty one consecutive Herbst patients treated with the CBJ were compared with twenty one consecutively treated Herbst patients with stainless steel crowns on the maxillary first molars and a removable mandibular acrylic splint. The initi...

OBJECTIVES 1. - To measure the alveolar resorption processes that occur in patients wearing mandibular overdentures on 2 implants and fully-removable maxillary dentures, and to evaluate the same process on patients wearing fully-removable dentures on both arches. 2.- To verify whether Kelly's Combination Syndrome occurs in the group of patients wearing overdentures. METHOD AND MATERIAL Forty ...

Background: The purpose of this study is to reveal the relationship between mild cognitive impairment and oral function by investigating an epidemiologic survey of independent elderly people who wear removable dentures. Materials and methods: 250 people who were at least 65 years and wore removable dentures were ultimately analyzed. Subject’s oral function was investigated using dental prescale...

Multi-unit parallel production systems (MuPPSs) widely exist in many industry areas. A general requirement for the MuPPS is that each system should continuously run and its downtime be as short feasible. For such systems, optimising preventive maintenance (PM) policy crucial so resources number of spare units repairmen can optimally used. On this basis, paper develops an optimal model jointly P...

Our object is to give an overview of some basic results about holomorphic mappings of circular domains in various spaces of operators. We begin by considering C*-algebras and pass to J*-algebras and other spaces when this seems natural. Our first result is a simple extension of the maximum principle where the unitary operators play the role of the unit circle. We illustrate the power of this re...
