Implant therapy is becoming the treatment of choice for the replacement of teeth in partially edentulous arches. The interim phase of implant treatment often presents particular problems because of the position of the remaining teeth, their periodontal status, and the loss of vertical dimension of occlusion. This case report will discuss the design and fabrication of a cast bar reinforced long-...

CASE REPORTS The problem of thermal sensitivity following non-surgical root-canal treatment is explored and case reports are presented. Possible causes for post-treatment discomfort from endodontic and restorative aetiologies are discussed, as are the mechanisms to explain the patients' painful experiences. Treatment of this problem may vary from the simple replacement of a defective restoratio...

objective: repair of an indirect restoration is usually preferred over its replacement. this study aimed to evaluate the effect of silane in different surface preparation techniques on the bond strength of direct to indirect composite resin.   methods: for this in vitro experimental study, 48 indirect composite cubes were fabricated, divided into 4 groups of 12 and subjected to the following pr...

For a proper functional restoration of the knee following knee arthroplasty, a comprehensive understanding of bony and soft tissue structures and their effects on biomechanics of the individual patient is essential. If the joint surface is altered due to arthritis, fracture or alloplastic knee surface replacement, knee biomechanics may be disturbed [Sharma2012, Delport2012]. Otherwise, if the l...

today power consumption is considered to be one of the important issues. therefore, its reduction plays a considerable role in developing systems. previous studies have shown that approximately 50% of total power consumption is used in cache memories. there is a direct relationship between power consumption and replacement quantity made in cache. the less the number of replacements is, the less...

external costs of environmental degradation are often ignored in economic analysis of projects. the mail goal of the paper is to economically analyze the current alternatives of meighan wetland utilization including extraction of sodium sulfate, aquaculture of artemia and integrative alternative considering external costs of wetland degradation. in order to detect eventual degradation of wetlan...

The restoration problem for Poissonian images, arising in medical and astronomical applications, is an active research area. The associated optimization models are quite challenging since the fidelity term of the problem is not a quadratic function and the regularizer is usually nonsmooth. Recently, the augmented Lagrangian-based alternating direction method has been proposed to solve the total...

Three treatment options exist for the replacement of congenitally missing lateral incisors: canine substitution, a tooth-supported restoration, or a single-tooth implant. Selecting the appropriate treatment option depends on the malocclusion, the anterior relationship, specific space requirements, and the condition of the adjacent teeth. The ideal treatment is the most conservative alternative ...

METHODS: Sixteen patients (10 women and 6 men) with a mean age of 35 years (ranging from 21 to 49 years old) were treated from 2004 to 2005 for single-tooth replacement in the upper arch. The patients were randomly divided into two groups: in the test group patients received implants placed and restored (non-occlusal loading) at the time of tooth extraction; in the control group implants were p...

The functional and aesthetic restoration of teeth compromised due to aggressive periodontitis presents numerous challenges for the clinician. Horizontal bone loss and soft tissue destruction resulting from periodontitis can impede implant placement and the regeneration of an aesthetically pleasing gingival smile line, often requiring bone augmentation and mucogingival surgery, respectively. Con...
