the platform switching (pls) concept was introduced in the literature in 2005. the biological benefits and clinical effectiveness of the pls technique have been established by several studies. in this article different aspects of pls concept are discussed. crestal bone loss, biologic width, and stress distribution in this concept are comprehensively reviewed. in this article the relative publis...

BACKGROUND The rehabilitation of the atrophic posterior mandible with dental implants often requires bone augmentation procedures. The aim of the present study is the systematic review of the literature concerning the success rate of Segmental Sandwich Osteotomy (SSO) of the posterior mandible in pre-implant surgery. MATERIAL AND METHODS Systematic review of all clinical cases and clinical st...

Introdouction: Although highly desirable outcomes and longterm survival of dental implant treatments are well documented, implant failures still occur due to various reasons. Several risk factors may impair implant survival including implant dimensions (length, diameter, and implant design), procedures, local bone density at the implant site, and patient-related risk factors such as age, smokin...

In the 1960s and 1970s, implant-supported prostheses based on subperiosteal or blade implants had a poor reputation because of questionable clinical outcomes and lack of scientific documentation. The change to a scientifically sound discipline was initiated by the two scientific pioneers of modern implant dentistry, Professor P. I. Brånemark from the University of Gothenburg in Sweden and Profe...

objectives : anterior maxilla, known as the esthetic zone, plays an important role in facial and smile esthetics. this study assessed the frequency of implant treatments in the esthetic zone of patients presenting to dental implant department of tehran university during 2002-2012. materials and methods: this descriptive study was conducted on dental records of patients receiving implant treatme...

introduction juvenile ossifying fibroma is a benign, bone-forming neoplasm with aggressive local growth that is distinguished from other fibro-osseous lesions primarily by its age of onset, clinical presentation and aggressive behavior. although a benign entity, juvenile ossifying fibroma is known to be locally aggressive and has a high tendency to recur. two distinctive microscopic patterns ha...

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 purpose of this review is to explore the concept of immediate loading as it pertains to dental implants and the indications for clinical practice. The definition of immediate loading will be considered together with a review of the relevant literature in an attempt to provide evidence-based guidelines for successful implementation into practice. A search of electronic databases including Me...

PURPOSE The aim of this retrospective study was to evaluate the cumulative survival rate of tapered implant with a sandblasted and acid-etched surface placed in edentulous patients. MATERIALS AND METHODS A retrospective study was performed by evaluating MIS seven implants consecutively placed from December 2004 to January 2008. Patient records were reviewed to determine gender, age at implant...

PURPOSE This is the first study to report the clinical outcomes of photofunctionalized dental implants. MATERIALS AND METHODS This retrospective study analyzed 95 consecutive patients who received 222 untreated implants and 70 patients who received 168 photofunctionalized implants over a follow-up period of 2.5 years. Photofunctionalization was performed by treating implants with UV light for...
