ADA-EBD critical summary – survival of various tooth- or implant-supported restorations

shutterstock_85691464

This new critical summary from the ADA-EBD Center for evidence-based dentistry looks at a 2012 review from Pjetursson et al  which set out  to assess and compare the 5- and 10-year survival of different types of tooth-supported and implant-supported fixed dental prostheses (FDPs) and single crowns (SCs), and to describe the incidence of biological and [read the full story…]

Limited evidence to compare survival of metal ceramic with porcelain-fused-to-zirconia single crowns

shutterstock_85731241

Crowning of teeth has been carried out for many years in order to replace damaged/diseased tooth structure or to improve aesthetics.  Increasing patient demand has helped lead developments in ceramic technology and zirconium is one of the new materials in this field. The aim of this study was to compare the clinical survival rates of [read the full story…]

Review suggests that radiotherapy was associated with higher rates of implant loss

Implant–supported restorations show good success rates in healthy tissues while studies in irradiated jaws contrasting outcomes have been reported. The aim of this review was 
to assess the survival rate of titanium implants placed in irradiated jaws. The Medline, Embase, and CENTRAL, and  OpenGRAY databases were searched together with a number of journals (Clinical Implant [read the full story…]

ADA-EBD summary on short dental implants

This critical summary form the American –Dental Association-Centre for Evidence-based Dentistry looks at a 2011 review by Sun et al . The commentator feels that there was a lack of focus to the question under consideration and that the search strategy was limited. There were also some concerns about  whether the potential for publication had [read the full story…]

Evidence of small benefit in peri-implant bone loss seen in first 5 years with platform switching

Cross section of a dental implant

This critical summary from the American Dental Association – Evidence-based Center (ADA-EBD) looks at a 2010 systematic review from Atieh et al. The aim of the review was to assess whether platform switching  (the placement of a smaller diameter prosthetic component on a larger diameter implant fixture) improved survival rate and bone loss. The commentator [read the full story…]

Some limited evidence that patients with previous periodontal disease at higher risk of dental implant failure

Dental implants are now widely used to replace missing teeth and periodontal disease is an important cause of tooth loss.  As implants themselves can suffer from peri-implantitis  it is therefore of interest to as to whether patients with a history of periodontitis are of higher risk of implant failure.  This critical appraisal of a 2010 [read the full story…]

Limited randomized clinical trial evidence on the survival of dental small-diameter Implants

Endosseous root form dental implants have been available since the 1960s while dental Small-Diameter Implants were first introduced commercially in the dental field in 1990. The aim of this study was to determine, the survival of narrow diameter implants, whether survival is dependent on whether these implants are placed using a flap or flapless approach, [read the full story…]

Short term data suggest zirconia-based fixed dental prostheses may be an alternative to metal ceramic prostheses

Zirconia is a polycrystalline ceramic without a glassy phase and exists in several forms. Recently, zirconia has been used to fabricate ceramic fixed dental prosthesis FDPs with relatively high strength and good aesthetics.  The aim of this systematic review was to assess zirconia-based FDPs in terms of survival and complications. Veneering techniques for porcelain application [read the full story…]

Glass fibre-reinforced posts performed better at 5 years in endodontically treated teeth

Post systems are used in the restoration of endodontically treated teeth where there has been significant loss of the clinical crown. A post provides a method to secure filing material to the tooth.  The aim of this trial was to  assess the survival rate of two different post systems after 5 years of service. Patients [read the full story…]

Partial loss of teeth – so many treatment options – but insufficient evidence to recommend best method

Logo of The Cochrane Collaboration

The management of patents who present with the partial loss of teeth is a common task for dentists and has been so for many years. The aim of this Cochrane review is to assess the effects of different prostheses for the treatment of partially absent dentition in terms of the following outcomes: long-term success, function, [read the full story…]
