Crowns improved survival of root treated teeth suggests review

shutterstock_17046487

This technology review looked at the effectiveness of crowns on root treated teeth. 3 systematic reviews and 4 non-randomised studies were included. They found that the short term survival with crowns or direct fillings is comparable but long term root canal treated teeth may have better survival.

This review compared the survival of mandibular overdentures supported by 1- or 2- implants. Only two small RCTs were identified that suggest no difference between 1- or 2- implants. However only a small number of patients were included in these trials so the evidence is weak and more high quality trials are required.

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…]

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.
