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

shutterstock_24547402-bridge on model

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…]

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…]

Tooth coloured adhesive filling materials are in common use in dentistry providing good results. However, their success relies on the adhesive systems that provide this bond which has allowed a more conservative approach to cavity preparation.  The aim of this review was to assess the effectiveness of these systems in non-carious cervical lesions (NCCLs).   The [read the full story…]

Limited weak evidence suggesting that flapless dental implant placement is feasible

The main aim  of this systematic review was  to quantitatively estimate the survival and success rates of immediate implants and the implant-supported prosthesis, the prevalence of biological, technical and aesthetic complications, and the magnitude of soft and hard tissue changes following implant placement in fresh extraction sockets. The MEDLINE (PubMed) and the Cochrane library databases [read the full story…]

Implant overdentures do not have a more positive effect on the nutritional state of elderly at 12 months

As teeth are lost masticatory efficiency declines and this may have a negative impact on diet which may be of particular relevance in older people.  The aim of this trial  was to assess the effects of mandibular  implant overdentures (IODs) on the nutritional status of an edentate elderly population. Participants were randomized to  receive  either  [read the full story…]
