Orofaciodigital syndromes (OFD) are rare genetical disorders characterized by malformations of the mouth (oris), face (facies), hands and feet (digitus = finger, toe). It is still impossible to fully understand the whole spectrum of all dysfunctions due to OFD, since the expressions of the syndrome vary in each patient. There are various alterations, thoroughly described in literature that can affect the oral cavity such as dental caries, abnormal teeth, enamel hypoplasia, supernumerary teeth and dental agenesis...

The aim of this meta-analysis was to verify the clinical viability of single implant-retained mandibular overdentures (SIMO). An electronic search of the PubMed and Cochrane databases was performed (end date July 2017); this was supplemented by a manual search of the literature. Only prospective clinical trials and randomized controlled trials (RCTs) that evaluated SIMO with a minimum follow-up of 12 months were included. The meta-analysis was based on the Mantel-Haenszel method. Dental implant and prosthetic failure were the dichotomous outcome measures; these were evaluated through the risk ratio (RR) and odds ratio (OR), with corresponding 95% confidence intervals (CI)...

Poor stability of a complete denture is a common problem due to bone atrophy of the edentulous ridge. The aim of the present study was to analyze denture stability after receiving implants and to study the biomechanical properties of denture implants and the bone bed using conventional or mini implants. Five models based on computed tomography (CT) data of edentulous patients were created. The overdentures' connection to the implants was assured by means of ball head abutments and rubber rings. In three models, the denture was supported by two to four conventional implants and in two models, the overdenture was supported by three to five mini implants...

With careful restorative planning and surgical placement, dental implants can be used to support and retain a wide range of esthetic prostheses. When implant planning or surgical executions are less than ideal, however, the resulting restorative space can be a significant obstacle to successful treatment. The aim of this article is to describe the use of a customized anterior bar to support a partial overdenture prosthesis for a youthful patient with a high smile line and a limited restorative space of 6 mm...

The concept of a two-implant overdenture as the minimum standard of care or first choice treatment for the edentulous mandible was first proposed in 2002 and has since been backed by an overwhelming body of evidence supporting greater patient satisfaction and improved quality of life. This article examines the implant overdenture concept and its various options and discusses best practice from both the patient's and a medico-legal standpoint.
