Bilayered ceramic anterior restorations with reinforcement of the incisal edge by using lithium disilicate: A multicenter retrospective survival analysis with a maximum of 6-year follow-up.

Statement Of Problem: The esthetics of anterior lithium disilicate restorations can be enhanced if the buccal aspect is layered with a feldspathic ceramic. However, whether fractures and chipping of this layer are a prevalent complication is unclear.

Purpose: The purpose of this retrospective study was to evaluate the incidence of incisal fracture of a specially designed lithium disilicate reinforcement of the incisal edge for indirect anterior bilayered restorations on both teeth and implants.

Immediate implant placement and provisionalisation in the aesthetic zone.

The aim of this retrospective study was to assess the outcome of immediate single-tooth implant placement and provisionalisation in the aesthetic zone regarding hard and soft peri-implant tissue parameters and patient-related outcome measures in a private practice. All consecutively treated patients with single-tooth immediate implant placement and provisionalisation between the period 1 January 2006 and 1 April 2013 in a referral practice in Amsterdam, the Netherlands, were included in the study. Fifty-one patients of a total of 64 could be examined at follow-up (Tfollow-up ).

[Listeria mastitis in cattle].

Cases of human infection caused by Listeria and resulting from the consumption of dairy produce contaminated by Listeria are referred to in the literature. A case of mastitis in cattle, caused by Listeria monocytogenes type 1/2a, is reported. The result of treatment of the infected quarters with penicillin was not satisfactory so far.
