Masticatory rehabilitation following upper and lower jaw reconstruction using vascularised free fibula flap and enossal implants-19 years of experience with a comprehensive concept.

Objectives: Conventional prosthesis is generally inapplicable following reconstruction with free fibula flaps (FFF) due to impaired bone and soft tissue conditions, and rehabilitation via enossal implants in FFF is relatively novel. This retrospective study aimed to document the surgical aspects of this option and to describe related supplementary procedures that can help optimise the definitive outcome.

Material And Methods: One hundred nineteen implants were inserted within FFFs in 37 patients (mean age 51.

Comparative biomechanical study on three miniplates osteosynthesis systems for stabilisation of low condylar fractures of the mandible.

Open reduction and fixation of low condylar fractures of the mandible can be achieved by many osteosynthesis systems that differ in size, shape, and site of placement according to the surgical approach. We investigated the maximum load and rigidity of 4 osteosynthesis systems: the standard double 4-hole straight miniplates, the inverted y-miniplate (with and without self-drilling screws), and the TriLock Delta condyle trauma plate. The standard double 4-hole straight miniplate osteosynthesis achieved the best fixation and resistance in view of a mean (SD) maximum load of 539.

A new non-endoscopic intraoral approach for open reduction and internal fixation of subcondylar fractures of the mandible.

Open reduction and internal fixation (ORIF) of subcondylar fractures of the mandible is a widely accepted treatment concept aimed at reconstruction of the vertical height of the mandibular ramus and restoration of occlusion. Here, we describe new instruments designed for ORIF via an intraoral approach using a single inverted y-miniplate. The special design allows sufficient visualisation of the fracture site and enables the establishment of a standardised procedure for the treatment of both dislocated and non-dislocated fractures.

Airborne microbes in different dental environments in comparison to a public area.

Objective: The aim of this study was to investigate quantitatively and qualitatively the airborne microbial load in a multi-chair dental clinic, a normal dental practice and a non-dental public area over a time period of four days and at different time points to estimate the risk of infections during dental surgery.

Methods: A multi-chair and a single chair treatment room each were examined in comparison to a non-medical public area over a period of four days. The colony forming units m(-3) (CFUs) were determined and isolated bacteria were characterised by morphological and biochemical analysis, gas chromatography and by 16S rRNA-gene sequencing.
