NVGPT Publicatieprijs 2016 voor Kostas Zygogiannis

Op 8 december 2017 reikte de NVGPT haar Publicatieprijzen 2016 uit aan mevr. Anke Korfage en dhr. Kostas Zygogiannis. Laatstgenoemde kreeg de prijs voor zijn artikel ‘Immediate loading of implants to support mandibular overdentures: A systematic review.’ Hieronder een samenvatting van zijn publicatie, waarvoor hij van prof. dr. Daniël Wismeijer van de Wetenschappelijke Commissie van de NVGPT een cheque van € 750,00 en een oorkonde kreeg overhandigd.

Different treatment protocols in terms of number, diameter and supra-structure design have been proposed for immediately loaded implants used to support mandibular overdentures. The literature review showed that several treatment protocols could lead to a successful clinical outcome. Short-term clinical and radiographic outcomes of immediately loaded Μini Dental Implants (MDIs) used for stabilization of mandibular overdentures are promising.

The concept of immediate loading of implants to support mandibular overdentures has gained popularity in the recent years. There are several treatment protocols that can be successfully applied. Although the number and diameter of the implants, and the attachment system used are important factors for the ultimate treatment outcome, the systematic review showed that there was not a specific treatment protocol that is superior. In the vast majority of the studies included in this literature review implants with a diameter higher than 3.75 mm were used. In those studies, the survival rate of standard-sized immediate loaded implants ranged from 97.7% to 100%.  In the presence of narrow crestal ridges, however, the placement of standard-sized implants in the edentulous mandible is not possible without additional surgical procedures. To overcome this limitation implants with a reduced diameter-the so called Mini Dental Implants- could be used. This protocol involves the placement of four MDIs in the interforaminal region (with or without raising a flap) and the immediate loading of them with an overdenture. The survival rates of immediately loaded MDIs varied from 90.8% to 98.3%.
In general, it was difficult to draw solid conclusions because of the heterogeneity of the selected studies and the lack of well-defined criteria. It might be concluded however, that immediate loading of dental implants to retain mandibular overdentures can provide clinical outcomes comparable to those obtained with delayed loading protocols. Mini Dental Implants have the potential to be an alternative to the current treatment modalities for the edentulous mandible.
