Wound healing has been and remains an important topic in dentistry and other medical fields. Biomaterials proved to be beneficial in the process of wound healing. They can be derived from nature or synthesized in the laboratory using a variety of chemical approaches. 

Countless efforts have been made to find new and specific bioactive additives that promote and accelerate healing, regulate the inflammation and improve regeneration. The impact of these so called ‘platelet concentrates’ has been explored in sports medicine and orthopedics. By facilitating recruitment, proliferation and maturation of cells participating in regeneration, platelet concentrates clearly improve wound healing. Whereas the first generation of platelet concentrates (‘Platelet Rich Plasma’ products), were very expensive and came with a very difficult preparation protocol, the second generation of platelet concentrates (Platelet Rich Fibrin) seems to have partially overcome this problem. Nevertheless, literature is at times contradictory on the benefits of these platelet concentrates and the obtained data are often difficult to interpret. 

This lecture will focus on L-PRF as a surgical additive. Its preparation protocol and usefulness during various oral surgical procedures will be carefully highlighted in view of the current evidence. Shortcomings will be addressed.


Prof. Dr. Andy Timmerman


Prof. Dr. Andy Temmerman graduated, cum laude, as a dentist (DDS) in 2007 at the University of Ghent in Belgium. In the same year he started the post-graduate education in Periodontology at the Catholic University of Leuven in Belgium.


In 2010, he graduated as an ‘EFP certified’ periodontologist (MSc).

Since 2009, he works in a private clinic (ParoPlus, Aalst). This clinic focusses totally on periodontology and implant dentistry


In May 2017, he defended his PhD thesis entitled: “Impaired Bone Quality & Quantity and Oral Implants: An evaluation of Treatment Strategies”.


In 2018, he was appointed Associate Professor at the Department of Periodontology, having an educational undergraduate task in head/neck anatomy and a postgraduate educational task in periodontology and implant dentistry.


Prof. Dr. Temmerman frequently lectures nationally and internationally.

He is (co-)author of 30+ scientific papers in peer-reviewed journals and several Chapters in textbooks.

In 2015 he received the price for “Best Abstract” during the EAO-meeting in Rome. In 2016,

he received the price for best presentation during the EAO-meeting Stockholm.


His research focusses on CADCAM augmentation procedures, optimizing surgical techniques and various other topics in oral implantology and periodontology.


He is part of the educational committee of the EAO (European Association for Osseointegration), part of the educational committee of the BVP (Belgian Society for Periodontology), treasurer of the BVOI (Belgian Society for Oral Implantology), ITI fellow and study club director for ITI Flanders.
