Lecture: “Augmentation procedures of soft and hard tissues using biomaterials – predictable in the daily practice”


A lecture by Daniel Rothamel


One of the most challenging procedures in dental implantology is the predictable and safe regeneration of bone and soft tissue defects. Although autogenous bone is still considered being the golden standard, different biomaterials such as bone substitutes and membranes have shown predictable results in augmentation procedures of the alveolar process. Whereas the regeneration of smaller defects inside the ridge contour may be supported by transmembraneous angioselectivity of the applied membranes, extended defects require volume-stable bone substitute materials and long-lasting barriers. Native porcine pericardium has shown favourable results, based on its multi-layered collagen structure. Moreover, available bone substitutes differ significantly in terms of biochemical aspects, influencing the volume stability, speed of bone formation, graft remodelling and patient´s acceptance. Also the quality of the recipient site, the osteogenicity of the graft and the selected healing time are affecting the predictability of the regeneration outcome.

In addition to bone augmentation biomaterials, specific collagen matrices have been established for soft tissue augmentation procedures, including gingiva thickening, vestibuloplasty and recession coverage. In contrast to the patient´s own soft tissue, the use of biomaterials is not accompanied by donor site morbidity.


This presentation will detail selection rules of different collagen matrices and different bone graft materials that fit to the indication, the defect´s shape and to the patient’s preconditions in order to achieve the best regeneration outcome. Based on clinical examples new treatment options of prevalent clinical indications like socket preservation that arise from the availability of novel collagen soft tissue grafts will be presented.

Daniel Rothamel is a graduate of the Heinrich-Heine University of Duesseldorf, Germany, and received his Dr. med. dent. with the thesis “Establishing a new method for quantification of tooth hypersensitivity”. He was trained in oral surgery and also obtained the Dr. med with his thesis on “Biocompatibility, biodegradation and angiogenetic aspects of native and cross-linked collagen membranes”. From 2002-2007 he worked as a Research Associate at the Department of Oral Surgery (Prof. Dr. J. Becker) at the Heinrich-Heine University in Duesseldorf, Germany. In 2005, he volunteered at the Clinic of Plastic and Reconstructive Surgery in Sankhu, Kathmandu, Nepal before he went in 2007 to Australia to start a post-doc position at the Department of Oral Pathology and Molecular Research, Westmead Hospital, University of Sydney, Australia (granted by DAAD). In 2008, Daniel Rothamel moved back to Germany to work as a Research Associate in the Department of Oral and Maxillofacial Plastic Surgery (Prof. Dr.Dr. J. Zoeller), University of Cologne, Germany and received his PhD on “Reconstruction of jaw defects using artificial and autogenous bone blocks in combination with growth factors”. Daniel Rothamel is best known for his research interest in guided bone regeneration, implant surfaces, collagen membranes, bone substitute materials, and growth factors.
