3D GBR using PTFE non-resorbable membranes in the aesthetic zone


Implant treatment on the aesthetic zone aims for healthy, functional and also aesthetic results. In order to obtain an aesthetic result it is mandatory that the implants are placed in optimal 3D position and completely surrounded by healthy bone.  

A harmonious and healthy status of the soft tissues is also a pre-requisite of an aesthetic result. 

Due to the alveolar ridge destruction caused by trauma and dental or implant infections, bone availability is often not ideal to obtain a good aesthetic result.  In order to treat such cases predictably there are surgical techniques that allow a complete 3D reconstruction of the alveolar ridge. 

When an implant is malpositioned on the aesthetic zone, it is more susceptible to develop biological (periimplantitis) and aesthetic failures. If a malpositioned implant is infected, the implant should not be treated, since although bone can be regenerated, the new bone is highly susceptible to new bone resorption because an important part of the etiology of the problem is the wrong implant position (especially too labial and too deep). In such cases, extraction of the implant and 3D bone regeneration of the resulting defect is desirable in order to place a new implant in optimal 3D position so a highly aesthetic restoration may be achieved. Furthermore, for an optimal aesthetic result,  periodontal plastic techniques have also to be performed.

All these topics will be addressed in this lecture.

Learning Objectives

  • To understand 3D bone regeneration techniques: GBR using PTFE and Ti reinforced membranes and Khoury's Technique.
  • To understand the regenerative techniques needed to treat aesthetic and biological implant failure in the aesthetic zone.


Dr David González obtained his PhD degree (Doctor in Odontology) at the University Complutense of Madrid achieving a qualification of “Summa cum Laude”, presenting the Doctoral Thesis “Risk Factors of Periodontal Disease” in 1999.

David studied a 3-year full time postgraduate program in Periodontology at the University Complutense of Madrid (directed by Dr Mariano Sanz) between 1996 and 1999. He also completed his studies regarding dental implants with a Specialty in Osseointegration at the University Complutense of Madrid (also directed by Dr Mariano Sanz) in 1999-2000. 

David is the author of the Book “Atlas of Plastic and Regenerative Implant Surgery on the Esthetic Zone” (IN SPANISH) printed by Editorial Quintessence. He has been a Specialist Member of the Spanish Society of Periodontology and Osseointegration since 2000 and the European Federation of Periodontology. He was a Professor in the General Dental Council of Spain from 2004 to 2012.

David is a visiting Professor  of the P|ostgraduate Program of Periodontology in the University of Barcelona (since 2003). He has publications in the Journal of Clinical Periodontology, The International Journal of Esthetic Dentistry, JOMI and in Clinical Oral Implants Research.

He has lectured about periodontology and implant dentistry specifically on bone regeneration and soft tissue management worldwide.

Since 2005  David has run a private practice dedicated exclusively to periodontology and implantology  in Murcia, Spain (Clínica OrtoPerio).
