Abstract

Introduction: Bone loss is one of the major difficulties faced in implantology and oral rehabilitation. Several bone graft techniques have been developed and optimized, including particulate or block, split-crest, distraction osteogenesis, among others. By the end of the 1990s, guided bone regeneration (GBR) is developed, aiming the rise of the bone reconstruction success ratio, making them more predictable. The technique consists of a barrier or membrana for bone and soft tissues separation, avoiding the fibroblasts migration into the bone matrix while it is still in the formation process. Additional techniques to enhance the graft stability were developed, such as sticky-bone. The high density PTFE (d-PTFE) barrier used in the present case report offers the possibility for oral exposure, differently from the traditional GBR, which full coverage of the membrane is required. The main advantage observed is the bigger amount of ceratinized tissue gain without compromising the healing process. The present study aims to report a case of the use of d-PTFE barrier in a bone reconstruction for alveolar preservation after tooth extraction procedure.

Case Report: female patient, 61 years old, reporting a failure during tooth extraction and resulting in the crown fracture of the element 24. Atraumatic tooth extraction was realized and the alveolar preservation with biomaterial graft associated to i-PRF and covered with d-PTFE barrier was realized. Intentionally exposed d-PTFE barrier for bone defects reconstruction in dental implant area is a promising option comparing to traditional GBR when looking for a major gain of ceratinized tissue, although new studies are encouraged in order to better define protocols and indications.
