Guided bone regeneration with polypropylene membrane – histological analysis

Introduction: One of the main purposes in Oral Implantology for bone regeneration is to maintain or to improve the height and thickness of alveolar bone after tooth extraction as well as to avoid the connective tissue migration through the remaining bone, which is known to reduce the amount of bone at this place.

Objectives: This paper introduces a non resorbable polypropylene membrane used in guided bone regeneration surgeries. This barrier is intentionally exposed to the oral cavity and has to be maintained in position for two weeks after tooth extraction since its installation, mainly in alveolar sockets with vestibular loss in teeth indicated to be extracted. The membrane allows the alveolar socket to be full filled with the blood clot and works as a barrier to the gingival tissue ingrowth, avoiding the use of grafts and biomaterials to fill the remaining alveolar bone. The surgical technique is simple, safe and predictable, intending the regeneration of both: bone and epithelial tissue.

Purpose: The purpose of this paper is to show the viability of this material by clinical evidences and histological analysis using light microscopy.

Conflict of interest: None declared.
