The use of geistlich mucograft seal and geistlich bio-oss membranes in the post-exodontial alveolar sealing clinical case report

The loss of tissue after a tooth extraction is a physiological process and is more pronounced during the first 3 to 6 months after extraction, followed by great reabsorption throughout the patient’s life, both horizontal and vertical.1–3 The chronological sequence of the biological events that occur during alveolar healing results in reabsorption of the alveolar crest.4 The dental extraction initiates a series of repair processes involving hard tissue (alveolar bone) and soft tissues (periodontal ligament and gingiva). It occurs filling the alveolus with blood clot, then by a slow process of remodeling that results in the formation of new bone inside it.5 Healing of the alveolus is characterized by internal and external changes. When waiting for the natural time of healing can occur the formation of bone within the alveolus, even with this condition, alveolar process is lost in height and width.6 Alveolar preservation is a procedure performed to minimize alveolar resorption and increase bone formation at the extraction site.1‒9 Adequate bone volume is required to provide satisfactory esthetics and positive results over a long period of time after the installation of osseointegrated implants.3 The simple placement of the graft material into the extraction cavity significantly reduces the size changes of the alveolar bone.9 It is possible to preserve the alveolar bone crest with the filling of biomaterials, as bone substitutes and, also, membranes for the formation of a barrier of the material grafted with the buccal cavity, obtaining great results in the cicatrization.4,8 The placement of bone substitutes into the fresh alveolus may have a positive effect on healing and prevents atrophy of the alveolar bone.3 The purpose of this study was to evaluate the membrane, Geistlich Mucograft Seal®, used for the post-extraction alveolar sealing together with Geistlich Bio-Oss®.
