Abstract

The polypropylene membrane was developed to be used immediately after tooth extraction in order to protect the clot of the cervical region of the alveolus in the alveolar's bone height preservation direction during the repair. She works as a short period physical barrier (7 to 10 days postoperatively) and can remain exposed to the oral medium without the need to flap and loss of tractor gum inserted. The objective of this work is to evaluate the polypropylene membrane's performance in the preservation of alveolar's post-extraction volume. The criteria for inclusion in the study will be patients with good systemic conditions that need to extract two or more front or back teeth belonging to the same arc. For the definition of which tooth will belong to the control group and the experimental group, will be done to study randomization. The dental elements will be extracted by conventional methods of a dental extraction in accordance with each indication. In the control group after surgery for extraction, the plot will be filled only by a clot. In the experimental group after extraction polypropylene membrane will be installed. These patients will be subjected to radiographic and tomographic exams, to evaluate the height of the bone crest. Such information will be subjected to statistical tests, to evaluate the percentage of alveolar volume preservation with the use of polypropylene membranes.
