[Endosseous integrated implantation: multiple post-extraction implantationing threaded cyclindric titanium. Use of a semipermeable reabsorbable membrane].
On the basis of their experience of postextractive oral grafts, the authors examine all the surgical possibilities of this technique, at times using osteoinducing materials or at others semipermeable reabsorbable membrane; on other occasions an ostroinducing material associated with reabsorbable membrane is used to stimulate piloted regeneration of underlying bone tissue. Although not widely used, the post-extractive technique is presented as a fascinating reality that certainly, if used with due care, produces satisfactory and gratifying results. The authors are convinced that the contribution to simplifying surgical procedures and the reduced number of sessions that a patient has to undergo is without doubt a considerable advantage. In fact, using the postextractive technique with reabsorbable membrane the patient only undergoes a single operation. The authors have experience of three hundred post-extractive grafts with a very low failure rate (loss of seven grafts). These results can be attributed to clear rules: respect for antisepsis precautions, minimum surgery involving bone tissue, design of access flap to bone arch, positioning of fixture in correct spatial and occlusal direction, instant graft stability and perioplantar bone neoformation free of interference. The use of grafts has become a routine technique and is a valid alternative to prosthetic rehabilitation stages. It has become a true field with precise characteristics in the context of modern dentistry.
