Intra-sinus bone evolution around implants placed using Flapless and graftless transcrestal sinus floor elevation: 3 years follow-up.

Abstract

Background: Implant placement using osteotome technique for sinus floor elevation is a widely used and discussed method. Usually, during surgery, a bone condensation procedure is used and grafting material is protruded in the preparation site in order to complete the space between sinus floor and the elevated membrane. There are studies which demonstrate good and predictable results without using bone grafting material. Meanwhile, some studies show a negative influence of the condensation procedure for the bone marrow. It is necessary to appreciate the integration process, endo sinus bone formation and its evolution around implants installed using flapless approach, without condensation and without grafting material. Aim/Hypothesis: To evaluate the intra-sinusal bone evolution around implants installed using flapless transcrestal sinus floor elevation, without bone condensation and without grafting material during 3 years follow-up.
