About

Hybrid Funnel Technique arises from the union of subtractive and non-subtractive techniques for implant site preparation. Hybrid funnel technique is performed with specially designed drills and osteotome. the aim of the study is to examine marginal bone level and implant stability of implants inserted with two different techniques for the surgical implant site preparation.

Full description

Overtime several osteotomy techniques were described in literature for surgical implant site preparation and there is a clear dichotomy between expansive and ablative techniques.

The ablative techniques imply the preparation of the implant socket by removing bone: drill osteotomy and ultrasonic osteotomy. Expansive technique for osteotomy has recently been proposed: the osseodensification. Osseodensification, a non-subtractive instrumentation method, involves the use of specific drills or manual osteotomes which determine an expansion of the implant site without bone removal and bone fragments compaction on the walls of implant socket.The aim of the present study is to propose a new approach for the implant site preparation that combines ablative and expansive techniques. The technique proposed is called hybrid funnel techniqueAlthough a variety of techniques are available for implant site preparation, the hypothesis is that Hybrid Funnel technique will be positively adopted to perform osteotomy, exploiting the cancellous bone elastic properties to stabilize the implant and avoiding to stress the cortical area. Primary objectives are to compare hybrid funnel technique and traditional technique on different bone densities and to examine Marginal Bone Level torque insertion value and Implant stability.
