Purpose. In the context of the transcrestal maxillary sinus lift a wide variety of biomaterials have been used to fill the subantral space over the years. In this study, two types of biomaterials were used in order to fill the maxillary sinus: a nanocrystallized hydroxyapatite in an aqueous solution and a micronized heterologous bone in a collagen matrix. Materials and methods. The surgical procedures were designed and carried out using computer-guided surgery. The filling volume obtained was measured with a comparative software program. Results. A ≥ 6 millimeter augmentation of osseous volume was obtained. This result is comparable to those obtained in lifts where conventional techniques were applied. The technique used was very precise and the difference between the projected and clinical outcome of the implant position had an average of less than 0.3 millimeters. Conclusions. This technique allows for the surgery to be performed in a way which is both minimally traumatic and invasive, and represents a viable alternative to those surgical techniques for crestal sinus lift currently in use.

Abstract

Purpose. In the context of the transcrestal maxillary sinus lift a wide variety of biomaterials have been used to fill the subantral space over the years. In this study, two types of biomaterials were used in order to fill the maxillary sinus: a nanocrystallized hydroxyapatite in an aqueous solution and a micronized heterologous bone in a collagen matrix. Materials and methods. The surgical procedures were designed and carried out using computer-guided surgery. The filling volume obtained was measured with a comparative software program. Results. A ≥ 6 millimeter augmentation of osseous volume was obtained. This result is comparable to those obtained in lifts where conventional techniques were applied. The technique used was very precise and the difference between the projected and clinical outcome of the implant position had an average of less than 0.3 millimeters. Conclusions. This technique allows for the surgery to be performed in a way which is both minimally traumatic and invasive, and represents a viable alternative to those surgical techniques for crestal sinus lift currently in use.
