ABSTRACT

Background and aim: The maxillary sinus augmentation procedure is the most frequent method used to prepare the posterior maxillary area, with bone deficit, for the placement of dental implants. For this purpose, several types of materials have been used as bone grafts, each of these materials having a number of advantages and disadvantages. The present study is aimed at evaluating the histological and volumetric properties of an alloplastic and autologous material mixture.

Patients and methods: The study included 7 selected patients who underwent subantral bone augmentation with a 1/1 autologous and alloplastic material mixture. Subsequently, at the time of dental implant placement, biological samples were taken from the bone augmentation area and were histologically analyzed. The subantral bone resorption rate was also evaluated in parallel.

Results: Histological examination evidenced the presence of residual amorphous material in the bone augmentation area. The mean bone resorption rate was 15.15%. The presence of a high bone resorption rate was correlated with the presence of a smaller residual amorphous material amount in the subantral bone augmentation area.

Conclusions: The association of autologous and alloplastic material for subantral bone augmentation improves the characteristics of the two material types.

Mentions: Under local anesthesia, an incision at the level of the vertical mandibular ramus was performed, which was extended to the lower vestibule. After the mandibular cortical bone was exposed, autologous bone material was taken from the vertical mandibular ramus and the external oblique line, and the postoperative wound at the donor site was sutured with separate non-resorbable threads (Fig. 1). The autologous material was milled using a manual bone mill and then, it was mixed in a 1/1 ratio with an alloplastic material consisting of PerioGlas particles (NovaBone poducts LLC), in a 0.9% saline solution medium. The sinus cavity was lined with the material thus obtained, and the bone window was covered with a resorbable collagen membrane and the mucoperiosteal flap. A non-resorbable separate stitches suture was performed.
