Abstract
BACKGROUND:
The reconstruction of the maxillary bone frequently represents a real challenge for maxillofacial surgeons especially regarding the best choice of a suitable material to produce the required bone augmentation.
AIM:
In this study, we summarize our clinical experience on 47 sinus lifts with lateral approach using a mixture of aragonitic calcium carbonate and autologous platelet-rich plasma compared with that of a previous published study in which bovine bone (LADDEC) and autologous bone were used in 50 sinus lift operations (Br J Oral Maxillofac Surg 2005;43:309-313).
MATERIALS AND METHODS:
We subjected 34 patients to sinus lift operation, for a total of 47 sinus lifts, using natural coral as osteoconductive material. This material, combined with autologous platelet-rich plasma, was placed onto the maxillary sinus floor, after carefully lifting the endosteum. Cases were clinically, radiographically, and histologically analyzed. Histomorphometrical analysis, tests of microhardness, and x-ray microanalysis were conducted comparing the various sample to controls obtained from the same patients.
RESULTS AND CONCLUSIONS:
Histomorphometrical analysis, microhardness test, and x-ray microanalysis demonstrated that the newly formed bone showed morphologic and structural characteristics that were similar for all the grafting materials compared (bovine bone, autologous bone, and coral). Although all the grafting materials did yield good results of maturation of the newly formed bone, best results were achieved using autologous bone.
