Study of Distracted Bone in Maxilla: A Comparative Analysis

Abstract

Introduction

Anterior maxillary distraction is one of the accepted modalities to treat hypoplastic maxilla. The study was undertaken to assess the maturation of the bone formed, which is measured by analyzing the amount of mineralization of the bone.

Materials and Methods

For the study 29 patients were chosen, who were divided into three groups. First group consist of patients who had undergone distraction osteogenesis. Second group has cleft patients and third group is the control group. A bone biopsy using trephine drill is obtained from the subjects. This sample is subjected to Fourier transform infrared spectroscopy (FTIR).

Results

From  the results a mineral to matrix ratio is obtained which is then compared between the three groups. There is a statistically significant difference between the mineralization of the three groups. The distracted bone shows the lowest mineralization while mineralization of the cleft bone is also less than the normal bone.

Conclusion

The study conclusively establishes that the distracted bone is not as mineralized as the normal bone. Although functionally the distracted bone is as good as the native bone and grafted bone as proved by the success rate of the implants placed. The study also highlights the use of FTIR for assessing the bone quality.
