ABSTRACT
INTRODUCTION: Different surgical procedures have been proposed to achieve successful horizontal ridge reconstruction of the anterior maxilla, most of these procedures require complex surgical stages with morbidity and are time-consuming.
AIM: The purpose of this study is to evaluate the efficacy of using a customized xenograft shell with a 1:1 mixture of particulates xenograft and autogenous bone for the reconstruction of horizontally deficient anterior maxillary alveolar ridges.
METHODS: Cone beam computed tomography (CBCT) images of the atrophic maxilla of eight patients were acquired and generated into 3D models. The data were transferred to a 3D printer and solid models were fabricated. During the surgery, the xenograft blocks were manually sliced and customized on the 3D printed models and fixed then the gap was augmented with a 1:1 xenograft autograft mixture.
RESULTS: Clinical assessment showed no adverse effects. However, one patient exhibited wound dehiscence. The mean difference between the preoperative and the six months postoperative showed a net average bone gain by 4.06 mm at 2 mm from the crest and 4.34 mm at 5 mm from the crest, which was statistically significant. On the other hand, a statistically significant graft resorption by 1.41 mm and 2.19 mm at 2 and 5 mm from the crest was found when the mean difference between the immediate and the six months postoperative was calculated.
CONCLUSIONS: Within the limitations of the study, the use of xenograft shells as a barrier for maxillary alveolar ridge reconstruction is predictable technique however, further investigations regarding the required time for graft consolidation is required.
