Objective: The aim of this study was to evaluate the clinical effects of fixation of bone block graft with single titanium screw adjacent to alveolar ridge crest for bone augmentation in maxillary anterior implant treatment. Methods: From 2013.01 to 2013.06, five patients with serious alveolar ridge defect in maxillary anterior zone were collected in this survey. The ages of the patients ranged from 19 to 24 with a mean age of 21.6 years old. Among them, 3 cases lost single tooth and 2 cases lost multiple teeth. Autogenous chin bone blocks were taken and fixed with single titanium screw adjacent to the alveolar ridge crests. Postoperative follow-ups were made periodically. After 6-9 months, cone beam computed tomography (CBCT) was used to evaluate their alveolar ridge augmentations and measure the width of alveolar ridges and the distance from titanium screw to alveolar ridge crest. Based on the CBCT measurements, implants were then inserted. After the osseointegration period, final prosthetic restorations were finished. Results: The successful rate of the bone augmentation was 100% and no relative clinical complications occurred in this study. Adequate bone augmentations were obtained in maxillary anterior areas and the fixed titanium screws were adjacent to the alveolar ridge crest. Conclusion: The augmentation of chin bone block graft fixed with single titanium screw adjacent to alveolar ridge crest is a predictable way to improve bone defects in maxillary anterior areas for satisfactory implant treatments.
