Abstract: Objective: This study is aimed to investigate the single-tooth implant restoration in maxillary aes-thetic zone with narrow gap. Methods: This study did the implant surgery in a minimally invasive flapless way. And the permanent restoration was performed with an all-ceramic crown 4 months after the implant surgery. The restoration took the advantage of the teeth disorder to restore the gap with the cover of the dis-order to make up the narrow gap and disproportion between the teeth. Results: The color and the shape of the crown were in coordination with the natural teeth. And healthy pink aesthetics and proper white aes-thetics enhanced the whole facial aesthetic effect. The treatment effect was beyond expectation and the patient left with great satisfaction. Conclusion: The implant restoration in this study can meet both the functional and aesthetic demand of the patients with narrow gap in maxillary aesthetic zone which is sig-nificant in clinical therapy to some degree.
