Abstract: Abstract: Objective To study the clinical effects and operation designs of aesthetic implantation surgery in cases of maxillary central incisor lost with insufficient vertical alveolar bone height. Methods 25 patients with maxillary central incisors loss were placed with 34 ITI implants. The cases of insufficient bone were implanted with Bio-Oss artificial bone and covered with Bio-Gide absorbable biological film in maxillary edentulous ridges. Superior restorations were completed 3-6 months subsequently. All cases were followed up for 6-12 months. Results All the 34 implants in 25 patients were all firm, without obvious discomfort. Short-term implantation success rate was 100%. In the follow-up, gingival loss occurred to 1 patient. Patients’ satisfaction rate of clinical effects was 96%. Conclusion In case of maxillary central incisor loss with insufficient alveolar bone height, different surgical methods should be chosen according to the widths of alveolar ridges. Also the GBR technique should be adopted to rebuild adequate alveolar bone, make sure of the implantation success rate, and satisfy patients’ aesthetic requirements.
