Purpose: The osteotome and the sinus lift are representative methods to overcome the lack of posterior maxillary alveolar bone height. But Lateral approaches are primarily recommended for lower than 5 mm bone height. The materials used in maxillary sinus lift surgery are autogenous, heterogenous, and allogenic bone. One graft material or composite graft materials are used in alveolar bone augmentation after sinus lift. In this study we are presenting cases of maxillary sinus lift surgery with each graft material to evaluate the prognosis.
Materials and methods: This analysis was performed for patients who were treated by sinus lift at Seoul National University Dental Hospital from 2003. Among 86 patients who received sinus lift, 91implants, 30 patients with a follow-up period of over 12 months after prosthesis were selected as subjects. Classification as initial alveolar bone height and graft materials was done. The change of the vertical alveolar bone height was evaluated on panoramic radiographs right before sinus lift, before prosthesis, at last follow up appointment. We evaluate bone loss of sinus graft and implant success rate.
Result: The mean follow up period is 39.8 months (12–71) and the mean decreased vertical bone height were 1.1 mm.
Conflict of interest: None declared.
