Abstract
Objective:To investigate the effect of osteotome sinus floor elevation using sinustech reamer in the cases with residual bone high deficiency in maxillary posterior areas.Methods:Nineteen cases(29 teeth)were received sinus lift with the application of sinustech reamer.The height of sinus membrane lift was less than 2 mm in every placement.Twenty-nine implants were placed without bone grafts and the height of the apical part implant that entered the sinus was less than 2 mm.An immediate CT scan was followed to perform a thorough examination on every placement.The implants were restored after 3~4 months.All the patients were followed up for 5 years to evaluate the effect with clinical examination and CT scan. Results:No damage or laceration of the sinus membrane was observed in 29 placements.None of the cases occurred inflam-mation of maxillary sinus.The alveolar bones were well osteointegrated with 29 implants after 3~4 months.There was no ob-vious bone absorption around the implants after 5-year follow-up.The tips of the implants were surrounded by new recon-struced cortical bone of maxillary sinus floor.All the implants were well functional.Conclusion:The technique of osteotome sinus floor elevation using sinustech reamer with satisfactory therapeutic effect and high success rate,and could be used in the maxillary posterior area implant placement with residual bone high deficiency.关键词
