Abstract:

BACKGROUND: Studies have demonstrated the maxillary sinus mucosa has an ability to promote bone formation, and over time, new bone can be formed in the space between the maxillary sinus intima and implant.

OBJECTIVE: To compare the effect of opening sinus lifting and internal sinus lifting for immediate dental implantation without bone transplantation and to detect the survival of dental implants.
METHODS: Fifty patients with insufficient bone in the maxillary posterior area were collected to undergo maxillary sinus lifting with simultaneous dental implantation without bone transplantation, and randomly divided into two groups, 25 in opening sinus lifting group and 35 in internal sinus lifting group.
RESULTS AND CONCLUSION: After a 12-month follow-up, 59 implants functioned normally, and 1 implant was loose after opening sinus lifting. The operative time and the amount of bleeding were significantly lower in the internal sinus lifting group than the opening sinus lifting (P < 0.05), but there was no difference in the short-term stability (postoperative 12 months) between the two groups (P > 0.05). Twelve months after operation, the bone mass around the implant was significantly less in the opening sinus lifting group than the internal sinus lifting group (P < 0.05). These findings indicate that maxillary sinus lifting techniques with simultaneous implants but without bone transplantation is feasible, which is characterized as simple operation process and less cost, but long-term stability needs further observation.
