An Assessment of the Efficacy of Sinus Balloon Technique on Transcrestal Maxillary Sinus Floor Elevation Surgery


the invasiveness of modified Caldwell-Luc (lateral approach) and the drawbacks of the osteotome (summers'technique) in maxillary sinus floor elevation surgery.Materials and methods: A total of 13 adult Iraqi patients aged 28-55 years, 4 males and 9 females underwent sinusfloor elevation surgery via crestal approach by using sinus balloon technique. A panoramic radiograph and (Conebeam computed tomography (CBCT)/or medical CT scan) were obtained before and after surgery. Postoperativegained bone was assessed and the patient reactions including pain, nasal bleeding, and ecchymosis wererecorded. The whole follow up period was 1year following the sinus lift surgery.Results:The total performed sinus floor elevation cases were 17 with a total of 27 sinus floor elevation sites. Themaximum gained bone with sinus balloon technique was 10.6 mm. Twenty three dental implants placed inaugmented maxillary sinuses, two implants early failed 8.70 % and the survival rate of the dental implants was (91.30%). Schneider's membrane perforation didn’t occur in any case of this study 0%.Conclusion: Sinus floor elevation via crestal approach using the balloon technique solve the limitations for originalosteotome technique (summers' technique) for cases even when the subantral bone height is less than 3 mm. Theutilization of hydraulic pressure in combination with balloon technique also shows a great role in both sinusmembrane elevation and as a diagnostic aid of Schneider's membrane perforation
