CLINICAL ANALYSIS OF MORE THAN 130 CASES OF MAXILLARY SINUS LIFT
Abstract:
Sinus lift surgery is one of the most diverse maxillo-facial surgical procedures: there are numerous ways to approach the maxillary sinus; there is a wide variety of bone augmentation materials; may be associated with other surgical techniques preprotetics;the insertion of implants may be immediate, delayed, or late, depending on the initial bone height. The aim of this study is to demonstrate the variety of procedures and technical means, in relation to clinical outcome after sinus augmentation in 131 cases. The sinus augmentation in 131 interventions were performed on 89 patients (averagea age 49 years (24-67)). EIGHT preoperative and postoperative examination was mandatory for all patients and difficult cases were examined by computed tomography (CT). Survival of implants when evaluated after a loading integration success was compared between: different augmentation materials; smoking, nonsmoking; various postoperative complications; Immediate insertion / late implants. Time to prosthetic loading was assessed according to different groups of bone augmentation material. All 228 of screw type implants were inserted and TPS surface only in the augmented posterior maxillary sinus lift techniques. Ridge height was evaluated preoperatively between 6.59 ± 2.11 mm (4.5 and 8.5 mm). After ridge augmentation average height reached between 14.57 ± 2.33 mm (12.5 and 16.9 mm). Period prospective and retrospective study lasted 5 years and after a mean of 3.1 years (range 1-6 years) survival rate of implants was 97.2% 98.91%. We found minimal differences between the different bone grafts, and Co-morbidity associated with smoking habits. This retrospective study can be concluded that: sinus augmentation surgery is the most versatile procedure; translated by predictability and effectiveness of implant survival rate is very high and independent in relation to graft bone, surgical technique, complications, smoking and immediate or delayed insertion of implants; addition of autogenous bone mixed with alloplastic augmentation materials require less time to prosthetic loading.
