The assessment of rehabilitation methods in patients with severe upper jaw atrophy

Abstract

Introduction. Insufficient bone volume is difficult to manage in rehabilitating patients with maxillary atrophy. The currently available solutions are: • increasing the bone amount followed by standard implantation • the alternative method by using zygomatic implants without preimplantation bone growth. Purpose. Comparative evaluation of standard versus alternative methods of rehabilitation in patients with severe maxillary atrophy. Material and methods. Study was axed on 12 patients, aged 32 - 67 years, mean age 54.5 years, divided into 2 groups. Patients in group I (7) were rehabilitated by zygomatic implants without bone grafting, and patients in group 2 (5) were rehabilitated by bone grafting, with delayed implantation. Patient data was processed in Sidexis 4.2 and Microsoft Excel. Results. In group I, 4.42 implants / patient were used, 1 intervention was performed under general anesthesia, 1 under local anesthesia with intravenous sedation and 5 under local anesthesia only. The patients underwent a single surgery with an average duration of 134 minutes and the functional rehabilitation of the patients lasted an average of 6.28 days. In group II, 8.4 implants / patient were used, all 5 bone grafting procedures were performed under general anesthesia, and subsequent interventions were performed under local anesthesia, the average summary time of surgery was 385 minutes. The functional rehabilitation lasted on average 12.8 months. Conclusions. The study demonstrated the effectiveness of both methods, but showed that the alternative rehabilitation method can be performed in a shorter time, with a smaller number of implants, mostly under local anesthesia, in a single surgery with a shorter duration.
