Abstract

This study was designed to evaluate the clinical outcomes; success rate and peri-implant bone level change of immediately loaded implant in geriatric patients. The results were compared with those of conventionally loaded implant in geriatric patients and immediately loaded implant in adult patients. Furthermore, the peri-implant bone level of immediately loaded implants was compared over time period patients by maxilla and mandible, segments, length, type of implant prosthesis in geriatric to increase the success rate of immediately loaded implants in geriatric patients. Osstem SS-II implant and Straumann Regular implant were used in this study. The patients who visited the Korea University Anam Hospital dentistry and received implant placement were divided into 3 groups; Group A with patients over 65 and B under 65 years old who received immediately loaded implant, and Group C with the patients over 65 years old who received conventionally loaded implant. Temporary prosthesis was delivered, after abutment was set on the day of implant installation for immediately loaded implant protocol. On the other hands, second surgery was done, after cover screw was set for conventionally loaded implant protocol. Prosthodontic treatment was done after 4 months later in mandible and 6 months later in maxilla in these two protocol. Fifty six (21 males and 35 females), 149 (81 males and 68 females), and 35 (14 males and 21 females) patients were included in groups A, B, and C respectively. For groups A, B, and C, 185 (117 Straumann Regular (SR) and 68 Osstem SS-II (OS)), 413 (309 SR and 104 OS), and 170 (100 SR and 70 OS) implants were used, among which 5 (3 SR and 2 OS), 7 (3 SR and 4 OS), and 3 (1 SR and 2 OS) implants were failed. Therefore, the success rates for groups A, B, and C were 97, 98, and 98% respectively. The peri-implant bone level change was greater in group A than B (p<.05). A statistically significant difference between groups A and B for peri-implant bone level changes in 6, 12, and 24 months after implant installation. The changes between groups A and C were not significantly different.
The success rate of immediately loaded implants in geriatric patients (A) was not different from either younger group (B) or conventionally implanted group (C). After immediately loaded implants, younger age group showed more stable change in peri-implant bone level up to 24 months, however, the change in the geriatric group was stable after 6 months. Also the bone level change was not different from that observed after the conventionally implanted group in the geriatric patients. Studies longer than 24 months and on other relevant factors may be needed to use the immediately loaded implant procedure as one of the safer and predictable treatment options. Our results suggest that aging may not be a contraindication for the immediately loaded implantation.
