Abstract

Subperiosteal implants (SIs) were first developed by Dahl in 1941 for oral rehabilitation in case of severe jaw atrophy. Over time, this technique was abandoned due to the high success rate of endosseous implants. The emergence of patient-specific implants and modern dentistry allowed a revisitation of this 80-year-old concept resulting in a novel "high-tech" SI implant. This study evaluates the clinical outcomes in forty patients after maxillary rehabilitation with an additively manufactured subperiosteal jaw implant (AMSJI®). The oral health impact profile-14 (OHIP-14) and numerical rating (NRS) scale were used to assess patient satisfaction and evaluate oral health. In total, fifteen men (mean age: 64.62 years, SD ± 6.75 years) and twenty-five women (mean age: 65.24 years, SD ± 6.77 years) were included, with a mean follow-up time of 917 days (SD ± 306.89 days) after AMSJI installation. Patients reported a mean OHIP-14 of 4.20 (SD ± 7.10) and a mean overall satisfaction based on the NRS of 52.25 (SD ± 4.00). Prosthetic rehabilitation was achieved in all patients. AMSJI is a valuable treatment option for patients with extreme jaw atrophy. Patients enjoy treatment benefits resulting in high patient satisfaction rates and impact on oral health.

Visual representation of the distribution of the data set of the OHIP-14 and NRS score. (Left): The boxplot of the OHIP-14 values ranges from 0 (first quartile) to 5 (third quartile). Median value is 2 and interquartile range is 5. Minimal and maximal values were, respectively, 0 and 40, with 40, 17, 14, and 13 being the outliers. (Right): The boxplot of the NRS values ranges from 50 (first quartile) to 54.75 (third quartile). Median value is 52 and interquartile range is 4.75. Minimal and maximal values were, respectively, 42 and 60, with 42 being the only outlier.
