Psychosocial Impact of Maxilla-For-All Treatment Using Standard and Long Implants (Pterygoid, Trans-Sinus and Zygomatic) on Patients with Severe Maxillary Atrophies: A 1-Year Prospective Study with PIDAQ-23 and OHIP-14.

: The satisfaction of patients following maxillary full-arch rehabilitation is crucial in assessing treatment effectiveness. This one-year study evaluated patients' satisfaction, quality of life, and aesthetic perception after receiving the Maxilla-for-All/All-On-X treatments, which combine standard, pterygoid, trans-sinus, and zygomatic implants to support a fixed prosthesis and offer a graftless solution that reduces morbidity and treatment time. : A prospective cohort study using convenience sampling of subjects treated for severe maxillary atrophies was conducted on patients receiving immediate implant-supported full-arch fixed prostheses. The Oral Health Impact Profile (OHIP-14) and Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ-23) were administered preoperatively and one year post-treatment. Patients were grouped based on the presence or absence of complications (surgical, technical, and mechanical) and Wilcoxon tests were used for comparison (significance level = 0.05). : A total of 56 patients (29 female, 27 male) participated, with no implant or prosthesis failures. Eleven patients reported unilateral sinus membrane perforation, and seven had technical or mechanical complications. Preoperatively, 69% of patients rated their oral condition as unfavorable according to the OHIP-14; this dropped significantly to 21.8% post-treatment (-value < 0.0001). After one year, the average PIDAQ-23 score improved significantly from 44.7 ± 16.6 to 6.8 ± 5.3 (-value < 0.0001). No significant differences were observed between patients with or without complications (-values ranging from 0.5270 to 0.8920). : Full-arch rehabilitation using Maxilla-for-All/All-On-X treatments significantly improved both aesthetic perception and chewing function in patients with severe maxillary atrophies. They reported a substantial reduction in oral health-related discomfort, as shown by a significant decrease in OHIP-14 scores one year post-treatment. Clinical or technical complications did not significantly impact patients' quality-of-life outcomes or satisfaction, supporting the reliability of this treatment protocol.
