Methods This qualitative study employed interpretive descriptive methodology and was conducted as the second phase of our previous quantitative study on patient‐reported outcomes with ILZI fixed rehabilitation. An adapted version of Pernerger's model of patient satisfaction and the patient experience framework by Oben were used as theoretical frameworks for the study. Purposive sampling with maximum variation was used to select participants from Phase 1 of the study, and others aged over 18 years with completely edentulous atrophic maxilla who had received ILZI rehabilitation. In‐depth, 40 to 60‐min face‐to‐face or telephone interviews were conducted using an interview guide until data saturation was reached. The interviews were recorded with an audio recorder and transcribed verbatim. Data analysis included transcription, debriefing, coding, thematic analysis, triangulation, and interpretation. Results Thirteen participants were interviewed (mean age, 68.2 ± 7.41 years). Drawing from the study's conceptual frameworks, four major themes were identified: <jats:italic>Tooth loss experience</jats:italic> , <jats:italic>Handling the burden of maxillary atrophy, The choice of immediate‐loaded zygomatic implant rehabilitation</jats:italic> and <jats:italic>Satisfaction with immediate‐loaded zygomatic implants</jats:italic> .

Materials and Methods Patients who were diagnosed with severe oligodontia or anodontia and treated with ZI were included. All the patients received comprehensive preoperative assessments, including radiographic imaging, genetic testing, and multidisciplinary consultations to develop customized treatment plans. The treatment strategies primarily involved extensive bone grafting combined with multiple conventional implants (CIs) and a single ZI approach or the Quad Zygoma approach. Postoperative rehabilitation involved immediate or delayed loading with provisional prostheses, followed by definitive full‐arch implant‐supported restorations. Results Twenty‐seven patients with 20 patients exhibiting syndromes, aged 18–37 years (mean age 22.63), were enrolled. A total of 85 ZIs and 42 CIs were placed in the maxilla. All the ZIs achieved successful osseointegration, yielding an early survival rate of 100%. The crude survival rates of ZIs and CIs were 98.5% (84/85) and 76.19% (32/42) at the implant level and 96.3% (26/27) and 64.71% (11/17) at the patient level, respectively, with a mean follow‐up of 55.07 months (range: 13.27–179.2 months). The main complications associated with ZIs included maxillary sinus opacification and peri‐implant soft‐tissue recession. Conclusions ZIs could be a treatment option for patients with severe oligodontia and anodontia. This study may support the feasibility and favorable outcomes of ZIs in the management of severe tooth agenesis.","PeriodicalId":10455,"journal":{"name":"Clinical Oral Implants Research","volume":"78 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148964278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
