(John Wiley & Sons Ltd., 2026-02) Schoenbaum, Todd R.; Lin, Guo-Hao; Brunello, Giulia; Strauss, Franz J.; Schwarz, Frank; Jung, Ronald E.; Wang, Hom-Lay
Objectives: To gather the opinions and preferences of experts regarding the number of implants used to support a fixed prosthesis in the edentulous maxilla, timing of implant placement, and timing of implant loading. This was performed using a single-round survey methodology. The primary objective was to support the development of a consensus and contribute to the formulation of clinical practice guidelines for the management of the edentulous maxilla.
Materials and Methods: A custom survey instrument was created by a steering committee and team of experts for the 1st Global Consensus for Clinical Guidelines. The anonymous survey was conducted using a single-round survey method. Consensus was defined as >75% and ≤95% agreement or disagreement, and strong consensus as >95% agreement or disagreement.
Results: A total of 202 experts from 42 different countries were identified and invited to participate. 117 provided consent and completed the questionnaire, resulting in a response rate of 57.9%. Strong consensus (>95%) reached on no items. Consensus (>75% and ≤95%) reached on four items: always using CBCT for planning, first molar as distal-most implant site for full-arch fixed prosthesis, use of a lab-fabricated acrylic provisional for full-arch fixed prosthesis, and the use of 4 implants to retain a removable maxillary denture.
Conclusion: This survey synthesized the preferences and opinions of experts regarding implant number, timing, and loading for the fixed rehabilitation of the edentulous maxilla to inform a consensus development process and contribute to the formulation of clinical practice guidelines for the management of the edentulous maxilla.
Patient- and Clinician-Reported Outcomes and the Outcome Measures in Studies Reporting on Rehabilitation of the Edentulous Maxilla With Implant-Supported Fixed Prosthesis Using Short, Standard-Length and/or Zygomatic Implants: A Systematic Review of Clinical Studies Published in the Last 10 Years.
(John Wiley & Sons Ltd, 2026-02) Thoma, Daniel S.; Sadilina, Sofya; Jung, Ronald E.; Park, Seung-Hyun; Park, Jin-Young; Jung, Ui-Won; Strauss, Franz J.
Objectives: To identify patient-reported outcomes (PROs), clinician-reported outcomes (ClinROs) and patient-reported outcome measures (PROMs) in studies evaluating the rehabilitation of the edentulous maxilla with implant-supported fixed prosthesis using short and/or standard-length and/or zygomatic implants.
Materials and Methods: A systematic search was conducted in MEDLINE/PubMed, EMBASE, Scopus, Web of Science, Cochrane Central Register of Controlled Trials, and National Clinical Trial Register for articles published between January 1, 2014, and March 24, 2024. Studies reporting both PROMs and ClinROs related to implant therapy in patients with fully edentulous maxillae were eligible for inclusion. Study characteristics, PROMs, and ClinROs were extracted from each article. Study quality was appraised using Cochrane's Risk of Bias 2 tool, Newcastle-Ottawa Scale, or the Joanna Briggs Institute Critical Appraisal Tool according to the study design.
Results: The electronic search identified 1981 titles after removing duplicates. Fourteen publications, reporting both ClinROs and PROMs based on 12 studies (14 publications). These studies evaluated a total of 575 participants and 3367 implants. Eight publications focused exclusively on one type of implant design: seven evaluated standard-length implants and one examined zygomatic implants. The remaining six publications assessed two implant types: four compared zygomatic and standard-length implants, while two compared short and standard-length implants. The most frequently used PROMs among the publications (n=14) were Oral Health-Related Quality-of-Life using OHIP questionnaires (7/14) and patient satisfaction using unstandardized questionnaires (7/14). The most frequently reported objective ClinROs were complication (14/14), marginal bone loss (10/14) assessed using standardized periapical radiographs, implant mobility/stability/failure (7/14), and implant survival (4/14). Subjective ClinROs related to the clinician's perception were reported in only one study (1/14) and focused on swelling after treatment.
Conclusions: PROMs and objective ClinROs are often reported together in clinical trials involving short, standard-length or zygomatic implants for implant-supported fixed prostheses in edentulous maxillae. However, the frequent use of unstandardized questionnaires for PROMs hinders sound comparisons across studies. Subjective ClinROs based on clinician perception are rarely reported.
1st Global Consensus for Clinical Guidelines for the Rehabilitation of the Edentulous Maxilla: Patient and Cross-Disciplinary Expert Single-Round Surveys
(John Wiley & Sons Ltd, 2026-02) Lin, Guo-Hao.; Brunello, Giulia; Jung, Ronald E.; Kopp, Ina; Schwarz, Frank; Wang, Hom-Lay; Strauss, Franz J.
Objectives: To gather perspectives from patients and cross-disciplinary experts on treatment practices and outcomes in managing the edentulous maxilla to inform a structured consensus process and highlight areas for future research.
Materials and Methods: An 18-item single-round survey was distributed in November 2024 with 68 patients and 68 cross-disciplinary experts. Participation was voluntary, anonymous, incentive-free, and required informed consent. Consensus was defined as >75% and ≤95% agreement or disagreement, and strong consensus as >95% agreement or disagreement.
Results: Response rates were 60.3% among patients, and 30.9% among cross-disciplinary experts. Consensus or strong consensus was achieved by patients on 15 statements across nine items and by cross-disciplinary experts on 15 statements across eight items. Items reaching consensus included the use of cone-beam computed tomography, preference for fixed full-arch prostheses, major treatment outcomes, need for hard tissue augmentation, home care regimens, dental implant lifespan, procedure difficulty, cost-effectiveness, and patient-reported outcomes. Both groups also highlighted the need for further research on full-arch implant rehabilitation of the maxilla.
Conclusion: Findings from both surveys inform the development of clinical practice guidelines in treating the edentulous maxilla by providing valuable perspectives from patients and cross-disciplinary experts. Areas lacking consensus illustrate real-world variations in treatment approaches, highlight knowledge gaps in the current literature, and reveal important differences among patient expectations, expert opinions, and available evidence.
1st Global Consensus for Clinical Guidelines for the Rehabilitation of the Edentulous Maxilla: A Single-Round Survey on Sinus Lift and Alveolar Bone Augmentation Techniques.
(John Wiley & Sons Ltd, 2026-02) Brunello, Giulia; Strauss, Franz J.; Milinkovic, Iva; Kopp, Ina; Schwarz, Frank; Wang, Hom-Lay
Objectives: The objective of this survey study was to collect expert insights on the rehabilitation of the edentulous maxilla involving adjunctive procedures such as sinus lifts and other bone augmentation techniques. This process aimed to support the development of a consensus and contribute to the formulation of clinical practice guidelines for the management of the edentulous maxilla. Materials and Methods: In preparation for the 1st Global Consensus for Clinical Guidelines for the rehabilitation of the edentulous maxilla, a structured questionnaire was developed. The survey was administered online anonymously in a single round. It consisted of multiple-choice items and 94 7-point Likert-scale statements and questions. Consensus was defined as >75% and ≤95% agreement or disagreement, and strong consensus as >95% agreement or disagreement. Results: Of the 217 experts invited from 43 countries, 116 successfully completed the questionnaire via the survey link, resulting in a response rate of 53.5%. Among the 94 statements and questions, 44 (46.8%) reached consensus and 4 (4.3%) strong consensus. All statements that achieved strong consensus pertained to key clinician-reported outcomes considered essential for inclusion in future research. There was strong agreement on the importance of evaluating surgical, prosthetic, and biological complications, along with marginal bone loss. Conclusion: This study collected valuable expert opinions to inform a consensus development process and contribute to the formulation of clinical practice guidelines for the management of the edentulous maxilla in complex cases requiring additional augmentation procedures.
1st Global Consensus for Clinical Guidelines for the Rehabilitation of the Edentulous Maxilla: Single-Round Survey on Implant-Supported Fixed and Removable Prostheses.
(John Wiley & Sons Ltd, 2026-02) Lin, Guo-Hao; Strauss, Franz J.; Brunello, Giulia; Stilwell, Charlotte; Jung, Ronald E.; Kopp, Ina; Schwarz, Frank; Wang, Hom-Lay
Objectives: This single-round survey on prosthodontic rehabilitation of the edentulous maxilla is one of four clinician surveys commissioned prior to the first Global Consensus for Clinical Guidelines (GCCG). Within the GCCG aim of refining treatment protocols and enhancing patient care, this survey gathered expert insights into best practices, challenges, and treatment outcomes for these complex restorative procedures.
Materials and Methods: The 25-item survey was sent to 230 identified experts from 41 countries in October 2024. Participation in the survey was voluntary and without incentives. Informed consent was obtained at the beginning of the survey. All data were collected, stored, and processed anonymously.
Results: Of the 230 experts contacted, 123 accessed the survey and 121 provided consent and completed the questionnaire, resulting in a response rate of 52.6%. The survey responses identified 13 statements that reached consensus (>75% but ≤ 95% agreement) and five that reached strong consensus (>95% agreement). These 18 statements were derived from 6 items addressing the topics of anatomical landmarks for tooth positioning, preferred distal implant position, preferred minimum implant diameter, preferred retention method, relevant patient-reported outcomes, and relevant clinician-reported outcomes.
Conclusion: This study gathered valuable expert insights to inform a consensus development process for establishing clinical practice guidelines for management of the edentulous maxilla. The survey identified 18 statements from six items that reached consensus or strong consensus among survey respondents. The items not achieving consensus served to reflect real-world implant treatment strategies, identify literature gaps, and highlight any inconsistencies between expert consensus and current evidence.
