Abstract

Background: The full-arch restoration on 6 implants, commonly referred to as all-on-6, is increasingly proving to be an effective solution both functionally and aesthetically for patients with full-arch dental deficiencies who require restoration. However, data in this field is scarce in Vietnam. Objectives: The study aims to evaluate the effectiveness of the all-on-6 implant surgery for supporting immediate-load full-arch restorations. Materials and methods: A descriptive cross-sectional study including 24 patients with full or partial edentulism need of full-arch restoration who were assigned and agreed to undergo all-on-6 implant surgery at Ho Chi Minh city Odonto-Stomatology hospital from June 2023 to April 2024. Results: A total of 24 participants were involved in the study, with 35 arches restored (210 implants). The mean age of the participants was 67.8 ± 9.3, with a male/female ratio of 2/3. The majority of implants used were between 9.0-11.5 mm in length (58.6%) and 3.5-4.5 mm in diameter (91.0%). After implant placement and temporary restoration, all implants achieved initial stability > 30 N/cm², all patients reported no pain during mastication, and the majority were satisfied with their treatment (91.4%). Complications such as swelling, pain, bleeding, and infection were negligible. 4 months post-surgery, 34 out of 35 patients had implants with good stability, only one case had a loose implant. The proportion of mild gingivitis and bone resorption were 31.4% and 5.7%, respectively. None of the patients experienced pain while chewing. Overall, the outcomes were rated as good and fair in 68.6% and 25.7% of cases, respectively, achieving a success rate of 94.3%. No intraoperative complications occurred. Conclusion: The research demonstrates that the method of full-arch restoration with immediate-load on six implants has a high success rate, proving to be effective and safe. This makes it a suitable option for dental practitioners and patients with full-arch restoration needs.
