Comparing the Morphological Accuracy of Two Modified Seal Methods Assisted Resin (Occlusal) Veneer Restoration of Posterior Teeth
Objective: To compare the morphological accuracy of the modified silicone seal method and the modified resin seal method in assisted resin (occlusal) veneer restoration of posterior teeth. Methods: 80 patients who were admitted to our hospital from January 2023 to June 2025 and required posterior teeth resin (occlusal) veneer repair were selected and divided into a silicone seal group and a resin seal group using a random number table method, with 40 cases in each group. The silicone seal group used the modified silicone seal method to assist repair, and the resin seal group used the improved resin seal method to assist repair. The indicators related to the accuracy of the restoration shape and the treatment effect were compared between the two groups. Results: The edge suitability, occlusal contact accuracy and morphological matching scores of the restorations in the silicone seal group were all higher than those in the resin seal group, while the restoration detachment rate and edge microleakage incidence were lower than those in the resin seal group (p < 0.05). Conclusion: The improved silicone seal method has better morphological accuracy in assisting posterior tooth resin (occlusal) veneer repair, can reduce the risk of adverse events after repair, and has higher clinical application value.
