Summary

Impacted mandibular third molars can cause various complications to the adjacent second molars, such as dental caries, periodontitis, or root resorption. These complications often progress silently and asymptomatically. A typical scenario involves a mesioangularly impacted third molar exerting pressure on the distal alveolar bone of the second molar, resulting in persistent food impaction that is difficult for patients to clean. Furthermore, the surgical removal of deeply impacted or severely angulated mandibular third molars often requires bone removal in the area adjacent to the second molar. These factors may exacerbate distal periodontal defects of the second molar, especially in individuals over the age of 25. This research focuses on evaluating the effectiveness of a new-generation collagen membrane in promoting healing after the extraction of impacted mandibular third molars in patients at risk of distal periodontal tissue damage to the second molars
