| description | [Objective:] To investigate whether the buccal fenestration approach can be effective in extracting impacted wisdom teeth in the lower mandible while preserving alveolar bone height and preventing the formation of the distal periodontal pocket of the second molar. [Methods:] A total of eighty patients with mandibular impacted lower wisdom teeth were included in the study. Patients were randomly divided into two groups. In the study group (40 patients), wisdom teeth were extracted by buccal fenestration; in the control group (40 patients), the traditional bone removal technique was used. All patients were followed up at 1 week, 12 months and 36 months after the operation. The injury of the inferior alveolar nerve was examined and recorded 1 week after the operation. After 12 and 36 months, the bone in the extraction area was evaluated by cone beam CT(CBCT). The height of the alveolar bone, the probing depth and the mobility of the adjacent second molar were recorded in the two groups respectively, and the statistical analysis was performed. The descending height of alveolar bone, whether the second molars formed deep periodontal pockets and their probing depth, whether second molars loosened and whether the injury of inferior alveolar nerve occurred were statistically analyzed. [Results:] The height of alveolar bone in the study group decreased by 1 mm on average, while the height of the alveolar bone decreased by 7 mm in the control group, and the difference between the two groups was statistically significant (P<0.05). In the study group, deep periodontal pockets were formed at the distal part of the second molars in 6 patients, and the average probing depth of deep periodontal pockets was 4.5 mm at 12 months after the operation and 5 mm at 36 months after the operation; in the control group, thirty‐two patients developed deep periodontal pockets with an average probing depth of 7.5 mm at 12 months after the operation and 8 mm at 36 months after the operation, and the difference between the two groups was statistically significant (P<0.05). No second molar loosening was found in the study group; in the control group, there were 30 patients with second molar loosening about degreeⅠat 12 months after the operation and 32 patients at 36 months after the operation, and the difference between the two groups was statistically significant (P<0.05). Four patients suffered from the injury of inferior alveolar nerve after the operation and recovered within 6 months in the study group; three patients suffered from the injury of inferior alveolar nerve after the operation and recovered within 6 months in the control group, while the difference between the two groups was not significant (P>0.05). [Conclusion:] Buccal fenestration can effectively preserve the height of alveolar bone in the extraction area and reduce the incidence of distal periodontal pockets of the second molar. At the same time, it doesn't increase the complication such as the injury of inferior alveolar nerve. It's one of the ideal methods to extract the impacted lower wisdom teeth. |
