目的评估应用游离龈瓣移植加宽种植体颊侧角化黏膜临床效果。方法 8例患者共植入14颗种植体,种植二期时种植体颊侧龈缘中点处角化黏膜宽度均小于2mm,共进行8例游离龈瓣移植,游离龈瓣均取自硬腭。结果 8例移植龈瓣均成活。术前种植体颊侧龈缘中点处角化黏膜宽度0~1.5mm,平均0.32±0.64mm。游离龈瓣移植后复诊时间2~9个月,平均4.50±2.33个月。复诊时种植体颊侧龈缘中点处角化粘膜宽度2~8mm,平均4.29±1.82mm。结论游离龈瓣移植可有效加宽种植体颊侧角化黏膜。
Objective To evaluate the clinical effect of free gingival flap transplantation on implant buccal keratomileusis. Methods A total of 14 implants were implanted in 8 patients. The width of the keratoconjunctival mucosa at the midpoint of the buccal gingival margin was less than 2 mm at the second stage of implantation. A total of 8 cases of free gingival flap were transplanted. The free gingival flap was taken from the hard palate. Results 8 cases of gingival flap all survived. Preoperative implant buccal gingival margin at the midpoint of keratinized mucosa width of 0 ~ 1.5mm, an average of 0.32 ± 0.64mm. Free gingival flap transplantation time after referral 2 to 9 months, an average of 4.50 ± 2.33 months. At the time of referral, the width of keratinized mucosa at buccal gingival margin was 2 ~ 8mm, with an average of 4.29 ± 1.82mm. Conclusion Free gingival flap transplantation can effectively broaden the implant buccal keratosis mucosa.
