目的 探讨舰船环境对人工种植牙的影响因素 ,提高其临床成功率。方法 对 2 4例舰船人员 36颗改良术式法的 HA- Ti人工种植体 ,负重 1年后进行临床及 X线随访 ,并与同期 35例陆地人员的 4 7颗种植体对照。结果 舰船组临床成功率为 86 .11% ,低于陆地组的 93.6 2 % ,统计学差异无显著性 (P>0 .0 5 )。舰船组的菌斑指数 (PL I)明显高于地面组 (P<0 .0 5 )。龈沟出血指数 (SBI)和牙周治疗需要指数 (CPITN )两项指标 ,舰船组均明显高于陆地组 (P<0 .0 5 )。两组患者种植体和牙槽骨的骨性结合率 ,舰船组 (89.6 5 %± 11.32 % )略低于陆地组 (92 .12 %± 10 .5 6 % ) ,但无明显统计学意义 (P>0 .0 5 )。结论 人工种植牙可适用于舰船人员 ,但患者应着重提高口腔及牙周保健能力。
Objective To explore the influencing factors of warship environment on artificial dental implants and to improve their clinical success rate. Methods Twenty-four HA-Ti implants with 24 modified surgical procedures were enrolled in this study. One year after loading, clinical and X-ray follow-up was performed and compared with 47 implants of 35 land-based personnel in the same period. Results The clinical success rate of the ship group was 86.11%, which was lower than that of the terrestrial group by 93.6%. There was no significant difference between the two groups (P> 0.05). The plaque index (PL I) of the ship group was significantly higher than that of the ground group (P <0.05). Gingival sulcus bleeding index (SBI) and periodontal treatment need index (CPITN) two indicators, the ship group were significantly higher than the land group (P <0.05). The bony binding rate of implant and alveolar bone in the two groups was slightly lower than that in the land group (89.6 5% ± 11.32% vs 92.12% ± 10.56%), but there was no statistical significance (P> 0.05). Conclusions Artificial dental implants can be applied to naval personnel, but patients should focus on improving oral and periodontal health care.
