目的探讨球帽附着体固位的覆盖义齿在下颌无牙颌患者的应用效果。方法为21位下颌牙槽嵴严重萎缩的患者在下颌骨前牙区共植入41枚种植体,3个月后,用球帽附着体固位的覆盖义齿修复,分别在种植术后3,6和12个月采用临床检查和X线观察,评价义齿的固位、稳定性和咀嚼功能。结果球帽附着体覆盖义齿修复后经1～2年观察,所有种植体与骨组织结合良好,球帽附着体固位的覆盖义齿能显著提高下颌全口义齿的固位和稳定性,明显改善咀嚼功能。义齿稳定、咀嚼功能良好,患者满意。结论临床上利用球帽附着体固位的种植覆盖义齿能较好改善下颌全口义齿功能。
Objective To investigate the effect of overdenture with ball cap attachment on mandibular edentulous patients. Methods Twenty-one patients with severe atrophy of mandibular alveolar crest were implanted with 41 implants in anterior mandibular anterior region. Three months later, the implants were fixed with ball cap attachment. The implants were implanted in 3, 6 and 12 months using clinical examination and X-ray observation, evaluation of denture retention, stability and chewing function. Results After 1 to 2 years of rehabilitating the ball cap attachment, all the implants and bone tissue were well bonded. The overdenture with ball cap attachment retention could significantly improve the retention and stability of the mandibular complete denture and improve significantly Chewing function. Denture stable, good chewing function, patient satisfaction. Conclusion Implants covered with cap attachment can improve the function of mandibular complete denture.
