目的:探讨可调式(牙合)架在咬合重建中的应用。方法:选取临床中重度磨耗、牙齿缺失的两名患者,利用可摘一固定联合方式进行咬合重建,病例1:患者采用传统面部观察法联合普通(牙合)架行咬合记录与义齿制作;病例2:借助面弓确定上颌与髁突铰链轴的关系,通过转移台转移到可调式(牙合)架,模拟患者的口内运动,并行义齿制作。2例患者均随访2年。结果:2例患者均恢复了正常咬合,咀嚼功能得到了改善,咀嚼肌群与颞下颌关节无不适,但是病例1临床操作时间长,治疗周期长,治疗后出现因咬合导致的崩瓷、牙冠脱落等并发症。病例2临床操作时间短,治疗周期短,患者适应良好,无并发症出现。结论:通过2例临床病例的对比,利用面弓联合可调式(牙合)架进行咬合重建,可以精确模拟患者口内运动,记录咬合,提高了义齿的精确度,减少了临床调(牙合)时间与患者的就诊次数。
Objective: To investigate the application of adjustable occlusion in the reconstruction of occlusion. Methods: Two patients with moderate to severe wear and tooth loss in clinic were involved in the reconstruction by occlusal reconstruction with a removable and a fixed joint. Case 1: The patients underwent occlusal recording and denture with conventional facial observation combined with normal occlusion. Cases 2: The relationship between the upper jaw and the condylar hinge axis was confirmed by means of the facebow, transferred to the adjustable (occlusal) frame through the transfer table, simulated the patient’s mouth movement, and parallel denture production. Two patients were followed up for 2 years. Results: Both patients recovered normal bite, masticatory function was improved, masticatory muscles and temporomandibular joint were not uncomfortable, but Case 1 had long operation time and long treatment period. Crown off and other complications. Case 2 clinical operation time is short, the treatment cycle is short, the patient well-adjusted, no complications. Conclusion: The two cases of clinical contrast, the use of face bow combined with adjustable (occlusal) frame for occlusal reconstruction can accurately simulate the patient’s mouth movements, recording bite, to improve the accuracy of dentures, reducing the clinical transfer (occlusal) Time and the number of patient visits.
