Abstract:

Objective The masticatory efficiency of patients in different periods was evaluated by three methods of recording jaw relations in complete denture replacement. Methods This randomized self-controlled trial included 20 patients, who were subjected to complete denture replacement. Direct interocclusal records, Gothic arch tracing, and combination of Gothic arch tracing and face bow transfer were used. These methods were carried out to evaluate masticatory efficiency after immediately wearing the denture(before occlusal grinding) and three months after occlusal grinding. Results For patients immediately wearing dentures, the masticatory efficiency by combination of Gothic arch tracing and face bow transfer was significantly higher than the other two methods, and the difference was statistically significant(P<0.05). Direct interocclusal records and Gothic arch tracing methods exhibited no statistically significant difference. The masticatory efficiency three months after occlusal grinding by the three methods showed no significant difference. Conclusion The combination of Gothic arch and face bow transfer improved the patient’s masticatory efficiency immediately, the efficiency of doctors, and the satisfaction of patients.

Key words: complete dentures, Gothic arch, masticatory efficiency, face bow
