Objective: Introduction: In modern dental prosthetic practice, there often occur inconsistencies of occlusion in oral cavity and on cast dental models, leading to search for a solution to the problem of improving the registration accuracy of occlusal relationships of dentitions. The aim: Clinical laboratory study of bite registration materials selected efficiency.
Patients and methods: Materials and methods: Examination of 10 patients was conducted. Registration biomaterials: Consiflex, Аluwaх, Futar D were successively placed on occlusal surfaces of each patient. After polymerization of registration materials, determination of biometric deviation of markers from complementary position in the regions of dentitions under study was performed. Clinical measurements of BDM values were performed with an accuracy of ±0,01 mm.
Results: Results: During clinical examination using Futar D, BDM index in the region of teeth 16-46 reached (0,055±0,05) mm, 26-36 - (0,065±0,05) mm, 13-44 - (0,075±0,04) mm, 23-34 - (0,075±0,06) mm, 21-31 - (0,015±0,02) mm. In case of using aluwax, BDM index in teeth 16-46 was (0,075±0,04) mm, 26-36 - (0,11±0,07) mm, 13-44 - (0,08±0,04) mm, 23-34 - (0,09±0,07) mm, 21-31 - (0,02±0,03) mm. Application of Consiflex demonstrated BDM index in teeth 16-46 was (0,075±0,06) mm, 26-36 - (0,11±0,07) mm, 13-44 - (0,13±0,06) mm, 23-34 - (0,14±0,07) mm,21-31 - (0,045±0,04) mm.
Conclusion: Conclusions: Clinical and laboratory research with the use of Futar D registration materials in patients with intact dentitions demonstrated lower optimum of differences between BDM indices in comparison with Consiflex and Aluwax.
