Aim: based on occlusion and temporomandibular health indicators, to improve clinical effectiveness of dental orthopedic treatment of patients with a need for a full mouth reconstruction.
Materials and methods. A total of 647 patients with adentia and a need for a full mouth reconstruction received comprehensive examination and treatment. Patients were divided into 3 groups. Group 1 (n=218) was exposed to standard treatment procedures. Group 2 (n=195) received certain elements of the interdisciplinary approach to dental orthopedic rehabilitation. Group 3 (n=234) was exposed to interdisciplinary approach towards dental orthopedic rehabilitation. The follow-up period was 7 years. A key step in the treatment of group 3 patients was to conduct full patient examinations sequentially. The corresponding procedures were supplemented with tests for temporomandibular disorder and occlusal relationships. In treatment planning, the cause-and-effect relationships between this disorder and malocclusion were identified.
Results. It was found that the use of the present proposal contributes to the normalization of occlusion. For instance, the occlusal index dropped 2.1-fold (relative to that in the comparison groups). The frequency of ICP manifestations decreased by 2.1 to 4.3 times, the protrusion frequency decreased by 12.2 to 22.3 times, and the bruxism frequency became 4.8 to 5.2 times lower. Furthermore, the frequency of left and right mediotrusion detection dropped by 3.2—4.3 and 3.8—4.4 times, respectively. The revealed changes were persistent, and a positive effect maintained throughout the follow-up.
Conclusion. The interdisciplinary approach to the restoration of the anatomical shape of teeth should involve the assessment and correction of occlusal disturbances.
