[Planning of occlusal load in designing the occlusal surface of posterior teeth based on 3D analysis]
1Central Research Institute of Dentistry and Maxillofacial Surgery, Moscow, Russia.
The Aim Of The Study:
Was to determine the possibility of calculating the parameters of the occlusal surface of fixed dentures.
Materials And Methods:
An analysis of dependence between the area of the occlusal surface and the area of the support structures (tooth root/implant), between the severity of the occlusal relief (tubercles of teeth) on the length of the root/implant was carried out.
Results:
The nearness of the Kurlandsky periodontal coefficients and Oksman masticatory coefficients with the calculated coefficients obtained on the basis of 3D analysis of the lateral teeth anatomy has been established. A method for calculating the maximum permissible vertical and lateral loads on chewing teeth is proposed.
Conclusion:
Recommendations are given on the design of the shape of the occlusal surface depending on the periodontal condition and the severity of the external thread of the implant.
