Here is another manifestation indicating occlusal issues: the frequent loosening of a prosthetic piece (dental crown or bridge).
As a matter of fact, irrespective of the retention means and the lamination of the piece, if our realization is well designed, its position will be perfectly reinforced by the stabilization provided simultaneously by the proximal contacts and by the occlusal contacts. After each closing, the prosthetic piece will be in the most favorable position with its support.
But some interferences in laterality or propulsion may still occur, which may detach the prosthetic piece from its support. The dentist should always check all parameters and proceed to final cementing only when the stabilization of the prosthesis is ensured.
If it’s not the case, dental migrations, periodontal injuries or even worse, coronal or root fractures may occur. If all these elements resist, then temporo-mandibular disorders may develop. This aspect justifies a temporary cementing of the prosthetic parts and, if possible, an immediate detection of this type of disruption, to correct it before definitive cementing.
Occlusal disorders may cause various diseases, which will be discussed later in this blog. These pathologies are as follows:
dental diseases (dental migrations, tooth wear, mylolysis, loosening, pulp hyperemia)
diseases in relation with the individual’s overall balance (headaches, dizziness, backache, eye problems, tonic postural system problems, psychological diseases associated with craniomandibular disorders)
