Introduction: The cranio-mandibulary syndromes are pathological entities in which at least one of the components of the dento-maxillary apparatus (jaws) is not structurally or functionally adapted to its own activity. These disorders include manifestations at the temporomandibular joint or neuro-muscular system and occlusal disarmony manifested in the dento-periodontal component of the dento-maxillary apparatus. Unfavorable occlusal relations causes changes to the fundamental positions of the mandible, resulting in non-physiological forces exerting a negative impact on the periodontium manifested clinically and radiologically through: dental mobility, gingival retraction, periodontal bags, widening of the desmodontal space. Aim of study: The purpose of this study was to identify periodontal signs produced by occlusal trauma and to remove potentially harmful periodontium factors by obtaining a mandibular-maxillary relationship that maintains the health of the dentomaxillary apparatus. Materials and methods: The study based on the clinical, paraclinical and dental treatment of the patients included in the study group was performed. A group of 20 persons with at least one of the following signs considered to be inherited from cranio-mandibulary disorder: dental mobility, pathogenic dental wear, root resorption, widening of the desmodontal space, Stielmann cracks, occlusal parapuncture (bruxism), hypercementhosis, false or true periodontal pockets. Results: During the study, we were able to highlight that primary or secondary occlusal trauma is a cofactor in the production of periodontal disease. In the absence of microbial plaque, occlusal trauma, does not produce gingivitis or periodontitis, and minor periodontal lesions are reversible. Conclusions: Occlusive trauma occurs when one or more teeth are harmful to excess strain, by intensity, duration, frequency, direction. Occlusal trauma is a cofactor in the production of periodontal disease; therefore, treatment should begin early by correctly identifying the causes of occlusal disharmony and removing them
