The aims: Evaluation of interrelations between the type of periodontal and the response from mechanical local factors including tooth-periodontal joint for orthodontic restoration.
Material and methods: The clinical cases presented are represented by patients aged between 8 and 16 years treated at Orthodontics and Periodontal Clinics at U.M.F. Craiova for eruption perturbation that affected periodontal status. Patients were both evaluated: clinical and complementary (digital images of intra-oral status, models for study and OLeary index for calculus).
Results and Discussions: Evaluation of interrelations between the type of periodontal and the response from mechanical local factors including tooth-periodontal joint for orthodontic restoration. 4 clinical situations were established and analysed: palatal eruption for 12 with gingival mucosal fibrosis make difficult orthodontic restoration and 13 in vestibular eruption with thin periodontal level is predisposing to gingival recession; the presence in vestibular window of 13 at eruption process are generating gingival recession at a thin periodontal status; frontal incongruent teeth-alveolar at mandible are involving an in-equal distribution of periodontal structure with fibrosis and a lower dimension for mucosa keratinisation area, that are involving a difficulty for naturally oral hygienic status; presence of over-number teeth with appearance out of dental alveolar ridge generating disharmony at teeth-alveolar level by incongruence are involving an inn equally deficiency of periodontal structure.
Conclusions: The dental eruption at the ridge level is the key-factor that are involving determination of level of tissues keratinisation rounded teeth, the thickness of osseous tissue that are involving the periodontal design growing at marginally areas with both consequences: periodontal and orthodontics.
