Abstract:

Scope: The scope of this clinical and paraclinical study was to assess the condition and subsequently the improvement of the periodontal status by orthodontic uprighting of the II year molars affected by mesial tipping. This phenomenon occurs after early M I edentation, in case of fine periodontal biotype or in case of pathological events suffered by the support tissue.
Material and method: The study was carried out on a group of 26 patients, aged between 26 and 35 years, who had their 3.6 and 4.6 teeth extracted for various reasons, in whom M2 was turned and affected by mesial tipping. Further to the periodontal examination, we found on the mesial interface of M II a 3-4 mm thick marginal periodontal ligament (in 21 cases, that is 80.7% of the whole study group). The X-ray examinations revealed the extension of the periodontal space and bone resorption in the interproximal mesial space.
The fixed orthodontic treatment consisted of an orthodontic uprighting of M II using different uprighting techniques depending on the patients periodontal status and biotype, namely: 50% by uprighting spring, 30% by orthodontic implant and 20% by the tip back procedure.
Results and conclusions: Further to molar uprighting we noticed the clinical and paraclinical improvement of the gingival and periodontal tissue status, a 2 mm decrease of the periodontal bags and bone level remodeling. We therefore think that this type of orthodontic treatment applied to II year molars with periodontal conditions results into local status improvement and also into stopping the evolution of the pathological phenomenon affecting the tooth support tissues
