Periodontal plastic surgery associated with orthodontic movement for root coverage in a case of gingival recession of a buccally positioned tooth

In case of stabilized recessions orthodontic treatment, it is possible to at least partly repair periodontal damage and to create the anatomical conditions for spontaneous coronal migration of the attachment and the periodontal tissue or to improve the outcome of surgical therapy.

Effective movements to achieve this result includes bodily movement and lingual root torque.

A 27 years old female patient, non-diabetic and non-smoker, presented with severe gingival recession of a lower incisor, complaining about esthetics e sensitivity.

She was also very concerned about losing her tooth.

Conclusions

The combined ortho-periodontal therapeutical approach may give optimal esthetics and functional results eliminating the risk of losing malpositioned and periodontally involved teeth.
