Abstract:
In clinical practice, situations where there is tooth fracture and the margin is subgingival are
common, requiring a multidisciplinary approach. This study aimed to report a case where it
was possible to recover the biological width of a fractured tooth, through a periodontal
surgery to favor the subsequent prosthetic rehabilitation using a free metal crown. Patient
MEMR, 18, leucoderma, female and without systemic involvement, looked for the Clinic-
School of Dentistry at the Federal University of Campina Grande / UFCG with complaint in
smile esthetics. During the anamnesis the patient reported having fractured the element 11,
which was submitted to slow orthodontic traction, and presented with a temporary crown with
cervical infiltration and unsatisfactory coloring. At the clinical and radiographic examination
was diagnosed biological space invasion, and after multidisciplinary planning it was
performed biological space recovery surgery by the technique of apical repositioning flap
with osteotomy because the patient had few keratinized mucosa. A new temporary crown,
previously obtained through study model, was cemented during surgery favoring aesthetics.
After periodontal surgery, the correct gingival conditioning and maintenance of biological
width surgically established enabled the rehabilitation with a total metal free crown. At the
completion of the case, it could be seen that there has been success in the treatment proposed
by the multidisciplinary team. In this way, we emphasize the importance of knowing and
respect the biological distances as well as the correct diagnosis and treatment plan when its
violation.
