Male patient, 51 years old.

Chief complaint: Dental fracture.

Initial evaluation: Patient fractured element 26 where there was an amalgam restoration that involved a large part of the mesiopalatine cusp. The fracture extended far beyond the cement-enamel junction, close to the marginal bone crest and compromised the biological space.

Treatment performed

As it was not possible to perform surgery to recover the biological distance and promote periodontal health, and in order to preserve the interradicular septum so that the installation of an implant was possible in the same surgery, a minimally traumatic extraction was performed with dental sectioning. After extraction and bone preservation, a 4.3x5mm Arcsys® implant (FGM) was installed at the site with a torque of 10N. The root alveoli were filled with Nanosynt® sticky bone (FGM). To close the socket of the alveolus, 4 autologous leukoplate fibrin or LPRF membranes and the open wound technique were used, aiming to form a greater amount of keratinized soft tissue on the site. The patient was evaluated after 7 and 30 days.

After 4 months of healing, reopening surgery was performed. Excellent local bone formation was observed, which covered the silicone cap. The cap was delicately exposed, the Arcsys system reamer was used, and a 4.2x4x2.5mm abutment was installed. A roll flap technique was performed to increase the tissue volume in the vestibular area, and a temporary crown was made over the multifunctional transfer. 60 days will be necessary for the peri-implant tissue to heal and for the final crown to be made.
