5.5 Implants in Extraction Sockets: Multirooted Teeth

CLINICAL AND RADIOGRAPHIC EXAMINATION

The intraoral examination showed a visible fracture of tooth 16, crossing the entire surface of the tooth from the mesio- buccal to the midpalatal area. The presence of swelling and an increased probing depth was assessed in the palatal area. In the intraoral periapical radiograph, the fracture was partially visible (Figure 1). The negative prognosis of the tooth was confirmed, and a CBCT was immediately executed to obtain complete infor- mation about the anatomy of the roots and the surround- ing bone. The CBCT revealed the presence of divergent roots and an inter-radicular septum with a favorable anat- omy in order to place an immediate implant; absence of significant radiolucency was also confirmed (Figure 2).

5.5.1 Maxillary first molar

P. CASENTINI

A 32-year-oldman was referred by his dentist to our clinic for treatment of a recently fractured maxillary molar. The tooth had received an endodontic treatment in the past and a direct composite resin restoration. The patient reported a mild dis- comfort in the area without acute symptoms, and he was in- terested in replacing the fractured tooth with an implant-­ supported crown. The patient was not taking anymedication, did not smoke, and reported being in good general health.
