Depending on the clinical findings, six treatment scenarios may be considered. Most of these may be deferred to later treatment.
6. Extraction may be performed with immediate or delayed implant-retained crown restoration or the use of a conventional bridge. Extraction is inevitable in deep crown-root fractures, the extreme being a vertical fracture going towards the apex.
Crown-root fractures with a course as illustrated will inevitably lead to periodontal break down along the entire length of the fracture. For this reason, early diagnosis is essential for the prognosis of later implant restoration.
All of the treatment modalities (except extraction) are technique sensitive and do not need to be performed in the acute phase. Instead, the coronal fragment can be temporarily bonded to the cervical portion of the tooth with a composite or resin. This may add to the comfort of the patient until the patient’s final treatment. Prognosis will not be influenced by delay of treatment within a time frame of 1 to 2 weeks.
Ideally, and as a temporary measure, immobilization of the coronal fragments prevents pain during occlusion and chewing,
Digital pressure on the lingual aspect of the crown reduces the fracture and normalizes occlusion.
After etching with phosphoric acid the two fragments are splinted together with composite resin. This treatment gives the patient a waiting period with the tooth still in situ for the planning of the definitive treatment.
Aftercare includes follow-up of pulpal vitality and restoration of the crown in cases not involving the pulp. Most cases will need endodontic treatment (exceptions are cases of immature root formation where partial pulpectomy is an option).
