Temporary crown

[2] The functions of temporary crowns are: Problems A tooth-coloured shell that is slightly larger than the tooth preparation is selected and is reduced to the correct dimensions using a bur until it seats fully on the tooth preparation without bedding into the gingiva.

Petroleum jelly is smeared over the tooth and acrylic resin is spread over the fitting surface of the crown.

Small holes can be made on the canine tips, incisal angles and cusps with a probe before filling crowns with acrylic resin to reduce risk of bubbles formation.

Final check for occlusion, fit and margins can be carried out prior to cementing provisional restoration.

[5] Custom-formed provisional crowns allow for shaping of the gingival tissues in order to achieve a satisfactory emergence profile of the definitive restoration.

[6] However, eugenol has an inhibitory effect on the polymerisation of methacrylate-based resins,[7] and may potentially lead to a lower resin-dentine bond strength.

[9] Oral hygiene tooth brushing and flossing is crucial to prevent gingival inflammation and bleeding.
