Of the following, what is the BEST treatment for a Class IV fracture of a lateral incisor with no pulp exposure and otherwise healthy teeth?

  1. Bonding: this is the most conservative treatment for a Class IV fracture of this tooth
  2. Provisional: this will allow you to assess the tooth's long-term nerve health
  3. Porcelain Jacket Crown: this will allow you to most closely match the adjacent teeth

Answer(s): C



Regarding the occlusion on an implant restoration, which statement is correct?

  1. There is much more tensile and compressive stress with vertical loading compared to an angled load on an implant
  2. Compressive loads on an implant crown make the crown height act as a lever and force magnifier
  3. Lateral forces represent a significant increase in stress compression compared with vertical loading
  4. The direction of the occlusal load results in minimal differences in the amount of force exerted on an implant system

Answer(s): C
