  • Title: Trans-surgical restoration of extensive Class IV defects in the anterior dentition.
    Author: Fahl N.
    Journal: Pract Periodontics Aesthet Dent; 1997 Sep; 9(7):709-20; quiz 722. PubMed ID: 9743678.
    Abstract:
    Direct bonding is the most commonly utilized treatment for conservative aesthetic restoration of the anterior dentition. Class IV defects require special attention due to their high incidence, particularly in young patients. One of the major challenges for the clinician in treating defects in this category is selecting the appropriate restorative composite resin material that emulates the physical and optical characteristics of dentin and enamel and conceal the fracture line at the tooth/composite interface. Class IV defects with margins violating the biologic width present another concern, since this violation often impedes the attainment of the correct anatomic contours. The learning objective of this article is to describe a technique for achieving a correct integration of the periodontium, the tooth structure, and the restorative composite resin material to achieve a high level of aesthetic excellence.
