ABSTRACT

When a tooth has suffered serious destruction, the dentist needs to carefully evaluate the condition of the remaining dental tissue, as well as the configuration of the cavity after its final preparation, in order to determine whether any additional means of retention or anchorage is needed for the final restoration (e.g., amalgam, composite resins or glass ionomer cements) when the bonding proves insufficient. Following the introduction in today’s dentistry of dental materials with excellent bonding ability to both enamel and dentin, the belief among clinicians has come to be that retention pins are now obsolete, an opinion backed by various authors. However, today’s clinical practice and day-to-day work with patients would tend to indicate quite the contrary, as it is clear that despite the bonding strength of dentin adhesives and glass ionomers, in certain special cases retention pins are a necessary resource that provide extra bonding, even after using these materials. The addition of these retention pins is called for in special cases, particularly when there are missing cusps (stamp cusps in particular), when core reconstruction of seriously damaged vital teeth is carried out to prepare crowns, when the anterior teeth have extensive fractures, and also when teeth are seriously occlusally compromised. This paper will describe a technique for placing retention pins, along with a number of clinical cases in which this procedure is required.
