Introduction: Traditionally Prosthodontists have been designing full coverage restorations for badly mutilated and endodontically treated teeth. This procedure involved removal of enamel and exposure of underlying dentin to bear the disruptive tensile forces ,which structurally it is not designed to bear. The exposure of dentin may lead to flexural pain, crack propagation and ultimately fracture in future. Evidence now supports that tooth is shaped like compression dome,similar to that of a cathedral. New nomenclature describes the functional zones on a tooth as “Bio Dome” and “Bio Rim”. The coronal half of the compression dome is being described as the Biodome, and the cervical half of the tooth(below the contact area) that essentially supports the coronal compression dome is being called the Bio-Rim.
Summary: Prosthodontists should focus on preserving the Bio-Rim as much as possible, within the parameters dictated by existing damage from previous restorative efforts, trauma or decay. The ultimate aim of the restorative dentist should be preservation of Bio-Rim, which is otherwise disrupted while placing a crown. Retaining the Bio-Rim by placing adhesive onlay restorations helps to recreate the Bio-dome and restore biomechanical function.
Conclusion: This paper aims at explaining the importance of preserving the Bio-Rim and its implications in restorative dentistry, while it unveils the Compression Dome Concept.
