<abstract>
<p>Tooth structure loss remains a central concern in conventional crown preparation, where significant enamel and dentin reduction is required to accommodate restorative materials. Although full-coverage crowns provide functional and esthetic rehabilitation, the process of preparing a tooth for such restorations can compromise its long-term integrity. The extent of structural loss depends on multiple variables including the type of crown, margin design, occlusal clearance, and the technique employed by the clinician. Over-preparation increases the risk of pulpal injury, dentinal hypersensitivity, and fracture, especially in posterior teeth subjected to high occlusal loads. The removal of peri-cervical dentin and the reduction of enamel undermine the biomechanical stability of the tooth, reducing its resistance to functional stresses. Conventional techniques often rely on subjective visual assessment, which can lead to unnecessary removal of sound tissue. Operator variability further compounds this issue, with studies showing frequent deviations from recommended guidelines. Modern approaches focus on limiting these effects through the use of depth-limiting burs, magnification tools, and digital planning systems. Partial coverage restorations, when appropriately bonded, offer a more conservative alternative while maintaining comparable clinical performance. Reduction guides and intraoral scanners also assist in maintaining precision and reducing the biological cost of treatment. Preserving tooth structure during preparation is closely linked to long-term prognosis and overall restorative success. Careful technique selection, attention to anatomic preservation, and the integration of available technology can reduce structural loss without compromising the durability or function of the final restoration. As clinical practices continue to evolve, the emphasis is gradually shifting from purely mechanical preparation strategies toward biologically respectful and minimally invasive solutions.
