🔰 Dental Extrusion Due to Lack of Antagonist: Impact on the Curve of Spee and Clinical Solutions
Dental extrusion occurs as a compensatory movement when a tooth loses contact with its antagonist, often following the loss or absence of the opposing tooth. This condition disrupts the occlusal harmony and may alter the Curve of Spee, leading to functional interferences, premature contacts, and complications during prosthetic or implant rehabilitation.
☑️ The clinical management depends on the degree of extrusion and the overall restorative plan. Common treatment options include:
◽ Controlled orthodontic intrusion to reposition the extruded tooth back into the occlusal plane.
◽ Selective occlusal adjustment, in mild cases, to reestablish proper alignment and allow for restorative procedures.
◽ Coronal recontouring with indirect restorations, when the occlusal anatomy requires reconstruction.
◽ Extraction and prosthetic or implant replacement, in severe cases where extrusion compromises function, esthetics, or periodontal health.
👉 An interdisciplinary approach involving orthodontics, prosthodontics, and periodontics is crucial to restore masticatory function and maintain occlusal harmony.
