Treatment of dental subtotal coronal lesion through atraumatic surgical extrusion

Abstract

Background: Clinical short crowns or teeth with insufficient height of the supragingival part are a provocation for restorative dentistry. Restoring severely damaged teeth requires a comprehensive approach, a well-planned pretreatment. These teeth with subtotal coronary dental lesions can be treated conventionally by surgical resection of the gum and support bone or by the atraumatic surgical extrusion of the tooth as an alternative to avoid complications that may occur following removal of tissues. Now, the world’s population lives longer. The hope of life according to WHO in 2016 was 72.0 years old. Respectively, the requirements of the people are higher in order to maintain oral health and effective treatment for the preservation of their own tissues. The atraumatic surgical extrusion of the tooth is a biological solution for the preservation of the tissues, but due to the recent implementation is not fully evaluated its effectiveness. Conclusions: The Benex system can offer certain advantages to both the patient and the clinician, including the predictability of maintaining the stability and integrity of the dental alveole after the extrusion, due to the applied vertical force. Furthermore, the axial force for several minutes minimizes the oblique and lateral force that decreases compressive manipulations in the periodontal ligament and risk of resorption defects. However, the given technique can be resulted in unpredictable results, because it is an innovative technique and there is a small number of scientific studies on the subject.
