The atraumatic technique of restoration/reconstruction of incisal edge of the defective tooth depth 2 mm using composite materials

The atraumatic technique of restoration/reconstruction of incisal edge of the defective tooth depth 2 mm using composite materials. This article is describe the atraurnatic pateпted technique of restoration of incisal edge with 2 mm defect using а composite which allows to restore integrity of incisal edge in the direct way. The incisal edge is restore with the account of aпatomico-topographic апd biomechanical features of tooth crown. The roughness formation, retentional points апd reteпtioпal cavities with а diflicult geometrical configuration provide retention of composite material with hard tooth tissues and increase the duraЬility of restoration. 

The generally accepted causes of damage to the incisal edge of the teeth are currently considered carious and non-carious lesions (abnormal abrasion), traumatic fracture. For the restoration of the incisal edge of teeth in clinical practice, artificial crowns, veneers, and composite materials are used. However, the use of composite dental materials to eliminate incisal defects up to 2 mm deep is ineffective and rarely used. This is due to their physico-mechanical and chemical properties, which are the root causes of complications such as chipping and spalling of the restoration.There are currently no effective methods for eliminating the defect cutting edge of teeth up to 2 mm deep, and therefore restoration of the integrity of the incisal edge of a damaged tooth remains one of the urgent problems in dentistry.

The purpose of this work is to develop a method for restoring the incisal edge of a damaged tooth with a depth of up to 2 mm, which ensures the durability of functioning. In order to eliminate the shortcomings of the composite dental materials, various reinforcing elements are introduced into composite materials, that is, reinforcement (strengthening) of the composite restoration is carried out.  To achieve this goal, we have developed and patented a method for eliminating an incisal defect up to 2 mm deep using composite materials.

To restore the integrity of the incisal edge, macrophilic and microfiltered composite materials are used. A unique complex geometric configuration of the retention cavity of the restored tooth, provides reliable retention of the composite material with the hard tissues of the tooth, while preserving as much as possible the healthy intact tissues of the tooth (Minimal Invasion Dentistry - MID), taking into account the anatomical, topographic and biomechanical features of the incisors.
