Deep overbite problem leads to gummy smile in orthodontic patients. The simultaneous intrusion of maxillary (upper) six anterior teeth with mini-implants is a common treatment method for this purpose. Till date, no study has stated desired position of attachment of mini-implant. This is an important parameter as intrusive force vector must pass through centre of resistance (Cres) of maxillary six anterior teeth. Thus, the aim of this study is to obtain the co-ordinates of desired positions of mini-implant with reference to incisal edge of first anterior tooth (maxillary central incisor) from the side view of maxillary six anterior teeth. The purpose is to achieve the effective simultaneous intrusion of maxillary (upper) six anterior teeth. For this purpose, co-ordinates of incisal edge of first anterior tooth (maxillary central incisor), point of attachment of elastomeric chain on the archwire and Cres of maxillary anterior teeth were considered. From these points, the equation to compute co-ordinates of attachment of mini-implants was formulated. Additionally, the required angle of intrusive force was estimated to be 45°. To verify this computation, finite element analysis was performed on the computer aided design (CAD) structures of maxillary six anterior teeth, surrounding tissues and appliance structures. From the formulated equation, four possible positions of mini-implant placements were considered with reference to incisal edge of first anterior tooth (maxillary central incisor). The co-ordinates of these positions were (11, 10.5) - Position {1}, (12, 11.5) - Position {2}, (13, 12.5) - Position {3}, (14, 13.5) - Position {4} with units in mm. From the photographic results of these positions, different statements of recommendations were given in this study from feasibility point of view. Positions {2} and {3} were highly recommended. Position {4} was moderately recommended. Position {1} was least recommended. © 2022
