Dental balance in the arcs for the implants: a concise systematic review

Abstract

The teeth together perform the functions of mastication, protection, and support of related soft tissues, help in the articulation of words, and are an important factor in the aesthetics of the face. The macro geometry of the implant provides influences on osseointegration. In this sense, the various isolated characteristics (thread type, thread pitch, thread depth, face angle) must be studied so that the implant geometry can balance the compressive stress and tensile stress and produce a minimum shear force. The present study aimed to carry out a concise systematic review of the main considerations of dental balance in the arches in implant dentistry. Thus, knowledge of the direction of the teeth is of great importance in clinical implant dentistry for the correct installation of implants, which are very important for maintaining the balance of forces exerted by masticatory muscles (masseter muscle, temporal muscle, medial pterygoid muscle). In addition to this, the evaluation of the amount and density of bone available in the patient's edentulous site. It was concluded that the optimized aesthetic positioning of the implant presents numerous factors for the good aesthetic performance of an implant-supported prosthesis. The main conditions of the soft tissues, the amount of bone, and the location and inclination of the placed implant can be cited as the main ones. The correct positioning of the implant is linked to the location and axial inclination of the implant, aiming to favor the emergence profile and aesthetic contours of the prosthesis. The ideal location for the implant would be the one assumed by the lost tooth root. Also, the location of the height of the cervical portion of this implant concerning the adjacent teeth is important for determining the prosthetic space available for making the restoration, as well as its emergence profile and the biological space of the surrounding soft tissues.
