This implant is available in cylindrical and conical versions, and both can be used in most surgical situations., including the GBR (Guided Bone Regeneration) operations with simultaneous insertion of the implant, where the macromorphology of both lines produces high primary stability. The particularly aggressive threading and the perfect fit to the implant alveolus result in a stable fixation without difficulties. The conical shape is particularly suitable in situations with reduced apical space (e.g. apex of converging teeth towards the implant site, oblique oral wall of the mandibulary body ), in operations of split crest and in maxillary sinus lift, where the conical shape reduces the risks of accidental perforation of the sinus membrane . This kind of system, conceived as a trans-mucotic method, can be also used with submerged techniques . The internal polygonal implant-abutment connection has a geometry that uses a cone inside which there is an octagone. The system is extremely stable due to the mechanical principle of the a double cone and at the same time it is possible to transfer precisely the information to the laboratory not only with pick-up or transfers with passing screws, but also with snap-on caps. The greater use of Shiner implants is in the sectors: molar, premolar and upper central incisors , although they can also be used in different areas.
