Monophasic and conometric implants in comparision to other implant connections: Which one is better?

The volume of the maxillary sinus tends to increase in size with advancing age and with the loss of dental elements. For this reason, in some clinical situations, it is not possible to place dental implants of adequate length, mainly due to the lack of bone. The aim of this work is the evaluation of the clinical and radiographic results of the large maxillary sinus lift using the lateral window technique with Piezo Surgery and contextual GBR (Guided Bone Regeneration). Piezoelectric surgery has demonstrated the benefit of dramatically reducing the perforation rate, thus increasing the overall success rate of the sinus lift technique. Aim: The study aims to compare conometric and monophasic implant connections with other types of connections, focusing on minimizing the "pumping effect" and understanding their clinical implications. Material and methods: The study involved replacing 20 teeth in the upper and lower frontal areas with IML implants, with a 3-year follow-up period. The results showed effective osseointegration and minimal bone resorption, particularly in the interincisive papilla region. Results and conclusion: The findings emphasized the positive influence of conical connection dimensions on the marginal crest. Clinically, innovations such as tapered connections and platform switching offer strategies to reduce crestal bone resorption and improve osseointegration. These technologies eliminate the need for fixation screws, reducing micromovements and bacterial colonization. Platform switching helps preserve crestal bone and soft tissue, leading to improved aesthetic outcomes. However, successful implementation requires surgical precision and understanding of biomechanical principles. Further research is essential to optimize these technologies and assess their long-term effectiveness through controlled studies.
