Filter by:The One tooth - One time (1T1T) innovative approach is a straightforward and cost-effective protocol to replace a missing tooth in the posterior region (Lambert and Mainjot 2017) (see Appendix). The digital impression of single unit implants right after the implant placement and the direct manufacturing of a Polymer-Infiltrated Ceramic Network (PICN) screw-retained crown allows the delivery of a final tooth in occlusion within the same day. The absence of lab procedures reduces the number of appointments, providing immediate results and high patient satisfaction. The prosthesis material choice is crucial in this procedure. Indeed, PICN high resilience, i.e. damping effect, could reduce peri-implant strain compared to ceramic materials (Magne, Silva et al. 2013) (Maminskas, Puisys et al. 2016), moreover its elastic modulus is close to tooth tissues, while other CAD-CAM composites value is too low and ceramic materials are too high. The rapid milling and manufacturing process, without any firing procedure, and the ease of adjustments (particularly to adjust proximal and occlusal contact points), make also PICNs well-adapted to chair-side systems. The material low stiffness and hardness can improve patient comfort and promote adaptation of the restorations to occlusal relationships with time. The 1T1T approach was presented as a proof of concept in a first international publication using tissue level implants from Straumann, which describes the whole protocol (Lambert and Mainjot 2017). Currently, a case series including 10 teeth is on-course, showing a 100% survival rate of implants and restorations after a 2-yr follow-up. These results are very promising but further clinical research is needed to validate such a protocol on a larger number of patients, on other implant systems as well as to compare this approach to conventional protocols.
Proper implant position has a significant impact in esthetic and functional outcomes of implant-supported restorations. Computer-assisted template-based implant placement (guided surgery) have become increasingly popular due to improved planning and the higher transfer accuracy of the virtual plan to the surgical site compared with freehand insertion or freehand final drilling. Digital impressions replace the need for traditional materials that can be inconvenient and messy for patients. To the best of our knowledge, at the time of planning this study, there were no published RCTs evaluating a fully digital approach for computer-assisted template-based implant placement. The aim of the present study is to compare early implant failure, template-related complications, and virtual planning accuracy of computer-assisted template-based implant placement using conventional impression and scan model or digital impression. The null hypothesis is that there will be no difference between these interventions.
The purpose of this prospective clinical trial is to investigate and identify factors associated with the failure of dental implants within the population rehabilitated with dental implants at the Folktandvården Specialistklinik in Malmö (Spårvägsgatan 12, 214 27, Malmö).
