Immediate implant prostheses – a guided surgery approach in anterior maxilla
The speaker began by presenting relevant scientific background for four topics related to his clinical case:
- immediate implant placement: a 2mm gap and the use of DBBM-C bone substitutes can reduce buccal plate resorption (Vignoletti & Sanz. 2014; Sanz et al. 2017)
- digital planning and guided placement: this can result in more accurate treatment than 2D planning and/or freehand placement (Schnutenhaus et al. 2018; Vercruyssen et al. 2014)
- immediate loading: although this approach shows high survival rates, it is also associated with a higher risk of failure than conventional delayed loading (Sanz-Sánchez et al. 2015). Temporary crowns can improve soft tissue maturation and are strongly recommended (Martin et al. 2014)
- digital impressions: these are already considered a valid option in single and partial implant-supported restorations (Rutkūnas et al. 2017)
The speaker then presented his case: teeth 12 to 23 were replaced with three implants at 11, 21 and 23. Both the provisional PMMA restoration and the final zirconia restorations were screw-retained.
“The digital workflow allowed a precise comparison to be made between the ‘before and after’”
The digital workflow allowed a precise comparison to be made between the ‘before and after’. The accuracy of implant placement and the volumetric changes of the soft tissue were compared by superimposing the images, giving satisfactory results.
