D A Fig. 19 Fig. 19: Final result. The Double FiRe Bridge protocol The Double FiRe Bridge protocol imple- mented has several advantages: – an aesthetic advantage, because there are no holes in the occlusal surface for screws; – a functional advantage, because the clini- cian can decide at any time to switch from a fixed prosthesis to a removable one (or vice versa); – a hygiene advantage, because the struc- ture offers good maintenance and can be checked with greater simplicity. By using the Double FiRe Bridge protocol, it was possible to combine aesthetics, struc- tural passivity, hygiene and functionality in one prosthetic rehabilitation by solving some problems that may be encountered with conventional full-arch fixed resto- ration. Furthermore, the use of tilted im- plants allowed the reduction of the cantile- ver of the structure, despite the greatly pneumatised maxillary sinuses, and allowed improved transmission of the masticatory load. The characteristic of having an angled connection from the implant’s main axis enabled the divergence to be solved immedi- ately, giving the freedom to tilt the implants even more. In this way, it is possible to apply the cantilever protocol in a simpler and faster way without the interposition of additional prosthetic components. In the Double FiRe Bridge protocol, the prosthesis consists of two structures (a pri- mary structure and a secondary superstruc- ture), solidly joined together owing to the insertion of two palatine locking screws. Fol- lowing this workflow, it is possible to provide the patient with a fixed solution that can be converted into a removable device if neces- sary by simply removing the palatine/lingual fixing screws, if the patient’s hygiene main- tenance is poor or if better support of the soft perioral tissue is necessary. This proto- col is also helpful for the case in which the patient asks to first try a fixed prosthesis and then to eventually switch to a removable one (or vice versa). Having two structures locked together by lingual fixing screws also elimi- nates occlusal access holes, providing obvi- ous aesthetic and structural advantages. In addition, the ability to quickly and easily re- move the prosthesis during check-ups al- lows for more careful and accurate fol- low-up of the patient and therefore provides a longer-lasting rehabilitation through it being more easily inspected. The protocol implemented in the present study proved to be a successful therapy and its association with the use of OT Equator and Elastic Seeger technology simplified the clinical and dental engineering procedures by reducing the treatment time and combin- ing the benefits of a fixed prosthesis and a removable prosthesis within the same reha- bilitation._ contact Dr Marco Montanari Viale Risorgimento, 244/A 47121 Forlì, Italy Tel.: +39 0543 68910 Author details Literature CERASORB® M big and microporeous surface increases osteoconductivity shortened duration of resorption by fast penetration with body own bone supporting structure CERASORB® Foam easy handling thanks to defect-adapted modelling and comfortable positioning CERASORB® – – Always First Choice.
