Preparing the temporary prosthesis1. Transferring the planned implant position to a master modelIn order for your dental laboratory to be able to prepare the temporary bridge beforehand,they should be able to produce a model in which the implant positions are known and implantanalogues can be positioned.There are several options to create a so-called ‘virtual osteotomy model’ or ‘digital cast’ of theimplant setup.A. Order a stereolithographic digital cast.The first option is to order a virtual osteotomy model along with your SurgiGuide. Materialisecan provide you with an exact copy of the patient’s anatomy, and virtually perform the surgeryby already preparing the osteotomy holes in the model. Simply provide Materialise with theexact dimensions of the implant analogues to be used.Your dental laboratory can position the implant specific analogues in this model and start thepreparation of the temporary bridge based on this model.B. Use the SurgiGuide to simulate the surgery by drilling into a model of the patientanatomy.For Mucosa Supported SurgiGuide or Tooth Supported SurgiGuide, you could choose to usethe SurgiGuide of your patient to simulate the surgery on a plaster model of the patient’s jawbefore the actual surgery. You can simulate the surgery, providing your dental laboratory witha model in which they can position the implant specific analogues. It is advisable to use oldsurgical drills or drills dedicated for drilling in plaster.For Bone Supported SurgiGuide you can use the delivered stereolithographic model toprefabricate the osteotomies. This will provide your dental laboratory with a model in whichthey can position the implant specific analogues. To prefabricate a temporary prosthesisbased on a bone model, an extra step will be needed in the dental laboratory to simulate themucosa level of the patient. This might introduce a slight deviation that can be overcome atthe moment of adapting/relining the temporary prosthesis.Be careful to take the same depth measures into account as you will during surgery. SimPlantmeasurements and specific measures received with your SurgiGuide can help you with this.SURGICAL PROCEDURESFigure 2 :Order a stereolithographic model with osteotomy-sites prefabricatedor simulate the drilling on a jaw model (1)84www.SimPlant.comSurgiGuide Cookbook
2. Creating the temporary prosthesis based on the created master modelBased on the master model with simulated osteotomy sites prepared in the previousparagraph, the dental laboratory will be able to create a temporary bridge for your patient.The first step will be to articulate the master model referenced to the antagonistic jaw. For thetransmucosal approach, the articulation can be done based on the patient occlusion. Also forpartial edentulous bone supported case, the teeth can be used for articulation of the model.For completely edentulous bone supported cases, a simulation of the mucosa level will haveto be done, based on measurements of the mucosa thickness at certain positions, measuredin SimPlant or using needle punction measurements. Simulation of the mucosa level mayintroduce an additive error to the procedure. This can be overcome by providing biggertolerances to achieve a good adaptation/relining of the temporary bridge to the final implantpositions.Once the model is articulated, the dental laboratory can create an acrylic temporaryprosthesis in the conventional way, as if they would have received a model after post-surgicalimpression taking. Both situations start from a model with analogues. The only difference isstarting the fabrication from a simulated position, not from the final, post-surgical position ofthe implants. At this step, aesthetics, phonetics, occlusion, bite function, … should be takenin to account.Of course, the surgical situation may differ from the simulated situation, and for that reason, itis important to make an adaptable prosthesis. The dental laboratory can provide holes in thetemporary bridge which are slightly bigger in dimension than the abutments that will be usedon the implants after surgery. As such, the bridge can be fitted on the patient, and the holescan be filled with auto-polymerising resin. The size of the provided holes should be based onthe direction and parallelism of the planned implants. This system with a ‘relined temporarybridge’ is very easy to do and can eliminate costly adjustments.Another option is to use adaptable abutments. Special abutments are available on the marketthat allow for limited surgical deviations. Using these special abutments, it may be possible touse screw fixation. If surgical deviations exceed the limits of the adaptable abutment,adjustments may be necessary in the surgical theatre to adapt the prosthesis, comparable tothe auto-polymerising procedure.SURGICAL PROCEDURESFigure 3:The dental laboratory creates a temporary bridge basedon the model simulating the surgery (1)85www.SimPlant.comSurgiGuide Cookbook
