             STEP 4: SURGICAL PHASE
             The surgical guide was seated in position using anchor pins. The guide was
             tooth- and tissue-supported (Figures 13a,13b and 13c). This ensured that
             the surgical guide obtained stability both from the mucosa and teeth. The
             implants were placed first and then the extractions of the remaining teeth
             were carried out. Multi-units (implants) were placed in position according to
             the gingival height thickness, which was already determined in the planning
             software (Figures 14 and 15).

             STEP 5: TEMPORIZATION STAGE
             A postoperative CBCT was taken to confirm the planned and executed
             implant positions. Pickup of the temporary prosthesis was done intraorally.
             The intaglio surface of the prosthesis was finished and the PMMA was
             screwed over the multi-units. Shim stock drag, protrusive and laterotrusive
             movements were checked for. Occlusal prematurities were corrected to
             achieve simultaneous bilateral contacts, or the so-called implant-protected   Fig 4: Full mouth x-ray of the patient

                                                                                          AND FOLLOW-UP
                                                                                          This is a very important step in immediate loading for
                                                                                          full-mouth rehabilitation. The patient was instructed
                                                                                          to have a semi-solid diet for a period of 4 weeks until
                                                                                          secondary stability was completely established. He was

                                                                                          temporization and osseointegration, the PMMA required
                                                                                          timely corrections, and the implants required regular
                                                                                          radiographs to check for any signs of bone loss, mucositis,
                                                                                          loosening, or breakage of the temporary prosthesis.
