In a severely resorbed maxilla Nasal Implants can be used to make use of the nasal bone. JDNasal® Implants enable use of the maxillary bone surrounding the nose. The implant site begins in the alveolar bone at the pre-molar and ends in the bone separating the maxillary sinus and nasal cavity. The specialized implants need to be extra-long to span across the sinus and they need to be angulated. JDNasal® Implant is available up to a length of 26mm. The surgeon can choose to add a bone graft or not. It is mandatory to have no signs of sinus infection before deciding to proceed with this procedure.
Secuencia de preparación de la osteotomía
- Initiate the site preparation with the Ø2mm JDNasal® drill through the alveolar bone. It is advised to open a window in the lateral sinus wall and gently reflect the Schneiderian membrane without perforating it.
- If the alveolar has more than 3mm of good bone, use the Ø2mm JDNasal® drill to drill through the alveolar, into and across the sinus, engaging the lateral nasal wall.
- The 26mm depth probe can be used to palpate the hole depth for implant selection.
- Drill to final depth with the Ø2.4mm JDNasal® drill.
- Continue with standard twist drill Ø2.8 mm at the entrance for 6 mm.
- Continue the osteotomy with standard twist drill Ø3.2 mm at the entrance for 6 mm.
- Complete the osteotomy with standard twist drill Ø3.6 mm at the entrance for 6 mm.
- Place the implant till to reach the final position.
- NB: The surgeon can choose to open a window in the lateral sinus wall. Gently reflect the Schneiderian membrane and insert bone graft into the sinus.
