JDNasal

Nasal Anchorage

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.

site preparation sequence

  1. Initiate the preparation of the implant site with standard twist drill Ø2 mm in order to reach and perforate the floor of the maxillary sinus. It is always advised to open a window in the lateral sinus wall and gently reflect the Schneiderian membrane without perforating it. Keep the drill with a right inclination towards the canine pillar.
  2. Continue with standard twist drill Ø2.4 mm till to reach and perforate the floor of the maxillary sinus.
  3. Continue with standard twist drill Ø2.8 mm till to reach and perforate the floor of the maxillary sinus.
  4. Continue with standard twist drill Ø3.2 mm till to reach and perforate the floor of the maxillary sinus.
  5. Insert the Ø1.5 mm JDNasal® drill into the bone canal created before. Drill through the alveolar process, into and across the sinus, engaging the nasal bone in correspondence with the canine pillar.
  6. The 26mm depth probe can be used to sound and check the depth for implant selection.
  7. Use the Ø2.4 mm JDNasal® drill to drill like the previous one through the alveolar process, into and across the sinus, engaging the nasal bone until the final depth in correspondence with the canine pillar.
  8. Complete the osteotomy with standard twist drill Ø3.6 mm in the alveolar process.
  9. Place the implant and reach the final position.
  10. 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.

Longer twist drills Ø2mm and Ø2.4 mm for nasal implants are available in order to reach directly the nasal bone reducing the drilling steps. Make sure to be able to maìntain the right inclination towards the canine pillar.

 

Computer Guided Site Preparation Sequence

  1. Start the osteotomy using the first JDGuided Drill JDGD24-060 Ø 2.4 x L 6 mm.
  2. Continue using JDNasal Guided Drill Ø 2.0 at the same implant lenght to be inserted (Choose among JDNasal Guided drills L 20-22-24-26 mm).
  3. Continue using JDNasal Guided Drill Ø 2.4 at the same implant lenght to be inserted (Choose among JDNasal Guided drills L 20-22-24-26 mm).
  4. Continue with JDGuided Drill Ø2.8 mm for L 6 mm.
  5. Continue the osteotomy with JDGuided Drill Ø3.2 mm x L 6 mm.
  6. Complete the osteotomy with JDGuided Drill Ø3.6 mm x L 6 mm.
