In a severely resorbed maxilla, JDNasal® Implants can be used to make 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.
Site Preparation Sequence
- Initiate the site preparation with the Ø2mm 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 drill to drill through the alveolar, into and across the sinus, engaging the lateral nasal wall
- The 26mm depth gauge can be used to palpate the hole depth for implant selection
- Drill to final depth with the Ø2.4mm drill
- Place the implant till to reach the final position
- NB: If the alveolar bone is less than 3mm thick or of poor quality then bone grafting must be applied. Open a window in the lateral sinus wall. Gently reflect the Schneiderian membrane and insert bone graft into the sinus
