New Stereophotogrammetry System to Capture Complete-arch Impression

The Use of a New Stereophotogrammetry System to Capture Intra-operative Complete-arch Impression

Patients in need of complete arch restorations will be treated with dynamic navigation system. Once the implants are positioned, a new system of stereophotogrammetry will record the implant positions to capture a precise impression to deliver a fixed screw retained interim prosthesis

4. Bone width of at least 5 mm and 6 mm for narrow (NP 3.75/3.5 mm) and regular (RP 4.3 mm) implants, respectively
5. Fresh extraction sockets with an intact buccal wall
6. At least 4 and 5 mm of bone beyond the root apex in the mandible and maxilla
7. Minimal insertion torque of 45 Ncm

Exclusion Criteria:

1. General medical (American Society of Anesthesiologists, ASA, class III or IV) and/or psychiatric contraindications
2. Pregnancy and/or breastfeeding
3. Any interfering medication such as steroid therapy or bisphosphonate therapy
