This retrospective study aims to value the bone loss and the success and survival of the dental implants produced by additive manufacturing installed in an area grafted with Plenum® Osshp (synthetic bone graft). In addition, the biological and biomechanical performance of implant restorations supported through an observational retrospective solution will be observed. From 50 to 100 survey participants will be selected, who will be invited to attend the clinic for clinical, radiographic, and prosthetic evaluation and successful parameters between baseline, 3, 6, and 12 months. The data obtained regarding bone loss (primary outcome) of the analyzed regions and implant success and survival in area grafted with Plenum® Osshp (secondary outcome) will be evaluated by the paired t-test for the evaluation of the times (3, 6, and 12 months) and survival curves of the installed dental implants.

The survival rate of dental implants produced by additive manufacturing installed in pristine bone and grafted areas with synthetic bone graft (Plenum® Osshp).
The main outcome is the survival rate (%) of successful implant-supported restoration after at least 1-year of occlusal loading (less than 0.5mm of bone loss)
Time frame: 12 months
The survival rate of dental implants produced by additive manufacturing installed in different areas grafted with synthetic bone grafts (Plenum® Osshp)
Survival rate (%) of successful implant-supported restorations (less than 0.5mm of bone loss) placed in different bone areas (pristine bone, grafted areas with Plenum Oss including maxillary sinus augmentation, guided bone regeneration for both vertical and horizontal augmentation, and extraction sockets).
Time frame: 12 months
Rate of bone loss
A periapical x-ray will be performed at the implant placement region to check the bone level concerning the implant platform. Then, a vertical line will be drawn from the initial line to the bone level for measurement (mm). Standardized intraoral periapical radiographs will be obtained using a dental X-ray machine with a 35 cm long cone. The exposure parameter was 70 kV (Peak), 15mA, and 1/4s at a focus-sensor distance of 30cm. The X-rays will be captured with a digital camera and transferred to a personal computer. Image processing software will be used to store the scanned images. Subsequently, the images will be made available on a monitor and a linear measurement will be performed with software.
Time frame: 12 months
