Brief summary
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.
Interventions
PROCEDUREDental Implants installed in an grafted area (sinus lifting)
The patient will be invited to participate in the clinic to assess radiographic bone loss and clinical follow-up for 12 months.
PROCEDUREDental Implants installed in an grafted area (ridge augmentation)
The patient will be invited to participate in the clinic to assess radiographic bone loss and clinical follow-up for 12 months.
PROCEDUREDental Implants installed in an grafted area (extraction sites)
The patient will be invited to participate in the clinic to assess radiographic bone loss and clinical follow-up for 12 months.

Inclusion criteria
Clinical parameters: * Presence or absence of pain or tenderness * Presence or absence of suppuration or exudation * Presence or absence of mobility Prosthetic parameters \- Presence or absence of mechanical complications (problems in prefabricated components such as screws and abutments). Radiographic Parameters * Presence or absence of peri-implant radiolucidity. * maintenance and quality of the bone graft volume in the grafted area to each clinical indication: ridge augmentation, extraction sites (socket preservation or dental implant preparation/placement) and sinus lifting. * Distance between the shoulder of the implant and the first visible bone contact (in mm). * Presence or absence of technical complications such as fracture or loss of porcelain structures. Success Parameters * Absence of pain or tenderness. * Absence of suppuration or exudation. * Clinical absence of implant mobility. * Absence of peri-implant radiolucency. * Minor loss of up to 1.5mm in the first year of function. * Absence of mechanical or technical complications in the dental implant and in the prosthesis to the dental implants installed in an area grafted.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The survival rate of dental implants produced by additive manufacturing installed in pristine bone and grafted areas with synthetic bone graft (Plenum® Osshp). | 12 months | 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) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The survival rate of dental implants produced by additive manufacturing installed in different areas grafted with synthetic bone grafts (Plenum® Osshp) | 12 months | 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). |
| Rate of bone loss | 12 months | 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. |
