This report presents a case in which autogenous bone grafts were harvested from the maxillary tuberosity for guided bone regeneration and dental implant placement, with long-term follow-ups and assessment at the clinical, tomographic, and histologic levels. Particulate and block autogenous bone grafts were covered with a resorbable collagen membrane. Advanced bone remodeling and good bone quality, enabling dental implant placement, were observed after a short healing time (3 months). The differences in buccal bone plate thickness in the grafted area between the period immediately after implant placement and 4 years thereafter ranged from +0.879 mm to -0.001 mm. The implants osseointegrated uneventfully, and alveolar bone regeneration remained stable with a satisfactory result after 4 years.

This article describes the combined use of the immediate dentoalveolar restoration (IDR) technique and the osseodensification implant site preparation method to improve immediate implant primary stability in periodontally compromised extraction sites. Positioning of soft and hard tissues was evaluated in two clinical cases in which the IDR technique and the osseodensification implant site preparation method were used to replace teeth at sites with severe alveolar bone loss. The results were analyzed by clinical assessment, photography, radiography, and computed tomography scans. Based on this preliminary study, the use of osseodensification can enhance the results achieved using the IDR technique due to improved primary implant stability, as measured by higher insertion torque.

The aim of this prospective case series was to evaluate the stability of esthetic treatment after single tooth replacement in compromised sockets using the immediate dentoalveolar restoration (IDR) concept. Eighteen patients underwent immediate implant placement and IDR of bone defects. Clinical photographs were used to evaluate the gingival contour and papillae. The mean soft tissue dimensions at baseline and final follow-up were 12.85 ± 2.33 mm and 12.79 ± 2.48 mm, respectively, revealing no recession. The mean mesial and distal papillary heights increased slightly over time. Stable periimplant soft tissues and satisfactory esthetic outcomes were achieved.

Purpose: The aim of this paper is to describe a protocol for a one-stage technique called Immediate Dentoalveolar Restoration (IDR), which uses autogenous bone grafts to restore peri-implant bone defects, presenting the results of mid-term follow-up. Summary: The patient presented a left central incisor that was compromised and with a total loss of buccal bone wall. The proposed treatment followed a protocol of immediate implantation, with a flapless surgery, using corticocancellous bone graft harvested from the maxillary tuberosity to restore the bone defect in question. The graft was shaped to the defect size and inserted between the implant and the remaining buccal soft tissue. The provisional restoration was made at the same time. The patient was followed for 36 months. The results were analyzed by means of clinical assessment, photography, periapical radiography and cone beam computed tomography. Conclusion: The treatment described appears to afford satisfactory esthetic results, with lower overall costs and treatment time.
