At the time of implants placement, the healing abutments were submerged and combined with guided bone regeneration at the same time. It was hoped that not only reconstruct the width of the alveolar ridge, but also increase the vertical thickness of soft tissues around the implants. It was expected this technique brought long-term and stable function and health for dental implant patients. Materials and Methods: During implants placement, guided bone regeneration procedure technique was simultaneously used for rehabilitating this area. Preventing space collapse, 3 or 4 mm healing abutments were seated on the implants and allograft was filled in the bony deficiencies and up to the top of healing abutments. Subsequently, the healing abutments embedded in grafts were covered with absorbable collagen membrane. The buccal flap was released to cover the implants with the healing abutments and grafting materials. Six months later, the free gingival graft technique was applied to correct the deficiency of keratinized mucosa and reconstruction of vestibular depth. Finally, we proceeded the impression and delivered the implant prostheses. Results: The follow-up time was 12 months. In case 1, the preoperative and postoperative widths of alveolar ridge 46 were 5.7 and 8.4 mm, respectively. In case 2, the preoperative widths of alveolar ridge 36 and 37 were 3.7 and 5.9 mm, respectively; the postoperative widths of alveolar ridge 36 and 37 were 7.3 and 8.5 mm, respectively. We were able to increase vertical soft tissue thickness and keep the marginal bone stable in these two patients. Conclusion: Submerged healing abutments connecting the implants combined guided bone regeneration procedure is a very effective technique for new bone and vertical soft tissue thickness formation. However, long-term follow up and more clinical cases are required to verify the outcome of submerged healing abutments technique.

Objectives: This review aimed at investigating the impact of bioactive agents on alveolar ridge augmentation at peri-implant sites and edentulous ridges. Material and Methods: Electronic and manual literature searches were conducted for articles up to April 2021. Human randomized clinical trials, clinical trials, or retrospective studies reporting outcomes of alveolar ridge augmentation procedures with or without bioactive agents were included. Sinus lifting or extraction socket preservation articles were excluded in this study. A random-effect meta-analysis was conducted to investigate ridge dimensional changes and complication rate. Results: Overall, ten articles were included in the quantitative analysis. In bone width and height augmentation, the weighted mean difference (WMD) of the horizontal bone gain at edentulous ridges was 0.38 mm (95% CI = 0.07 to 0.69 mm, p = 0.02) when comparing sites with and without PRP/PRF. The WMD of the vertical bone gain at edentulous ridges was 0.46 mm (95% CI = 0.06 to 0.86 mm, p = 0.02) when comparing sites with and without platelet-rich plasma (PRP) or platelet-rich fibrin (PRF). When evaluating the effect of adjunctive use of bone morphogenetic proteins (BMPs) at alveolar ridge augmentation sites compared to alveolar ridge augmentation sites without BMP application, the WMD of the horizontal bone gain at edentulous ridges was 0.90 mm (95% CI = 0.30 to 1.49 mm, p = 0.003). In addition, the odds ratio of the titanium mesh exposure was 0.13 (95% CI of 0.02 to 0.71, p = 0.02). All analyses showed favorable outcomes at the sites with bioactive agent. Conclusion: Within the limits of this review, application of bioactive agents during alveolar ridge augmentation procedures presents increased horizontal and vertical bone augmentative changes. The complication rate can also be reduced with usage of PRP/PRF in titanium mesh-guided alveolar ridge augmentation.
