Minimal invasive horizontal ridge augmentation with Calcium Sulfate bone cement: A case series

Abstract

Background: The objective of this retrospective study is to assess the minimal invasive technique for augmenting horizontal ridge or bone defects using biphasic calcium sulfate with hydroxyapatite bone cement. Methods: This study focused on 14 partially edentulous patients: 5 males and 9 females, aged between 36 and 82 years old. These patients were non-smokers and had no chronic diseases or received radiation treatment in the last 6 months. During their initial consultation, all patients underwent cone beam computed tomography. Horizontal bone augmentation was necessary for all patients to facilitate prosthetically driven implant surgery. Bond Apatite bone cement horizontal grafting was used for all patients, along with immediate or delayed implants (with or without immediate loading). One year after the final prosthetic placement, all cases were evaluated. The clinical progression of peri-implant volume and tissue quality was documented photographically, along with exams conducted every 6 months. The complete follow-up timeline for these cases ranged from 1 to 5 years. Results: A total of 34 implants were placed in the grafted zones, distributed among 14 patients. None of the patients reported any abnormal discomfort or swelling after surgery, and there were no infections or significant post-surgery complications noted. One year after the placement of various fixed prosthetic rehabilitations, all 100% of the implants remained stable with healthy peri-implant soft tissue and very satisfactory aesthetic results. Conclusion: The Bond Apatite bone cement has demonstrated exceptional effectiveness in reconstructing or augmenting horizontal defects and narrow ridges, increasing the available bone/soft tissue volume and soft enabling successful placement of implants, whether immediate or delayed, with or without immediate loading. Furthermore, the use of Bond Apatite resulted in minimal post-operative complications and an impressively low rate of postoperative infections, allowing for minimally invasive augmentation surgery, eliminating the need for extensive surgical flaps and free tension flap sutures typically associated with this type of procedure.
