This case addresses the challenge of crestal bone loss around dental implants associated with thin peri-implant mucosa. To mitigate this, he utilizes botiss mucoderm®, a porcine-derived collagen matrix, as an alternative to autogenous grafts for soft tissue thickening. The procedure involves placing a Straumann® Bone Level Implant, followed by the application of the rehydrated mucoderm® matrix over the implant site. This approach enhances mucosal thickness, promoting better crestal bone stability and esthetic outcomes. The case underscores the efficacy of mucoderm® in augmenting soft tissue, thereby contributing to the long-term success of dental implants.
This case report shows the successful treatment of peri-implantitis using the GalvoSurge® Dental Implant Cleaning System combined with guided bone regeneration (GBR). A 66-year-old patient presented with peri-implantitis around implant #37, characterized by bleeding on probing, increased probing depths, and circumferential bone loss. Initial non-surgical interventions included prosthesis removal, installation of healing abutments, mechanical debridement, and antimicrobial irrigation. Subsequently, surgical treatment involved electrolytic cleaning with GalvoSurge®, application of a Straumann® Membrane Flex, and grafting with autogenous bone chips mixed with botiss maxgraft® granules. Over a two-year follow-up, the patient exhibited stable peri-implant conditions with no signs of inflammation or bone loss, underscoring the efficacy of this combined approach in managing peri-implantitis.
In this EAO 2019 Corporate Forum lecture, Dr. Puišys shares insights from over 15 years of experience in immediate implant placement, focusing on achieving predictable esthetic outcomes in the anterior region. He highlights the challenges of early techniques and the turning point brought by clinical trials and updated evidence. Central to his approach is the “four-millimeter rule,” emphasizing the need for sufficient buccal soft tissue thickness to maintain crestal bone stability. Through careful implant positioning, use of small-diameter implants, and tailored grafting strategies, Dr. Puišys demonstrates how to minimize complications and ensure long-term success. He also discusses the evolving role of grafting materials, including xenografts and dermal substitutes, and underscores the importance of individualized treatment planning based on anatomical conditions.
(With Dr. Viktorija Auzbikavičiūtė). The immediate placement of a Straumann® BLX implant in the posterior mandible of a 40-year-old patient is shown. The patient presented with secondary caries and subgingival destruction in tooth #36, rendering it non-restorable. Following atraumatic extraction and preservation of the interradicular septum, a 5.5 x 8 mm BLX implant was placed. The surgical site was augmented with allogenic bone graft (maxgraft®) and platelet-rich fibrin (PRF) to support healing. After four months, the implant demonstrated stable soft tissue integration, and a final zirconia ceramic crown was successfully installed, resulting in satisfactory functional and esthetic outcomes.
The use of botiss mucoderm®, a porcine-derived collagen matrix, to increase mucosal tissue thickness around Straumann® Bone Level Implants. The goal was to improve crestal bone stability and esthetic outcomes, particularly in cases with thin peri-implant mucosa. The procedure involved placing the implant and covering it with rehydrated mucoderm® to promote soft tissue thickening without the need for harvesting autogenous grafts. Results showed enhanced mucosal volume and stable bone levels, supporting the matrix's effectiveness in improving long-term implant success.
The strategies to enhance crestal bone stability following immediate implant placement in molar regions are explored and the complexities of achieving optimal outcomes in such procedures, particularly due to the anatomical challenges presented by molar extraction sites are explored. The importance of several key factors in ensuring successful implant integration and bone preservation is highlighted. These include performing atraumatic tooth extractions to minimize tissue damage, precise three-dimensional positioning of the implant to align with the patient's anatomy, and the use of individualized healing abutments tailored to the specific surgical site. Additionally, the role of implant design in influencing bone stability and the benefits of incorporating CAD/CAM technology and bone augmentation techniques to support the implant site is discussed. The webinar provides valuable insights into the complexities of immediate implant placement in molar areas and underscored the necessity of a comprehensive approach that considers surgical precision, prosthetic planning, and biological factors to achieve long-term success.
