Together with leading clinicians worldwide, Straumann has studied the clinical performance of SLActive® implants under the most challenging medical conditions and treatment protocols to demonstrate the outstanding healing capacity of the SLActive® surface.
As new insights emerge and new data becomes available, discover how you can benefit from the high performance SLActive® surface to support your patients’ healing capabilities.
Immediate loading allows the patient to benefit from the restoration straightaway after implant placement.
However, this demanding protocol carries a higher risk of implant failure.
Ever increasing patient expectations continue to drive demand for faster and more efficient treatment protocols. Immediate loading allows the clinician to place an implant and prosthetic restoration on the same day, so that the patient can benefit from the restoration straightaway. However, this demanding protocol carries a higher risk of failure due to premature loading of a healing implant.
One of the most challenging patient groups for implant treatment includes patients who have undergone a combination of tumor surgery, chemotherapy and radiotherapy. The bone quality in these patients is severely compromised.
Irradiation leads to decreased bone vascularity4,5, impaired osteoblastic activity6 and reduced bone vitality7,8, which severely compromise bone quality in these patients. The fragile mucosa and the risk of osteoradionecrosis present further challenges.
However, from a quality-of-life perspective, this patient group stands to benefit the most from implant- supported prosthetic rehabilitation.
- 102 implants, 20 patients
- Post-surgery, radiotherapy and chemotherapy for oral carcinoma
** Adjusted, excluding the patients deceased due to cancer mortality.
- Patients with diabetes have reduced wound healing capacity,15,16 which puts implants at risk
- Worldwide, 1 in 6 adults 60 years of age and older has diabetes.17
Worldwide, 1 in 11 adults has diabetes, while among adults 60 years of age and older, the prevalence is twice as high.17
Over the past 30 years, the number of people with diabetes in the US has quadrupled and, according to the US Center for Disease Control (CDC), the figure could increase to as many as one in every three adults by 205018. In an estimated 50% of people with type 2 diabetes, the disease remains undiagnosed.17
Given the ever rising prevalence of type 2 diabetes, how can clinicians address this risk particularly in older patients?
GROWING CLINICAL EVIDENCE OF highly predictable PERFORMANCE OF SLActive® IN DIABETIC PATIENTS:
A new clinical study19 that compared SLActive® performance in patients with and without diabetes showed uncompromised performance of SLActive® implants:
- 100 % implant success rate in the diabetic group
- Bone changes similar to those in healthy individuals
- Despite the observed lower levels of bone quality all implants in this study showed good primary stability.
- Roxolid SLActive® surface stimulates an early anti-inflammatory cell response20
- SLActive® is associated with an increased anti-inflammatory macrophage response in the early healing phase in both healthy and diabetic animals. This may be an important mechanism to improve osseous healing under compromised systemic conditions.21
