The negative impacts of oxidative stress on Dental Implants
Oxidative stress generates cell damage and tissue destruction which can have a detrimental effect on Dental Implants.
Oxidative stress is a cell aggression generated by accumulation of free radicals also named oxidants. The biological reaction of cells is to produce antioxidants in order to neutralise the oxidants.
Main factors accountable for high oxidation level
- ischema
- inflammation and biological situations where the body is unable to produce enough antioxidants such as: smoking, diabetes, hypercholesterolemia
- Vitamin-D deficiency, etc..
The healing of dental implants and bone grafts depend on the quality of new vascularization, however the long term stability requires the maintenance of blood supply and adequate biologic functions in the reconstructed area during the whole life.
PRF course with the inventor Dr. Joseph Choukroun
25-26th March, 2022 London
- Dr. Choukroun’s upcoming Platelet Rich Fibrin -PRF- course is an enlightenment on the biological and mechanical conditions for long term stability and success of bony and soft tissue management.
- Learn about PRF use in dental implantology, oral surgery, bone graft. Prepare PRF products on the hands-on session, practice phlebotomy and start utilising PRF from the next day in your dental practice.
Factors which have significant impact on chronic oxidation
- Vitamin-D and cholesterol level. These have high impact on the outcome of dental surgery as these are the key factors to reduce oxidation and increase antioxidants production.
- The choice of biomaterials: variable compatibility, the ranking is scientifically grounded.
- The management of flaps is one of the main factors of tissue maintenance. Too much tension creates extensive oxidation: the novel Soft Brushing technique was introduced by Dr Choukroun which increases the flap laxity without periosteal incision or bleeding.
- Tension arised from the vestibule in the margins: avoid tension with Specific suture protocols will be explained by Dr Choukroun on the PRF course
- Adapted insertion torque during Implant placement according to bone density, particularly after bone grafting.
- Reduce ischemia of the flap and improve angiogenesis in the bone graft with the use of sticky bone (A-PRF) and stem cells from the blood (i-PRF) injected during surgery. These new techniques will be presented by Dr Joseph Choukroun.
- The reduction of pressure applied by the flaps during procedures of bone augmentation is the key for success.
All these procedures will allow the surgeon to achieve long term stability of the bone graft and the dental implant.
