Varioss Basal Anchor Implant
Varioss implant has two types of thread profile
1. Cortical Thread 2. Cencellous Thread.
CORTICAL THREAD
The Ultimate goal of Dental Implant is to perform well under occlusal load, for a long time, without overloading the bone or implant, this is the only parameter for the Surgeon & Patient satisfaction. Quality of bone is not in our control but the implant design is. By focus on Biomechanical principles we have developed a Basal Implant that would situate the surgeon in condition of Place & forget, implant would take care of its survival.
Cortical threads at distal region of implant that engage in cortical bone. Cortical threads have deep and sharp thread angle which allows threads to wedge easily in hard cortical bone
Cencellous Threads at superior region to Cortical Threads that engage in Cancellous bone in alvelor region. Cancellous Thread is a combination of two threads, Base thread and top thread which is small sharp thread formed on the top of base thread.
Cencellous Thread has 3 distinct features.
- Cencellous thread’s Minor thread diameter is bigger than Cortical Thread
- Cencellous Threads are broader and shallower than Cortical Thread
- Conical Thread profile
Cancellous Thread

Varioss Advantages
Effective cortecalization of cencellous bone is resulted by chain of action.As the process of screw insertion, first cortical thread are comes in a contact with cencellous bone, bone is displaced according to sharp and deep thread pattern, this formed pattern is further expands and bone is compressed at 3 points when comes in the contact with cencellous thread.
- First point of bone compression achieved at base of cancellous thread because its minor thread diameter is bigger than cortical thread.
- The sharp and deep cavity that was originally formed by cortical thread is now broadened by cancellous thread because its thread profile is broader than cortical tread.
- Finally conical thread profile expands the cencellous bone because threads major and minor diameter increases as a screw progress in the cancellous bone. Conical thread profile has another advantage that is every thread remains in full contact with bone after final fixation.
- As we know that Cancellous thread is a combination of two threads, Base thread and top thread which is small sharp thread formed on the top of base thread. This top thread is formed to increase grip of cancellous thread in the corticalized cancellous bone.
Implant –Bone behaviour in dynamic occlusal loading.
- Cortical bone is less likely to resorb under dynamic loading condition. Cortical thread allows more bone between two threads that promotes good stability in cortical region. Most of the occlusion forces are grounded to hard cortical bone.
- Load sharing is done by corticalized cancellous bone at cancellous thread region the purpose is to achieve load sharing and prevent overloading of hard cortical bone and prevents implant failure.
- We all know we can easily cut an apple with the sharp knife and it is very difficult to cut an apple very blunt knife, here shear force principal applies. Bone is weakest in shear force and broad and shallow cancellous threads transfer less shear force under dynamic loading. Thus corticalized Cancellous bone also prevented from overloading.
More stable basal anchor implant, load distribution in larger surface area, Effective Corticalization of cencellous bone, stress relieving and distribution principal applied to prevent bone resorption and implant failure, Patient centric approach
Varioss implant is 100 % more stable under osslusal load comparing to any other Basal Implant available in the market.
