Benefits of a Bone level, screw retained, engaging Fixed dental Prothesis
1. Eliminates all prosthetic components that might otherwise be necessary between the implant bridge and each implant; 2. accommodates more extreme angulations than traditional custom solutions, without compromising a positive long-term outcome; 3. with digital scans and CAD/CAM production, and after a few cases experience, snaps into place without a try-in and adjustment; 4. requires fewer “through the prosthesis” screw channels (given the prosthesis inherent “snap in” retention), 5. makes an abutment-less connection routine, secure, long lasting, very easy for the Restorative Doctor, even in extremely divergent implant cases;
The BioHex Implant & Restoration System is the result of over 25 years of clinical research and was developed to overcome the many challenges associated with traditional implant systems.
This implant placement concept uses a dental alveolar approach and not the current maxillo-facial approach; this approach virtually eliminates 90% of bone grafting for the purposes of placing implants, (one restorative component, one-stage surgery, one-piece implant) and flexibility (the ability to predictably and simply restore all implant cases regardless of implant trajectories) of the system. Combination of all these makes it possible for general dentists to play a larger role in implant dentistry.
Multi-functional Healing abutment used as permanent Abutment to support a single cemented crown due to implant labial trajectory.
Physiological basis for dental implant treatment planning – how many implant and where?
No excessive Pressure can be exerted between healthy bone and tooth root(s) for vitality.
Nature vary the teeth biting surfaces and their supporting roots in order to deliver different biting forces
Between the front, middle and back part of the jaw.
Human evolution or nature provides the most efficient set up for function and survival. Our skeletal or bone are to support human forms and function, the vital bone cells must not be exposed to excessive pressure from forces that are acting on them.
Newton third law of physic stated that: To every action there is always opposed an equal reaction, that is to say that the equal and opposite reaction to the biting and chewing will be exerted by the roots that are supporting the teeth.
Due to the shape of the front teeth/root shape, the forces exerted in this area is relatively small about 10-15 Kgf so as not to exert too much pressure on the jaw bone.
As the biting force increases toward the back part of the jaw up to 100 Kgf, the surface area of these teeth increases and they also evolved into multiple roots in order to dissipate the pressure from these larger forces. So in effect, during mastication, all teeth will maintain their relative force to area ratio or pressure in order not to exceed the philological limits of the surrounding bone.
In an effort to reduce occlusal overloading especially in posterior region which might be the main causes of implant complications such as peri-implantitis, bone loss, prosthetic and implant complications.
Replacing all dental roots for multi-rooted molars with one-piece dental implant. 15 years follow up revealed bone loss of (0.06710732 mm SD 1.1610) around implants supporting single multi-rooted crown with manageable prosthetic and implant complications. Suggesting this approach is safe and effective
