Osseointegration is the format of a direct interface between an implant and bone, with out soft tissue in between the direct bone-implant surface bond. Dr. Hanah Pham often tells her patients that she usually has an idea if the implant is successfully osseointegrated at the 2-3 months follow up appointments, but the "Torque Test" at the time of restoring the implant a few months after the implant surgery. The manufacturer will give a specific torque pressure to tighten and turn screw that connects the abutment to the implant titanium fixture. Then an impression is taken to send to the lab. This is the most common way to do restore the implant, but certainly there are minor differences that can be done based on individual situation and needs. Dr. Hanah Pham has always been a pioneer in her techniques and she can tackle any difficult situation there is due to her advanced training in implantology and her flexible thinking "outside-the-box" since dentistry and medicine is not an exact science like we all know; sometimes, conventional ways do not work or make it impossible to achieve patients' wants and goals.
Although one longintudinal study shows the survival rate of dental implants over a 10-year observation has been reported to be higher that 90% in totally edentulous (no teeth) jaw and in jaws with teeth the success rate will be even be higher, dental implants do fail in some patients. Implant failure rate is low in the hands of a skilled implant clinician with proper planning and working up cases for measurement, anatomy location, bone quantity (done in all of Dr. Hanah Pham's implant cases).
Other factors that may cause implant failure are:
- The health of the patients - for example, uncontrollable diabetes can decrease in healing. Rest assure that Dr. Hanah Pham will always consult with our patient's MD should she feels that her patient's condition will interfere with the implant's treatment success.
- Severe osteoporosis (severe reduction in bone quality and quantity) in especially elderly females
- Chronic heavy smokers - this is usually not a huge factors with Dr. Hanah Pham's recommendation of not smoking for the first couple of weeks post implant surgery for early healing of the implant. Smoking decreases blood flow to the implant surgical site which is thought to cause decrease or delay healing, which were seen in Dr. Hanah Pham' s surgical and implant surgery cases.
- Periimplantitis - poor plaque control which is easy to control with patient's commitment to their oral health.
- Severe Bruxism - noncompliance by the patient from not wearing the bruxism splint to protect the implants and teeth from repetitive chronic pressure of nighttime grinding and clenching. Bruxism is controlled by both genetics and environmental factors and a very common parafunctional habit in today's society of social media and smart phones world.
