Diagnosis and Treatment

Implant Treatment

Titanium implants are buried in the mandible to supplement lost teeth.  Artificial teeth will be affixed to the implants, giving “biting power” and “appearance” close to natural teeth that you cannot obtain from bridges and false teeth.  If we take the biting power of natural teeth to be 100%, bridges only offer 50% and false teeth 30%. Implants can bear 90% and more. Yet, it cannot beat natural teeth. However, like it was mentioned before, in order to bear the burden of biting of the lost teeth, we should avoid damaging natural teeth as much as possible. Implant treatment exists for that reason, making it possible to protect the natural teeth.  Treating and scraping teeth means losing the value of teeth. Continuing to lose their value leads to destruction of the entire bite. As much as possible, treatments should not be repeated and it’s important to think carefully of which treatments are needed in order to keep protecting the treated teeth.

Bite Treatment

No matter what dental treatment, adjusting bite problems is very important. If you ignore bite problems, it destroys the teeth line, and the surrounding teeth and prosthetics wears down and break. Bad bite problems cause a disorder of the mind and body, making a second treatment necessary. Also, cavities and gum disease are not only sources of bacterial infection, but it may also result in damaged teeth tissue due to excess biting power, creating a foothold for infections.

Cavity treatment is a very delicate operation, where just shaving off a few millimeters off the teeth can change the bite, so bite adjustment is necessary for implant/correction/ceramic treatments. Regular balance adjustment leads to long-term mouth stability.

Advanced Regenerative Medicine

Ⓒ BTI Biotechnology institute

High-level regenerative implant treatment
The Endoret Implant treatment is an implant treatment that uses regenerative technology that regenerates bones and soft tissue using the safe and revolutionary PRGF-Endoret method. The power of cells in the blood becomes necessary in order to regenerate bones and mucous membranes. This high-level of regenerative treatment makes effective use of regenerative proteins in the blood to enable faster and more precise regeneration. The PRGF-Endoret method is widely accepted not only in Europe but also in the States as a technique that regenerates the alveolar bone. It is not only used in the dental field but also in sports medicine for top athletes and anti-aging in dermatology and cosmetic surgery.

Those who take implant treatments, those whose bones have worn down due to gum disease, those with teeth pulled out and wish to add bones in those parts, can be candidates for various oral surgeries. Our clinic has passed strict examination and is recognized as a certified agency of the Ministry of Health, Labour and Welfare.
