Seven technical advantages of 3i nano dental implants in the United States: 1, short operation time: the unique OSSEOTITE internal connection implant system overcomes the inherent weakness of the traditional internal connection implant system, which can shorten the treatment time, simplify the operation, reduce the cost and increase the predictability of the treatment effect. 2, fast healing time: SLA sandblasting acid etching reduction surface treatment process, effectively avoiding corrosion and degradation of implant surface. On the basis of double acid treatment, adding nano-scale calcium phosphate crystal deposition treatment can make the implant more stable, greatly shorten the healing time and be more suitable for immediate implantation. 3. Minimally invasive and painless: American 3i nano-implant not only combines nano, holographic detection and computer design technology, but also adopts minimally invasive implantation. The leading minimally invasive implantation method gets rid of the steps of cutting tooth meat, suturing and removing stitches in the traditional implantation method, and only needs a small incision to allow patients to complete the operation process in a comfortable, painless and relaxed state.
