Dental Implant : Bone grafts in Dental Implantology

There are no absolute contraindications to implant dentistry, however there are some systemic, behavioral and anatomic considerations that should be considered. Uncontrolled type II diabetes is a significant relative contraindication as healing following any type of surgical procedure is delayed due to poor peripheral blood circulation. Anatomic considerations include the volume and height of bone available. Often an ancillary procedure known as a block graft or sinus augmentation are needed to provide enough bone for successful implant placement.

There are over 100 dental implant companies available on the U.S. market. The biggest and most reputable are Nobel Biocare, Straumann, 3i, Zimmer, Astra Tech, Ankylos and Bio-Lok. Specialists such as Periodontists or Oral/Maxillofacial Surgeons often play a role in the placement of implant fixtures. However, it is most appropriate for either a prosthodontist or general dentist to initiate and coordinate implant service, since they can best assess the merits of this treatment against other prosthetic options.
