Join BioHorizons at the ICOI World Congress XXIX in Orlando, Florida, September 20-22, 2012 during ICOI's 40th anniversary. This international meeting, held at the Marriott World Center Hotel, will include top thought leaders who will discuss a wide array of dental implant and oral reconstruction topics. Attend our Pre-Congress Course on Thursday with Dr. Carl Misch who will present "Controversies in Implant Number" from 9:00 am - 12:00 noon. Visit BioHorizons on the show floor at booth number 401/403, to learn more about new products and materials.

Controversies in implant number
presented by: Dr. Carl Misch

In every treatment plan for missing multiple teeth there are key implant positions, which are more important, related to biomechanics. There are four guidelines to determine these positions. 1) No cantilevers; 2) No use of 3 adjacent pontics; 3) The canine and first molar rules; 4) Arch dynamics. Cantilevers are force magnifiers. Three adjacent pontics not only overload the adjacent abutment, the flexure of the metal is 27 times the flexure of a 1 pontic prosthesis. The canine and first molar are key positions for an arch, and whenever missing should be replaced with an implant (rather than a pontic). Arch dynamics (especially for a maxilla) require the structure to be considered as a 5 sided open pentagon. At least 1 implant in each section is required for each edentulous segment. Once these key positions are determined, the additional implants required to restore the patient are considered based upon patient force factors and the bone density in the edentulous sites.
