Implant Crowns and Bridges
Implant Crowns refer to single tooth implant supported dental crowns. These typically involve a dental implant, an abutment and the crown that replaces the missing tooth.
When a Dental implant or multiple dental implants support multiple teeth this is referred to as an implant bridge.
When all teeth are missing is an arch and dental implants are used to replace 10-14 teeth this is referred to as an implant supported full arch solution. Full arch solutions can include 12-14 unit implant bridges that are fabricated from dental materials that replicate the natural teeth and gums as close as possible. The following image demonstrates a 12 Unit (12 Tooth) full arch bridge. This is also known as a fixed hybrid maxillary (upper arch) prosthesis. These fixed hybrid prostheses are typically screw retained with 4 or 6 implants supporting beneath. The fixed hybrid must be removed at least 1 time per year to have dental cleaning performed on implant and prosthesis, as well as clinical assessment of the dental implant.
Alternately full arch solutions can use acrylic material, essentially a denture. When a denture is supported by implants this is referred to as an implant supported complete over-denture. Often patients looking for implant supported full arch solutions will select an implant supported denture as they are more cost effective than a fixed hybrid solution. These dentures are removable allowing the patient to perform hygiene daily. In the upper (Maxillary) arch often 4 implants are utilized.
In the case of lower (Mandibular) dentures often 2 dental implants is sufficient to support the prosthesis. More implant often provide more support however many patient select 2 implant over-dentures for financial reasons. Many patients find 2 implant supported mandibular over-dentures areadequate for chewing and social function. Patient are able to add 2 additional implants later if the 2 implant solution is not providing adequate stability.
