Implant bridge

implant bridgeAn Implant bridge is a fixed dental restoration used to replace a missing tooth by joining an artificial tooth permanently to or dental implants.
A dental implant is a root device, usually made of titanium, that support the restoration. Most of the dental implants placed today are root-form endosseous implants and they look similar to a normal tooth root and are placed within the bone that will osseointegrated with the titanium post.

Barring complication arising from bone or tissue disease, trauma, bad occlusion, patient neglect and rampant bacteria build up, nothing surpasses dental implants in having the greatest potential for having and maintaining near perfect oral health and dentition.

Strengths of the implant bridge

When replacing multiple missing teeth dental implant crowns are often preferred by patients to implant-supported bridges, since they allow patients to floss normally between the crowns and achieve better periodontal health.
A restorative dentist or specialist may recommend a dental implant bridge instead of individual crowns. The reason for this is that, due to anatomic limitations, replacing front teeth with crowns will often produce poor esthetic results.
Traditional implant-supported bridges can be utilized throughout the mouth eliminating placement of additional implant fixture in anatomically deficient areas or if chosen by the implant restorative dentist instead of individual tooth-for-tooth replacement.

  • It can be either screw retained or cemented on implant abutments.
  • Screw-retained prosthesis allows for removal of the bridge if needed.
  • Cemented bridge cannot be removed as it is on permanently; bridge abutments are made such that the path of insertion of the teeth involved is nearly parallel with each other.
  • An abutment is not necessarily parallel to the long axis of the implant.
  • It is utilized when the implant is at a different inclination in relation to the proposed prosthesis.
  • The abutment can be made from a variety of materials, such as titanium, surgical stainless steel and gold; More modern abutments are now also made from zirconia to better complement the aesthetics of a dental implant restoration.

The clinical longevity of an implant bridge

Whenever an implant-retained bridge is connected to implants, the clinical longevity and need for maintenance repair depends to a great extent on the precision of the manufactured components: non-passively fitting superstructures are still considered a potential cause for the high incidence of technical complications associated with these restorations.

In cement-retained implant superstructures, the cement layer can compensate for dimensional discrepancies between the abutment and the restoration to some extent, working as a filling medium to more uniformly transfer loads to the implant–prosthesis–bone complex.
