Abstract

Implant overdenture treatment using several solitary attachment systems on mandibular edentulous patients. Most patients with severe residual ridge resorption report significantly more problems adapting to their mandibular denture due to a lack of comfort, retention, stability and to the inability to chew and eat. Recent scientific studies carried out over the past decade have determined that the benefits of a mandibular implant overdenture are sufficient to get retention and stability. Therefore, overdenture with implants on the mandible and attachments are considered as a treatment of choice as a favorable treatment. In this cases, with consideration for jaw relation, level of bone loss, facial support and economic factor, edentulous patients with severe residual ridge resorption are rehabilitated by complete denture on maxilla and two-implants overdenture using several solitary attachment systems on mandible.

• 

  Fig. 1 Initial panoramic view of the first patients. Generalized alveolar bone loss and multiple missing of teeth state are found.

• 

  Fig. 2 Diagnostic casts of first patient. Implant installation with healing abutments was found on both mandibular canine area.

• 

  Fig. 3 Intraoral views after implants placement with healing abutment adaptation. This patient with Class III had relatively narrow inter-occlusal space.

• 

  Fig. 4 Border molding and final impression.

• 

  Fig. 5 Establishing the occlusal plane and taking the face-bow transfer. Frontal line was parallel to the inter-pupillary line, lateral line is parallel to Frankfort horizontal plane.

  Fig. 6 Final dentures and installation of retention part of KERATOR attachment (Circles of dot indicate laboratory black male cap).

• 

  Fig. 7 Intraoral views with final dentures. All teeth contact opposite side evenly on centric relation.

• 

  Fig. 8 Panoramic view of the 2nd patient at implants installation on mandibular both canine area.

• 

  Fig. 9 Intraoral views after implant placement with healing abutment adaptation. It shows that direction of implants is non-parallel.

  Fig. 10 Final dentures and installation of retention part of EZ-LOCK attachment on final denture (Circles of dot indicate EZ-LOCK metal housing).

• 

  Fig. 11 Panoramic view of the 3rd patient with fully edentulous state on maxilla and mandible. As posterior teeth of mandible have been missing for a long time, severe residual ridge resorption was found.

• 

  Fig. 12 Intraoral views after implant placement with healing abutment adaptation. It shows that severe resorption of alveolar ridge on mandibular posterior area.

  Fig. 13 Final dentures and installation of retention part of magnetic attachment on final denture (Circles of dot indicate magnetic attachment).
