Abstract

This clinical report describes the retrieval of a malpositioned mandibular implant with a severe lingual inclination. A replacement implant was inserted with an emphasis on its relationship with the maxillary antagonist, resulting in a buccal inclination of approximately 10 degrees. The treatment review highlights the importance of thorough communication among all members of the dental implant team. (J Prosthet Dent 2002;88:255-8.)

Clinical report

A 34-year-old woman with bilateral loss of the posterior teeth was referred to the School of Dentistry at Nippon Dental University (Niigata, Japan) for implant treatment. After a clinical examination was performed, a treatment plan that involved fixed implant-supported restorations, with IMZ (Aspack Corp, Osaka, Japan) implants in areas of the mandibular right first and second molar and left first molar, was agreed upon. Bilaterally, each segment was to be connected to adjacent natural teeth

Summary

In the clinical situation reported above, an implant was placed in an incorrect inclination in spite of cooperation between the surgeon and prosthodontist. This failure suggests the necessity of clearly presenting the prosthodontic aspects of treatment to each member of the team before surgical treatment is rendered. For the patient described, removal of the implant with a trephine bur proved effective.
