Implant placement above a bifurcated mandibular canal: a case report.

Accurate radiographic assessment of available bone dimension superior to the mandibular canal is essential to the favorable placement of dental implants. Panoramic and periapical radiography are the standard of care. They typically offer a clinically adequate interpretation of the canal topography. However, in about 1% of patients, the mandibular canal may bifurcate. This may or may not be seen on panoramic or periapical films. A case report is presented that uses complex motion tomography as an aid to proper implant placement above a bifurcated mandibular canal.

A maxillary implant overdenture that utilizes angle-correcting abutments.

Placement of dental implants to enhance complete denture stability and retention is a well-accepted treatment modality. Most implant overdenture abutments and related components require parallelism within approximately 10 degrees to function properly. Non-parallel implant placement as a result of flared maxillary bone may preclude the use of conventional implant overdenture abutments, requiring the use of costly custom abutments or bar prostheses. A case report is presented that illustrates the use of a new, 2-piece, angled overdenture abutment to accommodate non-parallel implant placement.

Electronic monitoring of dental implant osseointegration.

BACKGROUND: The methods for evaluating dental implant osseointegration can be limited in their effectiveness. The authors developed a new noninvasive electronic instrument to test implant stability and improve the assessment process. METHODS: Using the new instrument, which was based on impulse testing and fast Fourier transform, or FFT, technology, the authors tested implant stability under real-time clinical conditions. The clinical procedure involved a weekly test of two placed implants, from the first-stage insertion point to the completion of the integration. This longitudinal monitoring spanned eight months. RESULTS: The authors verified clinical implant integration electronically and that it closely matched mathematical predictions. They also observed changes in implant stability during the integration process. CONCLUSIONS: Implant stability can be monitored electronically using FFT testing. A theoretical integration prediction also can be formulated. Like a "dental electrocardiogram," integration is assessed by waveform shape analysis. CLINICAL IMPLICATIONS: Electronic measurement of implant stability may help clinicians noninvasively diagnose the suitability of implants for restoration and aid in postrestorative monitoring.
