Course Objectives (2 CE Credits)
Though mini implants are designed to accommodate the immediate loading of an existing denture in the presence of primary stability, patients are often better served by the fabrication of a prosthesis specifically fitted for the new biologic form factor. Presented with a patient whose mandibular denture had been heavily modified according to conventional denture techniques, Dr. Christopher Travis undertakes the process of fitting her with a new overdenture designed for optimal function and esthetics following the osseointegration of four mini implants. His appointment-by-appointment video and article detail the concerns for each step of the procedure, from preliminary impressions to final prosthetic delivery. Among the key concepts are:
- Implant and prosthetic hygiene
- Use and adjustment of provisional prosthesis
- Impression techniques and challenges
- Border molding procedures
- Vertical dimension of occlusion (VDO)
- Vertical dimension at rest (VDR)
- Bite registration
- Tooth selection (shade, mould, arrangement)
- Posterior spacing
- Esthetics and phonetics
- Bilateral balancing occlusion
The growing acceptance of mini implant-retained overdentures as a long-term solution in edentulous cases is providing new levels of comfort and satisfaction to an ever-increasing number of denture patients unwilling or unable to accept conventional implant treatment. The clinical success of any implant removable restoration, however, is highly dependent on the form and fit of the final prosthesis. Proper attention to detail at each stage of the prosthetic delivery cycle will help to ensure maximum benefit and patient approval.
CAUTION: When viewing the techniques, procedures, theories and materials that are presented, you must make your own decisions about specific treatment for patients and exercise personal professional judgment regarding the need for further clinical testing or education and your own clinical expertise before trying to implement new procedures.
