In May, 400+ clinicians attended Straumann's day-long Dental Implant Complications symposium. Topics discussed including identifying and addressing implant complications, understanding the reasons they occur, determining treatment and solutions, and understanding how to avoid them through prevention methodologies such as proper planning, patient selection and timely treatment. Here are some highlights from one of the six presentations.
Dr. Dean Morton characterized prosthetic problems as the stepchild among implant complications. ?While they are very common in clinical practice,? Dr. Morton observed, ?they are rarely covered in the literature or course curricula.?
As with all types of implant complications, the factors influencing prosthetic outcomes are numerous. In general, most implant prosthetic problems can be traced back to lapses during the assessment and treatment planning phases, according to Dr. Morton. In addition, he listed and discussed the 10 most common areas to check out if prosthetic outcomes are poor:
1. Retentive elements for overdentures
2. Presence of cantilevers
3. Cement- vs. screw-retained implants
4. Angled/angulated abutments
5. Bruxism parafunction
6. Crown/implant ratio
7. Length of suprastructure
8. Prosthetic materials
9. Number of implants supporting a fixed prosthesis
10. History of mechanical/technical complications
Dr. Morton noted that fixed implant-supported prostheses with cantilevers are more likely to experience mechanical complication than non-cantilevered designs.
Dr. Morton summed up the take-away: ?The vast majority of prosthodontic complications are not related to the implant itself. While complications can be related to implant and component design, they are most often related to the manner in which the implants are positioned and utilized.?
