Preventing and resolving complications with osseointegrated implants.

Zarb36 has stated: "The technique of osseointegration is supported by compelling evidence of clinical longevity. It is an outgrowth of good science, painstakingly investigated, and meticulously executed. The success of edentulous patient treatment augers well for a diversified application of the technique." Along with scientific advancement and diversification of applied technologies are equally diverse challenges. A variety of potential complications, using osseointegrated implants, have been discussed. The objectives of this discussion is the development of concepts to prevent complications through careful treatment planning and meticulous execution of surgical and prosthetic treatment techniques. The six major categories of potential complications include: (1) esthetic, (2) phonetic, (3) functional, (4) biologic, (5) mechanical, and (6) ergonomic. The most frequently observed difficulty with any implant prosthesis relates to esthetics in the maxillary anterior and is followed then equally by phonetic, functional, biologic, and mechanical. Ergonomic complications should be minimal with continued improvement in instrumentation and clinical techniques. Complications are but a challenge to our professional knowledge and ingenuity. Ultimately they benefit both patient and profession alike.
