This article re- views one such problem known as Combination Syndrome. The treatment method described involves using a fixed mandibular prosthesis over implants that have been placed immediately after extraction.
Kelly first described Combination Syndrome in 1972 as destructive changes in hard and soft tissues of patients with complete maxil- lary denture opposing an unstable bilateral free-end mandibular partial denture.1, 2 In different words, Combination Syndrome is a description of a dental condition that is the result of long term use of a few, usually6 remaining lower anterior teeth, #22-27 and a complete upper denture with no other natural remaining teeth and a lower free end Kennedy class I removable partial denture.
Combination Syndrome is an aggressive occlusal problem that slowly develops over time.
This case study deals with treatment of Combination Syndrome. Understanding the cause can assist the practitioner in preventing further residual ridge deterioration.
The assessment of the risk of developing the combination syndrome depends on past dental history, the condition of the remaining mandibular anterior teeth, and posterior lack of occlusal support.
