A Standardized Protocol For Successful Mandibular Implant Overdentures

By Marwan DAAS, André ASSAF, Karim DADA

In a recent meeting at McGill University (Canada)1, a consensus was reached concerning the mandibular overdenture retained by two symphyseal implants. It must now be considered the minimal prosthetic treatment that most edentulous patients should expect from their dentist. However, the implant procedure must follow a well-controlled protocol since its success is neither the goal in and of itself nor is it a solution to the prosthetic handicap. Placing the implants is only the means to foster a higher success rate for the denture2.
Beyond the psychological problem related to its removability, the mandibular implant overdenture (MIO) is considered by many patients to be satisfactory on the aesthetic and functional levels, together with the comfort and ease of maintenance that it provides 3-4. If this treatment modality meets a certain number of criteria, it will be able to respond to the demand of a large number of totally edentulou…

Refining Occlusion with Muscle Balance to Enhance Long-term Orthodontic Stability

By Dr. Derek Mahony
The primary objective of orthodontic treatment is the movement of teeth into a more ideal relationship, not only for aesthetic, but also for functional considerations.  Another very important objective, often not given enough consideration, is the need to finish the case with the muscles of mastication in equilibrium.  If muscle balance is not achieved,  an endless procession of retainers, is required for retention.  In simple terms, if the occlusal forces in maximum intercuspation are unevenly distributed around the arch, tooth movement will most likely occur.  However, today it is possible to precisely measure the relative force of each occlusal contact, the timing of the occlusal contacts and specific muscle contraction levels, all simultaneously.  This technological breakthrough represents a new opportunity for orthodontists everywhere.
