The concept of prosthesis-directed implant-supported restorations in now fully recognized, increasing the importance of prosthodontics in the initial treatment planning. This article reviews the role of prosthodontics in planning and execution of the restoration, with focus on the vertical dimension and freeway space--the major components of macroaesthetics. The signs of ridge resorption and ridge extrusion are identified, and the methods of ridge correction are presented, including alveolectomy prior to fabrication of the prosthesis and the adjustment of the abutment height to the modified ridge.

Generational differences in implant prosthodontics: a biomechanical solution.

Correct placement of implants is facilitated by the parameters that are already established, dictated by the struts and borders of the existing implant frame. The root-form implants should be: Contained in the anterior symphysis of the mandible. Completely encompassed in bone, without any contact with the Vitallium frame. As long as possible, to enhance biomechanical support of the superimposed bar and prosthesis. Evenly dispersed, in order to support a Hader bar. Independent of the previous implant system. Placed to fill the anteroposterior spread as completely as possible. The rationale and approach should comprise these requirements in order to achieve a predictable solution to mechanical failure of a subperiosteal implant, in an efficient manner, with the least possible trauma to the patient.

Progressive prosthetic transference for root form implants.

The prosthodontic implementation of the concept of progressive bone loading for root form implants is addressed. The use of transitional prostheses of acrylic resin with reinforced cast substructures are utilized to promote progressive prosthetic transference in arches with as few as three remaining natural roots. Progressive prosthetic transference is a clinical execution of biologic, biomechanical, and physiologic principles that are compatible with the needs to foster and maintain osseointegration.

Parafunctional habits, nightguards, and root form implants.

Occlusal schemes and designs of fixed and removable implant prostheses must satisfy requirements for the innocuous vertical loading of root form implants. Parafunctional habits (clenching, bruxing, or engaging) can transmit forces to the supporting bone that may result in destructive lateral stresses and overloading. Most nocturnal parafunctional habits can be ameliorated by acrylic resin nightguards.
