Screws And Prostheses:


•Screw Mechanics

•Screws Loosening Mechanism In Implant-Supported Prostheses

•Complications Due To Screws

•Clinical And Laboratory Fabrication Steps of the Screw Retained Prostheses

•Possible Precautions Against The Screw Loosening


Implant companies mostly use screws to secure the prosthetic superstructures on implants. Several prosthetic components such as healing abutments, impression posts, standard abutments and so on are secured on the implants with the use of screws and these connection interfaces are the most delicate surfaces of implant-abutment compositions. Although clinically important, screws and their impact have been neglected in scientific meetings. Therefore, the aim of this lecture is to present some detailed information regarding screws and their impact on implant dentistry.

Learning Objectives

Treatment of Complete Edentulous cases with Cement/Screw retained Fixed Partial dentures by Dr. Gurkan
Treatment of Complete Edentulous cases with Implant Supported Complete Dentures (Overdenture) by Dr. Burak
Treatment of Complete Edentulous cases with All on 4 concept by Dr. Oguz

At the conclusion of this course, the participant will be able to:

  • Develop an appropriate treatment plan,
  • Evaluate the vertical dimension of occlusion,
  • Make interocclusal records for mounting of definitive and diagnostic casts,
  • Fabricate a provisional restoration to evaluate function, speech and esthetics and to serve as a guide for the dental laboratory technician when finalizing the anterior guidance.
  • Properly identify the different type of attachment systems for overdentures, including indications, contraindications and expected complications due to materials nature,
  • Determining the optimal number of implants required for implant supported Complete/Partial dentures.
  • Indications, Pros & Cons of All on 4 concept

Each step will be illustrated with clinical cases, step-by-step.


Abstract


Once the natural dentition is lost, it becomes challenging to restore function, phonetics and esthetics. Many diagnostic measures are required to develop a biomechanically favorable occlusion for any type of implant supported restoration. A diagnostic waxing and planning are critical because it permits the determination of the desired implant position and distribution. This waxing also becomes a template for the provisional restoration, which in turn, serves as a blueprint for the establishment of esthetics, phonetics and function in the definitive restorations.


Initially, implants are positioned almost perpendicular to
the occlusal plane; however, to overcome anatomic limitations at the posterior area, tilting posterior implants has been introduced. The technique consists of rehabilitation of either edentulous or dentate maxilla and/or mandible with immediate fixed prosthesis by placing four implants in the anterior region. This immediate prosthesis also plays an important role for the clinician to achieve better esthetics in the definitive restoration phase.


Dental Implant Occlusion

 

The dental literature is filled with publications on occlusion, however, these publications have information mostly empirical in nature and lacking evidence-based outcomes. This is particularly true for the scheme of occlusion to be used for implant-supported/retained reconstructions.

 

This presentation will focus on different occlusal schemes that have been recommended for implant-supported/retained prostheses. In addition, the impact of different occlusal schemes on the success of implant-supported/retained prostheses will be discussed.
