FREE 1 CE WEBINAR - SEPTEMBER 22ND @ 7 PM EDT/ 7 PM CDT/ 7 PM PDT . Clinicians today want to eliminate possible dental implant restorative complications and fabricate restorations with longevity and reparability built into the design.  Ideally, all dental implant restorations would have the ability to be retrievable without compromising the integrity of the prosthetic and therefore screw retained.  Traditionally, a screw retained restoration required more accurate implant positioning and is accompanied with several advantages over a cemented restoration.  Benefits included known retention, ease of removal or re-tighten, retention of short teeth or when limited interocclusal space exists, and most of all, assurance of no lurking cement. 
 
The detrimental effects of residual cement can be catastrophic and have been well document in the literature. (Wilson 2009)  Many clinical cementation techniques are utilized in an attempt to control the amount of cement and to contain its subgingival migration.  However, the only way to be certain there is no cement present at the implant platform-abutment interface is to eliminate it from intra-oral use.  
 
The inability to angle all implants ideally for screw retention arises with the relationship of teeth to the relationship of bone or the lack of quality or quantity of bone.  In some cases, the available bone to establish initial primary stability is located in areas that will not allow the long axis angulation of the implant to be in an ideal position to allow a screw retained restoration. This is often the case on anterior implants where an immediate implant placement will give the best esthetic result. The need has existed for a screw retained prosthetic solution when the long axis of the implant does not coincide with the lingual or occlusal aspect of the final restoration.
 
Learning Objectives:
1. Understand the options available to utilize an angled screw channel hybrid abutment.
2. Understand the armamentarium needed for you and your lab to deliver an angled screw channel restoration.
3. Understand why angled screw channels are relative to you and your practice.
