Description: Obtaining an accurate interocclusal record which relates the upper and lower jaws to one another is critical in the laboratory production of dental restorations. This may be particularly challenging when the configuration of missing teeth dictate that such records are dependent on the remaining mucosal tissues for support. This article presents a practical and time saving method of using implant healing abutments, located within an edentulous distal extension space, to serve as vertical stops for an interocclusal record.

1. Most fixed dental restorations are fabricated to complement:

a. Centric relation position
b. Eccentric excursion position
c. Maximum intercuspal position
d. Physiologic rest position

2. An interocclusal registration made with the teeth in the opposing arches apart may frequently result in:

a. A distalized jaw position
b. A protruded jaw position
c. A neutralized jaw position
d. A lateralized jaw position

3. Jaw relation records which rely on support by the soft tissues of the mouth:

a. Are required when too few teeth are present to relate the casts
b. Necessitate an additional appointment to construct a trial base
c. Are inherently less accurate due to tissue compression potential
d. All of the above

4. This article presents a technique for using Methyl methacrylate resin as an occlusal registration media. The reason for making a primary segment first and placing it in a pressurized water bath is to:

a. Enhance polymerization
b. Limit expansion
c. Disinfect
d. Promote synerisis

5. The advantages for using the described technique include each of the following except:

a. More accurate than a mucosal supported record
b. Inexpensive registration media
c. Reduces need for an additional appointment
d. Less sensitive to operator error
