Over recent years Dentistry has evolved, and as such, we have been able to make
strides in restoring edentulous patients with dental implants. Recently, the specialty
of Prosthodontics, in addition to the prosthetic rehabilitation of complex dental
patients with fixed, removable, implant, and cosmetic dental needs, has begun to
shift into the surgical realm of patient treatment. This report outlines a minimally
invasive technique for sinus floor elevation, on the controlled use of drills and
osteotomes, while simultaneously placing implants through a guided protocol. The
rational for such a technique is that it provides a predictable and repeatable method
of attaining vertical ridge augmentation as well as correct implant placement in
order to obtain ideal restorative reconstructions. In addition it provides the dentist
with the autonomy to treat patients requiring implants from start to completion
with a great deal of control. Postoperative radiographs reveal the amount of vertical
height gained and concomitant implant placements.

Questions:
 1) Vertical ridge insufficiency near the maxillary sinus may be caused by all of the following except which one:
  1. Trauma
  2. Malooclusion
  3. Posterior maxillary tooth extraction
  4. Pneumatization of the maxillary sinus
 2) Which is the most common procedure performed to increase bone volume in the maxillary sinus:
  1. Indirect approach (Summer’s)
  2. Caldwell-Luc procedure
  3. Direct lateral approach (Tatum)
  4. Endoscopic sinus approach
 3) Which of the following is an advantage of the
Indirect/transcrestal approach when performing sinus augmentation:
  1. Decreased post operative morbidity
  2. Direct vision of the Schneiderian membrane
  3. Quantity of augmented bone
  4. Decreased occurrence of membrane perforation
 4) A proposed tooth try-in was conducted to assess which of the following:
  1. Ideal tooth positions
  2. Phonetics
  3. Esthetics
  4. Vertical dimension of occlusion
  5. All of the above
 5) At what depth should the osteotomy be prepared beneath the antral floor when performing the Indirect/transcrestal
approach:
  1. .5mm
  2. 1.0mm
  3. 1.5mm
  4. 2.0mm
