Cement or screw retained?

 

We are often asked our opinion as to whether a crown should be cement or screw retained. Although a screw retained prosthesis is often chosen when dealing with cases with limited inter-arch space, should it be utilized routinely? An article in the September/October issue of the International Journal of Oral and Maxillofacial Implants by Nissan et al in Tel-Aviv studied the complications associated with screw versus cement in implant-retained 2 and 3 unit splinted crowns. The prostheses were studied on 221 implants in 38 patients at an average of 5-6 years after restoration. Results showed increased ceramic fracture, abutment screw loosening, gingival index and marginal bone loss in the screw-retained group. Although this is only one study with a limited number of patients, it should help provide some food for thought when we deal with this everyday dilemma in the field of implant dentistry.

OSTELL ISQ-

New technology that ensures that that the implants we place are integrated and ready to be restored.

This device objectively measures the stability of a dental implant at the time of placement and at 2nd stage.

Based on resonance frequency analysis (RFA), the Ostell unit measures the implant stability quotient (ISQ). This number suggests the ability of an implant to resist lateral forces whcih are the forces that typically cause osseointegration to break down and cause an implant to loosen. 

Why is it important to measure implant stability?
Some reasons include:

1.  It supports making good decisions about WHEN to load
2.  It supports if immediate loading is possible at implant placement
3.  It can indicate situations in which it is best to UNLOAD 
4.  Supports good communication between surgeon, restorative doctor and the patient

Please call or email us if you would like any additional information about this new technology.  We strive to continue to provide the best care your patients!
