Abstract
The technique for fabricating an accurate implant master cast following the 12-week healing period after Teeth in a Day R _ dental implant surgery is detailed. The clinical, functional, and esthetic details captured during the final master impression are vital to creating an accurate master cast. This technique uses the properties of the allacrylic resin interim prosthesis to capture these details. This impression captures the relationship between the remodeled soft tissue and the interim prosthesis. This provides the laboratory technician with an accurate orientation of the implant replicas in the master cast with which a passive fitting restoration can be fabricated.

Zygomatic implants as a rehabilitation approach for a severely deficient maxilla

Al-Thobity AM, Wolfinger GJ, Balshi SF, Flinton RJ, Balshi TJ.

Int J Oral Maxillofac Implants. 2014 Nov-Dec;29(6):e283-9. doi: 10.11607/jomi.3662. Epub 2014 Aug 20.

Abstract: A gunshot injury is one of the main trauma injuries that affect the head and neck region. Severe esthetic, functional, and psychologic deficiencies are consequences of gunshot injuries. The use of implants anchored in the zygomatic bone has been advocated as an approach to the prosthetic rehabilitation of a severely deficient maxilla. This approach provides the patient with an immediate, high-quality, esthetic, and functional complete fixed prosthesis and eliminates the need for bone grafting. In this case report, a patient with a severely deficient maxilla caused by a gunshot injury was rehabilitated by placement of  four zygomatic and two pterygomaxillary implants, which were immediately loaded with a complete fixed all-acrylic resin interim prosthesis. The definitive CM Prosthesis (CM Prosthetics) was constructed using computer-aided design/computer-assisted manufacture (CAD/CAM) technology.

A Retrospective Analysis of 800 Brånemark System Implants Following the All-on-Four™ Protocol

Purpose: The purpose of this study was to retrospectively evaluate implant survival rates in patients treated with the All-on-Four™ protocol according to edentulous jaws, gender, and implant orientation (tilted vs. axial). Materials and Methods: All Brånemark System implants placed in patients following the All-on-Four™ protocol in a single private practice were separated into multiple classifications (maxilla vs. mandible; male vs. female; tilted vs. axial) by retrospective patient chart review. Inclusion criteria consisted of any Brånemark System implant placed with the All-on-Four™  protocol from the clinical inception (May 2005) until December 2011. Life tables were constructed to determine cumulative implant survival rates (CSR). The arches, genders, and implant orientations were statistically compared with ANOVA.

Results: One hundred fifty-two patients, comprising 200 arches (800 implants) from May 2005 until December 2011, were included in the study. Overall implant CSR was 97.3% (778 of 800). Two hundred eighty-nine of 300 maxillary implants and 489 of 500 mandibular implants survived, for CSRs of 96.3% and 97.8%, respectively. In male patients, 251 of 256 implants (98.1%) remain in function while 527 of 544 implants (96.9%) in female patients survived. Regarding implant orientation, 389 of 400 tilted implants and 389 of 400 axial implants osseointegrated, for identical CSRs of 97.3%. All comparisons were found to be statistically insignificant. The prosthesis survival rate was 99.0%.

Conclusions: The results from this study suggest that edentulous jaws, gender, and implant orientation are not significant parameters when formulating an All-on-Four™ treatment plan. The high CSRs for each variable analyzed demonstrate the All-on- Four™ treatment as a viable alternative to more extensive protocols for rehabilitating the edentulous maxilla or mandible.

A Retrospective Analysis of 110 Zygomatic Implants in a Single-Stage Immediate Loading Protocol

This clinical study using a specific technique was carried out to determine the clinical effectiveness of zygomatic implants under an immediate loading protocol. All patients treated between May 2000 and October 2006 who received zygomatic implants were included in this retrospective analysis. All patients were treated using the same surgical and restorative protocol. The following data were recorded: gender, age, type of implant, number of implants placed, dimensions of implants, and implant and prosthesis survival. Fifty-six consecutive patients (29 women, 27 men; mean age of 60.58 years [range, 38.78 to 84.01]) were treated. All were in need of oral reconstruction and had maxillary atrophy that warranted zygomatic implant placement. One hundred ten zygomatic implants were placed in these 56 patients. Four of the 110 zygomatic implants failed, resulting in a cumulative survival rate of 96.37% with follow-up data no less than 9 months and in excess of 5 years. All four failures were turned-surface zygomatic implants. There have been no failures to date with the titanium anodized-surface zygomatic implants. The prosthesis survival rate was 100.0%. In this retrospective analysis of 56 patients receiving 110 zygomatic implants, the survival rate of zygomatic implants was in excess of 96% over a period of 9 months to 5 years. This technique resulted in a stable and predictable prosthetic reconstruction.
